Pros: *Games that supports HDR looks awesome!
*Games that doesn't support HDR still looks awesome!
*4k with Gsync works extremely well together even if you don't have the GPU power to go 144Hz in 4k--gameplay remains silky smooth!
*Depending on your preference, can be set up with colors as vibrant as you want or eye searing brightness as much as you want.
*Thinner bezels than the Asus PG27UQ.
*Better stand than the Asus PG27UQ IMHO. (It takes less space and its solidly built)
If you seriously considered buying this monitor, given the high price, I'm sure you have done your homework. Currently there are only two monitors in the world that offers: 4k, GSYNC, HDR, 144Hz, IPS, etc. in one package--the Acer Predator X27 and Asus PG27UQ.
My previous monitor is the Acer Predator x34 which I loved very much and was lucky enough to get a perfect one without any dead/stuck pixels and very minimal BLB. Prior to that monitor, I've also owned the other older version of Asus & Acers 144Hz & 165Hz IPS GSYNC monitors which unfortunately I have to return several times (At least 3 times on the Asus and twice on the Acers) to get a perfect acceptable one. It's such a hassle to return monitors but I'm not afraid to do so in my conquest in getting a monitor I'm completely satisfied with.
Now coming back to this Acer Predator X27, I've started monitoring it since the prototype first appeared in CES 2017. I mean its like a gamer's dream come true--4k, 144Hz, Gsync.... the HDR and FALD was a bonus for me. I'm usually an early adopter of new bleeding edge tech. I didn't mind paying a premium. That's just how it is on new techs like this. The same can be said for my Predator X34 when I first got it for around $1.3k. It didn't go down much at price at all even though its been a few years--it's still around $1k. For the x27, I started saving for it early and was ready to fork up to $3k for it. I know its a lot of money for a monitor but if I'm not satisfied in any way, I have no problem just sending it back for a full refund and just wait again for a better tech to come around.
I'm very happy to say though that I feel I got extremely lucky on the monitor lottery this time around. I absolutely don't have any BLB even when FALD is turned off (I know! Its hard to believe!) and there are no dead/stuck/bright pixels (believe me, for $2k, I Iooked for it). HDR in games that supports it looks superb. Even when watching HDR videos in Youtube you can see the big difference. For example, I was watching this concert in HDR and the lights on the stage when it got focused on the camera almost feels like I was there at the concert coz of how blindingly bright it is! Thanks to local dimming zones, the contrast is almost as good as OLEDs. Its hard to run 4k in high refresh rate but Gsync makes sure gameplay stays silky smooth as long as fps doesn't dip too low.
Cons: *Only few games at the moment supports HDR
*No single GPU solution currently exist that can drive 4k at 144Hz
*Turning on HDR in games can be a hassle (read more info. below)
*Blooming of bright objects in dark backgrounds can be distracting to some people
*While the stand is solidly built with steel, the main monitor casing feels cheap for a premium 2k monitor
*Built-in fan can be too noisy to some people
*Still suffers from QC issues (Almost every new released monitor suffers from this)
*No pivot option to move the monitor unlike the Asus PG27UQ.
*Black crush when running monitor at high refresh rate. (very visible for me in FFXV in Galdin Quay during night time)
There are currently very few games that supports HDR but when it does, it can be a game changer. Check PC Game Wiki for the full list. I also feel bright colorful games benefits more in HDR compared to darker ones. Especially with the blooming of bright objects in darker backgrounds. It doesn't annoy me much and its harder to notice if you turn on 'Back Light Response' to "Gaming" in the monitor setting.
I bought this monitor with full understanding that I won't be able to fully run in 4k @ 144Hz just using my single 1080Ti. I didn't mind this much since it has Gsync. As long as my FPS doesn't dip too low, Gsync makes sure my gameplay stays smooth. I'm just waiting for NVIDIA to release the next gen GPUs that can run 4k @ 144Hz. I'm not thinking of going SLI either--been there done that. I'm tired of waiting for SLI profiles and having high temps inside my case. I'll patiently wait for a single GPU solution that will be able to fully take advantage of this monitor.
Fiddling with HDR can be a pain at times. I'm running Windows 10 Pro with the Creators' Update (version 1803, OS build 17134.137), latest firmware for my GPU and drivers. There is an option in Windows 10 to enable HDR but doing so will disable a lot of the options you can change on the Acer Predator x27 OSD. There seems to be no standard yet when enabling HDR in games. Some games will require you to enable HDR in Windows for HDR to work just like in the case of Shadow Warrior 2. In fact, even if you don't enable HDR in Windows, Shadow Warrior 2 will automatically enable it for you if you select the HDR option in-game. On other games like FFXV, I find it that enabling HDR in Windows results in black crush for me in-game. Very visible in Galdin Quay area during at night. Having HDR turned off in Windows and calibrating the monitor manually shows much better results for me in FFXV without any black crush. In Ni No Kuni 2, HDR looks very vibrant and colorful (and over saturated) but seems to work just fine on bright games like this. My problem though is when taking screenshots when HDR is enabled, the screenshots appears washed out and with hardly any color compared to what I'm seeing in-game when HDR is enabled. When I disable HDR, the screenshots in Ni No Kuni 2 looks just fine.
So yea, it would be nice if game companies comes with some kind standard when turning on HDR--where the user/gamer can just turn on the HDR switch and boom! HDR enabled with no further tweaking needed. No need to turn of/off HDR in Windows or adjust settings manually on the monitor.
Some people have complained about the fan noise at the back of the monitor and I've seen the videos of it. If that happened to me and the fan was too noisy, I would return mine too in a heart beat but that wasn't the case for me. While the fan is audible at times (only when the monitor gets hot), I don't find it annoying. It sounds to me more like white noise which goes away when the monitor cools down or is turned off. Some people that bought this monitor hasn't even heard their fan spin which leads me to believe that if your room is cool enough where you have this monitor running, you probably won't hear this fan at all. In my case, my room can run warm during the day, but at night I hardly hear it at all. I just wish Acer would have put in a dust filter for the fan at the back for this monitor and make the fan easily replaceable in case it dies. Overtime I can just imagine how much dust inside it will accumulate. The same can be said for the ASUS PG27UQ since that one has a built-in fan too inside.
Overall Review: I wish people that reviews this monitor actually owns the monitor. I'm tired of seeing people that doesn't even own or used this monitor give it a bad review mainly due to the price. They would say OLED TV is better, so and so monitor is better.. etc. If that's the case then just go and buy those products instead and stop pushing YOUR OWN OPINION to others. We are here to REVIEW this product and not read on WHAT YOU THINK. For the person that gave this monitor a 1 star because of the fan noise, I respect that more since at least he has HANDS ON experience on this monitor. If that has happened to me, I would most likely return it too and give it a bad review. But for people that hasn't even used the product and just go on and whine about the price, I feel that they are just making a fool of themselves for they are trying to review a product that they don't even own. Personally, I don't even give much credibility to the review written if I don't see the reviewer as a "Verified Owner" on the review.

Windows 10 Pro "HDR and WCG" setting is turned Off
The above settings is my current settings. Games that needs Windows 10 HDR turned on will automatically turn in on when you enable HDR in-game such as in Shadow Warrior 2 but it doesn't turn it back off after closing the game. I find it much better for overall usage to have Windows HDR turned off for now. Hopefully in the future it gets better.
There's no reason for me to have 120Hz or 144Hz setting on the monitor turned ON since most of the games I play doesn't reach that high in FPS. Have to wait till I get my hands on a single GPU that can do that and I have no problem waiting. Gsync makes the gameplay very smooth anyway for now.
I took my time fiddling with this monitor before I made my review. I was one of the first people that pre-ordered it. I received mine on June 7th and has since been extensively putting it to the the test. Don't forget to register your monitor if you decide to buy one. Acer has a separate customer service number exclusively for Acer Predator X27 owners.
Pros: The picture quality on this monitor is incredible. 4K at 27" looks very crisp and detailed and the contrast is very good beating out any other LCD I've owned. Colors are also vibrant and the out of the box calibration looked good. G-Sync works as it should giving the smoothest possible experience at any frame rates and the max refresh rate of 144Hz makes the gaming experience even better provided you have the hardware to reach frame rates that high.
HDR on this display blew me away when I first used it with vibrant colors and a very high peak brightness. Makes me wish more games on PC supported HDR. You might be wondering why I've given this monitor such a low score after speaking so highly of it. More will be explained in the "Cons" section.
Cons: After about a week of use I noticed a stuck pixel in the lower left part of the screen that was stuck on red. Even with the high pixel density of this screen it was still very noticeable even if I moved further back from the monitor. I tried for a few nights running programs to fix the stuck pixel but nothing worked. I was on the fence about sending it back until I noticed a dead pixel around the same area of the stuck pixel. After seeing this I set up an RMA with NewEgg for a replacement.
This monitor costed way too much for me to put up with pixel defects like this and I don't think anyone should should who buys this monitor. If I get a replacement that I am satisfied with I will update this review and the score but until that happens it will remain at one egg.
Overall Review: It's worth mentioning that 4K takes a lot of GPU horsepower to run games at with ultra settings. My 1080 was passable with the games I tried bringing in levels of performance that was just playable. I then bought a used 1080Ti for cheap and sold my 1080 and the 1080Ti does much better of course but to get frame rates closer to 120 or 144 you'll need much more GPU power.
Pros: -HDR on this is retina-burning amazing
-high color accuracy and richness, I have a dual monitor setup with a 23in 4k asus monitor, and the image on the other monitor looks washed out, even with the HDR turned off on the Acer monitor
-everything as advertised
Cons: -the haloing effect due to the FALD technology, which is very minor. I literally only noticed it when I was playing with the settings on f.lux and turned the brightness all the way down. I do not notice this when gaming (I primarily play destiny 2) or everyday use.
Overall Review: - everyone mentions the fan, it is not audible to me, either gaming with hdr or otherwise (you can hear it if you go directly behind the monitor and put your ear up close).
- the vesa mount came with vented slots so it does not choke the fan (I have this on a vesa mount, and even with vented slots, the fan is not audible to me)
- the RGB back light matches my build
- it is expensive, but you get what you pay for, which is fantastic image quality
- you definitely need a 1080Ti+ to fully use this monitor
- I saw this German reviewer on youtube (it is a popular video for this monitor) really criticizing this monitor, but I'm convinced that he got a bad panel because mine does not have any of his problems.
Pros: - HDR
- 144hz capable
- Quality stand
- Built in scaler works well if not pushing 4k resolution
Cons: - Lack of inputs (Typical of G-Sync)
- Rest of monitor build quality outside of the stand itself could be better for the price
Overall Review: - Arrive with no dead/stuck pixels
- Looks/runs great
- I don't hear the fan, but it's there
Pros: Think of this as a first-hand comparison between the Asus PG27UQ and Acer X27. I originally ordered the Asus version only to be disappointed after 2 separate Asus monitors had the same deal-breaking issues. The Acer version is hands down the better choice. See why below:
- 144Hz at 4K!
- HDR10 with FALD backlighting!
- The fan is unbelievably quiet. Compared to the PG27UQ, which basically was louder than anything in my office, it's near silent.
- Shrouded (optional and the Asus verson does not include this)
- Ambient RGB Lighting (aimed downward towards the desk)
- Thinner bezels than the PG27UQ
- 100 times better fan than the PG27UQ (standard PC cooling fan vs the PG27UQ has a turbine/blower style fan that is noisy as *$#@)
- Comes with VESA mounting hardware and a metal BRACKET with vented slots for the fan (vs the PG27UQ's simple standoff's that are a bit janky)
- USB Ports are on the left-hand side of the bezel (vs underneath on the PG27UQ) which are super convenient and well thought out
- Stock Stand is so much "leaner" than the Asus equivalent (although I'm using a wall mounted arm)
- Longer DP 8K Cable than the PG27UQ (I know this might seem nit-picky but these cables are $$$)
- Much nicer OSD than the older Acer models but at about equal level to the PG27UQ (same joy-stick type design on the bottom right hand side)
Cons: - Price. Both suffer from this. Wow, it costs bank to be on the edge.
- GPU power isn't quite there yet unless you're running 1080 Ti's in SLI, but as soon as the 1180+ is release I have a feeling it will be. See my PG27UQ review to see some sample frame rates.
- Suffers from the same "halo" effect in near black screen backgrounds (i.e., you can see a glow around a cursor on a black background). In my eyes this is the small price to pay for super rich blacks but it needs to be mentioned as it might bother some.
Overall Review: Background to purchasing both monitors:
I started off by purchasing the PG27UQ by Asus at release (from a competitor). I bought it and then returned it for an exchange because of horrible fan noise that sounded closer to a very intrusive coil whine. I could hear it thru my headphones at full volume - it was LOUDER than my 11 fan full tower... The noise was the same on both PG27UQ's that I owned, leading me to return them for good.
Now my previous display to the Acer X27 was the Acer X34 which I've had since release and I've had ZERO issues with it. I've also heard while some people have QC issues with Acer but the thing is that Acer's warranty support is top notch (thankfully I have no personal experience with this) and testimonials admit to easy swap-outs at the sight of any problems. Anyone that has dealt with Asus tech support knows what a nightmare it can (not always but CAN) be.
Originally I was very upset that I had to return the PG27UQ being that I'm very close to an Asus fanboy but after receiving the Acer X27, I'm glad I did - it was worth the wait. For anyone stuck between these two monitors, unless Asus revises their fan issue I would go with the Acer X27.
Pros: 1. 4K at 144 Hz even though it is 4:2:2 10-bit is simply amazing for games. I don't run this refresh at the desktop since the reduced chroma is more apparent.
2. 4K at 120 Hz 4:4:4 8-bit on the desktop makes it the best desktop monitor I've ever used. Super clear fine text, snappy mouse, low input lag precise mouse movements. Hardly anyone has a 10-bit workflow on their computer so 8-bit + FRC is not a hindrance.
3. Stand is nice and modern, looks good and does what it needs to do.
4. Games in HDR at 144 Hz 4:2:2 10-bit look just fine. No real reason to use 98 Hz 4:4:4 10-bit HDR unless your FPS won't exceed 98 FPS anyway (very likely).
5. Colors are excellent. Quantum Dot film really has made this LCD standout. Ensure SDR Colors sRGB is set to "off".
6. FALD is pretty quick to react to movement. Keep on "Gaming" setting.
7. Wide gamma range and black boost for those that like to have the advantage in a game.
8. Motion clarity is slightly better at 144 Hz over 120 Hz. Pixel transition speed may not be quite as fast as the 165 Hz 1440p IPS gaming monitors, but it is fairly good.
9. On-screen aim reticles for those that like hardcore modes.
10. HDR+G-Sync+144 Hz+4K is an amazing combination and experience.
11. DC dimming.
12. FALD in SDR. Even though the monitor allows you to turn it off; don't. The combination of IPS and direct FALD without local dimming control leads to extreme BLB and IPS glow.
13. Contrast ratio greatly improved by the FALD.
Cons: 1. Fan. I normally wouldn't care too much about the fan but it is audible. And it is always on. It even stays on for a few minutes after you turn the monitor off/standby. They really want to make sure this thing stays cool. To be determined if it is for the G-Sync chip, the FALD backlight, or both. Could effect monitor longevity if you plan to keep the display outside the warranty period. Although a fan would be easy to replace.
2. Wish there was some sort of indicator (LED color change?) to indicate when HDR was active.
3. Not a con for the monitor per say, but you will need some significant hardware to push this display. My OC'd Titan V struggles to keep up (90+ FPS) in a lot of newer titles with higher graphics settings at 4K. 4K is still very punishing and may continue to be so even when the next GPU generation comes out.
4. Auto black level in OSD doesn't appear to do anything.
5. Haloing is there. Not very noticeable in bright games but you will notice it in dark games such as horror/space shooters, menus etc. It is IPS+FALD, that's just the way it is.
6. Some GPU's won't show boot-up screens on the monitor using the DP.
7. If you use a aftermarket monitor arm, you may have to cut breather holes in the plate for the fan to breath.
8. 300 nit maximum SDR brightness. Perplexing to me considering how robust the backlight is. Most monitors these days have 350 nit minimum and gaming monitors pushing over 400 for those of us that like to play during the day in brighter rooms.
9. Even though it would be extremely hard to run at 4K, no ULMB. I feel this has been a wasted opportunity of the FALD backlight.
Overall Review: Neutral:
1. 4K at 27", very good clarity. It is a neutral point for me and not a pro since I would have preferred 32".
2. AR film. It is much better than what they put on TN panels these days, but still short of my preferred semi-gloss.
3. Build quality. Not the best or worst I've seen. Joystick control on the back feels a bit flimsy.
4. Mediocre 4K Blu-Ray playback via the HDMI 2.0 input.
5. Light sensor on top of monitor. Auto brightness is not adjustable if turned on. A bit too dim for my liking when enabled.
Overall for desktop use and bright games/first person shooters like PUBG and the Battlefield series, there is nothing that can hold a candle to the X27. Including a 2018 OLED. The amazing clarity, colors, high variable refresh rate plus HDR makes it a real treat. There are some significant drawbacks, most notably blooming and the fan, but if you want the best gaming monitor on the market, look no further.
Pros: General Pros
This being my first 4k monitor I am going to have to say I am pretty impressed with the display and color.
- The 800-1000 nits is pretty unreal and can make you want to blink or look away if you watching a movie in a dark room.
- HDR and the adobe color for UHD movies and games is amazing!
- G-sync (which i have had on my old monitor is for sure a must have with games)
- Inputs options are good. An extra DP would be nice though.
- I was a bit worried 27" was going to be too small, but it works out just fine. Ideally i think a slightly larger panel at 4k would be optimal, but having before this 2 x 2k monitors at 27". If you scale up to 1.5 or 150% you basically have the same amount of real-estate as a 2k it seems on this display. So I typically run it at like 1.25 / 125% so that it's not to small, but you get more space when I am doing professional work on my Linux machine.
Cons: Black screen
- The screen in some games flickers black for a second. ex) overwatch command menu causes screen to go black. This is over DP. I have tried 3 different kinds of cables and also tried 2 different HDMI cables. I wonder if it is the connector on the monitor or if there is a software issue related to the NVIDA or Win10 drivers. I have found a few reports of HDR issues as well as other things. Keep in mind this flicker ONLY happens in game and with HDR turned on in certain situations.
Fan Design (*Hot topic*) no pun intended ;)
- The fan's cool air intake area is obstructed by the default desk stand and *extremely* obstructed by the wall mount bracket. I am surprised no one else has mentioned that the default stand also causes issues. It's a big design flaw if you ask me. The fan's cool air intake is positioned right in the middle where all the mounts come together.
- My recommendation is to mod the mount if you are putting it on a non-stock monitor mounting system to increase the cool air intake.
- I also would highly recommend ditching all 3 plastic covers on the back. 2 of them obstruct the fan cool air intake and the 3rd seemed to help when gone. If your desk is against a wall no one will look back there and the noise reduction; IMO is worth opening it up for increased air flow.
- Basically from what i can tell the air comes in through the mounting area and hot air is then forced out through vents on the top and bottom of the monitor.
- Not being crazy technical when it comes to sound. I used an app on my phone to measure audio sound produced by the monitor.
-- I was getting about 38 dB (quiet library, bird calls) after removing all the snap in plastic covers and playing a movie in HDR without the movie sound off obviously. (the best i have gotten so far)
-- With the plastic cover parts on I was getting 46-51 dB (quiet office, moderate rainfall)
-- For comparison I was getting about 30/34 dB from my beQuiet 900 case with a evga 1080ti, nzxt water cooler.
-- My huge addict fan also for reference was making like 65 dB and i would consider that loud as F***. Lawn mower 90 dB and vacuum cleaner is 70 db
Overall Review: Apparently i can't reference compeditors like the Company that delivers packages in 2 days for free and you get subscriptions to for Prime. *subbing the company name out for A-Prime*
If you plan to use it for UHD online streaming content. Get ready for some headaches just as a FYI. I have spent time with both Netflix and A-Prime support. A-Prime being the WORST and not resolving my issue at all and wasting 35 minutes of my time. It was really bad like when I was 12 and bored writing a program on C++ to respond to questions i ask it. The representative was reading a script and taking 2-7 minutes to respond between answers and didn't know their own policy and sent me links that 500.
To the point..... There are a lot of requirements to get UHD to work with online streaming on a PC. The biggest thing i learned is when the sniff your hardware to determine if you meet their silly DRM requirements. You must be using Microsoft Edge and buy an app that handles the codecs for 4k DRM requirements. You must also be using the HDMI port and you can't have dual monitors turned on. (maybe if both monitors are 4k it might work)
It seems to be so far much simpler to just by a A-Prime Fire stick (newer version that supports 4k) or the Chrome Ultra and plug it in through a supported HDMI KVM or straight into the monitor. Keep in mind audio then becomes fun to sort out if you plug it straight into the monitor. The built in speakers kind of suck, but what monitor has good speakers and who in their right mind would get a display like this and depend on them? Keep in mind there is a head phone jack. So I am going to try working out a HDMI switch soon So i can connect things up efficiently. Keep also in mind you can sync the firestick to things via Bluetooth. Not sure how well that would work with a sound bar or head set yet. Experimenting now with the A-Prime Fire stick soon as well.
I really enjoy the performance I get out of it and I am sorry for listing more of the Cons than Pros. I figure it's more helpful to hear the errks than the ooowws.
Regardless of the two main issues I see with it is the
1) over inflated price tag (Minus 1 egg)
2) the fan design (loud, but without the plastic covers on the back its better.) ( Minus 1-2 eggs)
If the only thing wrong was the price I would rate it 4 eggs, but it's not and I think i am being generous for the price and obvious design issues giving it 3. The reason i don't put it at 2 eggs is because there are tons of pros baked into this and if you have money and are okay with doing things to reduce the fan from ramping up then it's a sick monitor.
Some things I am going to test soon. I typically keep my house at 76 F, which tends to be hot for people i know. I have a been keeping a themonitor between the base stand and the front of the display. Under the monitor and it typically reads around 80F. It basically gets hit by one of the exhaust vents on the bottom. I have noticed when the afternoon sun hits my office and i forget to turn up the AC to compensate it can get as hot as 88F under the monitor. Which is when I start to really notice the fan ramping up. So I am going to run a cooler environmental temperature in the office and with out the components see what kind of dB i get.
Pros: Works as advertised 4K @ 144hz with HDR and Gsync.
Solid Build Quality
The colors blow away my 4k TV I paid $1500 for about 2-3 years ago.
No Backlight Bleed
OSD Navigation is fine.
Response Times are great!
My PS4 runs at 2160p with HDR :D
Cons: I had some issues with screen flickering black and dropping signal my ps4 pro but solved it with turning of HDCP off.
FALD lighting causes a halo when looking at black screens around your cursor. Nothing that ACER/ASUS can fix and its not that bad.
Text Scaling in some older games like GMOD are hard to read in 4k but that comes with the territory of 4k nobody was playing 4k games when source engine was made.
Cost. But lets be honest they charged $1200 USD for the Dell 4k 60hz Panel.
Overall Review: Some guy is trashing ACER QC because he had a bad fan. Not saying it what happened because obviously there is no way for me to know. But it could be on Acer rushing out units or it could be from FEDEX ground shipping. Either way he was entitled to a replacement or refund. Not every panel will be perfect or made identical. AU Optronics makes the panel and the Acer/Asus house the panel. So never really blame bad panels on them its more of issues with power or guts of the monitor. We live in a world of mass production in every industry nothing will ever be 100% perfect.
