Flickering out of the box 9/19/2019 10:56:47 PM

Pros: Upgrading from a 1080p 16:10 LCD (1920x1200px in 23in, so it had excellent picture quality). The picture quality on this one far exceeds my prior monitor (that's 4k for ya), and being able to run 4k at high refresh rates is very nice.

Cons: Out of the box, the monitor would loose signal past 82hz (complete black screen). Spent two solid days troubleshooting this (tried calling technical support and found out that if you've got even a basic knowledge of computers this is a complete waste of time; don't bother, you'll just spend hours relaying information about what you've already tried). Ended up 'shotgunning' parts, and it turns out the displayport cable it came with was faulty (I'd actually tried to check this first, but the spare cable I had on hand was only dp 1.2, and you need displayport 1.4 to run high refresh rates at 4k resolutions). My only other complaints so far are that the onscreen display selector on the back of the monitor is fiddly and hard to use, and the frankly abysmal quality of the built in speakers (they're awful). On the whole, it's a good monitor, but I'd wait for it to go on sale, as its list price is excessive for what you get.

Avoid 9/19/2019 4:09:04 PM

Cons: I wrote a lengthy review explaining many problems with this monitor, but it never posted. I'm not rewriting the whole thing.
Flickering. It's unacceptable from a monitor of this price.
HDR is trash. It's too dim to use. Flickering is worse when HDR is enabled.
It randomly loses signal and goes black. The only way to get signal back is to change input to HDMI then back to DP. It happens several times a day. Sometimes several times in an hour. Unacceptable.

Overall Review: Don't buy Acer. I bought this one to replace a 2k Acer monitor that is absolute flickering trash. This one is trash too.

My first 4K experience 8/17/2019 2:42:32 PM

Pros: Looks beautiful. Awesome color. A factory calibration sheet was included in the box.

Underside lighting shows red if sync'd and white if not. That's a pretty neat feature. You can change this to just a static color if you want.

Cons: None yet.

Overall Review: This is my introduction to 4K and I love it!

A little over priced 7/6/2019 4:00:41 AM

Pros: -Great color accuracy
-High refresh rate

Cons: -No real 144hz support (requires chroma sub sampling, which ruins picture quality)
-It has a fan and it is audible
-VESA mounting bracket results in monitor sitting lower than normal
-HDR400 is a joke and even then enabling it means using either 98Hz refresh rate or more chroma sub sampling

Overall Review: If this were available for 750-800 then it'd be a good value, as it stands its sorta over priced. I cant stress enough that the VESA mounting bracket makes this an awkward companion for a monitor arm. At my monitor arm's maximum height this thing sits 8 inches from the desk.

Waiting on repairs 6/17/2019 11:03:34 AM

Pros: Beautiful picture
Gsync is Amazing
HDR is nice

Cons: Flickering just over a month after purchase, still waiting on repairs

Overall Review: The monitor was great for me for the first month I had it. Just over a month into it's life it started flickering, most noticeable when mousing over items in a web browser. This only happened over display port, not over HDMI. I sent the monitor in and it was received on 5/30. It is now 6/17 and there is no ETA for when the repairs will be complete. For the money I spent on this monitor I would expect better customer service. Hoping this gets resolved soon.

Best 4K G-Sync monitor with 144Hz for the price 5/23/2019 7:05:44 PM

Pros: For the price this remains the best 4K G-Sync monitor with sharp professional level colors and amazing gaming performance with the 144Hz IPS with 4ms response. Matched it with the RTX 2080 Ti and getting 120 fps without a hitch. No G-Sync issues.

Cons: Stand legs are a bit long and may be a bit of hindrance.

HDR 400 joke. UDE old Samsung 370 nits. 5/8/2019 4:29:32 PM

Pros: -4k is amazing compared to 1080p especially in open world games

Cons: -HDR 400 is a joke. I have the old Samsung UDE series 4k 60hz monitor and the peak brightness is just as high as this one and it's not HDR.

Overall Review: -If you want true HDR you need to get a monitor or TV that supports 800 nits of brightness. That is true HDR brightness.
