Pros: Let's clear up some facts:
The B286HK supports 60 Hz. Using the provided DP 1.2 cable I've run 4K @ 60Hz on both an NVIDIA GTX 680, 750Ti and Intel Haswell 4600 IGP.
Video looks delicious on this panel. No ghosting and plenty of contrast.
One of the detailed reviews on the web points out that in this class of panel and among their tested monitors, only the Acer and ASUS TN monitors properly display grays and have very low (10.9 ms.) measured input latency (display lag).
The USB 3.0 hub is a worth getting since it reduces desk clutter.
Lots of inputs: DP, miniDP, DVI, HDMI.
The panel is VESA compatible.
The Acer's OSD display is easy to use and, as noted in a web review, offers a level of fine-tuning not found in other TN 4K monitors.
One of my favorite features: *no power brick*. The power supply is inside the monitor and you can use a standard PC power cable.
I'm upgrading from a 3-monitor almost 9 yr. old 5440x1200 battlestation and am enjoying the simpler configuration and cleaner desktop.
Side note for OS X users: I got a chance to see one in a store connected to a Mac Pro. OS X looks glorious on a 4K 28" LCD as the OS seems to get the scaling right.
Cons: The cons were called out in web reviews and are expected:
• wobbly stand -- use another VESA monitor base if you have one.
• anemic speakers -- expect to use external speakers
• the TN viewing angle peculiarities can be seen from off-angles but it's not a big deal -- it's only pronounced from above. Go see a 4K TN panel in the store if you think you'll care about this artifact.
• accidentally powering cycling the monitor while running seems to result in a handshake that identifies the monitor as smaller than 4K before properly identifying it as 4K. The result on Windows 7 is that you might see an icon-rich desktop and open apps moved or rearranged. Googling reveals this might be a common problem across a lot of 4K monitors. It's unclear if it's a driver, OS or monitor firmware issue. Rest assured, this does not happen if the monitor or PC goes in and out of sleep mode -- it's only a power cycling while connected issue.
Overall Review: 28" is a reasonable size. Some people (like devs) might want an even larger monitor or a curved panel to really benefit from the available pixels. But 28" 4K is a useful jump from a 2k x 1k monitor setup.
I don't see how anyone can complain about this piece of tech when it's priced so low. It's an amazing value and a very tuned panel.
Pros: I got this monitor on sale, and for the price I paid, it's a steal. I upgraded from a 21.5" 1080p monitor, and the size, resolution, and DPI on this monitor, comparatively, are fantastic. It was worth every penny to me for those reasons alone. I do a lot of programming, and It's nice having the option to tile windows across 28" of space.
Cons: There's one stuck pixel in the top left quadrant of the screen. It's only noticeable when the monitor is black, and it's so small that when the monitor is in use it's not visible at all. It actually took me about a week to notice.
There's a huge problem with ghosting, especially with darker content, though you can see a trail even behind the cursor when you move it, if you look closely. It's something I really didn't like at first, but I've grown to care less.
The speakers are garbage, but I didn't expect anything different.
Lastly, I'm still not sure what's causing this, it could be entirely unrelated to the monitor, but every once in a while the screen blanks for ~5 seconds, then comes back. I just added another video card, and I have a tendency of running bleeding edge software, so again, it could be entirely unrelated to the monitor. I'm just not sure yet.
Overall Review: Most OSes have trouble doing DPI scaling properly, especially on HiDi displays. Expect text and UI elements to look funky sometimes. That's the price of being an early adopter.
If not for the ghosting and stuck pixel, I would rate this monitor 5 eggs without hesitation.
Pros: - Fantastic crisp graphics that 4K detail provides
- Colors and contrast are decent for a TN display
- Looks good on your desk with a relatively thin bezel
- Tilts, swivels, and has all the basic connections, including USB 3.0 ports
- The display runs fine at 60hz with DisplayPort, unlike what was reporting in a review earlier here.
Cons: - One stuck pixel (it happens)
- TN panel with limited viewing angles and color fidelity (though not bad by any means)
- There is a huge ghosting issue with all graphics. Moving around the screen causes edges to darken and drag subtly. This is NOT a 60hz low framerate issue. Might be an OverDrive problem.
Overall Review: Stand is a bit weak. Be sure it screws in properly!
Pros: * 3-year warranty
* Excellent build quality, no creaky plastic or scratch-prone gloss materials anywhere
* Great response times
* Incredible viewing angles in landscape orientation
* Unreal price (bought for $348 in late 2014)
* Every display connection under the sun available, plus a USB 3.0 hub
Cons: * Cannot hard-set the input and make it not auto-search. So on occasion, if I'm switching between my TV and this display, I have to wait for the monitor to cycle through all inputs until it finally reaches the Mini-DP connection from my PC.
* Very noticeable ghosting against certain colors (mouse cursor against greys, for example)
* When rotating into portrait mode, the "rainbow effect" and distorted colors are unbearable. But it's a TN panel after all, so not totally unexpected here.
* Some backlight bleed on the edges, but unnoticeable unless you've got some black color on the screen. Again-- TN panel, what can I say?
Overall Review: Incredible monitor, especially for the price, but still a TN panel with its usual caveats at the end of the day.
Pros: Bought this monitor during the black November deal last year for $399 and have been pleased with it since.
Cons: Ghosting is pretty noticeable on this monitor but not horrible. Depending what game your playing you will see it. Switching between inputs can be very slow.
Overall Review: In order get 60hz 4k you need a good graphics card with display port 1.2, I've used this monitor on 2 systems one with a single Radeon 7970 and 2 780ti's in SLI Both worked well.
Pros: Sharp picture
rotates horizontally and vertically
rises up and down
stable - shaking the table doesn't induce bounce or wobble in the montior
Clear and easy to use controls
each key's function appears on the screen immediately above the key :-)
Good color temperature settings.
Contrast and brightness adjust well.
The smallest text is crisp and readable.
Colors all look great to me
It came with every conceivable cable *HDMI, Display Port, USB 3.0 A to B, power, dual male audio
Cons: Power light is too bright for me (but I'm VERY picky about that, nearly every blue LED in the house is covered with tape or black Sharpied).
Speakers are tinny sounding. Not bad, but definitely not for music.
When used at 1920x1080, a little blurrier than I would have expected.
Overall Review: Caveat Emptor - I'm a programmer. I use this for text on a black background and for a browser. I don't watch movies or play games on it.
I love my new 4K monitor, but I bought 2 and only use 1 right now.
Regarding 4K monitors in general:
DO YOUR RESEARCH before buying two.
I bought two of these.
I have a Macbook Pro Retina that will drive 3 external monitors.
It will NOT drive two 4K monitors. Only 1.
Mine is from 2014. The 2015 model will drive 2 of them.
Most notebooks from before 2015 will not support 4K.
Many new notebooks will not support 4K.
Nvidia cards below 650 will not drive a 4K monitor.
Most NVidia cards will only drive 1 4K monitor.
The cheapest card I found that will drive one is the AMD Radeon R7 240.
I haven't found a single card that says it will drive 2 4K monitors (I'm sure they are out there, but I've not found them.
I still love this monitor. One of these 28" 4K monitors is way way better than the 2 22" HD monitors I had.
Pros: The picture is amazing once the computer/software are set up correctly. The primary purpose that I purchased this monitor is for graphics design using various mainstream platforms. It does a great job! Colors are true and as printed. A great step up from 1080p.
Cons: The input refresh is annoying. Every time the monitor/computer is turned on or comes out of sleep mode the monitor has to scroll through the multiple inputs. Since there are four inputs and I happen to have used the last one, Display Port, I have to wait about 20 seconds for the monitor to check the other three before allowing me to use the display.
Overall Review: Ever since I connected this monitor to my computer, the monitor has failed to come out of sleep mode several times a week. I did not have this problem with my last monitor and it has become quite annoying. I do not know if this is a video card issue with a 4K monitor but the only way to get the monitor back is to hard reset the computer. All drivers are up to date and my video card,
EVGA GeForce GTX650Ti Boost 2GB GDDR5, can handle the monitor. I built my computer at the end of 2013 and this is the first interface issue I have had.
Pros: Great design. Great value.
Cons: Well, this is a value panel, although it would be hard to tell for most use. I wouldn't expect it to be ideal for precision graphics work.
Oh, and the speakers are garbage but who cares really?
