    I have recently purchased this monitor and I’m having an issue with it and was wondering if any other owners are having a similar problem? It’s a difficult problem to describe as I’ve never seen it before, almost like the image from one windowed program (or any image in general) carries on across the entire screen (see picture). It’s most obvious where windowed programs start and end and with white sections in the image (such as the address bar).

    I’ve been in contact with AOC and have tried multiple different cables and on a separate PC with a different graphics card and the issue persists. It is most obvious at 144Hz and less so at 60Hz (although still clearly visible). AOC are suggesting that the firmware on the monitor needs updating.

    I really like the size and spec of this monitor and I have been unable to find any one else reporting such an issue so I’m not very confident about it being a firmware issue. If any other owners of this monitor have any input it would be much appreciated.

    Many thanks.


    I can confirm that this issue has been observed by at least one other user (who has not posted here) and also observed on the Samsung C32HG70 which uses the same panel. It is a form of inversion artifact and something I’ve seen on various monitors in the past, although I did not specifically observe it on the AG322QCX. It is related to voltage regulation and typically related to the panel itself (certainly seems to be the case here) rather than anything to do with monitor firmware. So it’s unlikely that AOC would be able to put out a firmware fix that would stop this happening, although not impossible.

    So yes, it’s normal. Try not to let it bother you and just enjoy the monitor. Obviously if it’s interferring with your work or something then that’s another issue, but I believe you were posting just to make sure it wasn’t a fault with your specific unit; and it isn’t.


    Thank you for the reply.

    Yes, I was just trying to see if this was specific to my panel. I try to keep my work off this PC but still end up doing some in CorelDraw (which is where I noticed it) and it’s pretty distracting for me unfortunately. The 32″ samsung that you mentioned was an alternative I was looking at but I guess I’ll have to think again on that.

    Many thanks.


    All right, I guess I could write down some of my thoughts after using the monitor for a month now.

    Let’s cover the good things first. The size is one of the main reasons I love this monitor. Coming from a 17” 1080p 100Hz laptop monitor the experience was breathtaking. Additional space allows me to multitask way more comfortably and coupled with vivid colors and deep blacks, games are way more immersive. Even simple games such as Minecraft are elevated to completely another level. Monitor is curved just right, not too much but enough that when you walk into the room the monitor immediately catches your eye. The anti-glare coating is also perfect, it manages to disperse all but the most intense of reflections, but it does not cause any graininess whatsoever (my laptop does that and it can be very distracting/unpleasant). As one user here already mentioned, the monitor is perfect for watching high bitrate YouTube videos (I personally like to set the resolution to at least 4K).

    Now for some cons. The colors out of the box for this model are all over the place, especially the red. Luckily this can be fixed easily with 3 color sliders in OSD menu. Also the monitor’s gamma is a bit low by default, probably to combat some black crush that tends to happen at 3-5 darkest hues. That I fixed in Nvidia’s control panel. In the end, I set color sliders to 35, 45, 50 for red, green and blue, respectively, and gamma in Nvidia’s control panel to 0,93, 0,95 and 0,95 for red, green and blue channels, while leaving monitor set to gamma setting 1. For reference I used my Oneplus 3 in sRGB mode, as that’s the closest reference to sRGB calibrated monitor I have. The viewing angles are also a bit sub par. They don’t skew colors as TN panels do, only black gets lighter when the view is not centered properly. That and the curve make the monitor not ideal for viewing movies in groups. Also the OSD is a bit clumsy to use and finding the correct setting can be a chore.

    As a final note, I’d like to say that I used the monitor at 130Hz via DisplayPort and occasionally at 85Hz via HDMI (at native resolution) as my 5yo laptop’s 660M has problems running the monitor at it’s full 144Hz. I plan to switch to full refresh rate as soon as I get a new computer and also test the variable refresh rate function if I get an AMD card. But even so, I highly recommend the monitor and would by it again, if I so needed.


    Thanks for sharing your detailed feedback, hackguy. That is exactly the kind of thing I was hoping to see in this thread and will be a very useful read for our readers. 🙂

    I’m also glad to hear that you are pleased with the monitor and would recommend it to others, more so now that you’ve corrected the ‘out of the box’ imperfections with gamma and colour balance. It’s nice that you can look forward to unlocking a bit more performance from the monitor once you get a new system, too. Something to look forward to.


    thanks for the update on the Philips. I can wait a month or so to see what developments there are, with the AOC in standby as needs be!


    Hello Guys,

    i have 10 days the monitor and i have notice some issues. There are some gray lines vertical to the screen. I test it with displayport and hdmi cable.Same issue. Do i have to send it back for refund?



    If the bands are as visible as in the photohraph or more so, then yes you should return the monitor.


    FINALLY i have found a Forum where i can talk with other Owners of this Monitor!
    I HAVE ONE Problem with Displayport and it dont happens all the time but really often:

    When i send my System (Win 7) to Standby everything going to sleep.
    After a while i want to wake up the System, my PC booting but my Monitor says: DP No Signal!
    Only thing i can do is to Hold the Powerbutton of PC and power off the system.
    After i power it on the Monitor gets the Signal =/
    Its not always but in 7 out of 10 times it happen.
    THIS was the Reason why i changed from ASUS VG248QE because i thought its a Monitor related problem!
    Now same happens with the brand new monitor =/
    So does this mean i need a new cable or is it a Graphiccard problem?
    EVGA GTX 1080 (1 year old) by the way.
    Any suggestions?


    It look’s like your GPU not waking up, try to press “windows key” + “P” and hit enter


    It may be caused by the fact the monitor goes into a state called ‘deep sleep’. Some models have an option to disable ‘deep sleep’, this one does not. So I’m afraid you have to put up with this behaviour. You may have better luck using HDMI 2.0, although technically that too has ‘deep sleep’ so you may simply encounter the same issue. It tends to be a bit more forgiving, so it’s worth a try.


    do you think AOC could make a new firmware to fix that ?
    Or can I reach 144hz and 2560×1440 with HDMI2.0?
    if so then it wouldn’t be a problem for me to change that.
    My DP cable is a LindyCromo from Amazon.
    Now I bought a new one StarTech VESA certified maybe that’ll help.
    I found a lot of websites talking about displayport issues on every monitor+gpu combinations.

    thanks for answers by the way!


    Yes, as noted in the review HDMI 2.0 supports 144Hz at the native resolution –


    thank you sir!
    Found it in your review 🙂
    I’ll test it with the new DP-Cable if it won’t be better I’ll try it with a new HDMI 2.0.
    If it won’t help either I will ask AOC if it’s possible to deactivate deep sleep with a firmware fix.
    on the old monitor it only happend with Displayport.


    So strange,
    i let my pc in standby over night just to see if i can reproduce it.
    Strangely today it worked without any issues, as i woke up my system the monitor immediately went on.

    @ PCM2 a Question to the Monitor:
    Did u used it under Windows 10 64bit?
    Because my monitor dont work on Windows 10, for example:
    When i start steam the Monitor goes off and On for 2 seconds.
    When i start a Game the monitor goes off and on every 2-3 seconds as long as the Game is running in the background.
    If i can stop it via taskmanager the monitor is working normally.
    Is this a driver issues maybe? I updated my Windows 10 and NVIDIA Driver yesterday and it still happend.
    Now i switched back to windows 7 64bit and the Monitor is working in every situation (Just that one Standby thing issue was there/is there).
