    Apparently PG35VQ Issue has been fixed and Firmware update is coming. I wasnt told if new units from november will have this firmware or which serial numbers will be affected.
    Dude.
    It is Asus PG27UQ that got the firmware upgrade but people need to send the monitor back to the RMA service because only an authorized service can do it and has the right equipment for it, I hope it will be similar with PG35VQ and x35.

    Didn't Asus claim they release a tool that allows users to do a firmware upgrade by themselfes? Also that thing is out for over a year now, does it take them that long for releasing an update? That would be bad news for the x35/pg35vq as they are inherently different from the PG27UQ as far as I know.

    Show me this tool? because I can't see it anywhere and if Asus pg 27uq got a firmware upgrade then pg35vq will also get it sooner or later.

    I don't know, they just said they would release one as I mentioned: https://www.asus.com/support/FAQ/1036750#

    There is says

    "Or you can wait until later this year when a downloadable utility tool will be available to update your monitor’s firmware yourself."

    But I cannot find any more info than this.

    Why are you guys going on about a whole different monitor in this thread linking sources yourself to irrelavent information? :/ as funny as it to see it makes no sense.

    I think Ive seen the hopefully true source.

    Asus are saying they have found the root of the issue and will bring out firmware update end of 2019. -source is a direct communication to a user on twitter.

    Manny,
    Will Acer be able to do the same thing seeing as its the same panel and issue?

    I would send my monitor in straight away if I knew the issue had been found and would be fixed...

    Quick update,

    Can you see any flicker? apart from it going brighter or less brighter with my camera.

    OK my little review on this screen:

    The flickering on my one is no issue at all. Really not. Same goes for the fan noise. I can hear it next to my silent PC. Im sure I will return the screen anyways because what really bothers me are the very weak response times in dark/grey areas. It may be good for a VA panel but comming from an excellent and fast IPS panel that really bugs me out. Its even annoying for me in non multiplayer games.
    The HDR experience is really amazing. Playing on widescreen is amazing also. The screen itself looks very cool. I would love to keep it but it seems that those low response times in grey and black areas are killing it for me. When the screen displays a rather white image with a light background everything is fine but you do notice the low response times in all games which have a rather dark background: for example when its night time in a role play or when there is a lot of shade etc. you get what im saying.

    But considering the very high price it is not worth it for me. If that screen was an IPS panel it would be a dream. Also I have to mention..even though the fan is no problem for me, of course I can hear it a little bit. I dont know what will happen in 2 or 3 years when the fan is kinda dusty and Im scared it will be louder then, since we cannot open the case an clean it or even change the fan when it breaks.

    TLDR: for me personally UNFORTUNATELY too many negatives to actually keep the monitor for that money.  Again: the flickering on my sample is very very low!

    It really gives a hard time to decide whether to keep it or not. On the one hand its really amazing to game on with hdr, widescreen, good responses in light scenes but on the other hand you have the slow response times in dark/grey areas which I can notice in every game I tried.

    Does anybody know if there is something similar planed in the future without being a VA panel?

    Would you like to share the source with us? I can't find it.

    anyone see any flickering on this?
  • BoatkettlecheeseBoatkettlecheese Member Posts: 47 Devotee
    Most cameras only record at 30hz which isnt really an ideal rate to showcase something that happens at 80hz+ even so you can see from other peoples on here that its the case.

    The thing is why should I send the monitor in 40 pounds per pop 4 times to get a monitor that works as advertised? :/ does that sound remotely fair?

    what you show in that video, some people call "flickering". it does work as intended. If you use it @200Hz, the blacks are always 9 frames behind all the rest of the brighter colors. The black-to-grey transition times fit only in the 23Hz frame time.
    The more you increase the refresh rate above 23Hz, the more black smearing and ghosting you will have.
    This is not a high refresh rate panel. Not for dynamic content at least.
    This monitor makes sense only if you use it to watch 30fps movies or for static content like a very expensive digital picture frame.

    Hi Boatkettlecheese,

    Unfortunately, I can't confirm and don't have access to any other information that is not from Acer. From our end, we are still waiting on a response to provide you with updates on this matter.

    Thanks you,
    Acer-Manny

    the guys from TFTcentral provide a very well made review of the PG35VQ, witch is the same monitor.

    Seems like the black pixels must be driven by a different, more aggressive overdrive pulse than the bright pixels. And that requires a lot of extra processing.
    It would have been easier to stick with IPS like the PG27 or X27

    So I ended up getting my X35 monitor the other day and made several videos to see if I can reproduce the game flickering:










    The only thing I can reproduce is the snow image. My games appear to be fine and I tested on several different settings
  • KaiserlolKaiserlol Member Posts: 15 Troubleshooter
    Celith, there is no visible flickering visible for me but yet the slow response times in those black areas remain. Hal_9000 explained it perfectly.

    I returned my monitor today for the exact same reason. Im disapointed to say the least.

    Yesh I knew that was a trade off from going from my XB271HU monitor to this monitor. However; still using both monitors right now I actually prefer the ultrawide because the contrast is so good.

    So let me get all this correct before I decide or not to return my monitor.

    "Scanline issue" (snow village):
    Can potentially be fixed by firmware update.

    "flicker issue" (Black draw latency):
    Simply how VA works and a limitation of the technology that cannot be fixed

    Any other issue I am missing?
  • KaiserlolKaiserlol Member Posts: 15 Troubleshooter
    The slow response times will stay as well if you consider that as issue.

    Finally ended up getting my X35 the other day and had a chance to test the monitor for the flickering issues in game as well as some images. The videos I recorded are done with the monitor set to the calibration from https://pcmonitors.info/reviews/acer-x35/. I left overdrive on normal and used HDR on during my tests *422 and 444*. however; during testing HDR shows as on when in RGB color format but was not on so that might be a bug. G-sync and HDR did not impact image in games at all to cause flickering so I skipped making a bunch more videos to save on time. I left overdrive on normal since off and extreme causes noticeable overshoot. With some videos out there showing the flicker in games I decided I would try to make my own videos showing the monitor I have compared to the other videos. I do not have gears 5 or Resident Evil so I am not able to make videos for those games.

    Overall in my testing so far it seems like my games are not having the flickering issue that others are showing in their videos. However; After changing the size of the village image I ended up getting the flicker that does go away if overdrive is turned off. I am going to continue doing testing when I have time. If anyone else has any suggestions after reading this post I would be more then happy to answer questions and try for additional videos.

    I don't mean to double post but I have no idea why the post above me is now clearing when it was not working the other day.
