  • So what I believe you are describing is polarity inversion not overdrive. TN, IPS, VA panels all can all maintain a pixel's brightness between frames. Voltage changing from positive to negative is polarity inversion and it is a way to keep the panel from damaging itself. There is no need to do this otherwise. A think…

  • Actually this might be the issue: From Nvidia's webpage "G-SYNC’s variable overdrive eliminates ghosting artifacts by predicting the next frame and adjusting the parameters of the LCD overdrive." Does anyone know anything about this or how it works? I am thinking that maybe the flickering is a dual-issue: 1. The VA panel…
  • As to why I believe that this issue is fixable by a firmware update: 1. The flickering issue inexplicitly disappears when the OSD is active. 2. There is a precedent for flicker being fixed in VA monitors: https://www.reddit.com/r/ultrawidemasterrace/comments/6d0fmj/aoc_agon_ag352ucg_flicker_issuefixed_thanks_nvidia/

  • OSD OFF ABOVE OSD ON ABOVE "scan lines" are removed
  • Maybe I am missing something, but how would overdrive cause scanlines on a static image? On certain spreadsheets, I get uniform vertical RGB scanlines across the entire monitor. I don't see how this would be caused by overdrive since the pixels are not changing.
  • Come on Acer... Are you planning to just leave this thread to die? Is that what the higherups told you to do? Even a "Yea we understand this is an issue, but we already have your money soooo.... we're not going to do anything" would be better than your current state of communication.
  • Ok, so this is a very easy way for me to reproduce the flickering and the lines that appear. It is so easy that I'm worried that the problem is getting worse because I think I would have noticed this before. When the monitor is connected to an output that is not producing a signal and you turn on the osd this appears. Can…
  • @Acer-Manny Assuming that this issue is not fixed what is the return policy? I would prefer not having to return this monitor just to buy it again if the flickering is resolved. Will there be an extended window to trade-in this monitor for either cash or a replacement?
  • Also as a side note, how much does Acer expect the consumer to pay for a working product? $4000, $6000? I kind of assumed that basic qc would be included with a 3k price tag.
  • I'm getting worried by the lack of customer support response. Can you atleast confirm that a group is working on fixing a problem that appears to affect every panel of your flagship product?
  • Well, I thought I was immune, but I am having the same issue. I hope a solution is being devised, if not...
