My Acer XV340ckp is randomly
blinking/flickering. Every so often the screen 'blinks' and there is a quick
flash of a stripe running horizontally across the screen approximately three
inches from the top of the screen. This could happen every few minutes to once
every 20 mins or so. There is no noticeable pattern to the frequency of it
Occasionally the screen also seems to go dark for a second. As if
the brightness has been turned almost all the way down momentarily. This seems
to be rarer and maybe happens once a day.
I am currently running the screen at
144hz on a windows 10 machine powered by an i7700k and a 3080 gpu. So far I
have attempted to solve the issue by trying an alternate display port cable and alternate display port port; uninstalling all my display drivers and reinstalling them; ensuring I
have the latest display driver from the Acer site and the latest 3080 drivers.
I have noticed the issue does not seem to occur when the screen refresh rate is
60hz or lower. I have also noticed it most frequently happens when I am
browsing the internet and have youtube in one window and a normal text/image
based website in another. However I can play modern pc games at a high refresh
rate without issue. I have also tried tweaking some of the settings in the OSD.
i.e. overdrive on/off, gamma, contrast etc without success.
I plan to try the screen on an entirely different machine within the next day or two. After that I am out of ideas. I would be grateful if anyone could give me any suggestions as to how to stop the flickering.
