Review on ViewSonic VP3268A 4K Ergonomic DisplayPort Professional Monitor, 3840X2160P Resolution, Cable Lock Slot, Anti-Glare, 3H Surface Hardness, On-Screen Display (OSD), ‎VP3268A-4K, HDMI, HD, 4K by Todd Rodriguez

VP2768a-4K is said to be flicker-free. I bought two monitors in January 2022. It's September 2022 and ONE of them just started acting while watching a video. First, the static background in the video was animated. Then the color turned completely yellow. Then there was the shadow of closed windows. Restarting the computer fixed THOSE issues, but now it flickers horribly even with no windows showing on the display. Flicker is particularly noticeable when viewing from the side. Turning the monitor on and off and changing the refresh rate will not affect the flicker. It just doesn't stop. VERY disappointed and now I have a headache.
