Hi I recently bought third monitor with IPS matrix (nec multisync ea244wmi) and have some annoying effects especially visible on dark/gray colors.
I mean I see like wave of falling pixels Just like screen wasn't updated enough often.
I dont see this effect on rest of monitors but they arent ips.
My GPU is RTX 2060.
Its connected with display port, I checked cables and tried changing to HDMI, tried also changing contrast or brightness but still got this effect.
Maybe this video will show you what I mean, left monitor doesnt have this effect, im Talking about right, both have 59Hz:
