I bought Asus VG249QL3A monitor (1080p, 180hz, IPS). However I'm experiencing a major problem with it:

When the monitor is working at 60Hz, I see vertical lines when there are moving objects (such as the rotating Nvidia logo on Nvidia control panel), or when my eyes move from one spot of the screen to another. When the refresh rate is raised to 180, the lines disappear. However, some games I play support only up to 60 FPS and the monitor has to tune down to 60Hz, where the issue surfaces.

The picture is not mine, but the phenomenon is very similar to this: View: https://i.imgur.com/qFvR3HB.png


What is this? I did some research and came across something called pixel inversion / pixel walking, is that it? Is it caused by a faulty product or is it the nature of the panel used in this model? I'm now considering buying a different monitor (LG Ultragear 24GS60F-B), is there anything I can do beforehand to avoid this (something to look for/avoid in monitor specs)?

Thanks.
