Hi everyone,

I bought the ASUS ROG Strix XG27AQWMG yesterday, and overall I’m actually really happy with the monitor and the purchase.

However, I noticed some horizontal gray banding on the panel, especially at certain brightness levels (most noticeable around 70%~95% gray). The bands stay in the exact same position and don’t move. I took this photo at 80% gray.

What surprises me is that I usually only see people talking about vertical gray banding with this monitor, not horizontal banding.

I’ve already run the monitor’s Pixel Cleaning several times, but unfortunately it hasn’t made any noticeable difference.

I can also notice the horizontal grey banding in games, especially in the RDR2 prologue in the dark, snowy environment, where the overall image naturally appears grey.

Is this something that can be considered normal panel uniformity and something I should just get used to, or would you recommend exchanging/returning the monitor?

I came across another Reddit post where the LG G5 also showed horizontal grey banding, and some people in the comments said that it becomes less noticeable after around 100 hours or can even disappear completely. Is that actually true?

Thanks in advance!
