Question LG CX - Faint horizontal lines/grid in HDR


Novice Member

Hello 😊

Bought a LG CX about a month ago, and have a 1 month return window left.

I have these faint horizontal lines running across the entire screen (see pic). They are especially prominent in bright HDR content, when panning up/down in games like Ghost of Tsushima or RDR2. It is like a DSE.
If I look closer, a can also pick out faint vertical lines (only in HDR/bright scenes), which, combined with the horizonral lines, make kind of a grid pattern.

It even seems to me that the issue is getting worse.

The screen uniformity is otherwise great, with almost no vertical banding, tinting or otherwise.

Should I return it (panel lottery), or is it normal with OLED technology?

Exactly the same happens to my 65CX. Did you return your set? I'm thinking of returning mine because even after 2 manual pixel refreshes the lines are still there.
