Isn't the panel good? Can you not get a driver and replace the current one? It'll turn it into a dumb TV, which sounds preferable than the current thing.

It's strange - the panel looks good for some content, but bad for others. When there is a solid colour on the screen, you can see banding really easily. I also was seeing a bit of subtle colour flickering when watching HDR content on Netflix.

Otherwise, it generally looks ok, but (and I understand that this may just be a preference) I have an older Samsung panel and I think it looks better.

It's the nature of the thing, OLEDs can't display perfectly uniform colours. It's most visible on greys.

Absolutely, it's particularly noticeable on this panel though
