This panel does have a little more banding than typical though I don't generally notice it except in very specific circumstances and only really because I have a decent quality IPS alongside it.
Sadly its kind of the price to pay for a responsive monitor of this resolution and refresh rate until tech moves on
Thanks Rroff. At least I know its not just me. As I said, nothing major, just the odd scene here and there, easily live with it as the upside it 144fps goodness
