I'm also looking at going UW but waiting to see what is launched at CES. I'd like to go OLED but concerned about burn in risk and the hassle of refreshing the screen every 4 hours.
Ideally I want an IPS miniLED with 180Hz+ refresh rate but there aren't any in UW curved format. Don't like VA at all due to the black smear and poor viewing angles issues.
I've been using oleds for years and not one point have I ran any kind of refresh every 4 hours and I don't have any burn in still.
