I do not like the autodimming on OLEDS.
I had one, and the autodimming really ticked me off.
I had a LG and it would also go into screen cleaning mode a LOT.
This would cause all my windows on that screen to move over to my non OLED's.
I guess its not an issue if you have a single monitor, but i run a tri monitor setup, and the OLED just kept ticking me off.
Eventually i replaced it to a VA with high nits and super HDR, and i do not regret it.
It sits in portrait mod and its a 43 inch, so it makes to me the perfect monitor for productivity.
Alienware has a 38inch ultra wide, which i currently use that is essentially half a 4K.
It has 3840x1600p I guess its more like 75% of a 4K.
Its not a OLED, but its a NanoIPS with 4 FALD zones.
That is my primary gaming monitor.
As i stated eariler ultrawides do have its weakness in games that are top down, because you have a much larger FoV sideways then vertical. But they are great in FPS, and also movies.
