Seems like ASUS have tried to think of everything. The uniform brightness setting seems like a good way to avoid ABL in desktop use.TFT Central have their news piece up covering all the official info on the Asus 42” OLED PG42UQ as well as first impressions and hands on from the Uk launch event last week
Lack of BFI is a bummer but I guess that's on LG not wanting to support it anymore for reasons unknown. I found the 120 Hz BFI on my CX 48" worked well enough for SDR content to be a useful extra option.
I do wish instead of 1x DP, 2x HDMI 2.1 and 2x HDMI 2.0 ports they had 2x DP and 2x HDMI 2.1. It seems like nothing comes with multiple DP ports anymore and that really sucks when the only things that are HDMI 2.1 capable are latest gen GPUs (I've got a 2080 Ti) and latest gen consoles.
