I don’t like the fact that QDOLED seems to always have shiny panels. I get that it lets the colors pop more and whatever, but I’m not sitting in a dark room. It’s usually well-lit, and no I don’t want to change that. I enjoy the sun shining and I also enjoy some artificial lighting in the afternoon.
So it seems it’s WOLED what I’m looking for, which seems to have matte/diffusing panels mostly.
Fullscreen brightness on either QDOLED or WOLED seems to be pretty meh at best though.
What I also don’t like, even though this isn’t exclusive to OLED monitors, is the missing continuity in resolution coming from a 27" 2560x1440 monitor, which has been a standard for many years. Most 4KUHD “gaming” displays are around 31.5" so if you’d want to get the same amount of real estate per physical inch you’d have to set scaling to 1.2-1.25x. Fractional scaling can already look bad at 1.5x, so this is a mess.
In an ideal world (or in my ideal world at least) there’d be “5K” (5120x2880) 27" panels as standard (I know they exist, but not as high refresh rate panels), so you could replace your 2560x1440 27", use non-fractional 2x scaling and have content at the exact same size as before. Larger panels could still exist, but they’d be closer to a “6K” resolution with the exact same pixel density.
