I want my 4K Pixels spread across a ~30" screen.
Game details tend to scale WAY too small at 4K on a 28" or smaller screen, and 2K isn't ENOUGH pixels on a 30" or 31" screen.
I have to wait though because I also want it at at least 75Hz (preferably 90...more then enough for me). Hoping we see that (and HDMI 2.1, though DisplayPort 1.4 suffices) sometime in 2019.
Oh yeah...AND I want a relatively square aspect ratio, not a damn ribbon....4:3 preferably, 16:9 at worst. I don't need to throw my neck out or feel like I'm looking through the slit in some dark ages helmet.
While I'm stating what should be obvious to manufactures, why not make it TRUE 4K at 1.9:1 (Cinema 4K).
