This isn’t a specific response to anyone, but I just picked up this monitor earlier this week (a marketplace vendor had it new for $350 plus tax, no shipping charge, but Amazon’s now selling it for only a bit more directly):
and can highly recommend it so far.
The Wirecutter is currently recommending something else as best 4K monitor, but there’s no sign they ever tested this model and this is by most accounts the updated version of their previous pick (an older LG monitor without the HDR) and even better than that. This is also cheaper than their current pick and the only advantage that monitor appears to have are a couple of USB ports and a slightly longer warranty. Woo? I wouldn’t be at all surprised to see this hit their top tier once it does enter the mix.
It’s got gorgeous colors, excellent viewing angles (it is IPS, after all), has a very convenient and well designed onscreen display (and supplementary software that lets you make additional changes like screen splits and per-application automatic mode switching), a very smartly designed stand that is very adjustable, HDCP 2.2 support (so you can do native 4K streaming and potentially 4K blurays), HDR10 (albeit I haven’t found this terribly useful so far), etc. Love it.
Personally I highly recommend 4K for gaming - I think the beauty it brings is much more important than maintaining 60+ fps, and you’d be surprised how many games can do perfectly adequate framerate (if not necessarily 60) on a 1080, or even a 970 (which is what I had when I first switched to 4K). But even if you don’t want to risk that with the latest games, 4K monitors downscale to 1080p without fuss for those games and then you can enjoy the expanded resolution for day to day use, media, and older games. It is so worth it. And then when you do make the plunge (perhaps when there’s another generation of graphics cards that can consistently do 60+ in 4K), all you need is the new card, not that -and- a new monitor.
