The specs say 120Hz. I can't imagine any display running as slow as 30Hz. It'd be throwing away half the information.
Yep, if I get a better video card or new PC, if it outputs 1080p @ 120Hz, this TV will support 120Hz then!! So that'll be nice.
Unfortunately, the 4K support, going that high in resolution (3840 x 2160) is only possible at 30Hz for this el cheapo model... That's tolerable for videos, but horrible to use as a computer monitor. I really DOUBT I would want that anyway, 1080p is great for my monitor mode needs on my work desk! I'm still tweaking it around, but so far so good. I think I will keep it, especially if I pull the return/open box rebuy so I'll get to keep it for only $191 + tax!
Generally speaking you want to run your monitor at its native resolution. If your PC is outputting 1080p then your monitor will have to convert that to match the 4k panel, introducing lag. A nice 1080p IPS panel with with crisp colors and contrast might be better.
Yeah, good point. You want it set to its native resolution in principle. Thing is, I really wanted a TV. Monitors after 27" start getting really expensive, don't have a remote, tuner or speakers as they're meant for an office and the 2 AOC 27" models I tried kinda sucked compared to the 720p TV I was using before, so that led me back to looking for a TV and finding this one.
WHy only 30HZ? what's the point?
To bring you some 4K support at a really affordable price from the get-go, although prices are dropping in general. It's like 720p HDTVs being able to play video at 1080i 30Hz. Not ideal as 1080p 60Hz, but it's tolerable.
