4k tv at @60 fps via hdmi 2.0?

post #1 of 25
Thread Starter 
Im looking into buying one of these two TVs as monitors. But i have heard TVs only run 4k (or 3.75K) AT 30 FPS,

Is 30hz good enough for things like multiple word documents, and pdfs etc on one screen? and will these TVs run 4k at 60fps via a hdmi 2.0 cabe (there is no display port in)
As for gaming i will run all games at 1080p so that should run at 60 fps, right?

Whatever the lowest common denominator is will be how it functions. Your graphics card has to have HDMI 2.0 as well which I'm not sure if the new Nvidias do or not since I haven't looked into them.

If you want to feel what 30 hz feels like, set a custom resolution with 30 hz.

Personally, I would avoid it.

Seiki has a 40" that does 30hz 4k cheaper than both of those, and sometime Q1 we should see a SeikiPro version that will do 60hz. There is a Phillips 40" that does 4k 60hz, but its not available in the US right now.

If you want large format and 4k 60 hz THIS is as close as you get with a TV But you will need a 970/980 for the HDMI 2.0

You can do 4K/60 with 4:2:0 chroma subsampling over HDMI 1.4 if you have an Nvidia card Kepler or Maxwell card (Geforce 600, 700, 800, 900 series)

Nope. Only 970 and 980 support HDMI 2.0

Will it at least run games at 60fps at 1080p? Because the 4k is just for extra word documents.

Yeah you'll get everything except 4K @ 60fps. 4K will be at 30 fps.

Could you recommend a software which will force my monitor to 30fps so that I may see if it is good enough for everyday use?

it depends on your monitor also. .. many monitors wont even do 30hz. If you want to try check out CRU by toastyx. Its a good utility for this type of thing.
