Recently I bought an UHD TV (LG 40UF695V) with an HDMI 2.0. I have in my PC a GTX 960 which can output 4k at 60hz but my tv shows at a corner that is receiving a 4k resolution at 60hz but the input menu over the HDMI icon shows a message that says that it's not compatible with UHD (greater than 4k 50p).
What can I do to use 4k@60hz with my PC? Apparently I have everything to use it correctly.
Thanks /g/
Install Gentoo.
Fuck off, retard.

Please ignore the fucktards. What you require is a HDMI 2.0 compliant cable. One that is capable of transmitting at 18mbps+
Also if it is over a certain length it will require a signal booster. Generally a 3 meter cable should be fine though.
Basically 4K requires lots of bandwidth and those shitty cheap HDMI cables are not up to the job.

Hey grats on the tv but you have one of those fake 4k models

As >>54756450 said a good cable is needed, I'd say amazon basics 2.0 6ft or below.
Now make.sure your tv firmware is updated, you need to downclocl the refresh rate on nvidia cpanel to 30hz in rgb
Check your display, on high end panels like mine you should aim for
ycbr 444 at 60hz with 8bit color limited spectrum
Rgb 8bit with full spectrum
Otherwise 442 or 420 at 10 bit or 12 bit
Another option is custom resolution in nvidia with a refresh downclock but running native is always best

Thanks for the answers, actually my hdmi cable is amazon basics 2.0, 3 meters.
Can I use 60hz from the control panel? Or with this TV I can only use 30hz?

What GPU? AMD don't support anything above 30Hz @ 4K. Only new Nvidia cards like 980ti support 4K @ 50Hz.
Sucks I know.
>>54756956
I meant '4K @ 60Hz'
>>54755944
