Hello,
I'm trying to switch to 4k resolution on my 4k TV, using a 100ft 2.0b HDMI cable by Qual Gear (it is a 4k cable), but when ever I try to do that, I get the error "no signal", I wait 15 seconds and it reverts back to FHD resolution.
My graphics card is GTX 1080, which supports 4K.
What can I do?
