A cable is a cable when it comes to HDMI. Its not analog were it can lose signal. It either works or it doesn't. Just make sure its 1.4 standard.
My old 25'' foot HDMI cable (which worked perfect on my old 1080p HDTV) doesn't work on my 4K HDTV. Don't know the name of it (bought it ultra dirt-cheap off NewEgg, a while ago), but the signal it sends is funky-looking - flashes on the screen b/t the the picture itself and a blank picture; picture can work and turns pink or white w/ other nonsense; and other ugly non-sense you can think of. It's also very skinny cable, too.
I use namely SteamLink for sending from my 4K PC to my 4K TV. That works fine and dandy.
I do have a nice thick 6 foot HDMI cable (again, another no-name cheap cable) that I sometimes connect from my 4K laptop to the 4K HDTV - and that works just fine, when I do so. No issues.
