HDMI 2.0 4k/60

[Yogafire]

Hi there.
Hoping someone here can help...
I'm having issues with 4k / 60hz on my new gaming rig / Panasonic TV. All works perfectly at 4k / 30hz but if I go to 60hz I'm getting annoying horizontal lines (at best) or black screens (at worst). It's happening on my desktop screen as well as games so not just for intensive usage...

I'm using an HDMI v2.0 cable, Titan X and Panasonic TX-50CX680B and as far as I'm aware all should be good for 4k / 60.
Any help would be really appreciated guys and girls as it's driving me crazy!
Ta.

Broken video drivers or defective video card.

according to Panasonic TX-50CX680B has 3 x HDMI (4K 60/50p with HDCP2.2) . GeForce GTX Titan X also supports HDCP2.2 so i think the problem here is your cable. not only you need an hdmi 2.0 cable but an HDCP 2.2 compliant also.

make sure you are running the latest gpu drivers!

Thanks gents.
Chris - appreciate the detail.
I'd read about the HDCP2.2 after seeing it on the Panasonic spec sheet, but didn't realise the Titan X supported that too as Nvidia don't go into too much detail on their page (at least what I read anyway)...
Makes sense now so I'll look for a better cable. £7.50 did seem cheap.
BTW, I'm on the latest Nvidia driver so should be OK in that regard.
I did read that older amps / home cinemas etc could also be a problem with HDCP2.2 so will try disconnecting that before returning my HDMI cable. Although if that works it means a new amp... 🙁
FML!
