Question TV 4k 60hz hdr flickering

[sickb]

Hello !
Im having a problem with my tv running at 4k 60hz when playing games or movies etc. at 30hz the tv is stable but at 60hz its starts turning black for a sec or two.
with a bit of research found out thats propably the cable, My tv says it supports hdmi 2.0 .
My question is if my tv is cable of using an hdmi 2.0b cable!
Thanks in advance

Try a new HDMI cable

Yes make sure its the cable...I've had cables flickering, I had to buy other cables with higher bandwidth. 2.0 supports 4k 60hz while 2.0b adds hdr support. Make sure to get the right kind of cable
