GTX 1080 problem with 4K resolution when connected to TV

[YakovK]

Good afternoon!

Tell me, please, with the solution of the problem:

I have:

1) Computer: ASRock X370 Fatal1ty Professional Gaming + AMD Ryzen 1700 @ 3600Mhz + 16Gb DDR4 @ 3200Mhz + GeForce GTX 1080 8Gb OC.
2) TV: LeEco SuperTV X4-50 Pro. The passport specifies 60Hz support at 4K resolution
3) Cable: Expensive, HDMI 2.0 with support for 4K and 60 Hz

Eventually:

I can not run 60 Hz at 4K resolution (3840 x 2160). I tried various options and options. Tried other cables. Availlable only 30Hz

What to do?

Hmmm... most people I know run 4K on a display port instead of Hdmi... try DisplayPort unless your tv doesn't have one.

If you really can't then go into Nvidia control panel and tweak it yourself. Go to somewhere under like "screen resolution" or something and then try and change the refresh rate to 60

Did you try rc>Display settings>display adapter properties>list modes>select>apply.
