I have a new Radeon RX 6800 a XB270HU. and an OLED B9 plz help with setup.

[SerHoneyBadger]

I have a HDMI 2.1 cable plugged in to my OLED and it has wierd flickering issues with the colours. My XB270HU is stuck on low res and i can't get both screens higher then 60 FPS

MY XBU should be able to go up to 1440P 144FPS
My OLED should be able to achieve 4K 120FPS

I would love some help on this. I keep tinkering but i seem to make things worse.

There are know issues with HDMI 2.1 cards and dual screen set ups.....

Both Nvidia and AMD royally fucked up the drivers and VBIOS on launch this time around.

 

Try to connect the TV first check if you get no flicker and can drive it 4k 4 4 4 120Hz if not then check cable a lot of the so called 2.1 cables do not deliver 2.1 specs.

How long is the HDMI 2.1 cable anything longer than 3 meters and you are basically guaranteed to have issues.

-Its a very short 12 Euro Cable i bought online.
-How do i set up the resolution and 120 hz properly? Do i use a custom Resolution?
-I have set my Colours to 4.4.4 Full RGB 10 BPC on the OLED

-How can i check my cable?

I have not used Radeon in a while.

But you need to set the resolution in the AMD control panel

This shows what signal comes into your TV.....

So you at least know what it is receiving. It is a TV command independent of source

My Colour flickering is gone at 8BPC Limited RGB. I truly don't understand this anymore. The Card runs well though so thats not the problem.

Get a new cable.....

Probably the cable cant handle the bitrate

try one of those that have the holographic certificate from the HDMI fundation.
