Hi, I'm having issues with my 6400 card, I'm using it for my HTPC, which is connected to a Samsung Smart TV, in the Samsung TV I have enabled Input Signal Plus, so HDR in enabled and working but as the Subject says, I can't enable FreeSync and Color Depth is limited to 8bpc, I tried with HDMI to HDMI to my receiver (DENON AVR-S760H) and Display Port to HDMI with no luck, I also tried directly to my Smart TV HDMI ports.

- AMD Adrenalin: 23.2.1
- Windows 11 22H2 22621.1265
- Core i3 12100F
- ASUS H610M-A D4 BIOS 2212
- Samsung Smart TV QN50Q60AAPXPA

i only can say thet 10bps with high hz ist not suported by hdmi. Maybe lowering the hz to 60hz will solve the problem. Are you sure that your tv supports freesync and 10bpc? Never seen a TV that supports AMD Freesync, but havn't looked for a while.

Your TV supports neither VRR nor Freesync, and it does not have HDMI 2.1, only 2.0 which has lower input bandwidth.

Buy a newer LG with hdmi 2.1 and freesync, then it will be perfect for HTPC.

Yes, it does support VVR, you are right, it only has HDMI 2.0.

Also when I use an nvidia 1050 ti, I can set 10 bit, with the 6400 I'm limited to 8 bit.
