I could get my Sony TV to display 4K@60Hz 4:4:4 and my LG C2 OLED to work at 4K@120Hz 4:2:0 but it was flakey as all get out. I was expierencing black screens at every start up and wake from sleep. The only way I could get my computer to start (with a screen active) was to unplug the HDMI ports...

I saw one review of a DisplayPort adapter on Amazon say that VRR worked when they bought it a few months ago. So, they bought two more of the same brand and neither of those supported VRR. I think the supplier used different internals for a refresh while keeping the brand/shell of the product. I...

It's funny you mention a heatsink because I attached an old M.2 heatsink to the Reborn DisplayPort adapter. It seemed to help greatly but it's not something I'd recommend. Probably the CalDigit Adapter would a better choice. I am disappointed though the Sapphire Pulse RX 9070XT isn't working...

I bought the Reborn DisplayPort 1.4 to HDMI 2.1 Adapter and tested it with my LG C2 TV. Everything worked but VRR, also the HDR is not certified so results may vary. I will say though it got incredibly hot running 3840 x 2160, 120Hz, 10-bit, YCbCr4:4:4 with HDR. There were a lot of complaints of...

Ah, I see what you're saying. The adapter worked with the 3080 but not the 9070XT. I saw similar results from the reviews of the adapters on Amazon. NVidia users had glowing reviews and AMD users reported not all features were working, in particular VRR.

I've seen mixed results from these Display Port adapters. That's why I only ordered one as a last resort. I'll test it with my C2 when it arrives later today. As for now LG C2 is working at full bandwidth but only when I'm using one HDMI port on the card. On another forum (I think it was an...

I think you are 100% correct in this. I have this exact same card. The Sapphire Pulse RX 9070XT. I have both HDMI ports connected to a Sony 4K TV at 4K@60Hz and an LG C2 4K TV at 3840 x 2160 @ 120Hz but 4:2:0 and no HDR. The C2 was working perfectly when connected to a 3080 but I kept...
