I wasn't sure if this is the right forum to post in... I figured its amd gpu / driver related so i thought i'd give it a go. I have an r9 290 running the 16.1 drivers. I purchased the Club 3D adapter (link) with the amazon HDMI 2.0 cable (link) and I'm unable to get any signal at all on my 4K TV (link). If I plugin the HDMI 2.0 cable into my HDMI port on my GPU I get 4k (30hz). I do use the display port on my GPU for my 1080p 144hz monitor so I know it is functional at least with 1080p. All of the HDMI ports on my tv are 4k 60hz capable so I know thats not the issue. Does anyone know if there is there any specific setting I need to set on my driver settings to get this to function? Thanks in advance update: It appears to be the Club3D adapter. I plugged the HDMI cable into my 1440p monitor which is only 1.4a and got 1080p. I plugged the HDMI2.0 cable using the club3d adapter into Display port and the display signal blinks on and off. It's possible the one i have is faulty, but has anyone else had success with this adapter or otherwise?
