I am so happy that this worked, I had to sign up here to post about it 🙂
I couldn’t find much information of similar setups on the internet so I just bought the adapter hoping it may work, and it did, thanks CLUB 3D!!! Product models listed at the bottom of post for reference:
I now run the two displays from my Mac Pro, the thunderbolt display at 2560 x 1440 and my Samsung LED at 2560 x 1440 at 60hz via the Club 3D adapter. I can confirm it also works at up to 2160p at 60hz too, it’s just too small for me to read as a computer monitor.
I almost gave up until I realised that I needed to restart my Mac for it to take effect lol. The difference is amazing, I’m not sure how I used to put up with the mouse lag at 30hz.
The two tricks to get it working were:
- The HDMI cable out of the adapter into the TV has to be plugged into the “HDMI DVI” input on the TV.
- Also in the picture settings on the TV, the “HDMI UHD Colour” needs to be turned on.
Hope this helps someone else. 🙂
