I am also curious that the problem comes from the adaptors. Therefore, I am looking forward to get two 2.1 hdmi to testing two screens surround (my GPU has only 2 hdmi ports) If it works, it means the problem comes from adaptors right? If it work, I plan to use 2 hdmi port and 1 display port to run triple screens. Therefore, I have to find one more reliable adaptor.

From your experience, can you suggest the adaptor (display port to hdmi) that works with NV surround? I find one from Club3d (display port to 2.1 hdmi). I am not sure it is gonna work or not.

That looks like a passive adapter. The problem isn't the adapter itself, but the GPU might have a limitation that won't allow Surround to work with three screens with passive adapters, although I can't find any information about such a limitation with NVIDIA cards. I know AMD cards have such a limitation with Eyefinity. Passive adapters also won't allow the full HDMI 2.1 bandwidth. The Club3D adapter should work since it's an active adapter.

Hi ToastyX

In my case, do you think I need 3 active adaptors DP to HDMI, or just 1 active adaptor and 2 HDMI cables? Which way is gonna be work with NV surround.

Thank you, ToastyX
