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.
