You don't mention which GPU you have. Pre-Kepler GPUs can only scan out 2 outputs at a time, so even if you have 3+ connectors on the board, you can still only have 2 of them active at a time. This is a hardware restriction. Kepler+ enables 4. If you check "lspci -nn -d 10de:" it should give you all the NVIDIA hardware in your machine. Cheers, -ilia P.S. Looks like I provided this very same advice to you without response on Jan 16, 2024. So it's an annual thing?
