Dear ArkanHell,You welcome my friend, i hope too you been able to have everything working, cos Nvidia surround behaviour is weird and they use to add remove and change things with very few or none information about it in the driver changelog.
But even if now im just using 2 diferent connections for the same monitors, before i had all kind of weird surround+VR setups combining at same time DP, HDMI, DP to HDMI using converter, DVI-D, DVI to VGA using converter, HDMI to VGA using converter, and allways worked no matter the diferent timings of the monitors or the connections windows version or even the gpu!!! ( Win 7, Win 8.1, Win 10 LTSC, gtx 660, gtx 780ti, gtx 1080, gtx 1080+gtx 1060 3gb), what really matter is you must match the surround refresh to the lower refresh monitor and since surround standar refresh rates were 60 and 120hz , try this rates before say "aint work" cos if work at lower hz , means it works so the issue can be fixed with the rigth configuration .
I hope you come soon with good news and all your rig working fine, but if you have any issue, just post it, i have more tricks under the hood and maybe another one can help.
Regards.
Wishing you a happy 2022! To be much better than the bloody 2021!
Did your tricks and followed yr instructions and it finally worked my friend. I now have triples all connected with my VR mask on the system without crawling every time to pull off cables etc. The only thing I should do (since I have 4 monitors) is to actually disable from NVidias panel the 4th monitor and then all are playing smoothly and perfect. Now the Surround is syncing at 144hz for all 3 x monitors (2 x on DP and 1 x on HDMI at 144hz working perfectly) without any probs.
Thanks so much for this solution. You really helped me solve a big problem and can now enjoy my Index again.
