Hello! I have 4 NVIDIA Quadro RTX 4000 and ASPEED Graphics Family(WDDM) graphics cards on Windows 10 pro and configured mosaic mode for 15 Vestel 55UHD monitors. Display resolution 1920x1080, total 9600x3240. The computer has 64 gigabytes of RAM installed. The processor is intel zeon silver 4208. The driver for the video card is from 2021. While windows is running, everything is fine, but as soon as you restart the computer, there are huge problems, firstly, before loading login and password, the computer is loaded for about 30 minutes, secondly, when the window appears to enter the password to log into windows, out of 15 monitors works 4 random monitors. And there is super braking of the cursor and everything you want to do. Just today this problem occurred and only with 4 times rebooting the computer, and it took 3 hours, with 4 times when entering the password earned immediately 15 monitors and all the glitches disappeared and the system again began to work normally, but if you reboot again, start the same problems and the mosaic is not fully built. Please tell me how to deal with this problem. When all monitors in the mosaic are active, then everything is fine, when when you boot the os, at the time of password entry, only 4 are active, and 11 of them writes no signal, it is impossible to do something, as very much everything slows down.
