I just bought my RTX 3090 TI yesterday and i haven't been able to set up more than 2 screens. I tried to reinstall the drivers for the video card, bought new DisplayPort cables and nothing. As of now i only got 1 HDMi and 1 Displayport working, if i try to connect another one it won't work. I checked also on NVIDIA Control Panel to see if the screen at least showed up but nothing.

Good afternoon @DmC
Thank you for contacting micro center. I am sending an email directly to you to get more information on the purchase of the video card.
What's the resolution and refresh rate of the monitors you're trying to connect? Total bandwidth for 1.4a is 32.4Gbps. 4K @ 120Hz will use pretty much all of that.
Turn off fast startup and see if the issue persists.
