Question GPU DisplayPorts don't seem to work, but HDMI ports work fine ?

[Squids4daddy]

GPU: GeForce RTX 4070 AERO OC 12G

HDMI port works fine, but the DisplayPorts don't appear to be "on".
Multiple monitors not recognized in Windows 11.
The Gigabyte Control Centers appear to control nothing except the RGB LEDs.

One monitor will run off HDMI, but that same monitor will say "no input" when connected to any of the DisplayPorts.

How can I resolve this?

Update your post to include full system hardware specs and OS information.

Check the monitor's menus: you may need to select the Display port vs HDMI port.

Make and model monitor(s)? Some monitors have drivers - are the drivers installed?
