Wondering if Apple Support's article (link below) can help:
If your external display is dark or low resolution - Apple Support
Eg: says:
"Check display brightness:
If your external display is dark, make sure that its brightness hasn't been turned down.
If your keyboard and external display are made by Apple, you can use the Brightness Up key on the keyboard to increase brightness. Or choose Apple menu > System Settings (or System Preferences), then click Displays and use the brightness control there".

Make sure the display's USB cable is connected to the computer.
Thank you for your reply, sverrewh,
and for giving us a little more info. on your needs.
Perhaps this answer given in an older (non-Apple) forum may help:
(Seems it was working for macOS Catalina, so may work on Ventura)
Thank you for your answer! But I cannot find any ruler to darken my screen. I have changed USB connection, but it did not change anything, the ruler is still blank.
Thank you! I changed the USB connection directly to the hub, without success, ref. my previous post.
Same issue. The brightness control is unadjustable. The USB connection from the LED Cinema Display is connected through a USB 3.0 hub.
Wondering if restarting your Mac (Apple menu > restart) will help.
ie: (deletes temporary files, may update recent setting changes, re-establishes connections, and much more).
Thank you for your reply. The problem is apparently solved by Mac OS updates. My screen is now working perfectly.
