Ventura and two external 4k monitors

Hi! Yesterday I updated to Ventura and already regret it. I have an M1 PRO 16" MBP. I have two LG 27" 4k monitors, one connected through HDMI and another with a dongle through USB-c. These were working perfectly with 4k resolution and perfect scaling in Macos Monterrey. Now, I can't use them in 4k anymore. Both are at full HD (1920x1080). Screen config only lets me change the resolution for one of them, and if I do it, everything becomes super small, not being properly scaled.

Please help!

MacBook Pro 16″, macOS 12.3

I had a similar problem - my C49Rg9x display was DualQHD (5120x1440) before Ventura, then it went to 3820x1080 (DualFHD) after the upgrade. I have a second external monitor that is FHD. When I unplugged the second monitor, I was able to get full DQHD on the first, but anytime the second was plugged in it reverted to DFHD.

Turns out I was able to "solve" the problem by switching the settings in the Displays of System Settings. After unplugging and replugging the externals, I eventually got the "Use as...larger text...more space" setting to show up for my C49G9x. Switching to the middle option and then back to the More Space option has now allowed the monitor to stay in the higher resolution. So far so good....
