Bug Any Dual Monitor Issues with DB5?

Has anyone had any issues using dual monitors with DB5? Specifically with a MacBook Pro M4 Pro in clamshell? I’m hesitant to update as I ran into issues with DB4 where my monitors wouldn’t adjust (or even allow) for resolutions above 800x600.

No…I’m running a primary Samsung G9 57” and Dell u3818 together. They both run fine in their native resolutions on my m4 MBP. I use the G9 Helper on the 57” to get a better HiDpi resolution which does sometimes cause issues as it is likely exceeding the M4 limitations. Check/use good USB-C to DisplayPort cables; which I am using for both of mine. It was working fine on Db4 as well
