Just get an OLED!
I got a PS5 Pro last month without knowing all that much about how much power I was leaving on the table by not upgrading what was basically an entry level monitor which supported an HDR signal, but wasn't capable of rendering true HDR.
Yesterday I bought a MSI MAG 272URX QD-OLED.
Good lord above.
The PS5 Pro felt like an upgrade. The combination of the Pro and the OLED feels like a generational leap.
I would go out on a limb and say you owe it to yourself to get an OLED tv or monitor if you have a Pro.
