4K or 5K monitor for Mac Mini Apple M4 Pro - Video & Photo Editing

Hello all!

Just got the Mac Mini Apple M4 Pro and am now having to find a good quality non-Apple monitor for the first time (Apple displays are too expensive sadly). I am spoiled from years of using my 2017 27-inch iMac 5K. Hoping someone has recommendations for an affordable 4K or 5K monitor (27 inch and up).

I will be doing Photoshop and video editing using Da Vinci Resolve. I hope to keep the price to under $500 if possible.

FYI - I bought a BenQ PD2705U Mac-Ready Monitor 27" 4K UHD, but their Display Pilot 2 software does not seem to work well with the M4 Pro. And the software does not work at all since the latest Mac OS update (Sequoia 15.1.1 (24B2091). Which means I cannot control brightness or speaker volume from my keyboard, nor can I calibrate. I can use their "hot Puck" device but let me tell you that is very time-consuming when you adjust volume frequently

Thanks in advance for any suggestions!
