MacOS Detects Incorrect External Monitor

Okay so I have a 2019 Macbook Pro 16in running Big Sur. I have BenQ PD2700U (27in) external monitor that is supposed to be 3840x2160@60 and every time I have to disconnect my external monitor, I'm in for a 10-15 minute battle with my OS.

My Mac will detect the same monitor as a 30.5in at 1920x1080@30/60 or as a 61in TV at 3840x2160@30, and rarely does it actually detect my monitor as what it actually is (27in). After about 10-15 minutes of restarts, unplugging and replugging my monitor in, trying different ports, etc, it will eventually detect my monitor as the 27in - 4k@60 and I can get to work.

I'm kind of at my wits end, when I was running Catalina the monitor worked fine for like a whole year, and the second I was forcefully upgraded to Big Sur I had no end of problems with this monitor.

Here are some things I have tried:

Change settings and refresh rate manually - When it detects the 30.5in the max resolution is 1920x1080@60, so that doesn't help me, and the detected 61in has a max resolution (and refresh rate) of 4k@30... so that doesn't change anything.

Different Cables - I'm using Display Port to USB-C, it's the only cable that I could ever get to actually display the monitors default resolution (4k@60). I have tried HDMI cables, different Display Port Cables, tons of adapters and nothing seems to change anything.

Display Port 1.1 VS 1.4 - I read somewhere that Big Sur had an issue with Display Port 1.4 so I changed my monitor back to 1.1. This made my Mac exclusively detect my monitor as the 61in at 4k@30, I could never get it to detect anything else. Changing it back to 1.4 resulted in my daily battle, but I can eventually get it to detect the 27in.

Zap The Pram! - Nope

Reset SMC - Nada

I've tried different monitor settings galore and nothing changes. The same monitor works fine on my Windows 10 Laptop/Desktop as well as Bootcamp Win 10 on my Macbook, not to mention it worked fine on Catalina, so I don't think the monitor is the problem.

I've seen some people say "wElL jUsT wOrK iN 4k@30" and I did that for the first few months of having this problem as I waited for a Big Sur update. Problem is that I edit videos that are usually 4k @ 60FPS for my job, and having a monitor at 30hz makes editing properly difficult, and honestly this is an unacceptable solution after dealing with this problem for months.

As I said, I'm at my wits end, I'm more of a Windows guy. I worked IT L2 & L3 for a few years at Windows based companies, I know enough MacOS to solve most problems, but not for something like this. Is there something I'm missing? Normally I would just go into device manager and manually change the device drivers or force 4k@60, but I cannot seem to find anything like this for Mac. Is there some setting or something that I could change the detection manually?

I'm really kind of done with this, I just want my monitor to work, lol. Any help would be greatly appreciated.
