Hi! This is my current dual monitor setup for MBP m1 for productivity and PC for gaming. and i think is the cheapest way to deal with it.

current system:

-Bottom monitor: Gigabyte M27Q. acts as the KVM switch for the monitor and peripherals. peripherals (mouse, keyboard and focusrite for my speakers and headphones) are attached with a usb hub connected to the monitor.
-Top monitor: Old Asus ProArt PA278QV is attached with an HDMI switcher, that's also attached to an Anker USB-C hub w/ PD for my MBP.

So this setup has 2 usb-cs connected to my MBP (1 from the gigabyte, and 1 from anker) this current setup has been like 3-4 years, and the problem i have with it is that the top monitor sometimes works, and sometimes it turns on/off every second, or sometimes it just doesn't display anything. So i'm ready to pull out an upgrade to address this.

What i need help on:
If possible I only want 1 connection to my MBP, and when i switch to my PC, 2 monitors and the peripherals should also switch instantly. I'm open to suggestions as to what monitors i need to get and what hubs/dongles/docks i have to use. If you could also suggest a mid range pricing that'd be great!

note for monitors: as long as it has great color, cos i'm a product designer, graphic designer and sometimes deal with photo editing AND has to have a high refresh rate for my gaming needs uwu

I'm also curious what some of you guys run with a dual monitor that has a Macbook and PC as source.

I'm posting this as i'm finding a hard time searching for solutions in reddit. Thank you in advance!!
