Looking to buy a reliable KVM switch that can handle high resolutions and perform smoothly without any glitches, issues, etc.

This is the monitor I have: Samsung Odyssey OLED G9 49-inch
It supports 5120 x 1440 at 240Hz.

I have two machines connected to it, a desktop with Ryzen 7600 and Nvidia 3060Ti (might upgrade to RTX 4090/5090 later this year for LLMs) and Macbook Pro M2 (for work).
Right now, it is cumbersome to switch between the two. I want the display, keyboard and mouse all 3 switching to either with just one switch.

I need a KVM that can handle at least 4K@120Hz (i.e. 8K@60Hz) with EDID support. Most listings on Amazon are limited to 4K@60hz and EDID is lacking.
I've used generic KVMs before and many of them either lagged or went blank while switching and had to switch back and forth 2-3 times to get it working.
If anyone is using a high performing KVM, please suggest a model and where to buy it from. Budget is not an issue, but it should be reasonable and not crazy.
 
Don’t go for a display KVM switch. Use it only for USB. Doesn’t display automatically switch anyway? I hope you’re using DP for your desktop.
Yes, I do use DP for desktop. Need display KVM as both systems are simultaneously on and switched back and forth randomly.
