Nice try but I’m keeping my even more instant instant noodles to myself.

I’ll give you a hint though, the secret is in being ok with pumping boiling water into your stomach.

Not really… just a slightly higher end of gear, most of dells professional series will do it from memory, the gigabyte on my desk does it.

Yeah… tend to agree - it’s doable but OP would be reaching for some fairly hectic gear to solve a pretty small problem. Consumer monitors with PIP definitely exist and would be cheaper.

If all you’re looking to do is nicer input switching, a KVM switch would be a better solve.

Capture cards would be more useful if you wanted to record the gaming sessions. AFAIK they will always introduce latency as they are usually designed for a situation where that is fine.
