Do you use a KVM switch? If so, which one and do you recommend it?

• I have a Windows 7 Pro desktop system (Lenovo) connected to two monitors (monitors that duplicate the display -- NOT extended desktop, NOT multiple display "windows").
• I will be getting a Windows 11 Pro desktop system (also Lenovo) soon. I'd like to be able to switch the display input from one computer the other, and vice versa, with the touch of a button.

In other words, I want:

Computer 1 (Windows 7 ) computer duplicated on Monitor 1 and Monitor 2

Computer 2 (Windows 11 ) computer duplicated on Monitor 1 and Monitor 2

Monitor 1 and Monitor 2 are 12+ years old (still working great!) and do NOT support multiple inputs, as far as I can tell. So I think a KVM switch "for 2 computers, 2 displays" is one way to accomplish what I want. Please note that I don't necessarily need the switch to accommodate a keyboard and mouse, because I can easily have a separate keyboard and mouse connected to each computer; I mostly want to be able to easily switch the monitors' inputs between computers.

• Do you use such a KVM switch? If so, which one and do you recommend it? Is it stable and reliable? How long does it take to switch between inputs?
• Or is there another way to accomplish my desire, using some other piece of hardware?

I use a TrendNet 4-port KVM with computers running Win7, Win10, Win11 and Linux Mint. The keyboard is a Microsoft and mouse is a Dell, both USB. The monitor is a 24" Dell ST2410. The computers have their own speakers. The video ports on the computers are VGA except the Win11 is the newest and needs a DisplayPort to VGA cable adapter [has no VGA port on the computer]. The only solution for multiple monitors I can think of is using 2 splitters for each KVM video port/output but that would only be the same signal, duplicate the view.
