Can someone recommend a KVM that works? I've been looking for a couple of years now.

Requirements:

2-port, 1-monitor, DisplayPort 1.4 KVM

Has a wired push button switch (and cable can be extended if needed)

Runs at 3840x2160 @ 120 Hz (or 60 Hz)

Works with HP docking station (HP USB-C Dock G5 for business)

Works with Classic 101 Black Buckling Spring USB keyboard

Works with Logitech TrackMan Marble Trackball

Works with HP laptop and custom desktop build (NVIDIA T1000 GPU)

Anti-requirements:

Does not intercept keystrokes (or can be disabled)

Does not intercept mouse scrolling (or can be disabled)

Does not randomly repeat keys

Does not block certain keystrokes (e.g., ctrl+shift+t)

Does not let Windows laptop go to sleep

Does not require manually re-waking Windows laptop by pushing power button

Does not require switching back-and-forth to re-establish connectivity to both computers

Does not take more than 3 seconds to switch between computers

Does not randomly blank the screen for 1 second

Does not require unplugging and re-plugging the USB keyboard

Here's the setup showing both computers and the push button switch:

I have tried:

IOGEAR GCS62DP (almost perfect; kills keyboard after 60 swaps; RMA'd)

DiamondTiger KVM Switch EDID 8K@60Hz, 4K@144Hz, DP 1.4 (repeats keys, blanks screen, has screen tearing, and many other issues)

CanadaComputers iCAN HDMI USB KVM Switch 2x1 with Switch Extension 4K 60Hz (completely blocks certain keystrokes)

Wendell's Level1Techs Store offers a highly recommended KVM, yet lacks a wired toggle button.

What other KVM switches are available that "just work" and have a wired push button for switching?

The next KVM I'm thinking about trying:

GiantMatrix with LINDY EDID Emulator

ATEN also has a switch, which is on par with the IOGEAR (4K @ 60 Hz, no EDID):

2-Port USB DisplayPort/Audio KVM Switch
