Good FreeSync + HDMI 2.1 KVM Switches and 40+inch 4K 120Hz+ LCDs for both production and gaming?

I'm interested in getting a new KVM switch in the following weeks. I've only owned one and it died after eight months though it was very convenient to switch to my Mac Mini to test Safari out on occasion. However I have come across The Witcher because it was free on GOG and it tore frames like crazy and unfortunately my switch (and possibly my monitor) apparently do not support FreeSync, at least via HDMI.

I'm usually against HDMI because they explicitly want to hide the actual version numbers of what devices/wires/converters etc support what version which is extremely anti-consumer. Unfortunately I've read many reports of others with different monitor types that have had the same insanity-inducing DisplayPort bug where the screen just stops working until you outright reboot the computer. Since productivity is easily what I spend the vast majority of my time doing a reboot is basically sacrilegious. My

• FreeSync + HDMI 2.1 for 4K 120Hz support.
• 7.1/8.1 analog audio support.
• USB 3.0 support.

I'm also going to be looking for a new LCD monitor:

• Must be 40 inches or larger, 3.8K makes my GUI too small for productivity at 32" and I don't use GUI scaling in Windows do to web development conflicts.
• 3.8K (there are no 4K gaming monitors on Newegg) that can do at least 120Hz.
• FreeSync over HDMI 2.1 for 3.8K / 120Hz support.

If I only cared about gaming I'd just get an oversized HD screen however I have to test high resolutions while doing web development. I can live without replacing my monitor for a while though a KVM switch that explicitly advertises the specs I need is something I'd like to purchase before the end of this month.

In regards to audio I don't know how HDMI is supposed to take the audio from my dedicated audio card, pass it to my video card and then somehow connect to my 5.1 speaker system. I'd be very interested to see a 5.1 or greater setup using that should someone have a recommendation of using audio over HDMI.

I can't speak for Switches but I am totally enjoying the Gigabyte 32QC. It has a 165Hz refresh but it is 144hz over HDMI.

I think they do have a 40" + (sorry didn't see that) panel. Currently LG and Dell are probably your best bet.

The KVMs produced by Level 1 Techs are easily the best ones that I am aware of

Wendell has put significant effort into working around common KVM issues with for their products.

If you find an HDMI 2.1 KVM, let us know

With HDMI 2.1, the VRR support to look for should be HDMI 2.1 VRR. Freesync and GSync Compatible branding will be blasted over that but the base standard is what you ideally want to have support for.

VRR support is kind of so-so and it seems like the only sure way is to test. I have a DP 1.4 switch that does work with my GSync monitor but finding that out from specs was pretty much impossible. Plus, I could swear all my previous VGA and DVI/HDMI switches back in the day managed to work without disconnecting the monitor when not sending picture there which is annoying as hell. Granted, most of my previous KVMs have been second-hand high-end models.

For 4K 120, a DP KVM switch is a much better selection. I suggest go with DP 1.4 KVM switch.

I had two 1440P monitors one 3440x1440@144hz and one 5K@120hz connected and ConnectPRO UDP2-12AP DP 1.4 KVM switch.
I think it the only DP 1.4 KVM switch that can support dual 4K120hz multi-DP gaming monitor sharing.
To see is to believe. Here is the live demo link of my setup.
On the demo setup, those two monitors are both AMD FreeSync. certified.
