Will it work with Logitech wireless USB keyboard and mouse? Like the Unifying kind?

Hi... they will work, only on 1 PC though, once the PC is selected. Unless you have 2 sets of wireless plugs (one for each comp.) I have not actually tried, but in theory, it may work. I imagine you can get an extra wireless plug, so each PC has a connection to the 1 keyboard and mouse. I can switch between the 2, but the wireless plug needs to be moved over to the comp. I am working on. Also, I really like this KVM, fairly inexpensive, I researched many, and I believe this is the only setup that does DP 1.2 for each PC. (that use an ultra widescreen display with resolution of 3440 x 1440). You will need a graphics card the has the Display Port 1.2 connection. This is the only KVM that can do the high resolution. Most displays and KVM's only do 1920 x 1080. Good luck, ...Bob R.

Does this switch work with gaming keyboards and mice?

It should work fine if they are standard USB. I use a USB hub with a wireless Logitech keyboard and the MX Revo mouse. I switch back and forth between a Lenovo work laptop and an Intel i7 NUC and it works fine. For the price, it's hard to beat this KVM.

Will this KVM handle a monitor running at 1920x1080@144hz?

I think so. Although I'm not running 1080p at 144hz, but 4k at 60hz, it works fine. The 4k pixel clock at 60hz would be about 4x the pixel clock for 1080p at 60hz, so that should cover up to 240hz of 1080p... One thing to consider regarding this product is that it doesn't seem to provide a "keep-alive" signal on the USB, so the keyboard/mouse drivers on the idle system may shut down, making the switching between systems subject to delays. Great price, though. I paid a lot more...

Does this switch work with G-Sync?

Have this connected to an Acer Predator and an iMac, both with displayports, and gsync works just fine.

Does this support connecting a MST Hub to the single DisplayPort output? I am wanting to share 3 monitors via MST DisplayPort Hub with 2 PCs (via their single DisplayPort 1.4 output).

Yes, the ATEN CS782DP supports MST (Multi-Stream Transport), enabling multiple monitors to be used via a single DisplayPort.
