I have a monitor that does 144Hz and Gsync at 2560x1440. It only uses displayport to support these features. Assuming I get a KVM that works with DisplayPort, if I use the KVM with this monitor, will my desktop still be able to use 144Hz and Gsync on this monitor through the KVM? Or does this depend on the KVM?
I can confirm the IOGear GCS62DP and Tripp Lite B004-DP2UA2-K (they are essentialy the same unit underneath) both work for Gsync at 100 hz on my x34. It's displayport 1.2, which is essential for Gsync to work at those resolutions.
Drawback is, the unit essentially disconnects the display from the non-active computer, just as if you had unplugged the cable. So in essense, it actually IS acting as a switched electrical connection.
For me the trade-off is worth it to have 2 computers hit 100hz, instead of 1 at 100hz and the other at 50hz over hdmi.
