Startech Canada 4-Port DisplayPort KVM Switch

Two weeks in and it is working flawlessly. No software setup, just plug in the two laptops and use it. I'm not using audio and not worried about 4K. Just using the basic keyboard, video and mouse. One difference is that my keyboard has the old PS/2 connection. Using a PS/2 to USB converter does not cause any issues with the KVM as I've seen on others in the past. A number of KVMs have issues with certain versions of Windows O/S. I have one laptop at Win 7 and the other at Win 8. No issues whatsoever. Will eventually put a third laptop (Win 10) and a desktop (Ubuntu 16) on the KVM as well.

Using with a desktop PC, a laptop PC, and an MS Surface Pro. Monitor switch works perfectly even with the Surface Pro using an external 1920x1200 monitor. Seems to work with all USB devices so far, even an external soundcard. It is worth noting that using this device uncovered a firmware fault on the desktop graphics card which required a firmware update (not just drivers) from NVIDIA to rectify successful detection of the DisplayPort monitor, so it is worth checking that if you are having issues. Not the cheapest piece of equipment on the market but has done a great job for me so far and stops me from continuously breaking cables and cracking my head on the underside of my desk recabling everything all the time...

Bought this item awhile ago as part of a general system swap to use DisplayPort. It has been working fine with a series of 1k and 2k panels without trouble at max res. and frequency. As per usual - StarTech make reliable kit that is well made. Anyway, just got a new 4K panel and thought I would connect it up. It seems that the unit is only DisplayPort 1.1 compliant. This means that it will not do 4k @60Hz. It will only do a max of 4k @ 30Hz. Therefore, looking for an alternative solution to it at the moment. Unfortunately the 4k market for KVMs is a little stale at the moment in regards to DisplayPort. Would wish that StarTech would come out with one that supports 4 ports and DisplayPort 1.2 (at the very least - the standard has been around since 2009).

Failed to output 1080p switching back and forth between sources. I can switch the refresh rate and the KVM will work but as soon as I switch inputs and back again it stops working until I change the refresh rate agian. I've used StarTech KVMs without too many issues, from VGA to DVI flavors and this is the first to not work consistently.

I have 2 computers on Ubuntu, when I start the computer I have my screen, but if I switch to the second one and I switch back to the first, I don't have the screen anymore because the X server crash because the KVM doesn't respond to the displayport during switch... The KVM does not respect the display port standards...
