For several years, I used a 4-Port external KVM switch with PS2 connectors for the monitor and mouse. It was time to upgrade. I was looking for a USB switch and the StarTech (SV431DVIUAHR) with audio out and microphone in fit the bill. My only complaint is that you only get one (1) StarTech KVM cable set for the price. You have to purchase three (3) other cable sets to have the full 4-port functionality, which I did. Still and all, it is a very good 4-Port 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.

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 bought 2 to do multiple setups for Deployment. Both have issues: flashing the screen (mostly off) and not catching a signal on start up so never seeing a screen. Lastly one of the two only works with two or less of the ports connected. I cannot find a firmware update or support for these issues.
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).
I've had a decades-long love/hate relationship with KVM switches. When they work, it's great, but often past versions would lock up, not sync, etc. This one works perfectly, at least for 4K 60Hz video (that's all we're using it for). And the heavy metal case keeps it from sliding around when you push a button on the front. UPDATE: Originally we only used this for switching video, but now I have a PC and a Mac connected to it, sharing a mouse, and both sending music to an external DAC and headphone amp. This also works perfectly. (The only reason I'm not also sharing a keyboard is that keyboards have different keys for PCs and Macs.)
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...
This is working well for me; however, only 4 stars because it does not work with certain setups. My display is a 4K IPS monitor from Monoprice. My late 2013 Macbook Pro connected with mini-displayport to the displayport on the monitor worked fine. However; my late 2013 Macbook Pro connected with mini-displayport to the KVM displayport, and then to the displayport on the monitor did not work (distortion on the screen and frequent blackouts). Later I upgraded to a 2018 Macbook Pro and connected a USB-C to displayport cable to the KVM displayport and then to the displayport on the monitor and all is working well. Beautiful 3840X2160@60Hz.
I was hesitant to get this due to the mediocre reviews on this and other sites. I have a Desktop PC, a Mac Mini, and a PC laptop to connect to my new 27" Dell Ultrasharp monitor. The monitor requires displayport to get full resolution, and this was the only reasonably priced option for 4 port displayport KVM....So I decided to give it a shot. It works well!! All devices plugged into USB (headset, webcam, wireless keyboard and mouse) are recognized by all devices and work well. The monitor has a USB hub and I plug that into the KVM's hub and all devices work fine. Switches between computers are fairly quick, although the monitor momentarily goes into power save for a half second during the switch. Audo comes through displayport just fine. The keyboard shortcuts work ... MoreI was hesitant to get this due to the mediocre reviews on this and other sites.

The keyboard shortcuts work well to switch devices, or you can press the buttons on the unit. My last KVM had a small wired remote so I could tuck the unit away. This one does not have this feature and I sort of wish it did...but I think I can make due with the keyboard shortcut (ctrl-ctrl-1 for device 1; ctr-ctrl-2 for device 2; etc) I could not be happier or more pleasantly surprised with this purchase.
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...
