Pros: I have only had this unit a few days. So far it has performed well.

Cons: DisplayPort and USB Cables are NOT included with this unit. I feel like this is just something that users need to know. You'll need a total of 5 DisplayPort cables and 4 USB A to B (Male to Male) cables to hook this up to four computers.

Other Thoughts: I don't understand why the cables are not included. Seems a big miss here. It's not like the KVM is usable without them.

Pros: Woks as Described
Well Constructed
Keyboard shortcuts work well

Cons: No included cables
No remote switch

Other Thoughts: 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 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.

Pros: This would be a good Display Port KVM if it included full port emulation.

Cons: This KVM does not do port emulation on everything, which all KVM switches SHOULD do. When you switch to a different PC the last PC you were on thinks your monitor was disconnected... this should NOT happen on a KVM, the PC's should never know when you switch to a different PC. It's ridiculous to give this kind of money to a company for a for a product when they take shortcuts like this an leave out critical features out.

Other Thoughts: Since this KVM doesn't have full port emulation the Pros don't really matter much to me.

Pros: Operationally the KVM switch works well. It is inexpensive compared to other DisplayPort switches

Cons: When connected to a 27" 2560x1440 IPS panel, the panel flickers off and on randomly (generally 6 or more times per hour with the "off" ranging from 2 seconds to just barely noticeable flicker. I had to replace the switch with a different model (which works fine). The other con is the non-standard hot keys for switching input.

Other Thoughts: It is too bad that the DisplayPort signal is unstable otherwise this would be a device I could recommend.
