Question 1

What refresh does this support?  Is there virtualization?

Accepted Answer

The trendnet site has all the specs. NewEgg won't allow links so you'll have to find it yourself. Hint: trendnet dot com and then the path /products/kvm/2-Port-Dual-Monitor-DisplayPort-KVM-Switch-TK-240DP

Question 2

My my corsair K79  RGB MK2 low profile  keyboard work through this KVM?

Accepted Answer

I have had issues w/more advanced USB keyboards but only when connected to the keyboard-specific USB port. I've had no issues w/the regular USB 2.0 ports in the back.

Question 3

does the inactive computer lose the screens? (i.e. will it need to refresh the moniters when switching back?)

Accepted Answer

Yeah, they do. Whenever I switch over, the previous machine shifts windows etc to the remaining monitors (I only KVM 2 out of my 4).

Question 4

Does it already come with the two USB type A-B cables you need to connect to each computer? Or do you have to buy those separtally?

Accepted Answer

You need to buy all cables separately except for the power adapter.

Question 5

Why are there two display ports for each pc? Do you have to use both? If I only use one port per pc, will it still display to both monitors or just one?

Accepted Answer

If you want two displays coming out of your computer, you need two cables from each computer. To computer A, if only one cable is plugged in then it will only detect one monitor. This is not a DisplayPort topology daisy-chaining device, it's a switch. So that means you will need two cables from each computer, and two cables total for both monitors. This means for the whole setup, you WILL need 6 displayport cables. 2 cables from Computer A to TK-240DP, 2 cables from Computer B to TK-240DP, and one cable from TK-240DP to each individual monitor.
