Question 1

Does it work in reverse, to connect multiple computers to one monitor, one at a time, rather than having to switch the cable from PC to PC?

Accepted Answer

No. You'd want a KVM switch for that.

Question 2

Is this MST usable with displayPort output and hdmi input? Will I benefit of extended desktop?

Accepted Answer

No it will not. Some more expensive Display port monitors have the electronics to daisy chain more monitors from one port. If your monitors do not have this facility then this is when you need this unit.It allows the connection of three Display Port monitors to one Display Port Graphics card output.HDMI is really DVI with Audio and, each port only supports one monitor. DP is completely different in operation and, can transmit other information as well as display.Hope this clears it up for you.

Question 3

I want to be able to use two monitors independently, ie. move the picture from one to another, will this work?  also, any reported issues with sli?

Accepted Answer

It is a good question, which I wrestled with last year, and it is hard to get good information from manufacturers. By experiment (and having to return a couple of products) I found that the answer - at least for a Mac is, sadly, NO. I gather the story may be different for a PC, but I have not tried one. On the Mac, these multi-port products only give you mirroring. To implement desktop expansion as you want (which was my requirement as well) you have to buy a SEPARATE adapter for EACH SCREEN, then connect them (as many as you like) using a (good quality) USB hub. There are videos on YouTube about how to do this. As this is a bit expensive you should remember that many Apple computers - a Mini Mac for example - already give you two ports: one mini port and one HDMI. I my case, I just bought adapters for these for the first two screens and I use the StarTech adapter for the third screen. The third screen is a beat slower than the others and the colour is not a perfect match, but if you are not running videos this is not a problem. I hope that helps. Good luck!

Question 4

Can this be used for gaming consistently on 3 monitors at 75Hz plus?

Accepted Answer

We've used it for 3 HD projectors running a graphics intensive programme with no problems.
