MST Question

[cbrunny]

Thinking about getting one of these http://www.amazon.ca/EVGA-Compliant-Multi-Stream-Displayport-200-DP-1301-L1/dp/B00HK8V5KE

Currently I have 2x7970 which has two mini-displayports and a hdmi that I use to power 3x1080p displays. Additionally I have a projector connected via HDMI, so I have to swap the hdmi in and out depending on what I'm using. This is getting to be a bit of a pain and will be more difficult once my new desk is finished. This MST will allow me to use the three monitors on displayport and leave the projector plugged in full time.

One of the Amazon reviews said this:

I was initially running Eyefinity via two Active Mini DP to DVI adapters and DVI output on the VGA card. However due to the fact that the Display Ports and DVI ports use different clocks there was screen tearing present on the DVI out monitor.

which surprised me. Displayport and DVI use different clocks? Why would what the user described cause screen tearing? Given my existing setup with Displayport and HDMI, should I be experiencing the same kind of screen tearing?

Put another way, apart from plugging/unpugging all day long, do these MST devices provide any kind of additional benefit?

bump? Anyone have anything to say at all about MSTs?

For the same cost I suggest getting the ones made from Accell Cables - they are the OEM/ODM for many DisplayPort cables and MST.

Accell's MST can support up to two 2560x1600 @ 60Hz or two 4K monitors @ 30Hz if you decide to upgrade your 1080p monitors (it can do 3 x 1080p @60Hz). The EVGA MST can only do 1080p monitors
