Hi,
I would like to display 2D content (4k video playback via html5) via as much as possible screen . What is the best configuration with the latest series cards? I do not like to use FirePro series videocard, because the crossfire supported card are very expensive and it is needs synch card.
What is the maximum for one card system with MST HUB and what is the maximum with 2, 3 and 4 way crossfire combining with MST HUB?
As I said the 3D performance is not relevant, but the price important to stay low as possible.
Thank you for help!

Hi LavX,
Almost all cards, from lets say R7 370 and upwards can support 6 screens when using an MST Hub.
To make Eyefinity feature work, you will need to use the DP output on the card and when using Screens that have no DP input you will need to use active adapters for every screen after the third. An MST Hub is an active device so that would mean you can use “normal” cables to connect screens to the MST HUB.
Now if the GPU will be powerful enough to display your application(s) will depend on the application, the resolution/frequency of the screens as well as your own acceptance level.
I would not advice to connect 6 screens 1080P 60Hz to a R7 370 level card when you plan to run independent high resolution video’s on all screens. For that i would advice you to go at least for an R9 380X or even an R9 390(X) that has double the pixel rate of that of a R9 380X.

Hi MST1407,
Thank you for reply.
I would like use the monitor use as one big display. If I buy a CSV-5400 (4 port MST) then is possible to use 8 display or limited to 6?
If limited then I can buy 2 card, connect via crossfirex and buy 4 CSV-5300 (3 port MST) and I am able to use up to 12 screen?

Hi Lavx,
The cards are limited to a max of 6 screens. The MST Hub will not change that.
And yes you place a second card and again connect 6 screens to that one, they don’t have to run in crossfire for that.
