MST Display Port hub units and active adapters

Hi there

I am thinking about upgrading my graphics card to a Geforce MSI GTX 1080, which has 3 display ports, one HDMI and a DVI connector.

My current setup is Eyefinity, using 5 x 1920×1200 monitors on a Radeon 5950, 4 monitors connected to its display port outputs, and one connected via DVI, All the monitors are identical Samsung 24″ models, 4 of the monitors themselves use DVI to active display port adapters, which were neccessary for Eyefinity to work.

The card I want to use has 3 display ports, one HDMI and a DVI connector – As apparently Nvidia only allows the card to only be able to use 4 of its 5 connectors – Regrettably this means I’m going to need a display port splitter, so wanted to know – having spent a lot of money on my “active” DVI to Display port adapters with the old setup – does it mean I’ll be able to re-use them on with your unit – or will I have to buy “passive” ones?

Hi Derekcfoley,
There is indeed no need for use of active adapters on a MST Hub since this is already an active device. In some cases using active adapters can lead to the signal getting too “strong” causing instable picture. It depends also on the quality and length of the cables that are used.

Ah ok – many thanks for the info!

So will your MST hub product allow me to connect 5 x 1920×1080 DVI monitors to a GeForce GTX 1080 – e.g. if it only has 3 Display port connectors can I connect two via one connector, while using the other two monitors on the HDMI and DVI connectors?

If i am not mistaking a GTX 1080 support 6 screens in total and indeed you can only use 4 outputs of the card.
So with depedning on how many screens you would want to connect and also depending on if you would want to make a Singel Large Surface you can chose the product that best fits your needs. When running an SLS i would advise to use the same screens and conenct them in the smae manner. Ifthe screens all get their own inidvidual video signal, than that would be less important.

Hi many thanks – This is the confusing part of reading their specs. I had a support person from Asus confirm it would work fine with an MST hub. Gigabyte support couldn’t answer at all. I’m going with Asus and will test this at a future date – as , Unfortunately I can’t afford the Club 3D adapter at the moment! Displayport adapter gear is currently so pricey compared to DVI and HDMI !
