I think the are many issues with Sierra and that everybody is really busy trying to fix that with drivers …
I have heard of users not getting it to run, but “a lot of lag” is not something “common”. Like it is not receiveing anough power or something … you checked the USB Cbale to the CSV–2302 ? Does it make a difference if you connect the Macbook to the power adapter ?

Hi MX900,

What Notebook you have ?

[MST1407]

Hi Dragonborn,
Indeed a weird one !

I would advise you to do this:

–          AMD Divers

I have heard quite a few strange behaviors with regards to Radeon HD series cards in combination with AMD Drivers after version 16.8.3. I know AMD made many driver updates after that, however all aimed at RX400 series and non that I know of for HD / R7/9 200/300 Series.

I do hear end-users with HD / R7/9 200/300 series Cards reporting that 16.12.2 (or later) also works quite decent for them.  Especially when using the upgrade feature to update drivers can give issues, because old files can remain in the registry of windows and can be “in the way”. Please make a new clean driver installation to make sure that part is ok.

Please uninstall the current Graphics driver and all related Graphics software like Afterburner/GPU-Z or whatever graphics related software you might have installed. Best way to remove Driver Software is to boot Windows in Safe mode, so the registry can also be cleaned. When you system does not allow you to do that, you can also use a program like DDU to remove such software:  http://www.wagnardmobile.com/DDU/  

Reboot and manually download and install 16.8.3 graphics driver (don’t let auto installer from Windows do that)  You can find here:  http://support.amd.com/en-us/download/desktop/previous/detail?os=Windows%2010%20-%2064&rev=16.8.3
or
a newer version if you prefer … (but please do not use any driver from 16.9.1 ~ 16.12.1); here you can find listing of drivers … http://support.amd.com/en-us/download/desktop/previous?os=Windows%2010%20-%2064

 

After this done, just boot system.

It often works best by making a custom resolutoion for 3840×21060 at 60Hz with Timing Standard set to CVT-Reduced Blanking for use with TV and for use with Monitor you can leave that on “auto”.

I will ask [email protected] send you the latest firmware for the adapter as well.

To be able to use more than 2 screens from a HD 7750 card will require tha Eyefinity Feature to be activated.
You do that by
-using the DP output of the board (easy with this card)
-when connecting screen with DP input you can use “normal” or “passive” cables or adapters
-when connecting screen without DP input you need to use “active” adapters

So it should be like this:
Screen 1 : connect to Screen with “normal” or “passive” cables/adapters
Screen 2 : connect to Screen with “normal” or “passive” cables/adapters
Screen 3 : connect to Screen with “active” adapter with eyefinity support liek CAC-1070 + normal cable
Screen 4 : connect to Screen with “active” adapter with eyefinity support liek CAC-1070 + normal cable

CSV-5300H does not really have other limitations than the bandwidth.
So 3 x 2560×1080 60Hz will fit, becuase each video signal will be 4.98 big x 3 = 14,94 Gbps and that fits thrue singel DP1.2 ouput. So that will work.
Same goes for CSV-5400 …4 x 4.98 = 19.92 Gbps , that also fits over single DP1.2 ouput, so should also work.
Option 1 “Easiest” and option 2 “Best” both work and are correct.
Option 3 however i did make a mistake in … Dual Link DVI does support 2560×1600 60Hz, however that CAA-DMD>HFD3 adapter does not. So you would need a better adapter for that one.

I would say undo that scaling thing you did and start from scratch. I will ask [email protected] to send you latest firmware for the adapter to make sure that part is “fresh and ready” …

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 Bouzouki,

To be able to connect more than 2 screens to the HD 7800 you will need to “enable” the eyefinity feature.You do that by using 1 of the DP ouput of the Graphics card.
When you want to spread 1 video signal over the 4 screens (Single Large Surface or SLS) it become increasingly important to use the sames screens and also preferrably connect them in the same manner. If you chose to have individual video signals to each screen than that would still be nice, but less important.

A DP1.2 output has 21.6 Gbps of bandwidth.
A 2560×1080 60Hz signal in 8BPC takes 4.98 Gbps.

A few option you could choose from …

Easiest:
– MST HUB CSV-5300H = DP to 3 x HDMI
Connect with the Mini-DP to DP Adapter (standard incl in the box) to the Graphics card.
Screen 1: Connect screen to MST Hub with “normal/Passive”HDMI Cable
Screen 2: Connect screen to MST Hub with “normal/Passive”HDMI Cable
Screen 3: Connect screen to MST Hub with “normal/Passive”HDMI Cable
Screen 4: Connect screen to HDMI output on Graphics card directly with “normal/Passive HDMI Cable

“Best” (for SLS setup)
– MST HUB CSV-5400 = Dp to 4 x DP
Connect with the Mini-DP to DP Adpater (standard incl in the box) to the Graphics card.
Screen 1: Connect screen to MST Hub with Passive DP to HDMI converter CAC-1001
Screen 2: Connect screen to MST Hub with Passive DP to HDMI converter CAC-1001
Screen 3: Connect screen to MST Hub with Passive DP to HDMI converter CAC-1001
Screen 4: Connect screen to MST Hub with Passive DP to HDMI converter CAC-1001

Cheapest
Screen1: Connect screen to HDMI output on Graphics card directly
Screen2: Connect screen to DL DVI output on Graphics Card with Passive DVI to HDMI Adapter CAA-DMD>HFD3
Screen3: Connect screen to Mini-DP output on Graphics Card with Active Mini-Dp to HDMI Adapter with Eyefinity support, CAC-1170
Screen 4 : Connect screen to Mini-DP output on Graphics Card with passive Mini-Dp to HDMI Adapter, CAC-1101

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.
