7 Screens(1920*600) with 45º rotation from single GPU

Hello,

I’m trying to build a setup to feed a videowall with 7 screens from a single GPU(Quad P620 V2)

My first aproach was to connect 3 screens directly to GPU and 4 screens to a hubMST (mDP to 4x DP Multi Monitor Adapter/MST - DisplayPort & Mini DisplayPort Adapters | StarTech.com Sweden) but i only achieve to feed 4 screens. The other 3 apears connected on Windows but without resolution and unavailable.

Maybe it’s GPU max screens suported limitation, i thought the hubMST was seen by the GPU as a single screen but it’s not after all :confused:

Maybe using a QuadHead2Go it may works, is the QuadHead2Go seen by the GPU as a single out/screen?

Any advices for this setup?

Thanks

not all MSTs are created equal, some eat up two nvidia displays. I’d look into video wall controllers, an AJA box, or the “pro” solution, a datapath

You should use these: https://www.datapath.co.uk/datapath-products/video-wall-controllers/datapath-fx4/

I would suggest staying away from the QuadHead2Go. Some people like them but I’ve had many bad experiences with them in the past.

Thanks for the input’s, will look on the video wall controllers and the rest of the solutions.

With the solution using the FX4 can we define the input/output resolution?
Example:
If i feed the FX4 from TD with 3840x1200. in the outs can i get 1920x600(resolution of the screens)?

Was reading the docs from fx4 and cant find this kinda info about resolutions suported :confused:
@matthewwachter @drmbt anyone with experience with FX4, cant we get 1920x600 in the outputs.

Another solution using a NVS810 (https://www.pny.com/nvidia-nvs-810-for-8-dp-displays) if i can find this product still in sales.

Thanks will keep digging

Yeah I think you can. We’ve done some pretty strange resolutions coming out of those units. I think it will let you capture the EDID and even edit it if you desire.

I have done something with 2x 1080tis and an SLI although I don’t think the SLI is really needed. Might be cheaper than a data path at this point.
