Is club3d csv-7200h (dp1.4 to two hdmi) a good quality mst hub?
my ultimate plan is to use 2x 6900xts and run 12 4k HDR projectors, 6 from each gpu .(3 club3d csv-7200h s on each.)
from what I gathered online so far this is doable, any caveats I should be aware of ?
one side note: I’m planing to use the mst hub with 30m HDMI cables can I expect the signal quality out of the mst hub to have enough strength to reliably drive the projectors.
Active cables, repeaters, etc.
Card should have the bandwidth. Would need a type C adapter of some kind. Unless certain models have 3 DP connections.
I could theorize about incompatibillities, but they’d just be theories with no real world examples.
Are you trying to mirror or have independent displays? Can a 6900xts support 6 independent displays? I think it only supports 4 screens per card, like you can use MST to convert 2 DP ports to 4 displays, but not 5 or more. Some sort of internal, possibly hardware limitation.
If there’s such a limitation, it’s software/artificial segmentation bullshit. Type C supports a certain revision of Displaport, since… I think DP 1.2, MST is part of the standard. On paper, and by the spec, it’ll work.
MST Hubs Video Card Limitations (startech.com) is one of the mentions I saw talking about this and another that I can’t find now that said nvidia/amd have a 4 display limit on most cards and intel has 3 (at least for igpu, this was pre-ARC), whether it’s driver or hardware based there didn’t seem to be an easy work around. This didn’t affect mirroring only extending the display.
6 displays are the per card eyefinity limit.
here is asrock 5700xt taichi which supports 6 4k displays out of the box.
I’m assuming the eyefinity limit is the card total dispaly output limit aswell, however I have read here and there that you can drive more than 6 displays per card but not on eyefinity mode. (even then eyefinity on crossfire supports 8 displays assuming you connect all displays to a single card, a single card can in theory support 8 displays.)
