CSV-5300H troubles

I’ve had a CSV-5300H for a couple years now, but I rarely use it because I didn’t realize until after I ordered it that I needed DP v1.2 with HBR2 & MST.  I now have a laptop with appropriate support (HP ZBook 15u G4) on the integrated graphics adapter, and I can’t seem to get it to work.  I have a variety of Samsung monitors at my disposal with DVI-D in, and my laptop detects the hub and the displays, but I can never seem to get an image to appear.  The monitors make it seem like they have something to display: one model has a solid LED like it has a connection on the DVI-D link, but doesn’t even kick on the backlight, and the other model switches between it’s VGA and DVI-D inputs like it doesn’t have signal, but it blacks out when it switches to the DVI-D link.  Using an Extron DP v1.1 active DP->HDMI adapter, both models show a desktop.  I have a sinking suspicion the CSV-5300H has had some sort of failure, but I’d like to try a firmware update if one is available, if nothing else.  Thanks!

Good day Andrew,

Most notebook have a limitation that they can only feed 3 screens at the same time including its own. So if you would want to connect 3 external screens, you most probably will need to disable the Notebook screen.
An MST Hub works as an active device, so you should connect screens with normal or “passive” cables or adapters to the MST Hub. So when connecting screen with DVI input use an adapter like CAC-HMD>DFD plus a normal DVI Cable (the adapter support single link DVI so max resolution of 1920×1200 60Hz).
Thsi one i dont understand: Using an Extron DP v1.1 active DP->HDMI adapter, both models show a desktop
If your screens have an HDMI input, why dont you just use a standard HDMI cable to connect to the MST HUB ?

I’m aware of the display limitation, and I’ve tried using the 5300H in several configurations, including one single display attached to the center HDMI connector on the 5300H.  I use passive HDMI->DVI-D adapters to connect to my monitors, as they only have DVI-D and VGA inputs.

All three monitors support 1920×1080@60Hz natively, and that’s the resolution I’m attempting to utilize.

The Extron adapter is being used in place of the 5300H; it is an example that one DisplayPort connection from my laptop to one DVI-D port (via an HDMI cable and an HDMI->DVI-D passive adapter) on any of the monitors I have will work without issue.  The Extron adapter is an active DisplayPort to HDMI adapter.  With that configuration working, if all I do is swap the 5300H in place of the Extron adapter, I lose video.  Windows still detects the hub and monitor, and I can select a resolution, but the monitor is blank.  If I hit the “Scan” button on the 5300H, it disconnects the monitor, then reconnects it, with the same blank/black/no-backlight screen.

Hi Andrew,

I have not heard of Samsung monitors not supporting MST feature. Sometimes you do manually need to enable DP1.2 support in the menue of the Screens. But if you only have DVi and VGA input that option is most probably not there.
We ahve heard more issue with HDMI to DVI Cables not working well in combination with MST Hubs and/or other active devices. This is why i suggested to use a  CAC-HMD>DFD to make sure the cables ar not the issue. Not saying the cables are no good and no disrespect, just could be they do not functioning well in combination with MST Hub.
And last but not least ther eis of course also a possibility that the MST Hub is defective. I don’t think that chance is big though becuase the system recongizes the screen when connected and it als o build up new connection after reset … but never say never … If you are convinced the CSV-5300H is no good, please claim warranty from the palce of purchase so they can arrange new product for you.

I started this thread under the impression that the device was failing… I just wanted to see if there was a firmware update or if I was missing something in the diagnostic process.  Unless there’s a generous warranty period, I imagine my 5300H is out of warranty.  We purchased it directly from a distributor, Synnex, in February of 2016.

Hi Andrew,

I will ask [email protected] to send you the latest available firmware for the CSV-5300H today.
Warranty for all Club3D Products is 2 years. Now it can be of course that have bought the product under diffrent terms from Synnex, so please check that, but warranty -wise you should be fine.

Thanks!  After trying the firmware upgrade (I was on 0.45), the updater gave an error that there wasn’t any boot code on the main device or P1, and P2 couldn’t be found or updated.  After updating the firmware on the main device and P1, I no longer get the boot code warning, but P2 still shows “Failed to get connection”.  Also after the update, I get video on each port, but I haven’t tried three externals yet.  Also, it appears to scrunch the 1920×1080 resolution horizontally and puts some garbage to the right of the image.  I will try to setup the RMA with Synnex this week.

Thanks, again!
