CSV-5300A “No signal” when monitors connected

When I connect monitors to the mst hub, they get detected but no signal comes through. After a few seconds they go to standby mode. Interestingly though, both Catalyst control center and windows show the displays correctly detected in their respective display menus and CCC shows them in its displayport area as well where it shows the dp bandwidth being used by each. However, while none of the displays are getting a signal, if I connect remotely to the computer to verify this, the remote desktop acts as if all monitors are working and has extended the desktop over all of the space they would display.

I have tried: deleting and reinstalling the drivers per all methods I have found on this forum, power cycling both the computer and the hub, verifying the cables work individually connected to the graphics card via the mini dp to dp adapter provided as well as another adapter, trying just one monitor, two monitors, and all monitors, verified working both mini dp outputs on graphics card.

Finally, I did notice that when I try to plug a monitor into each displayport out on the graphics card at the same time (2 monitors total), the second one will not be detected at all. I don’t know what this could mean or if it is related. I have never noticed before as I used just 1 dp and 2 dvi outs prior to getting the mst hub.

Any help would be greatly appreciated as I would really like this to work.

Specs:

CSV-5300A: REV A1-2.1, FW 0.45, 1510, S/N 60201503100087
3x Cable Matters DP to DVI-D dual-link 6ft cables: SKU 102004 black
3x Acer G276HL 1920×1080 @ 60hz monitors
MSI R9 270x – 15.10 x64 beta drivers (tried 15.9 beta as well)
MSI Z87 – GD65 Gaming motherboard (most recent BIOS)
Windows 10 Pro x64

Hi “MadKow”,
Sorry to hear you are having issues.
It is not a good sing that you odnt get a picture form the seocnd Mini DP Output. What R9 270X do you have btw, is it a MSI R9 270X ITX version ?
It can happen that Catalyst will automatically place the resolution in some Ultra High Setting because it detects 2 screens.
We did not complete testing with the Beta drivers, so i will advise you to use the 15.7.1 WHQL.

Connect the MST Hub to the DP Output you now works and only attache 1 screen to the MST Hub and boot up the system. Check in Windows if all is ok. Only then connect the second screen, check in windows if all is ok, sometimes you will need to activate it first and most important check the resolution and frequency. Only than go for the 3rd screen, repeat the same windows check. When done go tot the Catalyst and setup your Eyefinity group etc. Don’t forget to make a preset (left top) when your done with the settings, very handy to go back to your preset-settings when needed with just 1 click

Hi,
If the second DP port of the card connected directly to the monitors does not work either the driver or our windows installation is providing issues. There is also a possibility that graphics card is having issues.
As the MST Hub is a portable device, please check if you can have it tested in a different system.
Based on your feedback, it should work. 

Kind regards

Thanks for your replies. All to no avail I am afraid.

I tried the steps provided. Am now on 15.7.1 drivers as well. No matter what is connected to the hub, I still get no signal.

The desktop is still being rendered when i log in remotely, monitor is detected in both catalyst and windows, resolution and refresh are correct, displayport diagnostics in ccc show the monitor, but still no signal. I even tried hooking up my old samsung syncmaster to it and that works with adapter to dp but not through hub either.

Note: I was incorrect on the graphics card. It is XFX R9 270x. Also, I was able to get both displayport outs working simultaneously and both separately when going directly to the monitors, so they are not the issue.

Any more thoughts?

Hi,
I think it probably is the MST that could be defective in this case. Please exchange it for a new one.
Kind regards

So i think i am a gluton for pain and went back in to see what i could learn. I managed to get the hub working with a single monitor. My old syncmaster 226cw. But only part way. The system (both windows display settings ans catalyst cc) says the resolution is 1680×1050 but there is a black bar on the right side of the display of unused pixels and when i use the menu on the actual monitor it says the resolution it is receiving from the computer is 1809×1053 60hz. So the black bar is the extra 130ish pixels width the monitor is being told by something to display, but the windows/ccc are only using the now squished 1680. The native resolution is 1680×1050.

I have tried changing resolutions. These will change without removing the black bar (and the output from the computer detected by the monitor firmware still says 1809×1053. I have tried reinstalling drivers, power cycling, detecting monitors, hitting the scan button on the hub.

When i plug the monitor directly into the computer dp using the mini dp to dp adapter from the hub and the same dp to dvi adapter i was using to the monitor, it is recognized fine with the correct resolutions and refresh in both windows and the monitor firmware menu.

I think this may be why the acer monitors are saying no signal. If they are being sent an incompatible resolution they may not be taking the signal at all.

Any ideas?

Can  you test the Power Adapter that comes with the MST Hub ? Or try a different one that oputputs 5Volt and 2.4 Ampere …

I used both adapters with the same results. I got a replacement drop shipped so I have two complete packages to work with. Both gave the same result.

Any other ideas before I just send them back for a refund? I am out of ideas.

Can you check with Acre if the screens are capable of receiving MST signal ? This would normally not be an issue with screens with a DP input … but just to be sure …

Hi, I am Luis from Madrid (Spain).
I am looking for a way to connect 5 VGA monitors (with his VGA cables, some of them with 7 m) for using only with Microsoft office. Is this possible with a CSV-5300 – MST 1-3 DP Hub + an AMD Graphic card + transitions DP, HDMI and DVI to VGA?
In this case, which CSV-5300 and which AMP have I to choose?
Best regards

Hi Luis,

The easiest way to connect 5 screens to 1 pc is with this Graphics Card; CGAX-7856M6. 
http://www.dynos.es/tienda/search.html?key=cgax-7856m6&f=

This card has 6 mini-displayport outputs and you can connect 6 screens to that.
When using Screens with DP input you can use “normal” or “passive” cables, when using screens with other inputs you will need Active Adapter Cables for every monitor apart from the first 2 you connect.
Note: Cables USB/DP/HDMI will loose singal quality after 3 meters and you might need active cables for cables longer than that.
For Screens with VGA input you will need : CAC-1102 = Mini-DP to VGA Active

Please check for available screen configurations:
