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

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.

So i think i am a gluton for pain and went back in to see what i could learn. I managed to get one of the hubs 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?

Got the new hub. Same results. Any ideas?

Thanks. I have a replacement coming tomorrow and will post the outcome.

Edit for redundant post

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?
