Application not Starting in Windows 8.1

[sikcool]

So I'm running x64bit of Windows 8.1 and trying to use Cable Matters' USB 3.0 to HDMI. I installed v7.6M1 and restarted but I don't see the application icon in the tray at all. I went to the

C:\Program Files\DisplayLink Core Software

and tried running

DisplayLinkUI.exe

but nothing happens.

I ran the support tool and this was the message:

Pass: Basic mode support
Pass: Device attached
Pass: Device started correctly
Pass: Graphics driver date
Pass: WEI is above recommended 3
Pass: No Other USB graphics software installed

So the device is all connected and everything but I am not able to get it to work. Any ideas what the problem is?

Hi,

Can you try the following:

1. Disconnect your adapter
2. Uninstall DisplayLink software
3. Download and run this tool http://www.displaylink.com/support/ticket.php?id=297
4. Install DisplayLink software
5. Reconnect your adapter

Thanks,

So I got to 4. Install DisplayLink software and it doesn't really look like anything got installed but when I try to run it again it says:

DisplayLink Software for DisplayLink Graphics is already up to date

But I don't see any programs in the tray so I can't open any software up. But I went onto step 5 anyway and plugged in my adapter into the computer then plugged in a HDMI cord from the TV into the adapter but the TV doesn't detect anything and neither does the computer. So we're back to square 1.

The main problem is that nothing seems to get installed when I run the installer even though it shows up as installed in the control panel, it makes a folder in Program Files, and it gives the above error message if you try to run it again.

Hi,

I've taken another look at this.

The logs tell me that a monitor / TV has not been detected.

This is why you're not seeing the taskbar based UI run.

Can you try a different video cable and other video ports on the monitor / TV?

Thanks,
James

I initially had the USB-to-HDMI adapter plugged into a USB 3.0 hub I had plugged in. So this time I tried plugging the adapter into the motherboard's USB 3.0 I/O ports directly. The USB adapter had a green light inside of it that turned on signifying that it is receiving power and also I can see on the device manager that it recognizes it. I have a screenshot of the device manager below:



I've tried all the USB 3.0 ports in the back of the computer and still no luck. The only thing I can think of is that my Gigabyte motherboard has an onboard video card (HD4600 Intel) that I disabled in the BIOS because I have an offboard NVIDIA 9500GT card that was causing problems when booting up. Basically, the computer did not like have 2 video cards active so I disabled one.

I don't know if that is the cause of any of the problems but I really can't think of any other reason.

Any thoughts?

Edit: The green light from the adapter does not persist. When I plug it into a USB 3.0 port it blinks green for a second and then goes away. The device manager still lists it but I don't know if the adapter is broken or not.

Hi,

Have you been able to try my suggestions above about other video cables / video ports?

Thanks,
James

Yes, I've tried all the USB 3.0 ports on the hub and all the ports directly on the desktop. None of them work.

Have you tried a different display and video cable? The logs show that no monitor is being detected, which is why you don't see the DisplayLink icon in the tray or any display output.
