Troubleshooting: Hardware Failure?

I had yesterday a similar problem. The device did not show a black screen but it was incredibly slow at rendering, which usually is a symptom of USB connection failures.
This was all sudden. For me it's easier to debug because we have so many devices lying around to try.

The story ended well because I have been forced to swap the unit for a USB3 one and I have to say the performance improvement on my 1920x1200 screen is noticeable. Probably because of the improved compression in our DL-3000 family more than the added bandwidth: the improvement is visible even with a USB 2 cable.

For this kind of sudden issues without any SW change the advice is to try a fresh driver installation, also on a Windows computer if you have access to one, and if the problem persists contact the manufacturer for a replacement.

It's a good idea to let us know in the forum or support contacts so we can inform the manufacturer of the problem.

Cheers,
Carlo
