Hi Stacy, thanks for your note. Sorry about the trouble with the screen. Can you let me know:
1. Are you using the USB cable that came with the screen? (Longer cables can cause issues)
2. Are you connecting the unit directly to your computer and not through a USB hub (even a powered hub)?
3. If the answers to #1 and #2 are "yes" then can you try using a different USB cable, even if it is longer, and connecting directly to the computer (not to a hub)?
