Mimo UM-720S flickering problem @ Win7 :(

Hi,

i have a problem with my Mimo UM-720F (edit: not S) Display. Every time when i plug it into the PC or reconfigurate some display settings in windows the usb-display is flickering when it turns on. The flicker can be best seen on grey backgrounds. On white backgrounds it is not recognizable so its not the LED-backlight that flickers. The flickering gets better and better within about 3 minutes, then its completely gone.

The display starts flickering when:
- I restart the PC
- I change something at the display settings in Windows so the Display has to reinitialize itself
- I plug it in when it was not plugged in before since i startet the PC
- I send the PC to standby-mode and wake it up again (only @ win7 starter!)

However, the display DOESN'T start flickering when:
- I send the PC to standby-mode and wake it up again (only @ win7 home premium!)
- I send the PC to hibernate-mode and wake it up again
- I pull the disp off and plug it on again while the PC runs (doesn't matter how much time is in between)
- I turn the display off and later on again

Therefore it can only be an issue with the drivers, software, firmware but not an electronical problem because the previous points prove that the display IS able to start working without flickering after beeing off for a longer time.

I installed the latest Displaylink Drivers (5.6) but it had no effect. The flickering is extremely annoying because the display was destined for a car-pc.

Has anyone of you the same problems?
Please everyone that has NOT this problem, post anyway! It's a help for me to know if the display is damaged and this is a case of warranty.
