Screen randomly turning on and off

[smidgen11]

Im currently running win7 64bit and am having trouble keeping my 3rd screen on running off of the USB adaptor. I have a docking station on my laptop which runs my primary monitor. The 3rd screen is on the USB device and will randomly turn on and off. Windows shows the screen as disabled and over time it will randomly turn back on. I cannot reproduce the problem as it is random. Ive tried all the drivers on the site as well as the beta driver. nothing seems to fix this. i ran the advanced logging and attached it here. let me know if anyone has any ideas...
