AOC E2251FWU USB monitor flashing
I have a mid-2013 MacBook Air running Mountain Lion. Upgraded to Mavericks, lost multi-monitor support, rolled back to Mountain Lion.
I can successfully attach to my Toshiba Dynadock 3.0 with dual monitors via a USB cable, Lenovo LT1421 portable USB monitor as an extended desktop, and Samsung LCD TV as a mirrored display. I used to be able to use the AOC E2251FWU portable monitor. Starting around mid-summer, when I connect, the MBA screen and the portable monitor turn on and off without success. I think this was due to an Apple software or firmware update. I have checked the power settings, and tried setting to never turn off the screen, no change. I tried rolling back the DisplayLink driver from 2.2 to 2.1, no change. I tried plugging the monitor into both USB ports, no change. I tried from BootCamp with Windows 7, no change. I tried on my old Toshiba laptop running Windows 7, and it works no problem. What can I try next? Last edited by scottm; 10-01-2014 at 03:46 PM. |
