Dell UltraSharp U3011 monitor goes to sleep and won't wakeup
I believe that I have read the existing posts to no avail regarding the UltraSharp u3011 monitor sleep mode problem.
My setup includes two external monitors: (1) a display port USB 3.0 connection to a StarTech DisplayLink plug and play module driving a Dell UltraSharp U3011 monitor, and (2) an older Dell 24" monitor (driven by a DisplayLink plugable USB 2.0 Display Adapter) these external monitors are attached to an ASUS N53SV-XR1 laptop (with 16GB RAM running Windows 7 Ultimate). This setup has worked for more than three years with no problems. The older 24" Dell monitor does not go into sleep mode. The U3011 is also connected to a Panasonic Blueray disk player using the HDM1 connector and there is no sleep mode problem when using the Blueray player. (I manually switch the U3011 between DisplayPort and HDMI modes.)
