No display

[Tom B]

I have a Toshiba mobile LCD monitor model PA3923U-2LC3. My computer is a Dell 17 7737 with a GeForce 750M graphics card and Intel integrated graphics for external displays. I am running Windows 8.1 Pro.

I have uninstalled all DisplayLink software, run the cleaner, and reinstalled using the latest driver.

I can tell from the power button that the mobile monitor has power. When booting, the mobile monitor flashes with the Windows splash screen, then goes dark. Nothing I have tried will allow me to use the mobile monitor at all.

I ran the diagnosis software. It said everything passed. I have attached the log from the system information portion of the diagnosis software.

Any help will be greatly appreciated.

TIA
