Complete Failure

Bob Cohen · 07-22-2010, 06:15 PM

Here's my configuration:

Sony VPC-Z1190X laptop:
nVidia 330M
Intel
Sony-proprietary auto switching facility
Windows 7 Professional, 64-bits

Configuration 1:
HP 24" 1920X1200 direct connect to laptop
2x Gateway 24" 1920X1200 via Winstars devices (WS-UGA19D1)
Connected directly into Sony docking station

Configuration 2:
Samsung 21" 1920X1080 direct connect to laptop
3x Samsung 21" 1920X1080 via Winstars devices (WS-UGA19D1)
Connected into powered 7-port hub connected into Sony docking station

Here's the scenario:
Configuration 1 always works from a fresh reboot.

Configuration 2 has worked in the past but required fiddling with the USB connections such as unplugging/replugging/rebooting.

Today, however, I can no longer get the screens to operate at all. The drivers are seen by Windows, but not the screens. Nor are the LEDs on the adapters blinking. A complete washout.
I have uninstalled the drivers (and deleted the files), reinstalled, etc. nothing working.

I've spent all morning on this and am about to give up altogether. I will be forced to install a desktop machine for configuration 2 and just drive the monitors with actual video cards.

Any suggestions before I have to abandon all of this???

Thx,
Bob

Followup:

It turns out that when I said that I uninstalled/reinstalled the driver, I did so from within Device Manager. I specifically told it to delete the driver files themselves as well.

Then I decided to try from the Control Panel (Programs and Features). That actually worked.

After reinstalling and a couple of reboots (black screens, etc.), it now seems to be working.
