Here's a problem I'm having on my machine. I have 4
SIIG USB2.0 to VGA Pro External Video Card Display adapters (Chipset: DisplayLink DL-165) hooked up to my machine. With only three connected, everything works just fine - when I connect the 4th (it doesn't matter which three or which one I use as the 4th) two of the displays go down to 640 x 480 and cannot be changed without messing up ALL the displays (other displays with change resolution, all displays will rearrange, all icons and programs with rearrange across displays).
I have tried different USB ports (currently each display is connected to it's own USB channel on the mainboard), I've tried uninstalling/reinstalling, I've gone through all the troubleshooting steps - and nothing will enable me to make this work.
DisplayLink Core Software (7.7.59503.0)
DisplayLink Graphics (7.7.59586.0)
Here's my configuration:
- Acer 1920 x 1080 - connected to internal video card
- Acer 1920 x 1080 - USB
- Dell 1280 x 1024 - USB
- Dell 1280 x 1024 - USB (Stuck in 640 x 480)
- Dell 1280 x 1024 - USB (Stuck in 640 x 480)
I've attached the support file to this post.
