I am currently running a dual boot of Ubuntu and Windows 7 on my Laptop and now I am trying to connect another monitor for work. The problem is that my monitor (LG W1952QT) works when I boot Ubuntu but does not display and goes right into powersave mode when I boot windows 7. Any suggestions would be greatly appreciated.

Is it a laptop? If so, remember to set the output mode to your digital video out. There's a button or fn-button to set it. Most laptops have 3-4 modes:

  1. built-in LCD
  2. S-Video out
  3. 15-pin (analog) out
  4. DVI/HDMI out

It's a lot easier to get dual monitors working in Windows than it is in Linux.

What happens if you plug it in after Windows has started? If nothing, try pressing the Windows + P.

  • Eh. xrandr is actually a really simple tool, once you wrap it with a little bit of Python ;)
