I have a new HP Pavillion with Vista and an Infocus DLP. I am in sales and present off my laptop often. With my old Think Pad, I could view the laptop screen AND project the presentation with the Infocus DLP. This way, I can use the laptop screen as a sort of tele-prompter.
However, with the HP, I can only project the presentation with a dark laptop screen. If I enable the Vista control panle "Mobile" settings so I can see my laptop screen, the projected image becomes badly distorted. I tried changing the aspect ratio to 16:9 but thisw did not help. Any advice is appreciated.

Connect a separate monitor to your laptop and verify that your laptop's external monitor port is functioning properly.
If yes, connect and power up the LP120. Press the source key on keypad. You should see the projector switch from video to computer.
Last option, does the projector display an "out of range" message on the screen. If so, reduce your laptop resolution to 1024 x x768.
the colorwheel is collapsing and needs replacing. you can get one from any infocus authorized service centers and do it yourself or have them do it. if you are in ny, try av solutions. they've always done good work for me.
That is caused by a collapsing light pipe. This is a mirrored glass square component that is located directly behind the color wheel. It is comprised of 4 mirrored section approximately 40mm x 8mm that are glued together with a hi-temp adhesive to form a square. The artifact you see is one of these mirrored glass section's has come unglued and has moved inwards blocking one edge of the image. The edge of this shadow is not shar because this failure is not at a focal point.WHEW..all that being said it's possible to re-glue it if you are electro-mechanically savvy and have steady hands. If you need to take it to a service they will most likely just just replace the complete DLP engine (the whole optic assembly) Hold on to your wallet!!
if you are wanting to connect ur laptop to an external display then you have to go the control panel, then display properties and change the resolution since ur laptop screen's resolution and external display's resolution might be different. most of the computers with vista automatically adjust that but in xp, u might have to do it yourself.
A great deal of the time DVD players are very restrictive on outputting to multiple sources due to copyright protection. In my experience, if you use your laptops function keys to toggle output (For example, on my laptop, I hit FUNCTION + F4 to cycle between LCD,LCD+VGA,VGA), you should be able to disable the laptop's LCD display, only outputting via the VGA cable. It's worked for me with my HP VP6111 and Windows XP in the past.
Hope this helps!
