I have a laptop that i use to run my xga native lcd projector. The laptop is a widescreen 16:9 laptop running windows xp. The laptop is set to 1024 x 768 resolution but looking at the image on the laptop screen(not projector) the image is stretched horizontally including all the letters. At the same time the desktop image seen on the wall (image of projector) is fine no stretching.
However when i use dvd software like powerdvd and go to full screen i get horrible image. What looks like blocks around the pixels. I assume some lousy scaling attempt by the dvd software?
What can i do to fix this? Is this a dvd sofware issue? Do I need to reconfigure the laptop to a different resolution?

1024 is not a widescreen resolution. You would need to set it so that your internal laptop screen is at a widescreen res (depending upon what your laptop supports) and since your projector is not widescreen, but is instead 4:3, you need to set that output at 1024x768 or another 4:3 res that it supports.
Your internal LCD is stretched is because of the fact that you are displaying a 4:3 res on a 16:9 screen.
Your projector is 4:3 (xga is 1024x768), and that's why it does not look stretched, because it isn't.
You also don't say where the DVD looks awful, is it on the internal screen, or on the PJ?

Thanks for your input. The dvd looks awful on both the laptop screen and projection image in full screen mode. Ok so you are saying set the windows resolution to a widescreen resolution such as 1280 x 768 for instance. But what happens with the projection resolution. In order for the best image on the projector i must feed it native res of 1024 x 768.
Is seems like it would be better to set the laptop to 1024 x 768 res but configure it to a 4:3 image centered on the laptop screen. Another words I should have a 4: 3 image on the laptop screen with black bars on left and right. Is this possible? Whould this be the best solution?
I think what I would do, since the internal screen is a different aspect ratio than the external screen, is try to set them to different resolutions. There are a number of ways to do that, depending upon the abilities of the laptop, video chip, etc. If the laptop can't have separate modes for the internal and external screens, then I would do what you are doing now, and keep it at 1024x768.
As far as DVDs looking bad, maybe in fullscreen mode, your player is doing something strange with it, like somehow setting it to an aspect ratio that isn't appropriate for the screen it's being displayed on?
Check the setting in your DVD player app, and see if you can set it to maintain the aspect ratio of the dvd, or change the aspect ratio to the correct one.

ok. i will check the dvd player aspect settings. Where does the laptop have this option for internal and external screen resolution settings? Is it in bios or windows?
