hi
not sure I understand your issue

If when you show the desktop on your pc, it looks fine, but when you play movies, they seem dim.
Perhaps you need to see if there is a way to change the brightness/contrast of the video overlay settings. On my nvidia card, there are separate settings for desktop and video material.

that is exactly what i mean mate

when viewing the pc using the projector
if i navigate through windows surf the web no problem nice and bright it is (well bright enough

but when viewing movies ethier downloaded 1's or dvd discs my projector goes dim

need help with this

Which program/player do u use to see the movies (windvd, zoom player)? Have you also set the proper resolution and frequency for your pc desktop?(you go to the ATI Catalyst control center and enable the same resolution like the one of your projector p.e 1280X720 on 50 Hz)

mate i use any player it all the same
power dvd/windows media 11/vlc player/nero showtime

where are these settings mate and can you devulge any more info

edit ok mate tried that still the priojector dims

maybe you need different settings on your projector for watching video, like turning up the gamma or disabling the iris, etc.

It sounds like an overlay problem as it only happens on video (which uses overlay). Find the graphic card overlay settings and tune the gamma / brightness.

thanks mate but i cant find anything like that
thing is the whole desktop will dim not just the video window

To see if its an overlay issue try this

1. Open Media Player. On the Tools menu, click Options. This will open the Options dialog box.
2. In the Options dialog box, click the Performance tab.
3. In the Video acceleration area, click the Advanced button.
4. In the Video Acceleration Settings dialog box, clear the check box for Use Overlays. (Its on video and DVD so play around)
5. Select OK and then OK again to close the dialog box.
6. Playback the video.
