    Heres the deal. Dell 9400 with GeForce 7800. Happily outputs to projectors and monitors for a year. Then all of a sudden dosen't want to talk to projectors.

    4 different projectors in the school and none will work properly. If I fiddle around with the settings (refresh rate and res) I can get an image on two of the projectors but there is still distortion.

    The laptop outputs to LCD and CRT screens fine, just not projectors!!!! However I can't set the resolution and refresh rate when the screen in cloned.

    Has anyone come across this before. The card dosen't seem to be picking up monitor information (max refresh rate etc.) I know it is not a software issue as I have rebuilt the system and it affects Ubuntu and XP (both had been working fine)

    I fear if i send it back Dell will test it on a monitor and say it is ok. AHHHHH!

    Hmm that is very unusual.

    Not sure really what can be done it sounds like a software problem but as you say formatted and two different OS's both affected.

    Is the cooler still working on the card it runs at lower clocks in 2D mode but if the cooler had failed or was slowing down it would still possibly work but have unpredictable side effects.

    Try clearing the CMOS if that option is present on the Dell motherboard.

    Have you tried updating the drivers worth a shot anyway.

    You could try using Powerstrip to try and force the detection/resolution of the projectors.
