Dell Computer Duel display won't work

[MTUSUPPORT]

I was thinking this had already been tried.

I have a few systems that I have tested that have the 1 and 2 showing for Dual Monitors, but when you try to set the checkbox to extend the Desktop, it unchecks it and then the CRT monitor, clicks a few times. This is weird, but they are new ATI chips that are built on ASUS motherboards also. I was hoping they would work, but doesn't seem that it will.

Sounds like the old it better be BUILT BY ATI and not POWERED BY ATI still holds true

Can I ask if you have the 64mb version or 128mb the reason I ask is that the 64mb version of the x300 is not dual display only laptop screen or TV out

I have a Dell Latitude D-800 laptop and i had the same problem as you all desrcibe.

The problem seems to be the videocard and drivers not recognizing the TV/monitor/projector installed.

If you get the same view on both screens like a copy of your current desktop then you need to read the manual for the video card to fix that, I know there is a way to fix it and its all located under properties for the videocard. (The driver and software package from the videocard producer has an option for selecting what is displayed on the 2'nd view.)

If you do not get the video 2'nd view up at all like the problem i had, then disconnect all cables from your 2'nd TV/monitor or projector and hoock it up with a Scart adapter to PHONO plugs, and do not use the S-video mode, use the phonoplug if u have one. Then connect ONLY one screen at first, go into display properties, and first off "recognize" monitors button (in XP).
Then you activate the extention of desktop, and it should be working.

I had quite some problems getting this to work, and it even now sometimes fails to get extended. Then i turn off the computer, restart TV/Monitor/Projector and keep it turned ON while booting winXP then it should automaticaly detect your dualview and it should be activated when bootup is finished.

If this does not work, try changing videocards, or updating the drivers.

Kind regards,
