I have a dell inspiron 8200 laptop running centos 4.1 just fine. I want to connect it to an external 32 inch LCD. This laptop is dual boot windows. I set windows up to 1024x768 and connected the LCD - it worked just fine. LCD max is 1333x768 I then booted Centos 4.1 and set X to be 1024x768 also. rebooted the laptop just ot make sure. I then connected the LCD and it says can't display it... Any ideas on how I might get the LCD to display CentOS X?

Depends on the GPU chipset.

If it's an nVidia Go Mobile, you can use the nView features of the Standardware (Open Standard, Proprietary Source) drivers. It will let you set the _exact_ scan ranges of your 32" LCD TV (I assume it's a LCD TV, given the size/scan range), as well as the geometry for the 2nd head.

If it's an Intel i855G/915G, then I've had a real hissy fit with mine. I can't seem to get the i855G/915G to do anything under Linux except send the _exact_same_ scan rate as it's using for the LCD. E.g., on my Toshiba Satelitte M35 series, it sends the _exact_same_ scan rate out the miniDB15 as it uses for the LCD. I have _never_ seen that with any other notebook I've ever used with a non-i8xx/9xx GPU (they always send VESA-standard output signals).

So unless I don't know about some Intel tools out there for Linux, I hate'em. ;->

Never tried ATI Radeon Mobility.
