I am trying to hook up linux to an LCD 1333x768 LCD TV. XP in 1024x768 show up just fine. X does not.
I have set the screen preferences to 1024x768. I have edited the xorf.conf file instead of have a range from 50 - 70 I change it to be only 60. I start X and it still comes up on my A70F monitor but still will not show on my LCD TV.
xvidtune does not run on this PC. It says something about "video modes are not tunable on this chip".
My PC at this time is a dell SC420.
Thanks for any input as to get the display working on the LCD TV under linux.

You also need to change the horizontal scan range. Changing the vertical will not do it.
Consider:
1. Open up the manual for the LCD and get the _exact_ vertical _and_ horizontal scan ranges.
2. Use the _exact_ scan ranges for VESA 1024x768@60Hz.
3. Booting Linux with the VESA 1024x768 framebuffer (e.g., vga=791 I believe?) and using that X server instead of the video card's driver.
#1 is most ideal. #2 is an option to explore only if you can't do #1. #3 should be a "last resort" (low performance)

Please don't tell me it's an Intel integrated video ... (I've had numerous scan range issues with such)

Yep, it is.

XP merely defaults to VESA modes. X11 tries to use the monitor at the most optimal rate by default, hence why your horizontal/vertical needs to be _exact_.

P.S. DVI solves most of these issues.
