[CentOS] Question driving external LCD from dell laptop

[Jerry Geis]

Bryan,

I have the Nvidia chipset. Geforce2 go.
Under XP I see a selection for "Nview display mode" and I select to try 
to find something that will show me refresh rates, scan rates etc...
but I dont see where that is.

Can you be more specific about how to view that information so
I attempt to duplicate that under X and CentOS.

THanks,

Jerry

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.
