Laptops connected to widescreen LCDs (Intel 82555 chipset)

Threaded View

I have a Dell 2405FPW widescreen LCD that has a native resolution of
1920x1200.  I've been trying to get it to work (at the native resolution)
with a Sony VAIO VGN-T150P laptop running Windows XP, which has an Intel
82555GME graphics chipset.  Unfortunately, while the Intel graphics driver
is clearly aware of the LCD's 1920x1200 resolution (one can view a report of
all the resolutions a monitor claims to support), 1600x1200 is the highest
resolution the driver is willing to offer for operation.

I've done some poking around the web, and what I've come to believe is that,
while the 82555GME can easily generate a 1920x1200 display, the Intel driver
only offers up resolutions that are specifically hardcoded into the video
BIOS, and -- at leas ton a VGN-T150P -- 1920x1200 isn't one of them.  The
Intel driver (unlike those from nVidia and ATI) doesn't support "custom
resolutions," so one can't use a program such as Powerstrip to generate the
new resolution either.

Interestingly enough, Dell's only Inspiron 700m laptop -- which uses the
exact same chipset and the exact same Intel driver, just a different video
BIOS -- DOES support the 1920x1200 resolution natively.  Grrrr!

So, my question is... does anyone know how to get native resolution from a
setup such as mine?  Or am I just out of luck unless I get a new laptop?

I presume your mean Intel 852/855GME, no? In any event, if you don't
have the latest graphics driver, it may be worth a try, just in case it
does what you need., etc., and it's pretty easy to follow
the steps.
