CentOS 4.4 Kernel Release 2.6.9-42.0.3.EL Monitor: ViewSonic VX1935WM Video Adapter: Intel 82945 G Express KDE 3.3
Greetings
I am attempting to configure my ViewSonic VX1935WM widescreen monitor. Unfortunately this model is not listed in the Display Settings. I have attempted the generic 1440 x 900 LCD monitor listed. This does not provide the required resolution. I have edited /etc/X11/xorg.conf and added my monitor, resolution, refresh rate, and screen size. The problem is that even when I have added this to xorg.conf the new resolution does not show in Display Settings and I cannot change my display to the new resolution.
Can anyone point me in the right direction?
Thank you

I could be wrong, but that sounds like a video card driver issue. If the display properties aren't showing the required resolution either the card is incapable or the driver hasn't been written to properly support the modes of the card.

That was my first thought but I am dual-booting to Windows XP Pro and 1440x900 is available in Windows. So if it is the case as you suggest, then how can it work in Windows?

You're not using the windows device drivers in linux however. Please avoid comparing apples to chickens.
I have a monitor similar to this (the Viewsonic VX2025wm) and a graphics card capable of handling the widescreen resolution. The changes I needed to make to /etc/X11/xorg.conf were as follows:
Section "Monitor" Identifier "Monitor0" VendorName "ViewSonic" ModelName "ViewSonic VX2025wm" HorizSync 30.0 - 82.0 VertRefresh 50.0 - 85.0 Option "dpms" EndSection
Section "Screen" Identifier "Screen0" Device "Videocard0" Monitor "Monitor0" DefaultDepth 16 SubSection "Display" Viewport 0 0 Depth 16 Modes "1680x1050" "1280x1024" "1280x960" "1152x864" "1024x768" "800x600" "640x480" EndSubSection EndSection
Note that I'm using an nvidia card with their proprietary drivers, and have no problems at all with this screen. I'm actually considering getting a second one and going dual-head with it.

That's because under Windows, you are using Windows driver. Under Linux you are using xorg driver. Different code, different capabilities.
See my previous reply to your question on how to get your Intel based video chip to display 1440x900 under Linux.

It's video card dependant. X server doesn't support resolutions not in VESA BIOS out of the box (at least for some video cards). Wide screen resolutions are usually not listed in VESA BIOS by default. For Intel video cards, there's couple of programs you can try to change one of the VESA BIOS modes to 1440x900 (you'll need to do this on every boot, before X server starts). For example 915resolution (available from Dag's repository) should do it for Intel 800/900 chipsets.
I've got an ACER AL1916W and suffered the same issues...
I can't recall how I got the orginal config - but I remember useing an x utility to generate a config based on my screen size and refresh rate...
Anyway: I keep emailing myself the xorg.conf so as not to lose it!
I'm attaching it here for you - hope it helps.
I use an old ATI - Rage card - but just change your drive to 'intel' and it will work (I've done the same w/ my widescreen on a Dell Dimension at work. (FC4)
I run FC6 here.
