Apologies if this has been covered before -- tried searching but did not find.
I have an R60 9456-57U with the Intel 945GM graphics chipset. I would like to attach an external LCD monitor via the VGA port and run it at its native 1920 x 1080 resolution, but I am having no success. The short version of the story:
I started out with the 22.214.171.12460 version of the Intel driver. If I unchecked "show only modes the monitor supports" it let me select 1920 x 1080 but the display was jittery. (All other modes were okay in that regard but had the usual problems of an LCD not at native resolution.)
I downloaded and installed the 126.96.36.19926 version of the driver. Now it will not even let me select 1920 x 1080, even though the Intel "Information" diagnostics.txt shows it as a supported mode of the monitor.
Any suggestions? Thanks in advance,
Solved! Go to Solution.

The intel driver doesn't really support the 16:9 resolution, their driver support is really poor.

Intel support seems pretty good. My *hunch* is that the problem is that the Lenovo video BIOS prohibits wide-screen modes. Intel is continuing to work on the problem.
I took a look at http://forum.thinkpads.com/viewtopic.php?t=22248 but that approach looks a little too scary for me. Rolling back the driver every time I want to use the built-in screen? I don't think so.

i have a HP with the GMA950 Intel and it doesn't support widescreen in 16:9 either, nor does my friend's Dell Latitude with the same integrated GPU. Maybe Intel have an excellent driver, but i am not able to see it or use it.

Following up on my video BIOS hunch, I tracked down this http://www-307.ibm.com/pc/support/site.wss/MIGR-64579.html and thought the change for 1.05 sounded promising. I re-flashed the BIOS and voila! The video properties now offers a bunch of "wide screen" choices and when I selected 1920x1080, the monitor looks perfect.
