I found the thread "915GM with 1920x1200, possible?" (http://software.intel.com/en-us/forums/showthread.php?t=57374) where instructions were provided for how to get a 915GM chipset to drive a 1920x1200 monitor, but I didn't understand the instructions, and a link with the information about how to make the changes in the igxp32.inf file was broken.
I may have posted this thread too soon. I just noticed the sticky thread at the top of this forum:Custom Resolutions for Intel Graphics: Made Easier. I'm reading it now, will post again later.
--Ted Okay, I've skimmed that thread. I know so little about graphics that I understood very little of it. I'll give it a much more careful read if I have to, but if someone already knows how to get 1920x1200 out of a T43 then help would be greatly appreciated.
--Ted After reading the sticky thread in detail and following it scrupulously I was able to get my T43 to drive 1918x1200. It can be done. Life is good. --Ted
