PC will not allow me to run higher than 1024x768 resolution

I have connected a large 42" TV to this PC as a wall board, the monitor will run at 1280x720 (16:9) but the maximum I can select is 1024x768 in the video settings. As far as I know it has the right driver, "Intel 82815 Graphics Controller) " Driver Version is 6.13.1.3198 - quite up to date I think.

I'm not sure where to start!

Thanks,
Andrew.

The TV will do much higher resolution than the 1280x720 I need, and yes its only a VGA 15-pin which if supported will obviously go upto 1900+ lines. I cant find the supported resolution so will have to find another card to put in the machine but I'm not sure if it is standard PCI.

I too have used large tv's in the past and at home on very high resolutions and am using a high quality VGA cable as discussed. I think there is a problem with the settings in XP recognising that the monitor will accept the higher resolution.
