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.

Start by looking on the graphics card manufactuer website to see what the supported resolution is.

Probably 1024x768 is the maximum settinsg for that graphics card.

Hope this helps

The problem is going to be that 1024 x 768 is the maximum resolution of the 42" TV

If you have HDMI Inputs you could get a DVI to HDMI and possibly get a higher resolution but if you are just using 15 pin video cables you will be stuck with this resolution.

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.

There is only certain resolutions that your panel will except through the VGA cable. The manual lists all the resolutions that the panel will show (probably max of 1024 x 768

You can only get 1920x1080 resolition via HDMI.

How long is the VGA cable you're using? If its too long and not a high quality(expensive) cable then it will be limited to 1024x768.

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.
