Well, the 1080i is a resolution of 1920X1080 and the 720p has a resolution of 1280X720. Just change the resolution to any of those settings and you will be viewing a HD picture on your HDTV. You will need to download a high defenition video in order to view a video at a HDTV resolution. www.wmvhd.com has some samples and I am sure there are some new h.264 HD QuickTime samples on the internet as well. You can slo set a game to any one of those resolutions and it on your TV.
The Dell drivers (72.01 & 77.24) wouldn't let me add the plasma's native resolution in PowerStrip. When I installed the 77.77 drivers from laptopvideo2go, I could add a custom resolution that is close to the plasma's native resolution, but I lost the ability to have the desktop appear on the plasma when I turn on the PC in single display mode, even though the plasma is the primary display. I always have to switch over using Fn+F8.
well, it seems when I connect my laptop to my plasma, I can only set resolution for ONE screen and it just doesn't work. when I use dual screen, the mouse cursor moves over from the first to the next, but I can't choose different resolutions for different screens. A step by step guide would be very helpful.
