I've just connected mine and after a bit of fiddling about managed to get the image to appear.

Haven't played too much with settings to improve this but after a quick look not sure if this is going to be possible.

Am I correct in thinking it will depend on the maximum resolution (1680 x 1050) of my external display or is there some other setting I need to be aware of as it is connected via a HDMI port?

Run my telly from lappy without problems. In fact it was just a case of plugging it in and it worked so can't even tell what the settings are. Movies, etc. run fine.

Telly is Samsung 42" plasma - series 5 or 6 seems to ring a bell.

Laptop is Dell XPS1330 - with the intel graphics (not the NVidia one) with HDMI out.

Beware though other people have reported that it is common for this laptop to fry itself - although, touch wood, mine has not.

Have played around quite a bit and managed to significantly improve the image.

The NVidia Control Panel software is a pain in the @rse!

When I logged onto the laptop this morning, it provided me with additional resolution settings that weren't there yesterday.

After playing around with the settings today and re-booting, those additional settings no longer appear in the NVidia Control Panel (fortunately, it has retained what I had set them to).
