I think I know the answer to this one, but I just wanted to make sure.

WHich projector would give the best picture on DVDs only - an SVGA DLP which did have a 16:9 mode, or an XGA DLP which did not. All other things being equal.

Thanks

I don't think your question is very relavent to resolution... SVGA=800x600, XGA=1024x768. Neither resolution is a 16:9 aspect ratio. A 16:9 "mode" on either type or projector will simply electronically "squish" or "stretch" (depending on the model) the image to fit in the middle of the panel to make it look right. An XGA projector is obviously a higher resolution, so it in theory will look better... but if it doesn't have a 16x9 mode you'll have to use an external scaler or HTPC to make the aspect ratio correct. The image quality will therefore depend on a number of factors, not wheter one projector is simply an SVGA with 16:9 mode versus an XGA. A SVGA unit with a good scaler can still look better than an XGA unit with a bad one...

What I actually meant was given that the hypothetical SVGA unit can take advantage of anamorphic discs and the hypothetical XGA unit cannot, would I be losing resolution from the DVD.

Ok, if the XGA unit doesn't have a 16:9 mode, then you'll have to use the letterboxed mode of your DVD player. I guess you can calculate the lines of resolution and see which is greater...

The SVGA projector will be receiving more detail from the source and should give you a more detailed picture. The XGA projector can have more detail but will not show it because it is not receiving the 33% gain in vertical resolution from the source.(All other things being equal)

I have demoed both VT540K (XGA) and VT440K (SVGA), the picture i saw is almost the same beetwen VT540K vs VT440K feeding with my Toshiba SD 3006. So i take VT440K.
