I have a question regarding obtaining the above resolution on my Barco Data 800. It is my understanding that I can not get 960p from it on a 4:3 screen. If that is true then how can the projector produce 720p on a 16:9 screen when 720p is what a widecreen dvd will be displaying on a 4:3 screen at 960p? Thanks for the help.

I think the 800s scan high enough for 1024x768 resolution, so if you compress the raster to 16x9, it can still scan to 768p. It's scanning that many lines, you just aren't using as much of the phosphor area.

Exactly whta neil525 just said. :)


950p in a 4:3 configuration will scan 960 lines onto the CRT face, and the projector cannot handle this high of a sync rate.


720p in a 16:9 configuration when displayed as a 4:3 image (using letterboxing) does in fact use 960 lines on the CRT face, with 240 of them blank. This is also too high of a sync rate.


720p in 16:9 using vertical squeezing at the projector (decrease the vertical size control in the geometry menu until the 4:3 720p anamorphic image fits your screen vertically) only draws 720 lines on the CRT face, with no blanks. This is within the 800's scan range.


When you play a widescreen (anamorphic) DVD, the DVD player will output a distorted image (stretched too tall) which fills a 4:3 frame. The Barco will compress it down vertically to appear correct again.
