Do any Barco Data 801s have built in line doublers? mine has such a great picture, it looks like it might. I wonder what a progressive scan DVD signal would look like.

I just got the Kenwood test DVD, on the chapter with the flag flying, I can see no jaggies in the edges of the stripes while it is flapping in the air, that's why I asked the question.


Thanks Bill

Internal line-doubler in 801s? NO!


Just toggle the TEXT button and you will show what scan-rate the projector operates on. If it is 15khz then the projector is feed with standard interlaced video.

How big's the screen?


If it's over ~40 inches wide (which it most likely is!) and you DON'T see individual scan lines running at 15Khz NTSC, something is horrendously wrong with the installation and/or focus!

A well-set-up 801s will clearly resolve the scan lines of a line-doubled source as well. The optimum feed for an 801s is probably around 720p (tripled).

When pressing the text button, the box displays

15.7Khz

60hz


This is meaningless to me, The picture is about 7.5' Diagonally.

It is focused correctly, and I can see scan lines in most material if I get close to the screen. I compared what I see to what I see on a $17,000 Sanyo LCD projector at work using the same material, there is no comparison, the Barco blows it away. If my unit does not have a line doubler in it, then I don't think I need one.

15.7Khz/60Hz is a regular non line-doubled signal. The same signal every 'regular' TV uses. You're seeing an image that made up of 480 lines (and interlaced).


You should be seeing scan lines from *VERY* far away, not only close to the screen. If you don't see scan lines from 15-20 feet back then something is very wrong.


This projector's cable of much much more..... you're just scratching the surface.
