A bit of a newbie question here, please bear with me .

I have a Barco 801s with 2000hr tubes, very little wear. It used to have a 4:3 setup at the former owner. I have used it a little bit just as a floor mount and just reduced video height with the remote to achieve 16:9 aspect as I use it for movies (1280x720@70Hz). Is this a bad thing to do? I mean is it better to actually adjust the raster height using trimpots? Would I get more scanline resolution like that? I'm a bit confused with the raster / video size thing.

I guess my question in condensed form is:

What is the best procedure to set up a Barco 801s for 16:9 aspect?

Any help greatly appreciated.

Edit: I forgot to mention I have read all setup guides here, but i didn't manage to distill this info.

Your doing it correctly.

For 2.4 aspect movies if you have a PC you can try 800p as that is all of the 1080p a 2.4 aspect movie actually uses
as the horizontal scan resolution.

It is called Active Area Scanning.

Thank you Nashou66

So, follow up-question, the Barco V Size setting (that i have set to 0% to get 16:9) - Does it compress the whole raster area on the tube, or does it only compress the video image inside the raster area? Do you see what I mean? I hope it compresses the whole raster, I want all lines I can get

If I have the input set to 720p, does that mean that the raster is 720lines too, plus front and back porch or whatever it is called?

Again, sorry if this is a duh-question. It's been too long since I was playing with VGA and CRT timings

Compresses whole raster.

The image within the raster will be 720 lines, the rest you dont see.

Excellent, tnak you for clarifying for me.

Now, time to start thinking about Ile's ABL-mod for the 801s AMPS!
