Ok....I am working on a Runco-933 setup for my old man. How should I set it up to where the picture on the screen would fit correctly? If I try 1280x768, I could get the correct width but the vertical is then too big for the screen on some movies. Am I using the wrong resolution. Should it be 1366x768 or 1280x720, or 1366x720?
Can I do what I need to with the current equipment? Or do I need something else? Any software out there I can try?

This is what I have to work with.

-Runco DTV-933(NEC 6PG XTRA)
-PC with a Nvidia 8600GT video card
-100 inch 16:9 screen

1280x768 and 1366x768 are goofy "PC" resolutions. Without getting into an esoteric discussion on non-square pixels, if you have a 16:9 screen, then you should use a 16:9 resolution. 1280x720p should be a good match for the 933.

...... very closely Wink

I'm dealing with same projector myself, debating wether to use my 96" wide screen (10' diagonal) or a 67.5" wide screen. Been watching my ECP 3100 on the 67.5" wide screen throw distance of 103" floor mounted 28" above floor. My viewing distance is roughly 14.5' from screen location to seating behind projector. Ready to ceiling mount either the ECP or DTV 933 or 900A.

What I wanna know is, if the very first thing i do with a pj is set the tube raster and image size on the tubes (as equally as possible on each color without overshooting phosphor area) should i pretty much use the recommended throw distance as a start point but not gospel? Seems to me this very first step would determine all settings to follow including mounting distance to screen with locked-in lateral settings for various screen sizes. ?????

anywho, i will continue in my efforts to see the CRT light at the end of the tunnel........

Yes 1280x768 is a 16:10 resolution as far as i recall, and 1366x768 is usually the native res of some older standard definition plasma and LCD displays.

You should be able to get it to easily do 1920x1080i or as Ecrabb said 1280x720p, you might need to use Power strip or make a custom resolution in the nVidia control panel.

I've had the best results with 1920x1080i@96hz. That's on a BG808s though.

1080i would probably work nicely for a 6PG, too... The only problem is how small it makes icons and other desktop graphics. That's why 720p is nice. So, you can either switch back and forth, or deal with the disadvantages of going either way.

I was also trying to keep it simple for him for now. You don't usually need PowerStrip to get 720p/60. 1080i/96 would definitely require PowerStrip, and it could be tricky for some people to even figure out if it's working.

The OP should just try a few different 16:9 resolutions and see what he likes.

I've been playing with 1080i/48 this week. Long slow pans or aerial shots have this smooth look to them. I watched the opening of "The Shining" a few times where they have the helicopter flying over the river and the road in the mountains

Again though, that's power striped.

You need to start with making the center lines of the cross match up, do that by angling the tubes to match the green, use the deflector yokes to match them all level, then use the centering rings to match the height of the horizontal line.

Once youve done that, flick the blue and red off, and make the green image a nice shape so its not bowed, skewed, keystoned, or anything else like that by using one of the crosshatch paterns.

Then turn off the green, and make the red look like you just made the green, and once you think youre close, turn the green back on and make the red match the green by adjusting the bow, skew, tilt, etc so that they match up.

Then turn off both red and green, and do the blue, then turn on the green, match the blue to the green same as you did with the red.

If all goes very well, by this point, you should have all 3 colours pretty much aligned across the whole screen, and should not have even had to touch the static convergence yet.
