When I had my 8500 I liked 1280/960 @ 72 for 4/3 material and either 1440/960 or 1280/720 @72 for 16/9.
I have seen three 8500s and the condition of the tubes as well as your mech and opt/elec setup will determine if it likes 1440/960. If anything is not perfect you may have some softetning at that res on a compressed raster.
Steve's hit the nail on the head.... start at 1280x720 if you're doing 16x9 or 1280x960 if you're doing 4x3. If you dial it in 100% and can still see scan lines, go up to the next level. If the tubes are old & tired, try going down instead. These are good starting points however.
It depends on the condition of the projector, the level of setup and also the input source.
1440 X 960 @ 72 is somewhere around 73Khz. That puts the projector well into the high band. And that's also 960 lines of resolution on a 16X9 section of the CRT. The maximum vertical resolution of the 8500 is 1100 lines, but that's using a 4X3 aspect ratio (the intire area of the tube).
At 960P you're pushing it. And it would take a masterful work of using as much area of the CRT's surface, to include being able to work some magic with the coils, rings, etc. Actually you should be able to see scan lines, or see them barely touch each other, otherwise you'll be running at a resolution that would give you the benefits of having a film like image (softer) because the lines are running together, or you'll get the benefit of cleaning up noise from the processor or cables with this softening effect. But during proper tweaking you should always look for lines. And that is THE reference for proper setup.
A good quality (low noise) input source makes things much better. And a good quality HTPC has been the best source I've seen so far.
The 8500 is rather easy to setup. as said, start with 720P first.
Good info guys. I have been trying different resolutions on my 8000 with tired and worn tubes. It looks best at 960X540 for 4X3 and 1280X720 for 16X9. It's still not good enough though. I can't get good focus on the edges and you can see visible wear on the screen.
I have an 8500LC coming and I'm sending Mike P. a brand new Radeon 9700 Pro to mod for me.
