I have a serious question about FD Trinitron monitor tubes, I recently ordered a CTX PR500F monitor that has Sony's FD Trinitron picture tube in it. Anyway, what I would like to know is, why is there a slight space between each horizontal line on the monitor? You can really see what I mean when you go lower in resolution. For example, like when your in dos prompt and when you look at the letters, it appears that every other horizontal line is missing making the picture not as solid and bright as it should. Most of the applications I use are about 320*200 to 640*480, this problem strains my eyes and dims the picture, so this is very important to me. I understand that the higher the resolution you go with this monitor the horizontal lines connect together solidly, they also connect together solidly when you shrink the vertical size of the monitor screen even when your at a real low resolution.

So what I am trying to get at here is, is there any possible way that FD Trinitron tubes can correct the problem I'm having with this monitor (or any other FD Trinitron monitors)? If so, how? And if not, why not? And if not, I suspect that there has to be a way to fix this, maybe tricking the monitor that it should display the resolution 2 times the current one, that will help a little. So is there any way?

i have a trinitron ,but dont know how to help you.
maybe this can help though http://www.ita.sel.sony.com/products/displays/

I have a Trinitron in my office (NEC monitor). I set it to 640x480 and I think I can see what you are saying. The bright lines of the raster scan don't touch each other. But on my monitor, they aren't all that far away from each other either.
Got a CompUSA near you? Go into the store and find the monitors they have on display. Locate a Trinitron similar to yours and ask an employee if he or she would set it to 640x480. Compare it to yours and you'll know if your monitor is shot or if it's just the nature of the beast.

Could this be related to the refresh rate? Just guessing...

The way many monitors work, the CRT shoots the picture onto the screen one line at a time, refreshing it 60-72 times per second. Some monitors (interlaced) will shoot every other line, while some do each individual line. The image, theoretically, is supposed to "glow", for lack of a better word, until the next time the pixel is lighted. So I'm thinking maybe the refresh rate is a bit slow, and the individual dots are not staying lighted until the next time the CRT shoots an image to them.

Then again maybe someone put orange juice in my orange juice...
