Another option is replacing the screen. You can eliminate those small dots that you see by installing a better screen. The draw back is you need more control over your lighting as if you had a front projection tv.
Does DigiVision Pic Enhancment work ?
My DVD video signal is projected with a Mitsubishi 55inch projection TV. Since many of us including me are never really happy with the picture quality, I would like to know whether you guys have any experience/opinion of the new 'lifesafer for large-screen TVs' DigiVision HT-70e which AA offeres recently. I am sceptical whether one can inprove the picture without increasing the resolution of the TV. The new system increases basically the contrast (edge) of pixels for 2 grand. Is it worth trying?
