For starters, with your 800x600 PJ you are only using 800x450 of your panels in a 16x9 setup. 800x450=360,000 total pixels.
For comparision, take a 16:9 Panny L300U with 960 x 540 panels. Here you can use the full panel for your 16:9 screen and get 518,400 pixels, a 44% increase. More pixels on the screen means less screen door for the same size screen. (the Panny may also have some LCD construction additional features that minimize screen door.)
You will also get a boost in the lum light output as well since you will be able to use all the pixels to lightup your screen instead of displaying black bars on the top and bottom.
Another itemis fill factor. This is the actual size if you will of the pixel within the displayed image. The better the fill factor the less screen door is an issue. LCD technology tends to have the lowest (worst) fill factor followed by LCD with MLA, followed by DLP.
