They're also very large, about 150 - 200lbs, so you need the correct framework to guide them. CRT projectors also need accurate placement. They should be perfectly square with the monitor, at the right elevation for good image quality.
Furthermore, while many digital projectors have move lenses, allowing the projector to be placed at a selection of range from the monitor, CRT projectors should be at a really accurate distance for a specific monitor size. These factors seriously limit place options. While the bigger CRT projectors put out more gentle than their smaller alternatives, they've pretty poor pictures in comparison to even the most affordable Home Projector
projectors. Ultimately, CRT projectors require particular setup in order to get a watchable, much less an ideal image.

The bigger the projector lumens rating, the brighter the light wave depth will soon be and the better the projection screen. Even though lumens isn't immediately related to how big is the projected picture, a more substantial picture will need to be lighter as the projector must be more far from the monitor and will need more lumens.
The projectors available today generally selection between 500 and 10,000 lumens. If there is normal gentle in a room, running a projector with increased lumens is likely to make the picture more defined. Gentle in a movie space could make a graphic with 1000 ANSI lumens look washed out and tougher to see. In the exact same space with exactly the same quantity of light, a projector with 1800 ANSI lumens will undoubtedly be much easier to see. It is essential to be sure that the projector lumens rating is measured in ANSI.
