Apparently the image quality is good, but overall they are a PITA to install, configure and use.
Advantages[edit]
- Long service life; CRT’s maintain good brightness to 10,000 hours.[2]
- High-end CRT projectors can precisely display images up to 1920 x 1200 [3][4] with accurate color reproduction. A few projectors can scan at even higher resolutions up to 3200 x 2560, although their ability to resolve fine detail at this resolution is greatly reduced.
- Superior black level compared to LCD and DLP based projectors.
- As with CRT monitors, the image resolution and the refresh rate are not fixed but variable within some limits. Interlaced material can be played directly, without need for imperfect deinterlacing mechanisms.
- Very fast response time (especially when compared to LCD-based projectors), resulting in minimal (if any) motion blur when showing video with fast motion.
- CRT projectors do not show a rainbow effect seen with single chip DLP projectors.
