Digistar 4K High Contrast
 |
 Up to 20 meters |
A JVC projection system uses two JVC 4K D-ILA projectors. These projectors provide good brightness but very high resolution with approximately 14 million pixels on the dome and excellent 10,000:1 contrast. The projectors are mounted either in the center of the theater or in the front and back of the theater cove and are blended together in a single blend region across the dome.

Multiple Projectors
Most video projectors have lower resolution than a dome requires, so to increase the number of Pixels on the Dome, multiple projectors combine together to create higher resolution. There are both advantages and disadvantages to this technique.
The greatest advantages include increased total brightness on the dome and increased total pixels. The greatest disadvantages include the need to achieve and maintain precise alignment between projectors and the need to have video from multiple projectors overlapping in "blend" regions that join the entire image together. The more projectors in the system the more challenging it is to maintain a unified image, and the more the blend regions around the dome become apparent. E&S has developed tools and procedures to make this alignment as easy as possible, and maintaining this alignment takes only about one hour per week.
