Hitachi UltraVision Projection TV Information
For those in the market for a big screen HDTV plasma is certainly an attractive option, but be prepared to spend at least twice as much as the CRT alternative for a smaller screen. That's what makes the CRT based Hitachi UltraVision Projection TV such an attractive option for the average consumer.
Hitachi is the only maker of rear projection TVs that designs and manufacturers its own CRTs, lenses, and video processing circuitry. The new wide neck CRT used in the XWX/SWX line is claimed to offer more brightness and sharper detail while reducing beam-spot size by an average of 10% across the usable range of cathode current. The tube's wider neck accommodates a larger electron gun that's said to improve focus and detail by 20% compared to older Hitachi UltraVision Projection TV sets.
In addition, the new Hitachi UltraVision Projection TV models have a 17% larger picture area compared to previous designs. This is accomplished by putting the power lens closer to the CRT than in any other system currently on the market. Other lens systems, the vast majority of which are now made by a division of 3M, place the power lens after a pair of corrective lenses. Hitachi's new Super Contrast lens is claimed to be 43% brighter and 30% sharper than the industry standard, while being compact enough to let Hitachi make a 65" diagonal set that is only 28" deep.
Some Hitachi UltraVision Projection TV models include a special Deep Black Anti-Reflective Shield. In a nutshell this is a special screen coating that is said to reduce reflectivity to about 0.5%. Other key performance features which are offered in Hitachi models include their Magic Focus auto-convergence system, which has a manual 117-point override that can be used to touch up the automatic system; Virtual HD, Hitachi's horizontal and vertical upconversion system, which can upgrade standard NTSC to 540p or 1080i; and 3:2 pull down correction with 26-point Motion Adaptive Interpolation for video sources. The Hitachi UltraVision Projection TV is mover friendly as well. This can be very important when shopping for televisions of this size. The screen of a Hitachi UltraVision Projection TV can be unbolted from the main chassis so the set can be moved in two pieces. This, combined with Hitachi's product design can give you the perception that your Hitachi UltraVision Projection TV is smaller than the competition. Do not let yourself be fooled. You will see its massive screen size the minute you switch it on at home!
