The Sony Bravia VPL-VW40 front projector, for example, costs $3,000 but displays images at a vertical resolution of 1,080 lines and 60 frames a second, the highest on the market.
The VPL-VW40, which will be available next month from sonystyle.com and other outlets, uses Sony’s 1,920-by-1,080-pixel image panels to project a sharp image measuring up to 25 feet diagonally. It includes two HDMI connections, a component input, a composite input and a PC video input. It can be mounted on a ceiling or placed on a floor stand.
Like most projectors, the VPL-VW40 includes keystone correction for fixing images when the projector is at an angle to the wall. You will need an external video source because the projector does not include a TV tuner.
Put the VPL-VW40’s giant images next to a puny 42-inch plasma, and maybe that $3,000 price tag won’t look so big after all.

Lamp Life
Lamp life for a projector will vary based on many factors including application, installation, intake of cool air and exhaust of hot air, usage, and proper maintenance. Heat buildup can reduce lamp life and even damage your projector. Here are some tips to help your projector lamps last longer.
1.
Once you turn on your projector, wait at least five minutes before turning it off to allow the fan to properly cool the unit. After the fan has cooled your projector, you may unplug it and store it as desired.
2.
Do not obstruct the air intake or exhaust vent. Paper should not be placed on top of a projector, or where vents are located.
3.
Keep the exhaust vent at least two feet from any object.
4.
If the projector is built into a compartment, wall, ceiling or shelf mount, the minimum distance requirement (usually at least two feet) stated in your owners manual must be maintained.
5.
Clean the projector's air intake filter every three to six months -- or more frequently -- based on your operating environment.
6.
Do not move your projector until the lamp has cooled (about five minutes).
7.
Run your projector for two weeks and/or 20 hours shortly after your purchase. If the lamp is going to fail, it will usually occur within the first ten hours of operation. Lamp warranties typically last just 90-180 days from the date of purchase, rather than the first installation.
8.
When you purchase a replacement lamp for your projector, remove the existing lamp and use the old lamp as your spare. If your projector is new, test the original lamp for the two weeks/20 hours before removing and storing as a spare.

Casio Xj-360 - the survey
Xj-360 - this is technology High-end, placed in the smallest possible space - mobile prezentatsionnoye device, which ideally is suitable for the contemporary man of business. For this Xj-360 is completed by output RGB for the image transmission to another (additional) monitor and easily it can be fixed on the ceiling.
- Brightness of 2200 lumens: Even the bright accomodation Xj-360 excellently reproduces image - "bright" impressions from your presentation are guaranteed! !!!! Automatic correction of the trapezoidal distortions: With the selection of place for Xj-360 the owner will not collide with the strict limitations: his function of the full-automatic correction of trapezoidal distortions rapidly corrects image to the correct form.
- Dimensions of size A5: For conducting the presentations you can take Xj-360 with yourselves where conveniently. Because of its compact sizes, it will engage a little place in your bag. By size not more than the size of paper A5, Xj-360 entirely shows, on that is capable the technology "high-end".
- RGB the output: Xj-360 is completed RGB by output for the image transmission to the additional monitor, which can be arranged in other, convenient for you place of
1,8 kg: With weight only in 1,8 kg, Xj-360 the present lightweight, which gives to its owner the outstanding freedom of the movement
Wide-angle zoom lens, the two-fold optical increase: The high coefficient of increase Xj-360 gives the enormous possibilities: When your desired distance projector- screen it is possible to double, in this case the dimensions of the projected image to leave constant. Distances of 1m '0sm is sufficient for the projection of image with size into 1m 20sm... - this freedom of choice will make your success obvious both in the small telephone-box and in the large conference hall Ceiling fastening: Xj-360 when desired or need easily is attached on the ceiling, making it possible to optimally use free space.
