If you wish to turn the projector back on, you must wait until the projector has completed the cooling cycle and has entered standby mode. To raise the image: 1. Press the elevator button 2. Raise the image to the desired height angle the button to lock the elevator feet into position.

Since big-screen TVs are now rumored to be a leading cause of divorce in America, the front projection alternative is the happy solution to marital harmony. While on the subject of installation, we may as well point out some limitations posed by the HD It has relatively limited throw distance flexibility and no physical lens shift.
For whatever reasons, DLP projectors in general lag behind LCD projectors in delivering extended zoom range and lens shift capability, making them less user-friendly when it comes to installation. LCD projectors have made great headway in home theater market share in no small part because they simply fit into a wider array of room configurations than do most DLP projectors.
The HD72 is no different in this regard. The 1. Since a " diagonal image is 87" wide, this means that the projector will be at a distance of 1. That is a viewing distance many people find comfortable for watching large screen movies. If you are among them, you will find that the projector is situated very close to you. You might place it on a low table between two seats, or you might ceiling mount it directly above the seating area.
A less practical solution would be to place the projector on a shelf or stand behind the seating area. That is because the HD72 has a built in throw angle offset that equals about 1. So if you set up the projector at a distance of 12 feet from the screen for a " diagonal image, the bottom edge of the projected image will be about 18" above the centerline of the lens.
In other words, if you set the projector on a rear shelf behind the seats that is, say, four feet off the floor in order to clear the heads of viewers, the bottom edge of the image will be 5. That is too high for most typical home theater situations. You could correct the problem by tilting the projector downward and correcting the resulting trapezoidal image with keystone correction, but that is a solution you should try to avoid if you can.
You might also think about putting it on a very high shelf and inverting it. That may solve your particular problem geometrically, but you must not place a projector upside down with the top casework in direct contact with a shelf. Projectors are built to dissipate heat in part through the casework, and if heat dissipation is inhibited, overheating will result. So the simple fact is that many users of the HD72 will find that ceiling mounting provides the happiest solution-it gets the projector away from the viewers, and you can put it virtually anywhere on the ceiling to achieve precisely the right image size you desire.
And as noted above, because it is small and white, it will virtually disappear against a white ceiling when not in use. If you use the projector with an electric or manually retractable screen, or a fixed, wall-mounted screen with curtains, the system can be made to disappear when not in use. That gives you the option to define the space as something completely different than a dedicated video room.
Several of the latest widescreen projectors to come to market feature the classic WXGA computer resolution format, x The HD72 is one of them. The aspect ratio of this format is The advantage to this format is that it will display both x and standard XGA x computer outputs in full frame native resolution without cropping or compression.
For those using these signals this is a significant advantage. If you view a lot of line material you may want to have your screen cut to a aspect ratio so you can view it full frame. With that set up, your HDTV material will be displayed in x, and there will be small black bars at the top and bottom of the image. On the other hand, if your viewing material is HDTV, DVD, and television, you will want to use the operating mode, which is x
