The Optoma H77 is this company's new top-of-the-line home theater projector. Incorporating the latest HD2+, 1280x720 resolution DLP chip and a 5x speed, 8 segment color wheel, it also offers a variety of user friendly features like a long zoom range, power zoom/focus, vertical lens shift, and a quiet fan to make it easy and comfortable to install in viewing rooms from small to spacious. And it's 3000-hour lamp life (in eco-mode) is a bonus for those looking for lower operating costs over the life of the product.
The H77 is rated at 900 ANSI lumens and 3500:1 contrast. It weighs 16.5 lbs, and is designed exclusively for home theater.
Connectivity. The video inputs on the rear of the unit include one DVI-I port, one set of 5-BNCs, one set of 3-RCAs, one S-video and one composite video. There are also two 12-volt triggers and an RS-232 port. Compatibility: Signal compatibility includes DVI-HDCP, component and RGB HDTV 1080i, 720p, EDTV component 576p, 480p, standard component video 480i, 576i, S-video and composite. Color systems include NTSC, PAL, and SECAM. Computer compatibility includes digital and analog up to SXGA 1280x1024.
Lens. The H77 has a power zoom and focus lens with a zoom range of 1.38x, which is a longer zoom range than we find on most digital projectors. It throws a 100" diagonal 16:9 format image from a distance range of about 11.25 to 15.5 feet. The unit also features manual vertical lens shift, which lets you position the image easily relative to the screen without tilting the projector and using keystone adjustments to compensate for the trapezoid. In its neutral position the centerline of the lens intersects the center of the projected image. Using the lens shift adjustment dial on the top of the unit, the image can be raised to the point where the centerline intersects the bottom edge of the image, or lowered to the point that it intersects the top edge of the image.
Picture control. The H77 offers three picture modes which Optoma calls Cinema, Normal, and Vivid. Each of these can be adjusted with controls on brightness, contrast, sharpness, and gamma. Video signals can also be adjusted on color saturation and hue. In the advanced menu there are independent controls on red, green, and blue contrast and brightness.
