Overview of the DLP Technology used in the Optoma HD806
DLP is a video projection technology, developed by Texas Instruments, that utilizes a chip, referred to as a DMD (Digital Micromirror Device). Every pixel on a DMD chip is a reflective mirror.
The video image is displayed on the DMD chip. The micromirrors on the chip (remember: each micromirror represents one pixel) then tilt very rapidly as the image changes.
This process produces the grayscale foundation for the image. Then, in a single chip DLP projector, such as Optoma HD806, color is added as light passes through a high-speed color wheel and is reflected off of the micromirrors on the DLP chip as they rapidly tilt towards or away from the light source. The degree of tilt of each micromirror coupled with the rapidly spinning color wheel determines the color structure of the projected image. As the amplified light bounces off the micromirrors, it is sent through the lens and can be projected on a large screen.
In more advanced, and much more expensive, DLP projection systems, such as digital projection systems that may be used in your local movie theater, use a 3-Chip design (one chip for Red, one chip for Green, and one Chip for Blue). In these systems, the spinning color wheel is not required.
The Optoma HD806 employs the single chip/color wheel system.
Product Overview
1. DLP Video Projector with 2,000 Lumens of light output and 1920x1080 (1080p) Native Pixel Resolution.
2. Image size range: 30 to 300 inches - adds flexibility for both small and large screen sizes and room environments.
3. Native 16x9 Screen Aspect Ratio. The HD806 can also accommodate standard 4x3 aspect ratio sources. The 16x9 aspect ratio is desirable for widescreen films and HD sources. The aspect ratio can be adjusted to 4x3 for projection of material shot in the 4x3 format.
4. 8000:1 Contrast Ratio. 300 Watt Lamp.
5. Six-segment 2X speed color wheel.
6. Two HDMI, and one each of the following: VGA (via adapter to DVI), Component (Red, Green, Blue), S-Video, and Composite Video (Yellow) inputs. Any standard video source, except RF sources, can be connected to this projector.
7. Compatible with input resolutions up to 1080p. NTSC/PAL Compatible.
8. Video Deinterlacing and upscaling to 1080p via Pixel Works DNX video processing.
9. Manual Zoom and Focus controls. On-screen menu system for other functions. Wireless remote control provided.
10. Automatic video input Detection - Manual video input selection also available via remote control or buttons on projector.
11. Dimensions: 16” x 4.6” x 12.2” (406 x 117 x 310 mm)
12. Weight: 10 pounds.
13. Power Consumption: 435 watts (full power), 375 watts (ecomode), 14 watts (standby power).
15. Optional Accessories: Anamorphic Lens/Sled Kit, Ceiling Mount, External IR Module.
Setup and Installation
First setup a screen (size of your choosing). Then, position the unit at the optimal distance from the screen (your choosing). I chose to place the unit on a mobile table to make this easier, but the HD806 can be ceiling mounted with an accessory mount.
Starting up the projector is fairly easy. First, plug in your source (such as a DVD, Blu-ray, or HD-DVD player) to the proper video input. Then, plug in the power and turn on the power using the button on the side of the projector or the remote. It takes about 30 seconds or so until you see the Optoma projected on your screen, at which time you are set to go.
At this point, you can raise or lower both the the front and rear of the projector using the adjustable feet, and you can also adjust the actual lens angle using the Image Shift function on the remote control. You can also use the Zoom control on the lens to get the image to fill the screen properly. After this, you can use the mnaual focus control to sharpen your image.
I found that the HD806 automatically searches for the input of the source that was active.You can also access the source manually either via the projector's onboard controls or via the remote control.
