Optoma HD81-LV home theater projector: Sharpness
Like the HD81, the Optoma HD81-LV offers one of the sharper images available of the 1080p projectors.
Click on the left thumbnail for a closeup of the DTS logo (the thumbnail image gives you a good idea of how small a portion of the whole image, the logo takes up). For comparison, the middle thumbnail is from the JVC RS1, and the right most one, links to the same logo from the Sharp XV-Z20000. Pricewise, the JVC is the least expensive of the three, but not by that much.
Bottom line: A very sharp image. Watching the Optoma HD81-LV home theater projector filling my 128" diagonal screen from just over 11 feet (very close compared to where most people would sit), the Optoma, like the Sharp, and Mitsubishi, produce that "razor sharp" type image, that we are all looking for. Step back a few more feet, and it looks so sharp, that it's like looking out a window.
