Optoma HD81 DLP Projector Review
If you are looking for a projector to simply get an image up on a screen, the HD81 from Optoma is likely one you are going to pass over. It's hefty array of features make it ideal for the serious HT enthusiast looking for a native 1080p projector that full fills a few other purposes. It has an exceptional range of input options and a reported 10,000:1 contrast ratio.
The feature that caught my eye was the Gennum VXP video processor. You essentially get a $3000 video processor included with the price of your projector. However, there are a couple of things that could be improved to make this a perfect projector.
From the article:
You can perhaps see that to hit your target screen size (and this
projector is certainly bright enough to go to a larger sized screen)
you’re going to have to have a fairly long room. I would have liked to
have seen a bit more zoom on this lens, or at least the option to order
a shorter throw lens for rooms that capitalizes on width and not depth.
With the $9,999 retail price tag of this projector, Optoma is betting
that this device will make its way primarily into dedicated theater
rooms with a long throw or double row of seats. In my reference room I
wasn’t able to hit my 100-inch Stewart StudioTek 130 at full size from
the fixed mounting position and had to back the unit up against the
back wall on my portable projector stand.
Here is a bit about the video processor.
Gennum VXP-based Video Processing (FineEdge, Fidelity Engine and TruMotionHD)
is Gennum’s acronym for “Video eXcellence Processing” This system
utilizes the GF9351 chipset and provides an incredible amount of
features that includes: full 10-bit video processing, directional
interpolation algorithms (jaggie reduction), pixel-based motion
adaptive deinterlacing (2:2 and 2:3 pull-down) with bad edit detection,
and noise reduction on both SD and HD content.
