This is the place to discuss the new Optoma HD81-LV
DLP projector. The HD81-LV is
the "Large Venue"
version of the two-piece HD81 1080p DLP projector.
First internet reviews:http://www.projectorreviews.com/opto...1-lv/index.phphttp://reviews.cnet.com/4505-7858_7-32469806.htmlMy observations
I upgraded to this projector after having 3 HD81's since October of 2006. The HD81-LV has the same outboard Gennum processor and projector chassis, same 300W bulb, same lens and 1.2X zoom ratio.
It features a RGBCYM 6 segment color wheel. The HD81 is capable of very good images, but suffers from inflexible installation, auto iris that is useless, on/off CR of no more than 2000:1 and poor full field blacks. Lumens on the HD81 after setting for D65 are in the 600 range in brightest modes. Very good resolution, connectivity, and colorimetry sum up the HD81, as well as being a good choice for anamorphic setups with features such as Auto235. The biggest concern is the amount of owners who have had reliability issues, needing to replace their projectors sometimes multiple times in less than a
year of use.
The HD81-LV appears to have several enhancements over the HD81:
Rated at 2500 lumens, great projector for large screen setups, especially at the price.(Real lumens in brightest mode likely to be around 1000 after D65 calibration.)UPDATE: My ISF tech measured a D65 calibrated 28 footlamberts on my Stewart 130 1.3 gain 100" wide screen with the projector at low lamp and iris closed down to 14--this is very different than the 9 footlamberts that CNET measured in their review.
Improved contrast and full field blacks--still not at the JVC RS-1 or Sharp 20K level.
Brilliant Color by TI which adds brightness to chroma and luminance, but also skews colorimetry. Big impact on brightness and CR.
A little quieter in low lamp mode.
Warranty improved to 3 year hot swap on projector, 1 year on bulb.
Continued Flaws from HD81:
Auto Iris still unuseable due to being slow and obvious mid-scene iris changes.
Film Mode 48Hz still not enabled when in LBX or Auto235 modes(anamorphic).
Most HDMI Video sources have to be set at DVI-PC vs. DVI-Video.
Source changing is slow.
Circular light halo around the outside of the image.
Out of box set up not as accurate as HD81's, image is plus green uncalibrated.
After D65 calibration, lumens are lower, more like an uncalibrated HD81 and brighter
than a JVC RS-1 or Sharp 20K.
New Issue--Colorimetry is skewed to the plus red/magenta side in Brilliant Color mode.
Reds look maroon and crushed. With Hue set properly for color bars, flesh looks too
red, I need to change Hue to +7.(Brilliant Color mode, non-calibrated projector)
After D65 calibration of projector with Brilliant Color off, turning it on makes it plus green.
Still no sign of downloadable firmware, promised a year ago on HD81, which
went through at least 4 firmware versions in as many months after release.
The lower cost HD80 is supported by net downloads of firmware from Optoma.
Reliability still suspect, another HD81-LV owner already had a failure at 30 hours.
Reports of heat related shutdowns in low lamp mode, same as HD81.
Update-New Issues: Momentary black screens when using component sources
at 1080i. This happens to my LV when using PS2 at 1080i.
Vertical lines reported by a few owners out of the box, sometimes
at left, sometimes at right, sometimes center. Gets progressively
Projector shutdown on me when pausing PS3 Gran Turismo 4 game.
