For those who are new to this, "gain" is the adjustment for the bright end of the grayscale, while "bias" is the control for the low end. Just remember that Bias and Black both start with B, and you'll be fine.
By the time we were done, color temperature was within 100 degrees of 6500K across the board. This is outstanding performance for such an inexpensive projector.
Connectivity. The HD33 features a pair of HDMI 1.4 inputs, a set of YPbPr component inputs, a VGA port, composite video, USB, RS232C, a VESA sync port for the RF emitter, and a 12V trigger. S-Video is missing, though I doubt it will be missed. The other thing that is missing is a hardwired control panel; the HD33 relies entirely on its remote control. The only button on the case is to turn the power on and off.
Color wheel. With a 3x-speed, 6-segment RGBRGB color wheel, the HD33 waves a fond farewell to the rainbow effect. Here's where it gets tricky: the HD33 has a refresh rate of 120Hz and the color wheel goes through three full cycles per frame, for a 3x refresh rate. If this projector were running at 60Hz, the same wheel speed would be referred to as 6x. If you see both numbers around the Internet, this is why. This wheel configuration should eliminate color separation artifacts for all but the most hypersensitive viewers. In fact, this paragraph was almost omitted from the review because, after not seeing any rainbows over several days of testing, I forgot that they were even a concern.
Lamp life. The HD33's lamp is rated to last up to 3,000 hours in Bright mode and 4,000 hours in Standard. This is fairly typical of home theater projectors. However, replacements cost only $249, making it less painful when the lamp does finally burn out.
