BenQ HT4050 Home Theater Projector
Precalibration to HD Rec 709. The calibration on our test sample is exceptionally good, and would help most users decide to forego the expense of a custom calibration.
All glass zoom lens. Eliminates chromatic aberration that is present on the HT3050 and HT2050, contributes to a more seamless, elegant picture.
Frame interpolation system. Called "Motion Enhancer," the system inserts created interstitial frames to smooth the judder that happens in camera panning. The implementation is excellent, showing very little if any digital video effect
Ideal brightness for home theater. Rated at 2000 lumens, our test sample comes in at 1011 lumens in Cinema (Rec 709) mode with the lens at wide angle and the lamp on full. This is good for rooms that are not entirely blacked out, or for a very large screen installation. If you want to cut lumens, you can do that either by using the zoom lens or putting it into Eco mode. This flexibility lets you hit the sweetspot of brightness for most dark room home theater needs.
6x, RGBRGB color wheel. This color wheel configuration maximizes DLP performance potential for video by optimizing color brightness and bringing rainbow artifacts to a very low and inconsequential level for most users.
Zoom lens and lens shift. Traditionally inexpensive DLP projectors have minimal zoom range and no lens shift. The HT4050 has a 1.6x manual zoom and some limited vertical and horizontal lens shift as opposed to none.
Full HD 3D. Both projectors are full HD 3D compatible, and automatically recognize a 3D source. The DLP-link glasses synch instantly.
2D to 3D Conversion. Opens up picture depth and imparts a quasi-3D effect to 2D source material. It is not as pronounced an effect as with genuine 3D source material, but it works quite well.
Good onboard sound. The HT4050 eliminates one of the two 10W speakers found on the HT3050, so it does not have nearly the audio performance of the HT3050. But it is very good audio for a portable projector. Most home theater projectors in this class have no audio at all, as the assumption is they will be used with a surround sound system.
Color Temp and Color Management. The HT4050 has controls to fine tune color temperature with Red, Green, and Blue gain and offset controls, and the ability to adjust Hue, Saturation and Gain on RGBCMY.
Connections. You get two standard HDMI ports, (one of which is MHL enabled. You also get one VGA port, one 3-RCA component, one composite, one USB, one mini-USB, one RS-232, one 3D synch port, two audio inputs, and one audio out. The connection panel is on the rear of the unit.
Projection options. For those new to projectors, virtually all projectors are made with the ability to project upright from a coffee table, inverted in a ceiling mount, or placed behind a screen for either table/shelf mounted or ceiling mounted rear projection. All BenQ projectors have these options as standard features.
H+V keystone. If you need to use keystone adjustments, you've got both horizontal and vertical. This function is accessible only via a function button on the remote; it is not available in the on-screen menu. As always, on all native 1080p projectors we recommend avoiding the use of this feature if you can, simply because it adds scaling to the 1080p image, and it will reduce image brightness by turning off a portion of the chip.
Anamorphic lens compatibility. If you have an A-lens and want to use it with this projector, the vertical stretch required to accommodate it is an option in the aspect ratio selections.
Security. Password protection is an option if you want to use it, and the projector comes with a Kensington lock.
