A feature called Local Contrast Enhancement utilizes the LED light source to enable 1000+ local-dimming zones to adjust bright and dark detail. The HT4550i also features BenQ's HDR-PRO technology to facilitate HDR tone-mapping and contrast.
However, the report does provide the coverage of the color gamut, the Picture Modes that cover them, the test conditions, and the gamma tracking.įortunately, when measured, the HT4550i does prove to be very accurate and achieves the promised 100% coverage of both the DCI-P3 and Rec.709 color space, which will be covered in more detail in the Performance section. BenQ says the tolerance of their automated calibration insures a Rec.709 DeltaE of less than 3, which is acceptably low, and that measuring and printing the precise dE for each measurement point would impact production speed. The report does not display the DeltaE-the error-of the points used to measure this coverage. BenQ provides a factory calibration report showing the unit's coverage to these specifications within the color gamut.

The HT4550i utilizes BenQ's Cinematic Color DCI-P3 technology, enabling full 100% coverage of the DCI-P3 and Rec.709 color space through the use of a Wide Color Gamut (WCG) Filter. To determine the installation location and throw distance for your preferred screen size, please reference the ProjectorCentral BenQ HT4550i Projection calculator. However, in temporary installations, it can be a viable solution.

It is important to note that utilizing any form of digital keystone or warping can impact image integrity, so it is advised to take the extra time needed to install the projector in a way that avoids the use of keystone. Additionally, a 2D keystone adjustment is provided, allowing for a ☓0-degree adjustment in both vertical and horizontal keystone. This could be somewhat corrected using the horizontal shift however, vertical lens shift should ideally only influence the vertical axis. I did notice that at the upper end of the vertical lens shift range, the image would actually move up and to the right slightly. It provides a 0% to -60% vertical adjustment range and a ☑5% horizontal shift. The HT4550i offers both vertical and horizontal lens shift capabilities. For my 100-inch diagonal image, the HT4550i was placed approximately 9.7 feet away, which aligns with BenQ's distance-to-screen chart.
I found the provided distance chart to be accurate. The throw ratio corresponds to approximately 2.4 feet to 32.6 feet, allowing projection of an image as small as 30 inches diagonal up to a massive 300 inches diagonal.

Its lens has a 1.15-1.50:1 throw ratio for a 1.3x manual zoom and focus, which, thanks to smooth mechanical operation, made it easy to dial in the image. The HT4550i features optics with a 0% offset to the screen, so the centerline of the lens from a ceiling-mounted projector would be at the center of the projected image prior to being moved down by the available -60%vertical lens shift. BenQ offers its CM00G3 Universal Ceiling Mount as an option, with a $59 MSRP at the time of writing. It supports various mounting options, including standard tabletop or ceiling for front- and rear-projection.

Weighing 14.55 pounds and measuring 16.54 x 5.31 x 12.28 inches (WHD), the HT4550i is not a lifestyle or portable projector but is still compact and lightweight enough to be moved around with ease. However, the dynamic contrast does improve when SmartECO is used. The HT4550i has a published contrast specification of 2,000,000:1 with dynamic light source dimming, but its native contrast ratio without light source dimming measured at 900:1, which is relatively low and noticeable in content. The light source has a long life of 20,000 hours in the Normal and SmartECO Light Source Modes, and 30,000 hours in ECO, ensuring years of use without the need for bulb replacements. Nevertheless, the best picture modes do measure well for accuracy and provided a fair amount of measured brightness and vibrant images. It's good to see an LED projector hit this kind of brightness, however, this mode is noticeably green-biased and its default color temp cannot be adjusted from the projector's Native setting to the more accurate Normal color temperature. Our sample's 4LED light source (RGGB, with an extra green LED for brightness) also exceeded the specified 3,200 ANSI lumens, measuring 3,413 ANSI lumens in its brightest picture mode.
During testing, the HT4550i thankfully provided a crisp and detailed 4K UHD image without demonstrating any rainbows, which can sometimes occur with single-chip DLP projectors. This resolves the 8.3 million pixels on the screen to display 4K resolution.

The new BenQ HT4550i utilizes a relatively new Texas Instruments 0.65-inch DMD DLP chipset to achieve its 4K UHD resolution of 3840x2160 from a 1080p native array with four-phase pixel shifting.
