“The BenQ HT4550i 4K projector is calibrated out of the box, but it gets even better with a few tweaks.”
  • Amazingly accurate color
  • Bright 3,200 ANSI lumens image
  • HDR modes for days
  • Comes with Android TV
  • Vertical/horizontal lens shift is excellent
  • The fan is quiet
  • Built-in sound isn’t great
  • Black levels suffer a bit in light rooms

BenQ’s premium-level home theater projector, the HT4550i 4K HDR LED, does not disappoint. Designed for “AV content fanatics and movie aficionados,” the HT4550i sits at the top of BenQ’s offerings for 2023 thanks to 4K UHD (3,840-by-2,160) resolution, impressively bright 3,200 ANSI lumens, and Android TV built-in (well, sort of).

The upgraded follow-up to BenQ’s popular HT3550, the HT4550i holds its own in moderately bright rooms — as it should at a cost of $2,999 — thanks to its solid-state LED light source. But it’s no surprise that it excels in the dark, where its exclusive HDR-Pro (with HDR10+ support) and CinematicColor tech that allows for 100% DCI-P3 color coverage pump out respectable black levels and beautifully accurate color that is factory-calibrated and out-of-the-box ready.

Beyond the box, though, the HT4550i has adjustable picture settings for days, allowing users to dial in their perfect image with ease. And it didn’t take long to turn my modest basement into a gobsmacking home theatre, either. The HT4550i is easy to move around during setup, thanks in part to its vertical/horizontal lens shifting and other image-fitting features.

But is it worth the three-grand price tag when you could get into an ultra short throw or laser projector in that same ballpark? Let’s find out.

Setting up a projector — especially one in this price range that’s meant for more dedicated home theater setups — can be intimidating. And while things like placement distance and height, as well as keystone and focus adjustments, need to be taken into consideration with any projector, going from unboxing to showtime with the HT4550i is pretty straightforward.

The included quick-start guide includes a helpful distance-to-screen chart for figuring out where it should be placed in a wide range of room sizes. For example, while the chart has measurements for an image size as small as 30 inches, BenQ recommends a minimum 60-inch image, with the projector at a minimum distance of around 5 feet. On the maximum end, it recommends a 200-inch image at a distance of around 16 feet. I projected a 100-inch image on a 16:9 screen and placed the HT45501 about 9.5 feet away.

The BenQ HT 4550i has a 0% to -60% vertical lens shift and a +/- 15% horizontal lens shift, which means that you have some leverage for moving your image left, right, and up and down to perfectly align it to the screen using the manual shift dials on top of the unit. I did notice that while shifting the image vertically to fit my screen, the image skews slightly up and to the right, requiring you to adjust the projector’s position to compensate. It’s not a big deal, but worth noting. The HT4550i’s manual 1.3x zoom and manual focus allow for easy size adjustment, fine-tuned fitting, and focusing, which I actually prefer over automatic focus.

The HT4550i also has auto 2D vertical keystone adjustment and manual horizontal keystone adjustment, but because I measured things out correctly and adjusted the shift myself, there was little or no keystone adjustment needed (if it did it automatically, I didn’t notice). This is actually the ideal situation you want, as too much keystone adjustment can potentially skew the image.

The HT4550i (the “i” signifies its focus on streaming content, BenQ says) has two HDMI 2.0 inputs (with eARC support) for connecting a range of sources, from Blu-ray players to streaming devices like Apple TV or Roku, but it does come with its own Android TV dongle that you install on the back of the unit. All you need is a screwdriver to remove a small cover and then the dongle just connects to an HDMI port and then to a mini-USB power cable. The cover goes back on neatly, concealing the dongle. Or, you don’t have to use it at all. Your call.

Setting up the Android TV interface is standard, and it comes with Netflix and several other streaming services preinstalled. Those that aren’t can just be downloaded from the Google Play Store. I opted to also connect my Apple TV 4K to the HT4550i, which was great because I could use its AirPlay connectivity to have sound come out of my existing Sonos surround system. Otherwise, I used the projector’s built-in 5-watt speaker, which is actually not bad in a pinch, but it’s not great as a permanent option. With SPDIF and a 3.5-mm audio-out port, connecting to other audio sources you have is also easy, but there is no Dolby Atmos support, just Dolby Digital Plus.

The unit itself is made of sturdy plastic with a sleek matte finish and measures 16.54 by 5.31 by 12.28 inches, and there’s a tethered, snap-in lens cover and a slide-over cover for the focus and zoom dials, all to help keep dust at bay. Lastly, the HT4550i comes with a remote that controls both the projector and the Android TV dongle.

Brightness, color, and HDR

The BenQ 4550i uses the company’s 4LED light source that boasts 3,200 ANSI lumens of brightness, which is impressively bright for an LED projector, especially one in this price range. BenQ says that the 4550i is “specially designed for moderately dark AV rooms,” and it’s right on the money.. The HT4550i’s image brightness blew me away when the lights went down, creating an excellent viewing experience that’s so clear that I had to compare it to my LG OLED for reference. Driving that clarity is a Texas Instruments 0.66-inch DLP 4K UHD chipset capable of delivering a native 4K image of 3,840 x 2,160 (8.3 million) pixels.

The HT4550i projector uses BenQ’s new CinematicColor DCI-P3 tech to deliver what BenQ says is accurate enhanced colors. When the projector is in HDR mode (it automatically detects an HDR signal and adjusts), BenQ’s new Wide Color Gamut (WCG) feature is activated (it can also be turned on manually), which widens the color gamut from 100% Rec.709 color space to full 100% DCI-P3. Developed by the Digital Cinema Initiatives (DCI) and the Society of Motion Picture and Television Engineers (SMPTE), Protocol 3 is the RGB color space that is the standard used in the digital cinema and film industry, meaning that with this active, you should be seeing the movie’s colors the way that the filmmakers intended. On top of that, the HT4550i’s HDR-Pro and Local Contrast Enhancer features enable more than 1,000 local dimming zones that further help with color accuracy, as well as better preserve darks and lights when watching in HDR10, HDR10+, and HLG viewing modes.

Performance and picture modes

All the specs and big numbers aside, the picture on the HT4550i is absolutely gorgeous. In my experience, a 100-inch image in my small-to-medium-sized basement TV room was perhaps a bit big for the space, but its clarity, color, and dynamic contrast made for an excellent viewing experience with movie-theater impact, whether watching SDR or HDR titles. Sure, when I opened the blinds in by basement and let some daylight into the room, some of the blacks and shadows suffered (this happened sometimes when bumping up brightness levels, too), and I probably wouldn’t make a habit of doing this. But overall, contrast (especially in HDR modes) was better than expected.

The HT4550i offers a wide range of picture modes that are well-calibrated and look great out of the box without any adjustments at all, which is great if you’re new to the projector world. But should you want to tweak things, the level of available fine-tuning you can do with this projector is off the charts.

For testing out SDR movies, I used my Apple TV 4KK, dropping the resolution down to SDR 1080p in the device’s settings. I then threw on some scenes from Pulp Fiction and The Hangover on Netflix. Picture modes for SDR include Bright, Bright Cinema, Cinema, Filmmaker Mode, and User. For the screen, I used a mid-priced, 100-inch matte white screen with a 1.1 gain reflection, but if you were going to get a bit more serious, you could go for a premium screen like Elite Screens’ Aeon Series CineWhite fixed frame screen with a 1.3 gain, which would add even more brightness.

Although BenQ recommends Filmmaker mode for SDR content (this automatically activates the WCG feature) to achieve the 100% Rec.709 gamut, I actually preferred the Bright Cinema mode. Turning off the WCG, as it turns out, also bumps up the brightness, so I opted to leave this off. For both movies, I found the color, brightness, and contrast to be good, and in Pulp Fiction, Jules and Vincent’s black-and=white suits popped, and the light from the window in the hallway as they talk about foot massages is nice and clean, too.

I didn’t see a big difference between any of the other picture modes except Bright, which has a noticeable green tinge — I assume it’s meant to be manually tweaked. There are also several Light Source Modes that affect brightness and the strain on the bulb. For the most part, I used the Normal mode, as I found it to be the brightest. SmartEco and Eco mode were very similar – slightly dimmer than Normal — but Eco mode significantly quieted up the projector’s fan.

Whether using the Android TV, Apple TV 4K, or whatever source you prefer, when the HT4550i detects an HDR source, it automatically puts the projector in the corresponding HDR mode (HDR10, HDR10+, or HLG) and adjusts the settings for optimum use, activating and deactivating features such as WCG, Local Contrast Enhancer, and the Light Source Mode to suit.

I watched everything from Avengers: Endgame on Disney+ and The Witcher on Netflix to Game of Thrones on HBO (for HDR10 examples) and The Tomorrow War on Amazon Prime Video for the tone-mapped HDR10+ source, and switched back-and-forth between the Apple TV and the Android TV dongle. First, I’ll say that everything looked incredible, no matter what mode was activated by default. Honestly, for the price, setting one of these up in your house is a no-brainer — it’s an easy path to a killer home theater.

For my HDR10 test with Endgame and GoT, in a dark room, I switched between it and Filmmaker Mode, the latter of which shows off the WCG’s super-accurate colors and skin tones (Thanos was indeed Thanos purple). Like with my SDR tests, I did prefer the image with the WCG filter off for that extra brightness bump, especially when putting GoT’s much-criticized The Long Night episode to the test. The dark scenes were indeed dark, but I could see all the details just fine (Jon Snow fumbling around in the dark killing walkers, the Night King in all his glory). Although the color with the Wide Color Gamut feature on is admittedly better, I didn’t see enough of a difference for me to choose it over the extra brightness.

In HDR10+ through the Android TV dongle, The Tomorrow War, despite being a terrible film, also looked beautifully bright, with more detail, s well as vivid and accurate color — slightly more so than its HDR10 version on the Apple TV. The film does have a good range of fast action scenes that are handled nicely by the HT4550i, and even some blisteringly bright snow sequences at the end. In HDR10+, content defaults to the WCG being off and the HDR Brightness setting being unavailable. And even though you do get some more detail and color accuracy with the WCG on, you guessed it, I still preferred it with it off for that extra brightness, even at the slight sacrifice of some inkiness in the blacks. Maybe it’s just me (BenQ’s reviewer guide likes to suggest the WCG be on a lot), but I like a nice bright image, which is part of why I really like the HT4550i, as it’s so easily tweakable. With well-laid-out menus that make sense, those who dare can take a deep dive into their own calibration, grayscale, color, and other fine-tuning modes for the perfect picture. But for most, the built-in pre-calibration setting proved to be exceptional out of the box.

The bottom line

The BenQ HT4550i may seem daunting for the uninitiated (and due to its $3,000 price), but for a premium LED DLP projector that can turn most medium-sized rooms into an impressive 4K UHD big-screen home theater, it’s easy to set up and surprisingly easy to use. The HT4550i’s blazing 3,200 ANSI-lumens brightness that’s driven by its 4LED DLP light source (with a 20,000-hour life) is excellent in rooms with moderate light and a champ in the dark, to be sure. But the crown jewels of the HT4550i’s specs are its ability to achieve film-industry-accurate 100% DCI-P3 color and the HDR-Pro tech that supports HDR10, HDR10+, and HLG formats for impressive contrast.

But perhaps what is most appealing about the HT4550i is how ready to roll it is out of the box. It’s nearly perfect at the get-go, but offers you the ability to easily tweak a wide range of settings via advanced color settings to tailor it to your room and your preferences, which gives the HT4550i a leg up on cheaper — and even some higher-end — projectors. Plus, even if you don’t have your own streaming device or Blu-ray player to get started with, the included Android TV dongle is easy to install and use.

The HT4550i could also give some laser projectors and multi-chip DLP projectors a run for their money in brightness and price. For some comparisons, you could check out BenQ’s own X3000i 4K gaming projector, which shares many of the same features (including its 4LED  light source and 100% DCI-P3 CinemaColor), but not HDR10+ support, for $1,000 less, and even the Epson EpiqVision LS800 UST an ultra-short throw (UST) 4K laser projector with 4,000 ISO lumens of brightness that costs $3,500.

But with its video quality, ease of use and setup, and piles of adjustable features, it’s worth considering forking over $3,000 for the BenQ HT4550i.

Go ahead and spend the extra $20 on the good Apple TV 4K
Apple TV 4K 2021.

Apple has announced two new versions of the Apple TV 4K. Both are good for all kinds of reasons. Better internals. New features. And prices that are much more likely to be competitive, even if they're still a good bit north of what folks are spending on the likes of Roku and Amazon Fire TV devices.

But two new Apple TV 4K boxes -- and the death of the lower-resolution Apple TV HD -- means you've got a decision to make. Which Apple TV 4K is right for you?

Optoma’s CinemaX 4K laser projectors now have faster response times for gamers
People using the Optoma CinemaX D2 outdoors.

Optoma is expanding its 4K UHD home theater projector line by introducing the CinemaX D2 Series. Optoma says this is an upgrade from the previous CinemaX P2 projector, and the improvements are based on user feedback. The series includes the CinemaX D2, a 4K UHD ultra short throw laser home projector, and the CinemaX D2 Smart, which adds smart TV features courtesy of an included Android TV dongle.
Ultra short throw projectors are ideal for people with limited space in their room as they can cast an image on the screen from small distances. Traditional short throw projectors need at least four feet to eight feet of distance from the screen to be able to produce high-quality images, but not all rooms have this much area to spare.  That's where ultra short throw projectors can help. The CinemaX D2 Series, for example, can cast up to 100-inch images from less than a foot away from the screen. If you increase the distance a bit more, you get up to 120-inch images. 
The CinemaX D2 Series features 3,000 lumens and a 1,800,000:1 contrast ratio, which, oddly, is a bit of a step down from their predecessor, the CinemaX P2 projector, which offers the same brightness, but with a 2,000,000:1 contrast ratio. 

The biggest boost this series offers is an Enhanced Gaming Mode that claims "blur-free visuals and low lag" with the help of its 16ms response time in 4K at 60Hz and 4ms in 1080P at 240Hz. The 30,000-hour life span (same as its predecessor) seems to be slightly higher than other ultra short throw projectors in this price range as well. Both D2 models have three HDMI 2.0 inputs, instead of the P2's double-HDMI 2.0 and single HDMI 1.4 inputs.
