Winner: BenQ HT4550i

Installation and Connectivity

BenQ HT4550i Back

In terms of installation and connectivity, both projectors offer versatile options but with subtle differences that became evident during our testing phase. The BenQ HT4550i features a 1.3x zoom ratio and a 2D lens shift, allowing for vertical adjustments up to 60% and horizontal shifts up to ±15%. These features facilitated a relatively easy setup process, even in rooms where the projector had to be placed off-center. Connectivity options include dual HDMI 2.0b ports, a LAN (RJ45) slot, and USB Type-A ports, amongst others. Its built-in Android 11.0 system further smoothens the experience, especially when streaming content.

LS12000 back

The Epson LS12000 takes flexibility a notch higher with its 3-axis motorized lens shift, offering vertical adjustments of -96.3% to +96.3% and horizontal shifts from -47.1% to +47.1%. This makes it an ideal choice for complex installation scenarios. It also boasts dual HDMI 2.1 ports, USB, and LAN connectivity, but lacks a built-in operating system for direct streaming. What stood out during our setup was the powered focus/optical zoom/lens position options in the Epson, providing a level of precision that was notably superior. In summary, while both projectors offer robust installation and connectivity features, the Epson LS12000 comes out ahead in terms of flexibility and precision.

Winner: Epson LS12000

Brightness and Image Quality

During our testing, the area where the BenQ HT4550i truly shined was in its brightness, boasting an impressive 3200 ANSI lumens. Even in rooms with ambient light, the projected image remained vivid and crisp. Coupled with a contrast ratio of up to 2,000,000:1, this projector delivered impeccable black levels and high contrast scenes. The HT4550i’s HDR-PRO technology, including Optimal HDR Tone Mapping and Leading Local Contrast Enhancer, added a level of realism that made movies and games come to life. The device also supports 100% DCI-P3 and Rec. 709 color coverage, providing an authentic cinematic experience.

The Epson LS12000, although less bright at 2,700 lumens for both color and white brightness, compensated with its advanced laser array light source and Epson ZX Picture Processor. The 2,500,000:1 contrast ratio and full 10-bit HDR color processing were notably powerful, providing an extraordinary depth of detail in darker scenes that felt almost three-dimensional. Epson’s unique 4K PRO-UHD pixel shifting technology further enhanced the image quality, making it incredibly sharp and vibrant. While the BenQ HT4550i wins in terms of sheer brightness, the Epson LS12000 excels in delivering nuanced colors and deeper blacks, offering a richer overall image quality.

The Epson LS12000, while providing an immersive gaming experience with its 4K PRO-UHD pixel shifting and 2,500,000:1 contrast ratio, didn’t perform quite as well as the BenQ HT4550i in terms of input lag. While exact figures for input lag weren’t readily available, we did notice a slight delay during intense gaming situations. However, the 120 Hz refresh rate on the LS12000 contributed to smoother motion and visuals, and for gamers who prioritize image quality and color accuracy over speed, this projector is an excellent option. In summary, if your primary focus is competitive gaming, the BenQ HT4550i is the better choice, but if you’re after a more cinematic gaming experience, the Epson LS12000 holds its ground admirably.

Smart Features

Smart features have increasingly become a defining aspect of modern projectors, and in our hands-on experience, the BenQ HT4550i did not disappoint. It runs on Android 11.0 and features a user-friendly interface, making it easy to access streaming services like Netflix and Prime Video. The built-in Wi-Fi supports 2.4G and 5G bands, while the Bluetooth 5.0 allows seamless connection to external speakers or headphones. We particularly enjoyed using the AirPlay and Google Cast options for wireless projection, making it incredibly convenient to share content from our mobile devices.

The Epson LS12000, on the other hand, lacks a built-in OS, which means you’ll need to connect an external device for smart functionalities. While this may be seen as a disadvantage, it also allows you the flexibility to choose your preferred streaming device. The projector does offer multiple connectivity options, including dual HDMI 2.1 ports with eARC/ARC support, but falls short on the wireless connectivity front. It has no native Bluetooth or Wi-Fi options for direct streaming or audio output. Overall, if built-in smart features are a priority, the BenQ HT4550i has a clear edge, while the Epson LS12000 provides more room for customization through external devices.

Winner: BenQ HT4550i

Sound Quality

When it comes to sound quality, projectors often take a backseat to external sound systems. However, we were pleasantly surprised by the BenQ HT4550i’s inbuilt 5W chamber speaker. Although not a substitute for a full-fledged home audio system, it did a commendable job in delivering clear and well-balanced audio for casual viewing. The projector also supports HDMI Audio Return and Dolby Atmos through eARC, adding another layer of sonic depth when connected to a compatible sound system.

In contrast, the Epson LS12000 does not come with built-in speakers, which means an external sound system is mandatory. During our testing, we hooked it up to a Dolby Atmos-enabled soundbar via the HDMI eARC port and found that the projector managed the audio pass-through flawlessly, delivering rich and immersive sound. While the absence of an integrated speaker could be seen as a limitation, it also suggests that the LS12000 is designed for those who prefer to tailor their audio experience. So, if you’re satisfied with basic, built-in sound for casual use, the BenQ HT4550i has you covered; but for audiophiles who insist on top-tier audio, the Epson LS12000 offers the flexibility to curate your ideal setup.

Winner: BenQ HT4550i

BenQ HT4550i vs Epson LS12000: The Verdict

After rigorous testing and side-by-side comparisons, it’s clear that the BenQ HT4550i emerges as the winner in this matchup. While both projectors offer exceptional image quality and an array of advanced features, the BenQ HT4550i distinguishes itself with its built-in smart functionalities, Android OS, and a more versatile range of connectivity options. Its user-friendly interface and integrated speaker make it a more complete, plug-and-play solution for those who seek both convenience and high-quality projection.

That being said, the Epson LS12000 is by no means a slouch and would be an excellent choice for those who already have a dedicated external streaming device and sound system. Its 4K PRO-UHD pixel shifting technology and laser array light source ensure a breathtaking visual experience. However, when weighing all the factors, including price, ease of use, and versatility, the BenQ HT4550i offers a more well-rounded package, thereby making it the ideal choice for the majority of home theater enthusiasts.
