While it has built-in speakers, connecting external audio equipment is recommended for an immersive sound experience.

Optoma UHZ50

The Optoma UHZ50 is a high-performance 4K UHD projector that delivers exceptional visual quality. With native 4K resolution, it offers incredibly sharp and detailed images, surpassing the clarity of Full HD projectors. It supports HDR10 and HLG content, ensuring rich colors and deep contrast for a truly immersive cinematic experience. This projector features a laser light source, providing long-lasting brightness and color accuracy, while eliminating the need for frequent lamp replacements. The UHZ50 is equipped with multiple HDMI inputs and integrated speakers, making it versatile and easy to set up. Overall, it’s an excellent choice for those seeking a premium home theater projector.


Design and Build Quality

Let’s start with the aesthetics. The BenQ HT4550i and the Optoma UHZ50 both feature sleek and modern designs that will complement any home theater setup. The BenQ HT4550i boasts a compact and elegant white chassis with a prominent lens and control buttons on the top. On the other hand, the Optoma UHZ50 sports a glossy black finish with a central lens and a control panel on the rear.

In terms of build quality, both projectors feel solid and well-constructed. However, the BenQ HT4550i stands out with its attention to detail and premium finish. It exudes a sense of craftsmanship that sets it apart in terms of aesthetics.

Image Quality

Now, let’s talk about what really matters – the image quality. The BenQ HT4550i and the Optoma UHZ50 are both 4K UHD projectors, which means they deliver stunningly sharp and detailed images. However, there are some differences in how they achieve this.

The BenQ HT4550i uses a single DLP (Digital Light Processing) chip with XPR technology to achieve 4K resolution. This technology rapidly shifts each pixel to create the illusion of 4K resolution. The result is impressive, with crisp and clear images that are rich in detail. The color accuracy and brightness are also noteworthy, making it an excellent choice for both movie nights and gaming sessions.

On the other hand, the Optoma UHZ50 utilizes a traditional 3LCD chip with a native 4K resolution. This means it doesn’t rely on pixel-shifting techniques to achieve 4K, and the image quality is inherently sharp and true to the source material. Colors are vibrant and accurate, and the UHZ50 offers impressive brightness levels, making it a fantastic choice for well-lit rooms.

Contrast and Black Levels

One crucial aspect of image quality in a projector is contrast and black levels. Deep blacks and good contrast ratios can significantly enhance the viewing experience. The BenQ HT4550i uses a dynamic iris to improve contrast, and it does a commendable job of producing deep blacks and bright whites. However, it might not be as effective as some high-end projectors in this regard.

The Optoma UHZ50, on the other hand, employs laser technology to achieve excellent contrast levels. The dynamic black feature adjusts the laser’s output to enhance dark scenes, resulting in deeper blacks and improved shadow details. This is where the UHZ50 shines, and if you’re a fan of watching movies with lots of dark scenes, you’ll appreciate its performance.

Throw Ratio and Zoom

When setting up a projector, the throw ratio and zoom capabilities are important factors to consider. The BenQ HT4550i has a slightly longer throw ratio, which means it needs more distance to project a specific screen size compared to the Optoma UHZ50. This might be a consideration if you have limited space.

The HT4550i offers both horizontal and vertical lens shift, which allows for more flexibility in projector placement. On the other hand, the UHZ50 has a limited zoom range and no lens shift, so you’ll need to be more precise when positioning it.

Connectivity and Audio

In the era of smart homes, connectivity options are crucial. Both projectors come equipped with a variety of ports, including HDMI, USB, and audio outputs. The BenQ HT4550i takes it a step further by offering wireless capabilities through its built-in Android TV system, allowing you to stream content directly from popular apps like Netflix and YouTube without the need for external devices. The integrated 5W speakers are decent but may not provide the immersive audio experience you desire.

The Optoma UHZ50, on the other hand, lacks the built-in smart features of the HT4550i but compensates with a more robust audio system. It features a powerful 10W speaker, which can fill a small to medium-sized room with clear and loud sound. However, for a true home theater experience, you might still want to invest in an external sound system.

Gaming and Input Lag

For gamers, input lag is a crucial factor to consider. The BenQ HT4550i offers a game mode that reduces input lag, making it a suitable choice for gaming. While it may not be as low as some dedicated gaming projectors, it provides a responsive gaming experience.

The Optoma UHZ50, however, falls a bit short in this department, with slightly higher input lag. Gamers who prioritize low latency may find the HT4550i more appealing.

Price and Value

Last but not least, let’s talk about the price point. The BenQ HT4550i tends to be priced slightly higher than the Optoma UHZ50. However, the price difference can vary depending on promotions and availability. When evaluating the price, consider the specific features and performance aspects that matter most to you.


In conclusion, both the BenQ HT4550i and the Optoma UHZ50 are excellent 4K UHD projectors that can elevate your home theater experience. The choice between them ultimately comes down to your specific needs and priorities.

If you value a sleek design, built-in smart features, and lower input lag for gaming, the BenQ HT4550i might be the better choice for you. Its impressive image quality, color accuracy, and flexibility in placement make it a strong contender in the mid-range projector market.

On the other hand, if you prioritize outstanding contrast and black levels for a cinematic experience with excellent audio quality, the Optoma UHZ50 is worth considering. Its native 4K resolution and laser technology excel in creating vivid, lifelike images with deep blacks.

In the end, both projectors have their strengths and weaknesses, so carefully evaluate your preferences and budget to determine which one suits your home theater needs best. Regardless of your choice, you’re in for a cinematic treat with either the BenQ HT4550i or the Optoma UHZ50. Happy viewing!
