Introduction

The HY-400 Smart Video Projector promises a cinematic experience wherever you go. With its compact size, impressive 5000 lumens of brightness, and Android 11.0 operating system, it’s designed to be a versatile and convenient home theatre solution. But does it deliver on its promises? I spent several weeks putting the HY-400 through its paces to find out.

Key Features

The HY-400 boasts a compelling array of features. Its 5000 lumens brightness ensures clear images even in moderately lit rooms. The Android 11.0 operating system provides access to a wide range of streaming apps and other functionalities directly on the device. Connectivity options include dual-band Wi-Fi 6 and Bluetooth 5.2, while a built-in 5200 mAh battery offers up to 3 hours of cordless use. The inclusion of MEMC technology helps reduce motion blur in fast-paced content, and the optically coated glass lens contributes to better image clarity. The projector also supports screen sizes up to 150 inches and can be easily mounted on a tripod.

Performance & Image Quality

In terms of image quality, the HY-400 delivers a surprisingly sharp picture, especially considering its size and price point. The 1080P (1280×720) native resolution is adequate for most uses, though the advertised 4K resolution is upscaled rather than native. Colors are vibrant and generally accurate, and the 5000 lumens proved sufficient for viewing in a room with ambient light. While not as bright as dedicated home theatre projectors, it held its own surprisingly well. The built-in speakers provide adequate sound, though connecting to external speakers is recommended for a more immersive audio experience. The Android 11.0 interface was responsive and intuitive, with easy navigation. The remote was also well designed and easy to use. The battery life proved accurate to the manufacturer’s claims, providing a solid 2.5 to 3 hours on a full charge.

However, some minor issues were observed. In dark scenes, some minor light leakage was noticeable around the edges of the image. Sharpness can suffer slightly at the maximum projection size. The fan can be a little noisy at times, which might be distracting in quieter environments.

Pros & Cons

• Pros: Bright image, portable design, Android OS, good battery life, versatile connectivity options, relatively affordable.
• Cons: Fan noise can be noticeable, minor light leakage, 4K upscaling rather than native, sharpness can decrease at maximum projection size.

Final Verdict

The HY-400 Smart Video Projector is an excellent choice for those seeking a portable and versatile projector for home use or on-the-go entertainment. Its impressive brightness, convenient features, and user-friendly interface make it a compelling option. While it has some minor drawbacks, its strengths significantly outweigh its weaknesses, making it a worthwhile purchase for most users. I would definitely recommend the HY-400 for its excellent balance of features, performance, and price.
