Very high brightness of 4,000 ANSI lumens—great for use in rooms with ambient light.

Strong contrast ratio (~25,000:1) enhances detail, making text and graphics clear and sharp.

Throw ratio of approximately 1.55 to 1.73:1 with a small amount of manual zoom (1.1×) for flexible placement.

Keystone correction (vertical ±40°) helps adjust the image when the projector is not directly centered.

Portable and reasonably lightweight (~3 kg), suitable for moving between rooms or carrying for off‑site presentations.

Built‑in 10W mono speaker provides sound without needing external speakers (good for casual use).

Multiple input options: HDMI, VGA, composite video, audio in/out, USB‑A power output — connectivity suitable for laptops, dongles, media devices.

Uniformity around 75%, ensuring brightness is reasonably consistent across the image.
