Verdict

The ASUS B1M is an ultra-portable DLP projector designed for mobile professionals, featuring a 700-lumen LED light source and a native WXGA (1280 x 800) resolution. It is characterized by its compact, lightweight design weighing just 900g and a short-throw ratio of 0.9:1, which allows for a 51-inch projection from only 1 meter away. Main pros include a long-lasting mercury-free lamp life of up to 30,000 hours, wireless streaming capabilities via a Wi-Fi dongle, instant on/off functionality, and dual 2W SonicMaster speakers for PC-free multimedia playback through its built-in SD card reader and USB port. However, notable cons include its relatively low brightness for well-lit rooms, the lack of an internal battery necessitating a power source, and the use of diamond-shaped pixels that can make small text appear less sharp compared to traditional square pixels.
