ultra high definition projector

Brightness varies widely across models: examples include very low portable values (around 160 lumens), common midrange figures (about 700–1,500 lumens), higher home-theater levels (2,000 and 3,450 lumens), and an outlier listed at 8,000 lumens.

Throw ratios and placement vary by model: one spec lists a 1.2:1 throw ratio (covering roughly 40" to 200" screens), while an ultra-short-throw example requires about 4.4 inches from the wall for a 100" screen and about 9.4 inches for a 130" screen.

Portable models include compact, lightweight designs (examples show weights around 2.2–3.5 lb and pocket-sized dimensions). Some list built-in rechargeable batteries (one cites a 7,000 mAh battery with up to about 2.5 hours of playback) and support power-bank charging.

Most list 3840 × 2160 (true 4K). Several also note native 1080p support or 4K decoding capability, while a few product details show lower-resolution values for specific modes.

Light sources include laser (including triple-laser) and LED. Reported lifetimes in the specs include about 20,000 hours, 50,000 hours, 10,000 hours, and one entry shown as 3.42 years.

Typical setup features include auto-setup or autofocus, motorized/electric focus, keystone correction (examples show ±15° and automatic vertical correction), and zoom controls to achieve a sharp, rectangular image quickly.
