proyector hd 4k

The listings show a range of reported resolutions. Examples include 1080 × 1080, 1080 × 720, 1080 × 1920, and native 4K at 3840 × 2160. Some models list native 4K while others list maximum or supported resolutions—check each product to confirm whether a resolution is native or achieved via scaling/upscaling.

Brightness values vary widely: examples in the results include 1,500 lumens at the low end and up to 8,000 lumens at the high end, with several models in the 2,000–3,450 lumen range.

Some models include built-in smart platforms with streaming apps and voice-assistant support; others rely on external devices (streaming sticks/boxes) or use screen-mirroring for app access. Check each listing for phrases like “built-in apps,” “voice control,” or notes on compatibility with external streaming devices.

Listings show laser and LED light sources. Reported lamp-life entries include values such as “20,000 Hours,” “50,000 Hours,” and a listing expressed as “3.42 Years”; some product pages do not indicate bulb life. Verify the listed hours for each model when comparing longevity.

Projection sizes and throw distances vary widely. Portable models list short optimal distances (examples: 1.64–11.48 ft) and screen sizes up to about 150", while larger models list much longer maximum distances (examples given: maximum distance 100 ft or projection claims up to 200"). Check each product’s listed throw distance and maximum screen size for exact specs.

Listings include standard/medium throw ratios (for example a 1.2:1 throw ratio) and ultra‑short‑throw designs. Ultra‑short‑throw examples specify very short wall distances (examples: about 8.3 inches for a 90" image and 14.9 inches for 120"; another lists 4.4 inches for 100" and 9.4 inches for 130").

Listings indicate either freestanding or fixed‑installation mount types; some entries explicitly show “Mount Type: Freestanding” while others list “Mount Type: Fixed Installation.”
