The listings include both native 4K models (for example SXRD native 4K panels) and models that support 4K via upscaling or proprietary 4K processing (often labeled 4K PRO‑UHD). Smaller, portable units may support playback of 4K video even if their native panel resolution is lower.
Brightness varies widely across models. Examples from the listings include 1,000 lumens, 2,000 lumens, 3,450 lumens and 8,000 lumens, reflecting everything from compact units to high‑output home‑theater and installation projectors.
Many higher‑end models use laser light engines that offer long service life. The listings show bulb‑life figures such as about 20,000 hours and up to 50,000 hours, depending on the model and light source.
Some projectors list native 4K resolution (3840 × 2160). Other models—particularly smaller or portable units—have lower native panels (examples in the listings include 1080 × 1080 and 1080 × 720) while still supporting 4K playback via processing or upscaling.
Built‑in audio varies from small 3W Hi‑Fi speakers in compact units to larger onboard stereo or multi‑channel systems in home‑theater models. The listings include examples such as modest integrated speakers and more powerful setups with outputs up to around 40W, sometimes developed in partnership with third‑party audio brands.
Portability ranges from very lightweight mini models to heavier home‑theater units. Example weights in the listings include 1.4 lb, 3 lb, 8.8 lb, 10.23 lb, 25.6 lb and 28 lb, reflecting pocketible and installation‑style designs.
The listings describe freestanding (portable) placement, fixed installation mounting (ceiling or bracket), and ultra‑short‑throw placement that sits inches from the wall to produce large images without ceiling mounting.
