Most listings include HDMI or micro‑HDMI; some models also list USB ports and standard AV connectors. A few entries mention optical audio, component audio, or other audio outputs.

Many listings offer keystone correction (manual, ±15° or auto), adjustable or electronic focus, and in some smart models auto‑focus. Several also include screen zoom or on‑device keystone tools to correct image distortion.

Lumens ratings vary widely across listings — examples include 70, 100, 140, 220, 230, 250, 3,450 and 8,000 lumens. Stated maximum or native resolutions include 800×480, 1280×720, 1920×1080, 1080×1080 and 3840×2160.

Reported lifespans vary; examples include "20,000 hours", "30,000 hours", "50,000 hours", and one listing that gives "2 years" instead of an hours value.

Descriptions list Wi‑Fi mirroring and dual‑band 2.4/5 GHz wireless, Wi‑Fi 6 support in some models, built‑in mirroring protocols (Miracast, AirPlay, DLNA), Bluetooth (e.g., Bluetooth 5.1/5.2), and compatibility with external streaming sticks or smart hubs.

Higher‑end descriptions list features such as "Triple Laser Technology", "4K AI Upscaling", "HDR10+", expanded color‑volume claims (for example "154% color volume in the DCI‑P3 color space"), "Vision Booster", and "Ultra Bright Laser."
