Many models include built-in speakers or Hi‑Fi speakers. Several also list Bluetooth audio (including two‑way Bluetooth and Bluetooth 5.x versions) and advertise enhanced surround or 360° sound. The product descriptions vary in detail, but built‑in speaker and Bluetooth support are the most common audio features.

Adjustments vary by model: some offer auto‑focus and automatic keystone correction (commonly ±15°), others provide manual or adjustable focus, and a few include electrical/electronic focus or automatic leveling with wider auto‑keystone ranges. Product listings use a mix of manual, motorized, and automated correction methods.

Review summaries generally report easy setup and simple operation, frequently noting plug‑and‑play convenience, straightforward installation, and helpful keystone correction that speeds up initial alignment.

The listings include several resolutions: 1920×1080 (also shown as 1080×1920 in one listing), 1280×720, 1080×1080 and 800×480. Note that some entries show portrait-oriented or square variants of common resolutions.
