overhead video projectors

The set includes a mix of resolutions. Common values shown are WXGA (1280×800) and Full HD (1920×1080); some models also list rotated/oriented variants such as 1080×1920. Check individual listings for other or nonstandard resolutions.

Many models use HDMI as the primary wired input and also include USB and 3.5 mm audio ports. Several listings offer wireless features such as dual‑band Wi‑Fi, Bluetooth, and wireless screen‑mirroring. Check each product page for the exact wireless standards and supported protocols.

Many models include alignment and correction features such as vertical keystone (and auto vertical correction), auto keystone or picture‑skew sensors, optical zoom, multi‑corner (4‑corner) adjustment, and horizontal/vertical keystone. Some also support 360° or portrait projection for flexible installation.

The set includes different light technologies: explicit laser phosphor/laser models, DLP lamp‑type projectors, and units that reference long‑lasting LED light sources. Check each listing to confirm the exact light‑source type and rated life.

Weights vary from very lightweight mini units around 1–3 pounds to larger installation models around 6–7 pounds, so the set includes both handheld/portable options and heavier models better suited for fixed installation. Verify the listed weight for any model you plan to carry or mount.
