Projector guides.

To choose a portable projector, write a one-page room brief first: usable wall width, lens-to-wall distance, room light, number of viewers, source devices, power and whether the projector will move.

Native resolution is the fixed pixel grid a projector uses to draw its image.

Choose a battery projector when you will present where a socket is uncertain or the session is short and mobile.

Room light and image size decide how bright a projector looks, not the lumen rating alone.

Check five projector connections before you buy a portable projector: the socket your picture arrives on, the route the sound takes out, whether its USB ports can read a file off a stick, whether it takes a cable to your network, and what its wireless casting line actually promises.

Set up a classroom projector by checking the whole teaching space, not the projector alone: map the image area and the seats, test in the room's normal light, work out the lens distance from the throw ratio, prove a main and a fallback source, project real lesson material, then record the working setup.

A 1.2:1 throw ratio means the projector's lens sits 1.2 metres from the screen for every metre of image width.

A classroom projector setup checklist covers eight checks to run before each lesson: a stable surface, clear vents, power connected and cables out of walkways, the right input selected, the image aligned and focused, real lesson content on screen, room lights set as in class, and the result recorded.

Neon+ states a 365-day local warranty from purchase for manufacturing defects, with one-to-one replacement for qualifying faults and no cash refunds.

ANSI lumens, native resolution, throw ratio, contrast, HDMI and more, with the V6 as the worked example.

From the RM799 Q1 to the 1600 ANSI lumen X5 and X5 Plus, each with its published specification sheet.
