Acer projector X1228Hn with resolution of 1024 x 768 pixels.

The projection technology is the way in which the light from the projector's lamp is converted into an image to be projected onto a surface through the lens. This particular projector uses DLP (DMD) technology and its lamp is regular type, which has higher brightness and shorter lifespan than LED lamps.
This specific technology takes its name from the initials of the words Digital Light Processing, it is the most widespread projection technology and there are projectors with one or three DLP chips. The image is created when the light from the projector lamp passes through a rotating color wheel and is reflected by a chip that has hundreds of thousands of microscopic mirrors, each corresponding to a pixel. This chip is called DMD (Digital Micromirror Device). They are suitable for well-lit spaces, such as classrooms or conference rooms, and have good color performance.

The brightness is a very important characteristic that is taken into account, along with the projection distance and maximum diagonal you want to achieve, for selecting a projector. This specific one has a brightness of 4800 ANSI Lumens, which indicates how much light the projector can deliver on a specific surface size. The general rule suggests that the "brightest" projectors should be preferred in spaces with sufficient light or multiple light sources, while the "darker" ones should be preferred in dark spaces.

It is equipped with Wi-Fi, so you can connect wirelessly to your local network and stream a program online or download software updates.
