The physical resolution of the projector is 854*480, but it supports the decoding and playback of 1080p. Is the published resolution 1080 or 480?

The physical resolution of the projector is 854*480, which means that the highest resolution of playback is 854*480, which will not be higher than this resolution.

Supporting 1080p decoding and playback means that such high-definition signals can be input, but the output effect will be reduced after decoding and playback, and the picture of 1080p will be compressed to 480. No matter what resolution you enter, it will eventually play at the highest resolution of the current resolution of 854*480.

Differences in projector resolution—

The original resolution of the image projected by the projector is also called true resolution and physical resolution. Physical resolution corresponds to compression resolution, which determines image definition and compression resolution determines the application range of projector. Physical resolution is the resolution of the LCD panel.

On the LCD panel, liquid crystals are divided into grids, and each liquid crystal is a pixel. Then, when the output resolution is 1024 × 768, it means that the LCD panel is divided into horizontal 1024 pixels and vertical 768 pixels.

There are also two common expressions of projector resolution. One way is to use TV lines, and the other way is to use pixels. When expressed by TV cable, its resolution is similar to that of TV, which is mainly provided to match the TV signal connected to the projector.
