The problem of diamond pixels and square pixels we can start with the principle of projector imaging: If the projector wants to project a picture, it needs to convert the digital signal of the video content into a picture projected by the projector. In general, the current video screen is a square pixel screen, that is, if the projector is a square pixel, then the video is also a square pixel, and you only need to straight out the screen.
But if the projector is a diamond-shaped pixel, which does not match the video pixel, in order to ensure that the projection result does not deform, then an additional step of "interpolation" is required to be added to the projector to change the square pixel of the video into a diamond-shaped pixel suitable for the projector. At this time, the physical resolution of the projector may be reduced during the interpolation process, and the picture may be blurred. This is why some text is not clearly displayed on diamond pixels.
In conclusion, the square shape is good, and the resolution is the same, but the difference between the rhombic pixels and the actual pixels is very large, so the low projection quality will say the benefits of the rhombus, which is actually deceiving.
