What is the difference between 720p, 1080p and 4K resolution?
These resolutions refer to the number of pixels that make up the image. 720p is HD (1280x720 pixels), 1080p is Full HD (1920x1080 pixels), and 4K is Ultra HD (3840x2160 pixels), offering more detail and clarity.
Do I need to use a special projection cloth or can I project the image on a plain wall?
Although you can project onto a plain white wall, using a special projection cloth improves image quality, especially in terms of contrast and sharpness.
