Most projectors used nowadays are video projectors, which are the digital counterparts to their analog predecessors, and are capable of producing images from an electrical signal, rather than shining light through an image medium. These older methods consisted primarily of a light source and transparent slides to alter the light from the source as it travelled to the projected surface, producing the desired image. The principle of camera obscura, showing up in Chinese texts around 400 BCE, is another early example of projected images, as it uses the light bouncing off of an actual object as the source to produce an inverted image when shined through a pinhole.Įarly projectors, like the slide projector or overhead projector, were only capable of projecting a single image at a time, which would have to be manually changed or manipulated to change the projected image.

Onn also claims 500-nit HDR brightness for this TV, but during testing I measured HDR peaks closer to the low 400s, coupled with black levels that were overly bright on occasion.
