With television, the formats became 4:3 with standard definition and later 16:9 with high definition, which at 1.78:1 was a close match to 1.85:1 widescreen cinema. Note: many say 2.39:1, 2.40:1 (“two-four-oh”) or 2.35:1, but nowadays these typically all refer to the same 2.39:1 aspect ratio.
Subsequently, one may also ask, what is a good resolution for projector?
Resolution is simply the number of pixels (or "picture elements") the projector uses to create the image. If a projector's native resolution is 1024 x 768 (XGA), that means that the actual number of physical pixels on the display device is 1024 x 768.
What is the best aspect ratio?
Aspect ratio is the relationship of the width of a video image compared to its height. The two most common aspect ratios are 4:3, also known as 1.33:1 or fullscreen, and 16:9, also known as 1.78:1 or widescreen. (Larger aspect ratio formats are used in the motion picture industry.)
What is the throw ratio of a projector?
Throw distance is the distance from the tip of the projector's lens to the screen. For any given projector, the width of the image (W) relative to the throw distance (D) is know as the throw ratio D/W. So for example, the most common projector throw ratio is 2.0.
