Guides for this projector
How to calculate projector throw distance
Throw distance = image width × throw ratio. First convert the screen diagonal to width (for 16:9, width = diagonal × 0.872), then multiply by the projector's throw ratio. For a 100-inch screen (87 inches wide) and a 1.5 throw ratio: 87 × 1.5 = 131 inches, about 11 feet.
GuidesTrue 4K vs pixel-shift 4K
Native 4K projectors put 8.3 million real pixels on screen; pixel-shift (XPR) projectors flash a 1080p or 2.7K chip 2-4 times per frame to approximate 4K. Native is slightly sharper on fine detail but costs much more; pixel-shift looks 4K to most eyes at normal viewing distance and covers nearly all affordable "4K" projectors.
GuidesProjector ceiling mount height
Mount the projector so its lens lines up with the top of the image when the projector has 0% offset (most do), then fine-tune with lens shift. A 100-inch 16:9 image is 49 inches (124 cm) tall, and the screen bottom usually sits 24-36 inches (60-90 cm) above the floor for seated eye level.
