Projector Technologies
LED projectors offer long lamp life (20,000+ hours), instant on/off, and lower power consumption. LCD projectors provide better brightness and color accuracy at lower cost. DLP (Digital Light Processing) offers sharper images and better contrast. Laser projectors deliver the best color and brightness but cost more. For home use, LED is the most popular and practical choice.
Brightness and Resolution
Brightness is measured in ANSI lumens: 200-500 for dark rooms, 500-1000 for ambient light, 1000+ for daylight viewing. Resolution options: 720p (HD, budget), 1080p (Full HD, sweet spot for movies), 4K (Ultra HD, premium). Native resolution matters more than supported resolution - a 1080p projector accepting 4K input still outputs 1080p. Many portable projectors offer 720p with good-enough quality for casual use.
Projection Size and Distance
Most projectors can display 30-200 inch images. Throw ratio determines distance needed: standard throw (1.5-2x screen width), short throw (0.5-1x, ideal for small rooms), ultra-short throw (0.2-0.3x, sits right below the screen). Calculate your room size: for a 100-inch screen with standard throw, you need about 8-12 feet distance. Keystone correction helps align the image when projector is not centered.
Smart Features and Connectivity
Many modern projectors run Android TV with built-in apps (Netflix, YouTube, Prime Video) and Wi-Fi. Key ports: HDMI (for gaming consoles, streaming sticks), USB (play media from drives), and audio output (3.5mm or Bluetooth for external speakers). Built-in speakers are adequate for casual use but external speakers are recommended for movies. Look for Bluetooth and screen mirroring (AirPlay/Miracast) for wireless phone projection.
