SR450H features a 3.5″ LCD with native 1080P resolution and a brightness of 350 ANSI lumens. Though its contrast ratio is 600:1, the image quality benefits from a high 72% brightness uniformity, providing a more evenly lit screen edge to edge.
Its throw ratio of 1.16:1 allows projection from 40″ to 120″, with a best result at 60 inches from 1.55 meters, making it great for desks, small rooms, or compact installations.
Designed with a sealed optical engine, the SR450H prevents dust intrusion and maintains long-term image clarity. It uses a patented heat/cold air exchange system and DC wind reverse flow to ensure consistent performance.
Despite its power, it operates below 30 dB, offering silent operation ideal for bedrooms or shared workspaces.
The SR450H includes:
Auto focus
Auto keystone correction
Auto obstacle avoidance
Auto side throw
Auto input switching
Choose from Linux OS or Android OS depending on your needs. Both systems support dual-band Wi-Fi, Bluetooth 5.4, and an air mouse remote for seamless navigation.
This model comes in Rose Pink, Midnight Blue, Classic White, Ivory White, and Obsidian Black, and measures 238 × 212 × 178 mm — slightly larger than the SR400H, offering more internal space for cooling and light distribution.
