According to Aurzen, the Roku TV E1R model provides 300 ANSI lumens, a contrast ratio of 1500:1 alongside a HDTV 1280 x 720 resolution. The LED unit of this model is rated for up to 30000 hours of runtime, covering an estimated 20.5 years based on a 4-hour daily runtime. Looking at practical performance, up to 176 cm can be illuminated with 300 ANSI lumens in dark environments. Once daylight is in the room, the image should ideally be no wider than 117 cm. Additionally, a built-in ambient light sensor measures the room lighting and automatically adjusts the projection settings. For media input, video signals up to 1080P are supported. Furthermore, the model is Bluetooth-enabled, allowing audio signals to be sent wirelessly to external speakers. Thanks to support for Miracast and Airplay, screen content can also be cast wirelessly from a smartphone, tablet, or PC to the screen.
