Model Overview

The basic data of the Epson Lifestudio Flex EF-73 includes 1250 ANSI lumens, a resolution of UHD (4K2K) 3840 x 2160 as well as a contrast of 5000000:1. As an LED projector, the spec sheet indicates a lifespan of 20000 hours. With four hours of daily operation, this corresponds to a period of 13.7 years.
To ensure a rectangular image even with asymmetrical placement, the projector includes digital keystone correction for both the horizontal and vertical axes.
Looking at practical performance, up to 359 cm can be illuminated with 1250 ANSI lumens in dark environments. Once daylight is in the room, the image should ideally be no wider than 239 cm.
Regarding signal processing, the model is compatible with incoming 1080P content and 4K. Additionally, thanks to Google TV, the model is network-capable and can be used without external playback devices. The integrated Google Assistant ensures comfortable operation, allowing the projector to be controlled via voice commands. Furthermore, the model is Bluetooth-enabled, allowing audio signals to be sent wirelessly to external speakers. Since the projector supports Chromecast screen mirroring, video signals can also be streamed wirelessly from the end device.
In the specifications, the operating noise is listed at a mere 28 decibels, indicating very quiet cooling.
