As a projector for the Game-Portabel sector, the PTVDISPLAY E400 is equipped with 96 ANSI lumens, a WVGA 800 x 480 resolution and a contrast of 1000:1. Thanks to LED technology, the projector is rated for a lifespan of up to 30000 hours, which translates to 20.5 years with 4 hours of daily use. To ensure a rectangular image even with asymmetrical placement, the projector includes digital keystone correction for both the horizontal and vertical axes. Because the manufacturer specifies brightness in lumen specifications, we have determined an ANSI lumen value for better comparability. Looking at practical performance, up to 100 cm can be illuminated with 96 ANSI lumens in dark environments. Once daylight is in the room, the image should ideally be no wider than 67 cm. In terms of video signals, the device processes resolutions up to Full HD 1080P. This is a discontinued model that is no longer officially distributed by PTVDISPLAY.
