Designed for the Micro-Portabel sector, the Qumi Q4 model from Vivitek features 500 ANSI lumens, a native WXGA 1280 x 800 resolution and a contrast ratio of 2500:1. The manufacturer specifies a durability of 30000 hours for the LED light source – equivalent to a usable life of 20.5 years at 4 hours a day. Looking at practical performance, up to 227 cm can be illuminated with 500 ANSI lumens in dark environments. Once daylight is in the room, the image should ideally be no wider than 151 cm. For media input, video signals up to 1080P are supported. Also on board is a local media player that allows reading and playing content directly from storage media. Thanks to MHL support, screen content from mobile devices can be transmitted via cable, including charging power for the device. This model dates back to 2014 and is no longer part of Vivitek's current product range.
