At 4000 lumens, this projector will display a very bright image even in the lightest of rooms, with the lights on – keeping a safe working environment – but it also has Eco features and will allow you to turn the brightness down if necessary when it is slightly darker. The WUXGA resolution is perfect for connecting to modern laptops and desktop computers via either HDMI, VGA or USB, and will comfortably project videos, presentations and spreadsheets in fine detail. The MHL feature will allow you to present in high definition from your mobile device. The 3 in 1 USB function will allow you to display image, mouse and sound all with one cable! This resolution is higher than 1080p so you will project in great clarity.
