introduction to the Acer H7550BD. The home cinema DLP projector has an HDTV 1920 x 1080 resolution and a contrast of 16000:1. The lamp life is specified by the manufacturer as 4000 hours, which converts to over 5.5 years at 2 hours per day. The projector can illuminate a picture width of up to 556 cm well thanks to the 3000 Ansi lumens. In room light, however, the picture width should ideally be less than 371 cm. The HDMI MHL (Mobile High-Definition Link) port allows 1080p / 60 Hz image mirroring (screen mirroring) to be transmitted from a smartphone while it is being charged at the same time via the connection. The projector can also play 1080P and 3D without any problems.
