According to Acer, the P1257i model provides 4500 ANSI lumens, a contrast ratio of 20000:1 alongside a XGA 1024 x 768 resolution. The manufacturer rates the durability of the included lamp at 5000 hours, achieving a lifespan of 6.8 years when used for 2 hours a day. Regarding projection size, the value of 4500 ANSI lumens allows for an image width of up to 584 cm in darkened environments. In rooms with ambient light, the image width should be correspondingly reduced to a maximum of 389 cm. Regarding signal processing, the model is compatible with incoming 1080P content as well as 3D. Since the projector supports Miracast and Ezcast screen mirroring, video signals can also be streamed wirelessly from the end device. Since entering the market in 2022, production has been discontinued; the manufacturer no longer actively offers the model.
