the acer k11, weighing only 1.3 lb., is the smallest projector to offer a brightness of 200 lumens. because it?s compatible with the power adapter of acer notebooks, users needn?t bother packing an adapter for each device. alternatively, they can simply carry the k11 along with a usb drive or sd card to display whatever they want to share without a notebook or video player. the acer k11 can also be used to project videos and photos from an ipod or iphone using an appropriate apple-certified a/v adapter. native resolution: svga (800 x 600) maximum resolution: sxga (1280 x 1024) maximum wide resolution: wxga+ (1440 x 900) contrast ratio: 2000:1 brightness - ansi lumens: 200 standard projection lens: f = 2.2, f = 19.5mm, manual focus projection screen size: 15" (38cm) 80" (203cm) projection distance: 25" (64cm) 134" (340m) i/o connectors: usb type a, composite video/audio 3.5mm four-pin mini-jack, hdmi (video, audio, hdcp), analog/rgb component video (d-sub), sd (sdhc) data compatibility: wxga+ (1440 x 900), wxga (1280 x 800, 1280 x 768), sxga (1280 x 1024), xga (1024 x 768), svga (800 x 600), vga (640 x 480)
