LV7245 beamer
With XGA resolution and powerful 2500 lumens brightness, the LV-7245 is ideal for projecting in large meeting rooms and boardrooms. Delivers high impact presentations without the high price tag. The LV-7245 projects images at XGA resolution (1024 x 768 pixels) for razor sharp definition, extendable with high-quality compression to UXGA (1600 x 1200). With powerful 2500 lumens you get bright, crystal clear presentations without having to darken the boardroom. With 300:1 contrast ratio, images are super crisp with brighter whites, darker blacks and richer colors. A DC lamp and progressive scan technology ensure that projected images remain smooth, steady and flicker-free. Quiet Mode's near-silent 30dBA operation suppresses fan hum to keep audience attention fixed on your presentation. Running the projector in Quite Mode increases lamp life to 3000 hours. The projector's wide-angle 1.2x zoom lens lets you project large images from short distances - great when positioning the projector close to the front of the room. Canon's Automatic Vertical Keystone Correction compensates for any picture distortion that occurs when the projector is not perpendicular to the screen. The LV-7245 automatically detects any projector tilt and compensates to a maximum angle of ±30 degrees. The LV-7245 is ready for use nine seconds after you turn on the power. Once you've made your pitch, cool-down takes just 30 seconds. Once connected to a PC or other video source, the LV-7245 automatically detects the signal type and resolution and adjusts itself accordingly, without the need for manual intervention. RGB output allows connection to an external prompt monitor, so you never have to turn your back on your audience. The Remote Control has a USB infrared receiver that can control the mouse cursor of your laptop from up to seven meters away. Because you can't always project onto a white wall, Wall Color Correction preserves the natural colors of an image when projecting onto colored surfaces. Choose from seven different wall color modes, including Blackboard mode.
