Multimedia Projectors LV-7240
The LV-7240 offers bright, high contrast projection without blowing the budget. A wide-angle lens and Quiet Mode deliver a big picture without distracting fan noise, even in the smallest meeting room.
XGA resolution
The LV-7240 projects images at XGA resolution (1024 x 768) for razor sharp definition, extendable with high-quality compression to UXGA (1600 x 1200).
Super-bright projection
With a powerful 2100 lumens you get bright, crystal clear presentations without having to darken the meeting room.
Vivid images
With 300:1 contrast ratio, images are super crisp with brighter whites, darker blacks and richer colours. A DC lamp and progressive scan technology ensure that projections remain smooth, steady and flicker-free.
Quietly economical
Quiet Mode's near-silent 30dBA operation suppresses fan hum to keep audience attention firmly fixed on your presentation. Running the projector in Quiet Mode increases lamp life by up to 50%, helping you keep costs down.
Optical zoom
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.
Keystone correction
Automatic Vertical Keystone Correction compensates for picture distortion that occurs when the projector is not perpendicular to the screen. The LV-7240 automatically detects tilt angle and compensates to a maximum angle of 30 degrees.
Fast start-up and shutdown
With 9 second start-up, the LV-7240 springs into action, ready for your presentation. Once you've made your pitch, cool-down takes just 30 seconds.
Automatic signal recognition
As soon as it's connected to a PC or other video source, the LV-7240 automatically detects the signal type and resolution and adjusts itself accordingly, without need for manual intervention.
RGB Out and Remote Control
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 7 metres away.
Project onto any background
Wall Colour Correction preserves the original image colours when projecting onto coloured surfaces. Choose from Blackboard Mode or six different wall colour modes.
