ASUS’ new G51J 3D laptop offers a full-resolution 3D display which will make games leap right out of its screen
With 3D movies currently taking the cinema box office by storm, isn’t it about time your home entertainment entered a new dimension, too? The ASUS G51J 3D is the first NVIDIA® 3D Vision laptop to offer a full-resolution 3D display, and movies, games and photographs all burst from its screen with astonishing clarity. It’s all thanks to innovative new 3D technology that provides a fully immersive experience with eye-popping detail, giving a whole new meaning to the term ‘3D gaming’…

The illusion of depth
The ASUS G51J 3D combines a quad-core Intel® Core™ i7 processor with incredible NVIDIA® GTX 260M graphics for unbelievable 3D gaming performance.”
3D — or ‘stereoscopic’ — images have been around since the earliest days of photography, and the principles behind modern 3D displays are the same as those used 150 years ago. All stereoscopic displays create an illusion of depth in a two dimensional image by mimicking the way in which our eyesight works — by superimposing two photos of the same scene taken at slightly different angles. How successful the resulting 3D image is depends on how those two images are then separated.
Crystal-clear 3D images
Rather than degrade a superimposed image by using such primitive stereoscopic techniques as red and cyan-coloured tints, or polarised screen filters, NVIDIA® 3D Vision displays each pair of images alternately, in rapid succession. When viewed through glasses with LCD lenses that ‘blink’ in time with the display, the result is a crystal-clear, full-resolution 3D image that can be viewed from any angle.
NVIDIA® 3D Vision supports over 400 games, so where better to enjoy the benefits of this groundbreaking technology than in a cutting-edge gaming laptop? The ASUS G51J 3D combines a quad-core Intel® Core™ i7 processor with incredible NVIDIA® GTX 260M graphics for unbelievable 3D gaming performance. So, with the ASUS G51J 3D, you can sit back, slip on the special 3D glasses and experience a stunning new visual sensation that will bring your gaming to life.
LIFE IN 3D
Humans see in stereo because our eyes are spaced slightly apart, and so each sees images from a different angle. The two images are combined by the brain to give a perfect 3D image. Although 3D displays rely on the same two-image principle, the images are combined in different ways.
Good
Simple 3D displays superimpose two differently coloured images, which are viewed using glasses with one red and one cyan lens. The image can be blurry, with poor colour separation.
Better
Some 3D computer screens display an interlaced image behind a polarising filter. Glasses with polarising lenses then split the single image into the two originals, one for each eye. This creates a convincing 3D image, but interlacing means that the resolution is half that of the original image and the 3D effect disappears if the screen is viewed at an angle.
Best
The ASUS G51J 3D displays each image alternately, in rapid succession on a custom 120Hz screen. Glasses with LCD lenses that ‘blink’ in time with the display mean that each eye only ever sees one of the stereoscopic images. The result is a full-resolution 3D display with high frame-rates that can be viewed from any angle.
