The First 3D Gaming Notebook – ASUS G51J 3D
How successful the resulting 3D image is depends on how those two images are then separated – which is where the ASUS G51J 3D has the visual edge.
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. The ASUS G51J 3D combines a quad-core Intel® Core™ i7 processor with incredible NVIDIA® GTX 260M graphics for unbelievable 3D gaming performance.
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.
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.
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. 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.
