Whereas the Acer 5738G uses polarising glasses and a screen filter (which compromises image quality), the G51J uses a more advanced solution: battery-powered LCD shutter glasses. These rapidly open and close each lens to expose each eye to a slightly different image coming from the laptop's 15-inch, 120Hz display. Viewing the same scene from two alternating perspectives tricks your brain into thinking that what you're seeing is a single, three-dimensional scene.
The 3D effect is considerably more impressive than that achieved by the Acer solution. Asus' bundled 3D video demos look very convincing and games such as Avatar look even better. Objects flying towards the screen really do cause you to jerk backwards (or duck), but better still, objects that simply cross each others' paths (cars, people, giant plug-in pterodactyls) are layered so convincingly, you really will believe that some objects are closer to you than others.
The G51J itself is well kitted-out. Its 15.6-inch display has a relatively limited 1,366x768-pixel resolution, but it uses a high-speed Intel Core i7-720 CPU, 4GB of RAM, an Nvidia GeForce GTX 260M graphics chip with 1GB of video memory, a 4x Blu-ray reader and twin 500GB hard drives. All in all, it's unlikely to worry anyone working for Alienware, but it's a capable gaming and multimedia machine nonetheless.
