Hands on with Toshiba's glasses free 3D laptop
Toshiba has just launched its first glasses free 3D laptop, the Qosmio F750 3D. It's a 15.6 inch screen machine which uses a lenticular lens system to divide up the vertical pixel columns, not unlike the Nintendo 3DS. Basically, two images are displayed on screen at the same time, divided between alternating columns, and tiny lenses angle left eye images in the direction of the left eye and right to the right.
I had a play around with the F750 at Toshiba's launch event yesterday, and have to admit it's impressive. We were told that the drivers didn't yet support 3D games on the pre-production models shown off, but watching a 3D video back worked pretty well. When you move your head there's a strange shimmer as the lenses readjust, but it's no more distracting than artefacts when you're watch glasses-unfree 3D.
What's really interesting is that the lenticular system is slid into place on a per-pixel basis. What this means is that you can be using a 2D application on one half of the screen, while a 3D movie is running in the bottom corner. Very clever.
With a measly GeForce GTX 540M graphics card, however, it's unlikely to be able to run games in 3D at any meaningful frame rates. The lenticular system still requires each frame to be rendered twice, and I'm not holding out much hope that this card is up to that.
