Harman/Kardon is responsible for the audio, and as it managed to make a humble netbook like the Toshiba NB550 sound great, it's no surprise that the F750 holds up well here, although (keeping in mind that it was hard to tell outside of a proper testing environment) we did feel bass was underdeveloped.
Last but certainly not least, in 2D the 15.6in, 1,920 x 1,080 screen showed itself to good advantage in our limited time with it. As it's a 120Hz panel, motion was very smooth. Contrast seemed reasonable and viewing angles were surprisingly good. But of course, the real area of interest here is 3D – how does the F750 fare in its world-exclusive glasses-less glory?
There's no question that glasses-free 3D works. Once the webcam had latched onto our eyes, we definitely saw the extra dimension. This Qosmio offers some advanced 2D-3D conversion processing that worked well, and it's all without looking like a total nerd, pressing any on buttons, or darkening your environment. Also, fluorescent lights had no discernible negative impact. The sheer amount of technology at play here is undeniably impressive, and it's pretty cool to see 2D and 3D side-by-side on the same screen without any eyewear.
However, it's far from perfect. For example, when changing position, the webcam kept up remarkably well (a separate window showed us the wireframe tracking, a bit a la Kinect) but the lenticular layer adjustment lagged slightly and was painfully obvious when it did happen. During general viewing, sharpness was compromised, and we saw a pixel-like effect similar to that of watching a projector screen from so close you can see the cloth texture. The dreaded crosstalk also put in a strong appearance, far more than with glasses-using alternatives like the HP Envy 17 3D.
We'll withhold final judgement until we've had a proper play in our lab but, based on our brief impressions, we would happily put up with the discomfort of 3D glasses for the benefits they bring over this specific incarnation of Toshiba's glasses-free 3D. However, if you want to get in on the lenticular action or just really hate wearing 3D glasses, the Qosmio F750 should be available at the end of August for around £1,300.
