Philips has been demonstrating one of its new ranges of 3D-ready TVs to goggle-eyed press here in Barcelona. The 8000- and 9000-series will be 3D-capable when they launch in June, although final details of the active-shutter glasses have yet to be settled. The flagship, super-widescreen Cinema 21:9 will become available in a 3D-ready guise in September.So how was it? Well, I got an eyeful of a 46in 9000-series running a number of computer-generated movie trailers with a touch of live action here and there.The temptation with 3D, as with any new trick, is to turn it up to the max, and while extreme 3D effects work in the cinema, on the evidence of this demo it seems a subtle approach might be more successful. The illusion of depth was fairly impressive, but was broken when characters popped out of the screen and were cropped by the frame of the set. In a cinema your field of vision is pretty much filled by the screen, but even with a 46in TV you're still very much aware that you're looking at a picture in a box.Impressive, certainly, and with the glasses I was using there was still a fairly bright picture coming through, although how bright an image you'd get in a room that's not been darkened remains to be seen.It's a promising start, and there may be time between now and the June launch to tweak the performance further still. We'll keep you posted.
