Computer screens of the future could offer sound as well as vision, eliminating the need for separate loud speakers.



A British company called NXT has found a way to turn a computer display into a speaker, without interfering with the quality of the picture.



Its SoundVu technology has already been built into two models by Japanese electronics giant NEC.



NXT says it also could be used for other products like flat-screen televisions and is talking to several electronics manufacturers about the technology.
