Sony will next month extend its line of dual-role displays - they operate as a TV and as a computer monitor - with a 20in widescreen HD model capable of being wall-mounted and has a 3D sound capability.

The MFM-HT205 sports a 16:9 ratio 1680 x 1050 resolution LCD equipped with Sony's ErgoBright image processing system and the company's Xbrite coating. The display has a 6ms response time, a contrast ratio of 1600:1 and a brightness rating of 470cdpm². Sony claims it has a 170° viewing angle horizontally and vertically. The screen has its own analogue TV tuner.

The screen incorporates two 3W stereo speakers and a 5W sub-woofer - all fed through SDS' 3D WOW audio processing system.

The MFM-HT205 is compatible with PCs and Macs, and has S-video, component, composite, HD-15 and HDCP-compatible DVI ports on board.

The HT205 goes on sale in the US in April for around $900. ®
