Hot on the heals of their acclaimed W4000 series of LCD TV's, Sony have announced an upgrade in the shape of the W4500 along with the introduction of the X4500 range.

Specs on Sony's top end X4500 look very exciting, combining the latest Bravia Engine 2 Pro (W4500 retains Bravia Engine 2) along with DRC 3.0 (Digital Reality Creation) which employs up-scaling technology to boost the number of pixels from Standard Definition sources. Bravia Engine 2 Pro uses advanced filter technology to 'clean' incoming pictures before they hit the screen.

New 'backlighting' technology can instantly reduce or enhance picture brightness, compensating for prevailing on-screen or ambient light conditions, reducing light leakage for high contrasts.

Both the W4500 and X4500 series features Motionflow PRO 100Hz technology which inserts additional frames to boost the fps (frames per second) from the usual 50 to 100 and create a judder free picture for fast on-screen action. The Sony X4500 also features IB Reduction/blacklight blinking which intermittently switches off horizontal backlight portions of the frame for what Sony claim even smoother transition of frames.

All the new panels feature Sony's award winning XrossMediaBar (XMB) user interface and have the ability to stream music and photos using the DLNA (Digital Living Network Alliance) standard.

The W4500 line-up includes 40in, 46in and 50in models while the X4500 series feature 40in, 46in and 55in screens. no prices or estimated time of arrival for the UK as yet.
