With an advanced In-Plane Switching (IPS) panel and full 1920 x 1200 HD resolution, the 25.5" BT-LH2550 LCD production monitor delivers stunning picture quality and greatly expands the range of colours you can view on screen. Designed for applications that require the highest resolution and colour performance, the LH2550 has an exceptionally wide colour gamut -- it surpasses the ITU-R BT.709 standard (130%), enabling it to display a greater range of colours than conventional LCD and CRT displays. The monitors IPS panel technology ensures superior performance with high contrast and brightness (1000:1 contrast ratio), 10-bit processing, wide viewing angles and exquisitely detailed pictures. The LH2550 ensures you have the perfect colour every time for far less than premium-priced reference monitors.

The monitor features a full range of professional level inputs including two auto-switching SDI (HD/SD) inputs (with switched output), component and RGB, and adds a DVI-D input. Additional tools include vectorscope and waveform monitor functions, a split-screen function that simultaneously displays two images side-by-side from two different type video inputs. And built-in calibration software that allows the monitor to be calibrated without using a PC.

The LH2550 incorporates a space-saving design with a slim frame and aluminium alloy back panel; its 1/3 lighter than its predecessor, the BT-LH2600W. It offers noise-free operation (no cooling fan), and is VESA mount compatible.
