UML-273-90 Description

The Bosch UML-273-90 High Performance LED monitor is a 1080p Full HD resolution colour monitor ideal for use with analogue video, digital video recorders (DVRs), and with PC applications. The monitor features a colour LCD flat-screen panel with a 27-inch viewable picture area. The monitor features a wide range of horizontal and vertical viewing angles that provide comfortable, clear viewing – whether you mount it to a wall or to a ceiling.

UML-273-90 Functions

Excellent image quality

The Bosch High Performance HD LED monitors automatically adapt to the input resolution of the incoming video signal, and support up to 1920 x 1080 resolution (Full HD). The monitor’s analogue VGA input easily accommodates the widespread use of PCs in today's security surveillance systems. Their high contrast ratio (3000:1) and a high brightness setting offers excellent colour accuracy and imaging for easier viewing and interpretation of images. The panel refreshes every 12 milliseconds, so you get crisp, clear images with less smearing - and less image “ghosting” in fast-motion video.

UML-273-90 True colour enhancement

The monitors provide true colour performance. The monitors automatically focus on setting the correct colour, temperature, and gamma curve settings to deliver the highest possible picture quality.
