Narrow Bezel for Video Walls

The DS552LT4-1 features a 10.9 mm narrow bezel display – perfect for video wall applications. With built-in video daisy chaining, a single video source can be used on video walls up to 15×15 in size without the need for any additional external video wall controller.

LED Backlit with Local Dimming

The display features a local dimming LED back light technique for a remarkably high contrast picture. With direct local dimming, darker areas of an image receive less backlighting than lighter areas, as opposed to edge-lit LED backlights which illuminate an entire screen at all times causing blacks and dark areas to appear washed out.

Color Temperature and Quality

Ensuring the color and brightness of each screen in a tiled matrix matches can be time consuming and requires additional calibration hardware. Each screen is individually color calibrated to the D65 (6500K) CIE color standard. Not only does this produce a true, natural white, the color of all screens will be uniform.

Blackening Defect Free

Most residential and commercial screens will blacken or result in isotropic failure when the LCD panel overheats. The DS552LT4-1 is equipped with a high temperature LCD panel capable of withstanding temperatures up to 110˚C (230°F) without blackening – crucial for direct sunlight applications.

Auto Brightness Control

Different external lighting conditions require different brightness levels. An onboard light sensor measures the ambient light in the area and automatically adjusts the image accordingly.
