Product Highlights

Sunlight readable 5500 nits brightness, intelligent thermal management, integrated Android media player, blackening defect-free in direct sunlight, narrow 8.5/8.7 mm bezel for video wall applications, 1080p Full HD resolution.

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 DS491LT6 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.

Full HD Resolution

With a resolution of 1920 x 1080 Full HD, the DS491LT6 provides a super sharp image for easy to read text and incredible detail

Narrow Bezel for Video Walls

The DS491LT6 features a narrow 8.5/8.7 mm bezel display – perfect for video wall applications. With built-in video daisy chaining, a single 1080p source can be used on video walls up to 15×15 in size without the need for any additional external video wall controller.
