Product Highlights

Sunlight readable 3,500 nits brightness, Fanless thermal management, Integrated Android™ media player, Blackening defect-free in direct sunlight, Narrow 8.5 mm bezel for video wall applications, 1080p Full HD resolution.

TrueColor™ Calibrated

Each screen is individually color calibrated to the D65 (6500K) CIE color standard. Not only does this produce a true, natural white, but also accurately reproduces brand colors, skin tones, and colorways.

Blackening Defect Free

Most residential and commercial screens will blacken or result in isotropic failure when the LCD panel overheats. The DS491LT4 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.

Built-In Media Player

An integrated Android™ based media player with WiFi offers users the freedom to select from the array of various media software solutions on the market or use the bundled DynaScan DSM365 application for local video playback, playlist creation, and content scheduling.

Narrow Bezel for Video Walls

The DS491LT4 features an 8.5 mm narrow 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.
