Product Highlights

Sunlight viewable 4000 nits brightness, intelligent thermal management, integrated Android™ media player, narrow 8.5/8.7 mm bezel, 1080p Full HD resolution.

Fanless Thermal Management

By eliminating life-shortening fans, the heat generated by the display is radiated away from high-temperature areas while a sensor continuously monitors the internal temperature to protect the system from overheating by utilizing an advanced fanless thermal management system.

Blackening Defect-Free

Most residential and commercial screens will blacken or result in isotropic failure when the LCD panel overheats. The DS491LT5 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 wireless connectivity 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.

TrueColor™ Calibrated

With TrueColor Calibration™, each screen is individually color calibrated to the D65 (6500K) CIE color standard. Not only does this produce a true, natural white, but the color of all screens will also be uniform.
