Sunlight Viewable
Designed for large-scale display applications in bright environments such as outdoor enclosures and storefront windows, the DS861LR4 features a high-brightness LED backlight producing a 3500 nits sunlight-viewable image.
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.
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.
Ultra HD 4K Resolution
With 4K Ultra HD resolution, the DS861LR4 provides a super sharp image for easy-to-read text and incredible detail.
Built-In Media Player
An integrated Android™ 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.
Intel® SDM Ready
An Intel® SDM slot to accept an Intel® Smart Display Module (sold separately). Supporting a variety of modern x64 operating systems, Intel® SDM delivers the same level of intelligence and interoperability as the Open Pluggable Specification, but in a smaller form factor. Compatible with both the Intel® Small (Intel® SDM–S) and Intel® SDM Large (Intel® SDM–L) form factors.
