Product Highlights

The DS851LR4-1 is an 85-inch display that features 4K UHD resolution with a high brightness LED backlight producing a 3,500 nit sunlight-viewable image. Designed for large-scale display applications in bright environments such as outdoor enclosures and storefront windows, each screen is individually color calibrated to the D65 color standard to ensure uniformity among multiple displays.

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.

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 Ultra HD 4K resolution, the DS851LR4-1 provides a super sharp image for easy-to-read text and incredible detail.

High Brightness LED Backlit with Local Dimming

The display features a local dimming LED backlight 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.

Blackening Defect Free

Most residential and commercial screens will blacken or result in isotropic failure when the LCD panel overheats. The DS851LR4-1 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.
