75” 4500 nits 4K UHD High Brightness Digital Signage Display Features: Sunlight viewable 4500 nits brightness, blackening defect-free in direct sunlight, LED backlight with local dimming, ultra HD 4K resolution, and intelligent thermal management system. 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. 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. With Ultra HD 4K resolution, the DS752LT5 produces a super sharp image for easy-to-read text and incredible detail. The DS752LT5 utilizes a direct 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. 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. This is accomplished with ultra-quiet fans.
