Product Highlights

2,500 nits brightness, Direct LED backlight, blackening defect-free in direct sunlight, 1920 x1080 Full HD native resolution, narrow bezel.

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.

Full HD Resolution

With Full HD 1080p resolution, the DS421LT4 produces a super sharp image for easy-to-read text and incredible detail.

LED Backlit with Local Dimming

The display features a local dimming LED backlight technique for a remarkably high contrast picture. With 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.

Intelligent Thermal Management

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.
