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.

Sunlight Viewable

With a brightness of 3,500 nits, the DS491LT4 can easily be viewed in direct sunlight applications such as storefront windows.
