Welcome to our website! As we have the ability to list over one million items on our website (our selection changes all of the time), it is not feasible for a company our size to record and playback the descriptions on every item on our website. However, if you are an American with a disability we are here to help you. Please call our disability services phone line at (810) 984-5509 during regular business hours and one of our kind and friendly personal shoppers will help you navigate through our website, help conduct advanced searches, help you choose the item you are looking for with the specifications you are seeking, read you the specifications of any item and consult with you about the products themselves. There is no charge for the help of this personal shopper for any American with a disability. Finally, your personal shopper will explain our Privacy Policy and Terms of Service, and help you place an order if you so desire.

The Most Detailed Color Grading

UHD 4K resolution presents breathtaking clarity and fine detail with four times the resolution of Full HD. With this feature, users can experience immersive viewing. Plus, it is color calibration to help maintain accurate color on the screen.

New Level of Color Performance

Nano IPS display delicately expresses richer colors at any angle.

Color Range with DCI-P3 98%

The monitor supports a wide color spectrum, 98% of DCI-P3* color gamut and 135% of sRGB, which is ideal for image re-touching and accurately expressing the color of digital contents.

Delicate Color Expression

Nanometer-sized particles on the screen's LED absorb excess light wavelengths, realizing richer color expression that accurately reproduces all content, from actual images and videos to CG.

Clearer and Brighter HDR

The monitor supports VESA DisplayHDR 600 with wide-range brightness and contrast, enabling dramatic visual immersion in the latest HDR games, movies and images.

The Most Productive Workstation

It is possible to establish a dual-monitor environment by connecting two 4K monitors and a laptop using a Thunderbolt 3 cable. Now it is able to charge the laptop and fast data transfer through the same cable.

4K Daisy Chain

The 4K daisy chain* function enables simultaneous processing of high-capacity videos and images on a portable device while using a latest MacBook Pro, without the need for multiple cables.

Faster Speeds

Transferring data at speeds of up to 40GB/s-two times faster than Thunderbolt 2 and eight times faster than USB 3-Thunderbolt 3** delivers the fastest connection to any dock, display, or device.

Easier User Interface

OnScreen Control gives quick, easy access to a host important monitor settings.

Increasing Work Efficiency

With its elegant, stunning profile, this monitor turns heads even when powered off, with its new virtually borderless design and gorgeous new Edge-ArcLine stand addition to its refined image.

Extended warranties are usually very inexpensive and can save you thousands in the future. It's simple and inexpensive to purchase extended warranties and one of the smartest ways to protect your investment.

Electronics can be large, heavy and expensive. You probably don't have the special tools or expertise needed to fix them in a crisis. If you can spare a few thousand dollars without batting an eyelash for new electronics should they break tomorrow, don't buy a warranty. But if you're like most of us, protect yourself by purchasing inexpensive extended warranties when you buy a new product and save yourself big money in the long run.
