PBP (PICTURE-BY-PICTURE)
The PbP (picture-by-picture) function allows for simultaneous display of content from up to four different signal inputs. Divided into four, the screen offers users a workplace equal to four Full HD displays put together without the bezel getting in your view and saving you the hassle with extra cables. It’s perfect for a huge range of applications like stock market data, medical desktop publishing, CAD/CAM drawings, graphic and web design.

4K
UHD resolution (3840x2160), better known as 4K, offers a gigantic viewable area with 4 times more information and work space than a Full HD screen. Due to the high DPI (dots per inch), it displays an incredibly sharp and crisp image.

FLICKER-FREE + BLUE LIGHT
The ultimate solution for the comfort and health of your eyes. Flicker-free monitors with the blue light reducer function substantially reduce the strain and fatigue caused by flickering and blue light emittance of regular monitors.

VA MATRIX
VA panel technology offers higher contrast, darker blacks and much better viewing angles
than standard TN technology. The screen will look good no matter what angle you look at it.

SPEAKERS
This LED monitor is equipped with two high quality stereo speakers.

Warranty

We stand by our products!

All our products are covered by a manufacturer's warranty unless stated otherwise on the listing (usually under the conditions tab). This applies to manufacturing defects or hardware faults that develop in the first months of ownership (between 6 and 12 months depending on the item).

All orders are posted with a VAT invoice in the box showing the date of purchase, price and VAT details. Please keep this invoice safe as it is sometimes required for warranty claims. You are of course welcome to contact us for a replacement invoice if needed, and we can also email copies if you would like a digital version.

Please note: Any item delivered damaged must be reported to us within 48 hours of receipt.

In the event of a fault developing in the first 14 days of receiving your purchase, please get in touch with us as soon as possible, we will help you with troubleshooting and resolving the issue. If a fault develops after 30 days, you will need to get in touch with the manufacturer to open a warranty claim. This will usually involve letting them know what has gone wrong and they will arrange for the issue to be rectified for you. If for any reason the manufacturer rejects the warranty claim, or you have any other difficulties please contact us and we will be more than happy to help.
