Main Features

  • 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.
  • IPS - IPS 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 stereo speakers.

Fantastic monitor i have progressed from a 14" with most sizes to 30" inch over so many years to this 43 " it looks fantastic after calibration with my x-rite and was not to far off from the box

Happy Customer

last month

I got this to replace a 32" 4K monitor. That was fantastic quality but at ~150dpi I had to run Windows at 125% in order to see the standard 9-point text, which negated the whole point of having a 4K monitor. This one is 100dpi, the same as most 1600x1200 20" monitors. This monitor is by no means perfect. The screen is matte but still quite reflective, couple with IPS so black bits aren't that black. off the center of the screen white text tends to have coloured edges, particularly very small white-on-black text. No amount of fiddling with Cleartype sorts it out properly. The placement of the signal inputs at the back is terrible if you ever want to plug something new in, and the manual controls down the side at the back are... well, the remote control isn't just for show. But none of that really matters because overall it is fab. The best recommendation for this is that if I broke it tomorrow I'd be down CCL buying another one before supper.
