  Enjoy any content in stunning accuracy. With HDR10 that displays over 1 billion colors compared to 16.7 million for typical SDR technology, dark colors are darker and the brightest are even brighter.
• Every piece of content becomes a joy to look at and can be experienced exactly as the creator intended.
• AMD FreeSync
  AMD Radeon FreeSync keeps the refresh rate of your monitor and graphics card in sync to reduce image tearing for a superfluid entertainment experience. Watch movies and play games without interruptions. Even fast scenes look seamless and smooth.
• Picture by Picture/Picture in Picture
  Multiply the ways you work, chat and play. With PBP, view input from two simultaneous sources at native resolution, allowing you to review two projects or run two programs.
• Use PIP to resize a second source, allowing you to work on one task while monitoring another.
• Borderless Design
  Minimal bezel brings maximum concentration. The virtually bezel-less screen shows you the full picture and looks almost gapless when used in a dual-monitor setup so you can see more at once with no distractions.
• TUV-certified Intelligent Eye Care
  Keep your eyes comfortable. An ambient light sensor on the monitor detects lighting in your workspace and automatically adjusts brightness. Eye Saver Mode minimizes excessive blue light, and Flicker Free relieves eye strain.
