👎 Cons

  • The ultrawide 21:9 aspect ratio might not be universally supported by all applications or video content, potentially resulting in black bars.

  • The 100W charging over USB-C might not be sufficient for power-hungry laptops that require higher wattage.
  • The monitor's large size and ultrawide aspect ratio may take up significant desk space.
  • Users without USB-C compatible devices might not fully utilize the "ditch the dock" single-cable connectivity advantage.
