Pros & Cons

Pros
  • 5K 5120 × 2880 resolution reaches 217 ppi for extremely fine text and detail
  • Mini LED backlight with 2304 dimming zones lifts HDR contrast over a normal edge-lit IPS
  • 1250 nits peak brightness gives HDR highlights real punch
  • USB-C with DP Alt Mode and 90W power delivery handles video and laptop charging over one cable
  • 750 nits typical brightness is very high for a desktop monitor
  • 99% DCI-P3 coverage delivers very rich, wide-gamut color
  • 165 Hz maximum refresh is well above ordinary 60 Hz screens
  • Fully adjustable stand covers height, tilt, swivel and portrait pivot
Cons
  • Mini LED zoning can bloom around small bright objects on dark backgrounds
  • HDR10 input support has no DisplayHDR tier, so HDR impact stays limited
  • 5120 × 2880 at 165 Hz demands a high-end GPU
  • No built-in speakers listed
  • Native 1000:1 contrast is IPS-like, so dimming-zone behavior decides black depth
  • No built-in webcam
  • No KVM switch listed
  • No smart-TV platform, Wi-Fi or Bluetooth
