WHAT EACH CHOICE ASKS OF YOU

What it brings and what to check

AOC CU34G4CA

What it brings

  • The 3440 × 1440 panel supports a listed 180 Hz native-resolution mode. Check the input-specific conditions alongside the figures.
  • A listed charging output reaches 90 W on the specified USB-C or Thunderbolt port. Match the laptop and cable to that port’s power and display capabilities.

What to check

  • The 90 W charging ceiling may not replace the original charger for a laptop that needs more power. The rating applies only to the stated port.
  • Allow for the 269.4 mm listed depth with the supplied stand, plus cable clearance. Check desk depth before choosing this size.

ASUS TUF Gaming VG34VQL3A

What it brings

  • Two DisplayPort 1.4 inputs, two HDMI 2.0 inputs, picture-in-picture/picture-by-picture and a three-port USB 3.2 Gen 1 hub suit a desk shared between two computers.
  • ASUS lists a 4000:1 typical contrast ratio for the VA panel, 400 cd/m² typical brightness and VESA DisplayHDR 400.
  • The stand provides 130 mm of height travel, tilt and ±10° swivel, with a 100 × 100 mm VESA pattern.

What to check

  • HDMI inputs are listed at 48–100 Hz, so 180 Hz requires DisplayPort; there is no USB-C input.
  • The certificate list names FreeSync Premium Pro but not G-SYNC Compatible, and the user manual says the stand’s ±90° pivot is for packaging only and warns that using it will damage the monitor.
  • At 8.1 kg with stand and 808 × 250 mm footprint (width × depth), it needs a deep, wide desk.
