Match the monitor to the connection. Refresh limits depend on the input, cable and source device. Confirm the exact regional ports, stand adjustment and mount. Manufacturer response-time methods such as MPRT and GtG are different; neither the image nor these figures establish an independent motion or colour-quality test.

WHAT EACH CHOICE ASKS OF YOU

What it brings and what to check

BenQ RD280UG

What it brings

What to check

  • BenQ lists 7.8 kg without the base (10.1 kg with it) and a 100 × 100 mm VESA pattern, so check a mount’s load rating.
  • HDR is listed as HDR10 and VESA DisplayHDR 400 with a 400-nit HDR peak; its USB-C daisy chain does not work from Macs, which BenQ says daisy-chain only via Thunderbolt.

BenQ BL2791P

What it brings

  • The 1920 × 1080 panel supports a listed 120 Hz native-resolution mode. Check the input-specific conditions alongside the figures.
  • The listed 100x100 mm VESA pattern gives a mounting option when the mount also meets the monitor’s weight and screw requirements.

What to check

  • Response time, HDR support and colour figures are manufacturer claims with different conditions; they do not establish independent motion or image-quality results.
  • Allow for the 181.9 mm listed depth with the supplied stand, plus cable clearance. Check desk depth before choosing this size.
  • The inspected table does not verify height adjustment. Confirm the stand’s adjustment range if fixed screen height would be a problem.
