What matters

Both monitors provide a 27-inch 5120 x 2880 IPS workspace at 60Hz and about 218 pixels per inch, factory-calibrated color with Delta E of 2 or less, USB peripheral hubs, and KVM support. The BenQ premium does not buy more resolution; it buys a different docking, control, contrast, and calibration system.

Key differences

  • The ASUS claims 99% DCI-P3, 100% sRGB, and 95% Adobe RGB coverage, with DisplayHDR 500, USB-C DisplayPort, 96W power delivery, a USB hub, and Auto KVM. It covers a single-display creator desk without requiring a Thunderbolt workflow.
  • The BenQ claims 98% P3 plus 100% sRGB and Rec.709 coverage, 2,000:1 contrast, HDR400, Thunderbolt 4 input with 90W power delivery, Thunderbolt 4 output with 15W, daisy chaining, KVM, a Hotkey Puck G3, and AQCOLOR Pilot calibration software. Those additions matter when they replace separate docking and repeated display-control work.
  • ASUS Auto KVM requires one host over USB-C DisplayPort and the other over HDMI or DisplayPort plus USB upstream. BenQ chaining and calibration depend on supported host ports, operating system, cables, topology, and software, so map the complete signal path before paying for either workflow.
  • In the current US same-market source check, ASUS listed the PA27JCV at USD 699 and BenQ listed the PD2730S at USD 1,499.99, a USD 800.99 gap. The difference can fund a calibrator, monitor arm, storage, backup, or a second display, which means BenQ needs measurable daily payback rather than a generic premium reputation.

Who it is for

  • Buy the ASUS for a lower-cost 5K desk that needs 96W USB-C power, a peripheral hub, KVM switching, and broad creator-gamut coverage without Thunderbolt chaining.
  • Buy the BenQ when a supported Thunderbolt 4 chain, 2,000:1 contrast claim, Hotkey Puck, and the calibration workflow are used often enough to repay USD 800.99.

Watch-outs

  • Test the exact computer, operating system, GPU, ports, cables, scaling mode, KVM wiring, downstream displays, and calibration software. Manufacturer gamut figures are not cross-lab measurements, and HDR certification does not make either monitor a mastering reference.
  • Buy neither if the host cannot drive 5K at the intended scaling, the desk cannot accommodate the display and accessories, or the existing monitor already meets color and workspace needs. Include cables, an arm, a calibrator, adapters, warranty, tax, and promotions in the final total.
