How to read this comparison
Manufacturer facts for the exact models shown. Not a quality rating or a test result.
“Different” means the known values differ, not that one is better.
Missing or conflicting evidence is marked and never counts as a difference. Source chips hold each fact’s sources and conditions.

ViewSonic VP3256-4KIPS Technology
Manufacturer specification · Manufacturer Display · Panel Type: IPS Technology. Original measurement and configuration scope retained.
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.
Manufacturer specification · Manufacturer Display · Refresh Rate (Hz): 60. Exact connection/mode wording. No refresh at a different resolution, overclock mode or input-frequency range is silently combined with the native grid.
Check the exact input, signal mode, source and cable. A connector version or supported timing does not guarantee every console mode, VRR setting or game frame rate.

What it brings
The manufacturer publishes exact-model screen, connector and stand specifications. Use the actual diagonal and full input/mode conditions to match the display to your desk and source device.
Manufacturer brightness, response and colour claims are not independent measurements or a picture-quality verdict. USB-C, HDR and variable-refresh wording must be read with the listed direction, signal and mode restrictions; unknown support stays unknown.
USB-C carries video, data and 90 W, with MST daisy-chain output (not from Macs, which BenQ says daisy-chain only via Thunderbolt) and a 10 Gbps USB hub.
