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.

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 BL2490C

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 source

What to check

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.
