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.
Manufacturer source

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.
Manufacturer source
The listed 100x100 mm VESA pattern gives a mounting option when the mount also meets the monitor’s weight and screw requirements.
Manufacturer source

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.
Manufacturer source
Allow for the 181.9 mm listed depth with the supplied stand, plus cable clearance. Check desk depth before choosing this size.
Manufacturer source
The inspected table does not verify height adjustment. Confirm the stand’s adjustment range if fixed screen height would be a problem.
