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

LG 27U421A-B

What it brings

  • The exact manufacturer model links its source specification table and official product gallery.

What to check

  • Manufacturer specifications are claims, not independent measurements, current retailer stock or unstated regional compatibility. Unlisted units and capabilities remain unknown.

Samsung Essential S39GD 27-inch

What it brings

  • The 1920 × 1080 panel supports a listed 100 Hz native-resolution mode. Check the input-specific conditions alongside the figures.
  • The listed 75.0 x 75.0 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 250.7 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.
