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.

Inputs and connections
Check the exact configuration and source conditions for your use.
LG 27MR400-BD-Sub: YES(1ea); D-Sub (Max. Resolution at Hz): 1920 x 1080 at 75Hz; HDMI: YES(2ea); Headphone output: 3-pole (Sound Only)
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.
