Even though the same model, no two panels will have identical color appearance. You need to adjust the Red/Green/Blue on one of them to match the other using the OSD (On Screen Display) Menu- Color- Preset Modes- Custom Color. Discussed on page 21 of the SE2416H User's Guide.
Thanks for the reply. I tried to make the settings manually but I never get the same. The difference is large and irreparable. Are there two monitors of this model that transmit the same colors?
Each panel is configured to a baseline at the factories. But no, they will never be the same unless you purchase calibration hardware (colorimeter) and software. Then calibrate them through the colorimeter and software to get the closest match possible.
