Option "NoPowerConnectorCheck" "True"
Option "TwinView" "True" # enable dual-display support. This is the most important Option;
Option "TwinViewOrientation" "Clone" # dual-display support mode. clone is replication, that is, the two are completely consistent;
Option "UseEdidFreqs" "True"
Option "Metamodes" "1440x900_60, NULL; 1440x900_60, 1024x768" # This line is also important, indicating the resolution of the two devices. The first one before the comma is the local display device, the second device after the comma (,) is an external device. Separate multiple sets of devices with semicolons (;). You can set two sets of solutions or more.
