PC display setting - When using the mirror(duplication) mode, the message is displayed if it is not supported.

Try This

1. PC display setting for dual monitor configuration - Instead of the mirror(duplication) mode, set it to expansion mode.

2. Connect the cable in the product package to both the PC and the monitor one more time.

3. If the same problem persists, then update the PC graphic card driver to the latest version.

If you make a connection with a non standard cable or gender changer apart from the cable in the product package such as RGB to HDMI gender changers,
DVI to HDMI gender changer and so on, the On Screen Control program and the monitor fail to perform normal DDCCI communication, thus it might not be supported.
So, you are recommended to use the cable in the product package such as HDMI, display port and etc provided when purchasing the product.
