As a last resort you may also test with our latest generic graphics driver from Download Center. This is an alternative driver and can be used only if the customized driver from original equipment manufacturer (OEM) has issues.
Do not use adapters on the video cables. Connection needs to be straight. HDMI to HDMI, VGA to VGA, etc.
Check the laptop form factor. It's possible that the graphics controller allows the multi-display but the laptop does not have more than 1 video output.
Laptops have dedicated support groups that can help any issue that the device can encounter. Contact the device manufacturer for further support.
