The external monitor flickers when connected to my L440 and ThinkPad Basic Dock but does not when connected to a different laptop using the same VGA cable.
How can I fix this?
The ThinkPad Basic Dock may contribute to a a black screen or flicker on an external monitor connected by VGA when a ThinkPad L440 and L540 laptops running Windows 7, 8, and 8.1 is docked.
To resolve these issues, download the latest firmware, 1.43 or higher, for the ThinkPad Basic Dock from the Lenovo eSupport website from the following URL: http://support.lenovo.com/en/documents/pd027983
