Thank you my friend for clarifying the current issues and the context in which they are occurring.
Since these are "Post installations Graphics& Display Problems", the best place to discuss and get the best help from great experts will be in the Post Installations Graphics Forum>

You may have to provide concise presentation of your problems starting from the successful installation to the current issues with images like you have uploaded to support and clarify the text in your post.
List all your hardware [MoBo/CPU/Video Cards/RAM] and major peripherals like your Multiple Monitors including
their "Makes and Models" to get fast and comprehensive help.
Good luck.
