Thank you for your response.
I was looking at your computer specifications and it supports VGA and HDMI. I was wondering if you were able to connect external displays before updating the graphics driver?
Also, how are you connecting the external monitor?
I recommend you to use a straight-through connection with a single cable. Try using other cables and make sure you are not using any adapters.
In addition, to discard a defective port, you can test other devices in the other ports available in your computer.
My monitor was connected with a VGA cable. I replaced it with a HDMI cable and it is much better. I think there is still a difference with my spouse screen, but now it is acceptable. The shadow is gone.
Regarding the update of the driver: I think that the update has not been successfull. I think I still have a old version. Should I try again? Which version should I choice? I tried the win64_15.3346.4885 one. But when I look which one is installed, I have the 10.18.10.4252 version dated July 2015. So that why I think the update has not been successful.
Thanks a lot for your help.
I am glad to hear that the video quality of your monitor improved.
