I reviewed your post and I understand that you are facing issues with the display on your computer.
Don’t worry, I assure you I will try my best to get this sorted.
What is the product number of your computer?
What is the make and model of the monitor you are using?
Have you tried the auto image adjustment feature on the monitor?
Meanwhile, I recommend you update the BIOS and the graphics driver from the below link and check whether the issue is resolved.
