When I turned on my computer today, the desktop loaded up with part of the screen off the edge of the monitor. When I adjusted the screen into the right place I discovered the part that had been off screen was actually completely black. It still functions, all the buttons and the cursor beneath it still work. It just shows nothing visually. Whilst it does not affect the usage of my computer, it is extremely irritating, so if anyone knows of a way to return that part of the screen, I would be much obliged. Whilst I cannot upload a direct image, as the screen is still there in print screen, I have attached an approximation of what I see.
