Question

Today when Dylan turned on his computer, he noticed that the monitor was very dim. He could still see the desktop icon and text. He turned the brightness all the way up, but that did not correct the issue. Dylan also checked to make sure the Power Options brightness was not turned down, causing the screen to go dim. He connected a different monitor, and the screen was fine. What caused the screen to be very dim
