In some implementations, a computing device may include a first display device and a second display device. An embedded controller may determine a first amount of ambient light and a first current associated with the first display device and modify the first current to create a first modified amount of current associated with the first display device. The embedded controller may determine a second amount of ambient light and second current associated with the second display device. The embedded controller may determine a ratio of a first perceived brightness of the first display device to a second perceived brightness of the second display device and modify the second current until the ratio is within a predetermined amount from a target ratio.
