I tried to use Windows 7’s “Calibrate Color” procedure (in the control panel’s Display applet) to adjust my display’s settings. The brightness step baffled me.
The step showed a photograph of a man’s upper body. He was wearing a dark suit jacket over a black shirt. The instructions said, “Using the controls on your display, set the brightness higher or lower until you can distinguish the shirt from the suit with the X barely visible.”
Both parts of the instructions are mysterious. I can distinguish the shirt from the suit no matter how I set the brightness, until I set it so low that I can hardly see the image at all. As for the X… I haven’t a clue what it means. Is there supposed to be an ‘X’ printed on the picture? Embroidered on the suit jacket? Formed by shadows in the folds of the shirt? Slashed bloodily on the man’s chin with a switchblade?
I turned the brightness all the way up to 100 which was a little too bright for comfort; no X. It might help if I knew what I was looking for.
