Hi, I have a 2009 Mac Mini with an Intel 2.53 GHz Core 2 Duo processor with an Apple 20" Cinema Display(clear plastic ADC model). I'm using the Apple ADC to DVI adapter with the power block.
The Cinema Display is 12 years old and recently the top portion of the screen is slightly darker than the lower portion. It's a gradual change. Also the power button on the display occasionally blinks. I first noticed that when the brightness(in the System Preferences) is lowered, below the maximum, there is a slight hi pitched noise. When I raised the brightness all the way up the noise went away.
Does anyone know if it could be a problem with the display or could it be a weak signal from either the graphics card in the Mini or the Apple ADC to DVI adapter(w/ power block)?
