AMD vs. Controlling the bright on the screen.

[Elizara]

Okay. A friend of mine (he may join in in a moment, or at least tell me some more information) is having some trouble. I tried to help but we've gotten nowhere.

It seems he has a AMD video card and he cannot adjust the bright on his screen -- the brightness bar is missing. It MIGHT be a bug with the driver, I don't know. We've tried upgrading the driver btw, everything short of playing with the registry. (he can't find the value/file in the registry to fix that either)

Does anyone have any ideas?

Generally brightness is adjusted on the monitor itself. The settings you might see in old driver control panels don't make the screen any brighter (light output), they generally adjust the color/black/white saturations. It's like the brightness settings in games on pc: they raise the darkness floor rather than actual light from the monitor (dark colors stand out more against pure blacks, mostly washing out lighter colors if you put it too "bright"). In windows 10 at least, windows seems to be taking over the task of fine tuning color (at least with amd crimsons drivers). The older drivers can take that ability back from windows but it just does the same thing windows does to colors.

Laptops have screen brightness settings since it helps with battery life and the screens don't have individual controllers like monitors, but that ability does not extend to a plugged in monitor (can't adjust light output).

Are you sure you want 'Brightness' and not 'Gamma'?

The Gamma control is typically what your computer controls to change light levels - confused with brightness.

Is it perhaps a CRT monitor? They tend to dim the older they are, but can be fixed ...I had one about 15 years ago that was so old I had to open it up and adjust it's internal controls for brightness.
