Hi brink, no i am using a desktop, the only way for me to adjust brightness is through the monitor option. And the Gamma option in the "calibrate colour" option under the Display option in the control panel. No brightness control, i try to lower the Gamma all the way down but not sure if it is a good idea.
Yep, for a desktop you'll have to adjust it on the monitor itself. There should be an actual "Brightness" option on the monitor that you can adjust instead of just "Gamma".
I would recommend to reset the monitor's display settings back to default, and only make small changes at a time to see if you like the change better or not. Some monitors will have preset mode options that you can select that will automatically adjust the monitor's settings for what's best in that mode.
The link below can give you more details about gamma.
