My question is how do i change the contrast,brignest and those things on Dell Inspiron 1501 cuz normal monitor on pc have the bottons for that but what about this?
There should be a key on there with blue letters that say FN for function and then the arrow keys will have blue buttons for it to or if they don't have a look around your keyboard tell you find it.
Look at your arrow up and down keys and you should see, in blue, brightness up and down. And to use those buttons all you have to do is press the blue Fn button, which between the Ctrl button and the Windows button.
