How would one go about changing it? I have an ACER Laptop, but I reformatted with Windows Media Center Edition. Therefore… I can't change it, and it's incredibly hard to see what's on screen, especially when my screen is practically glazed over and mirror-like.
I don't know how you do it on laptops, but regular monitors always have the bottons on the side or bottom that you press for brightness/contrast options.
See if you have a function (fn) button on your laptop. If you do, then you most likely need to hold this button and press another key to change brightness. The keys vary from laptop to laptop so i cant tell you exactly which one to press.
