I have an alienware 17 that i want to use as a monitor to play ps4 games on. However, when i do, the screen is really dim. Even when i use keyboard shortcuts to up the screen brightness to maximum, it is only like 30-40% of the max brightness as when i use my computer normally. Is there a way to access or change the settings or brightness of my laptop's screen for hdmi in? For reference, i have windows 7.
