The most important thing you can do to get a good picture on your Game Boy Advance display is to play in good lighting. Good lighting illuminates the screen evenly. It is bright enough that you can see everything clearly. Good lighting has no glare. Good lighting also allows you more freedom of movement. If you find that you have to hold your screen only at one angle, and that other angles provide an improper image, you need to adjust your lighting. The best lighting is indirect, that is, the light does not shine directly from a light source onto your screen, but rather bounces off a surface, such as a white wall, before it hits the Game Boy's display.
Purchase an antiglare decal for your Game Boy Advance display. Stick the translucent decal onto the screen, following the included instructions. This will help to prevent screen glare. This would be helpful in situations in which there is a bright source of light that would tend to reflect off the screen into your eyes, obscuring your view of the display.
Since a Game Boy Advance display is small, you might have trouble seeing the image properly. Magnifying eyeglasses are one solution, but if you want an option that will always be part of your Game Boy unit, one display idea is a screen magnifier. A screen magnifier is an add-on which you mount over the screen. The built-in magnifying glass will make the display easier to see, and any on-screen text will be easier to read. You can get screen magnifiers from online retailers or from a local game store.
