Thank you for choosing ScreenRuler. ScreenRuler is a PC software product to allow part of the PC screen to be highlighted. This will assist you with viewing and concentrating on text. It provides a "strip" across the screen, which can be magnified, can have the contrast changed and have the background darkened out if desired.
ScreenRuler will work with any piece of software, as it acts as an "overlay" on the PC screen. From a technical point of view, it should not interfere or clash with your PC video card.
