The Test Card Generator (TCG) allows you to create a customizable Test pattern to use for testing outputs for a media installation. You can select HD or SD (1920x1080 or 1280x720) which will populate on your card. Then using the input fields you can type in what you'd like the card to say. Provided is a field for a title and labeling the output and input; a Projector using SDI, for example. You can also color the grid lines to further customize and is extremely helpful with multiple outputs. Un-checking the boxes will take away some of the graphic elements to further customize the look of the card. Lastly clicking save will save a PNG titled with the name and selected resolution to your downloads folder.
