TestCard App is a small tool to display pixel perfect test patterns on any connected display and video projector. The default test pattern is a custom-made design that suits your needs to caliber any type of display or video projector. You can use it to check the position, the distortion, the colors, the grays, the contrasts, and the interlacing. You can also display any type of grid in any color with or without distortion circles, display a custom bitmap image, standard SMPTE color bars or a customizable color spectrum. All the different patterns can be exported to an image file at the size you need.
