Chock Full of Projector Patterns

PG-VGA_PC[1] There’s nothing like a digital pattern generator for making sure a projector is properly tweaked and running a peak efficiency. Unlike other devices, Black Box’s VGA Pattern Generator fits in a pocket and can run on its rechargeable battery, making it perfect for going from classroom to classroom to adjust projectors. It’s good for devices that show resolutions from 640 by 480 all the way up to 1,680 by 1,050 with 34 different test patterns. It costs $400, there’s a $500 version for HDMI devices and includes a one-year no-questions asked warranty.
