A test and alignment system for an electronic display device comprises a test pattern generator to be connected to an electronic display device for causing images of video test patterns to be displayed by the electronic display device. A test fixture is positioned in front of the electronic display device to be tested and aligned. The test fixture includes a frame supporting a plurality of close-up optical sensors to sense and produce image signals corresponding to small areas of images displayed on the electronic display device and a plurality of wide-angle optical sensors behind the close-up optical sensors for sensing and producing image signals corresponding to large areas of images displayed on the electronic display device. A computer controls the test pattern generator and processes and analyses the image signals generated by the close-up and wide-angle optical sensors to perform a series of tests on the electronic display device. A display provides a visual indication of the results of the series of tests performed by the computer.
