Using a test disc is a great first step at improving a display’s picture. We’ve written a DVE tutorial than can assist with this. However, many still find the process difficult or confusing. Most displays also have hidden parameters not known to the end-user that afford even more control. At Avical, we have the technical know-how and testing equipment necessary to take advantage of this extended menu. So for those wanting maximum performance, a professional Avical calibration is their best option.
