You should be looking for the detailed design specifications of DVI and HDMI formats from the relative organizations. For example: http://www.hdmi.org/index.aspx. You will also need to look into the specifications of the video formats, for example, 720p and1080i in order to make judgement to the results. If your results lay within their published specifications, it can be regarded as a valid signal.
VideoMASTER does not implictly contain any caps or limits, as they depend on what signal you are measuring and whether you are measuring for studio quality setup or for the consumers. The margin can be quite different.

Are you able to manually adjust the limits of videoMaster to the precise image you are measuring or does videoMASTER do that automatically, for example does it have a preset imager that you are able to program before hand?
