Not surprisingly, SuperMac, the distributor, can not answer my questions. Can one (or more) of you?: 1. The box says that the board operates at 640x480 and 1024x768, changeable in software. None of the demo units I have seen has such a software switch. Is there one? 2. What is the Horizontal Scan rate? I may want to use my own monitor. The box says that several scan rates are provided. Is this true? 3. Every demo unit I have seen, using the SuperMac monitor, has an annoying vertical artifact, consisting of purple lines, when a uniform gray background is selected. This is possibly due to EMI, but it is SuperMac's card, SuperMac's monitor, on SuperMac's stand. Is this artifact a product of the monitor, or the board. If it is the board, I don't want one. Thanks.
