Having an iScan HD+ is a dream but utilising it to its full potential is a jouney. I rely on the operator manual for a lot of adjustments but honestly I find that it should have more information on it to help the users out. To people in DVDO and experts, I need to find out: 1. H-Sync How to use this setting and what effects it will do to my plasma apart from what the name says. Can someone explain the the units its in? Is it Hz or percentage of your plasma horizontal frame rate? 2. V-Sync Same as above. 3. By changing the H-Sync/V-Sync settings on the HD+, will it be sending out a new H and V sync rates to the plasma (I have a 42PHD7). 4. H-Size and V-Size The native resolution of my 42PHD7 is 1024 by 768. I am using a user-defined resolution at 1050 by 786P. Reason being that the native resolution does clip some of the SKY + moives or programmes (UK's satellite provider) I am viewing to a smaller video area. Somehow the HD+ does not lock the video area to what my plasma will display. Question is am I doing the right thing here? Will it harm my plasma? Is there a better or right way for this? Would appreciate experts in DVDO or the forum to shed some light on this.
