I will appreciate any feed back
I have an Infocus SP7200. Infocus has done a better job with implementing the Faraoudja video processor than what I have seen done with the same chip in DVD players. Sending it 480i from the DVD player is probably your best bet. To compare choose an extreme close up that has tons of fine detail and see which resolves it better, 480i or 480P.
On the SP7205 leave all sharpeness settings at 0. They are called "Chroma detail" and "Luma Detail". Leave "True Color" on (it can't be turned off when receiving an interlaced signal like 480i, anyways). To set the basic settings on the first page of the "Picture" menu, you need the test patterns on DVE, AVIA, or the Sound and Vision test disk. One of these disks should be considered essential. You have to have one to set these levels properly. There is no single proper setting for analogue sources, because they vary.
Properly setting the Gains and Offsetts in the Advanced Color Menu requires special equipment. This is a large part of the advanced calibration that is done by an ISF calbrator. The good news is that when new the 72XX PJs are pretty accurate out of the box.
As the bulb ages with use its color shifts toward green (as with all PJs that use mercury based lamps). A calibrator uses a colorimeter and test signals to correct this shift.
