High Definition Convergence
<< Back to Pioneer Tips
Tip from Louis Carliner:
Here is a very important note concerning converging high definition Pioneer and other
displays. This is inspired by a problem that Bob Jones (Mr. Bob) ran into:
Some of the "spectrum squatting" stations, like Fox broadcasts in 480p. Some
of the HD receivers (like the Zenith) passes such signal on as 480p rather than upconvert
(as does the RCA DTC-100) to 1080i or 540p. As a result, there will be no sync'ing
up to 1080i on the Pioneer. If problem is encountered in which 1080i cannot be brought up
when tuned to a DTV station while in the service mode, try another station! On the Pioneer
31K is the rate for 480p and 33K is the rate for 1080i (or 540p).
In order to converge 1080i on the Pioneer, the PyPbPr form of the signal must be
available. RGB will not sync up the grid pattern. However, once the convergence and
geometry using the PyPbPr form has been done, RGB convergence and geometry (except for
raster phasing) will have been done."
