|
|
hay guys, we have 2 moome internal hdmi cards installed in 2 different 9500lc's we are getting ringing (edging) on the moome cards, dosent matter on sources ( dvdo and ken's sencore generator ) swapped one of the cards out with the older dvi moome card and the ringing goes away, same cables etc. tried different polalritys h+ h+, h+ h-, h- h+, h- h-. all the same h+ h+ looks a tad better in some respects to the pic so that is what i left it.
both hdmi cards are doing it. the moome dvi is not. 2 other peoples cards are not either.
oh ya, 1080p 60hz.

Arli, somebody posted in the external box thread that removing the gamma circuit fixes it.

for our guess, the issue might be new chip on the gamma card,
the new opamp has better performance than previous one,
so we decide upgrade it, and we have test with no problem at our side.
we will check this issue with more testing, and give a solution later!
can you let me know your connection?
for example:
DVD==>hdmi cable==>ext box with VGA output==>VGA to BNC cable long 1M==>PG 6000 projector!
thanks
