I'm sending a 1080p test pattern (24bit RGB, vsync, hsync, DE) into a 7511w. When I connect to a real monitor, I can see the pattern.
When I feed it back into a 7611, it doesn't appear to accept it - the output appears to be the stock videomode instead.
What registers on the 7611 can I look at to get an idea why it's not working? Both the 7511w and 7611 were initialized with the recommended script from the EVAL-ADV7611EB1Z_scripts_v3_0.zip download.
On the 7511w, I can read the EDID I placed in the 7611, so at least the DDC connection is working properly.
While I'm testing with landscape (1920x1080) now, the goal is to output to a nonstandard portrait mode (1080x1920). Will the 7511w pass that on? It doesn't match any of the modes it knows about.
