Tried connecting F520 to a different computer with Windows 7 and GPU with analog port and it is still reported as 220MHz...but - I can actually go upto 400MHz resolutions there - it just works. So I was thinking perhaps the Sunix adapter reads 220MHz from EDID and hard-forces this limit somewhere instead of just "letting it through" like Windows 7 just did in my test.
I have been manually playing with EDID in Windows registry as well (to get at least a little familiar with it), changing the relevant byte for pixel clock, but something just overwrote it back when I restarted video or PC. So I removed permissions from everyone to prevent any modifications of this entry and it just resulted in some BAD_EDID error shown as the registry entry name and no cigar.
I wrote to Sunix about this, perhaps I can get a reply from them
What are your EDID reported pixel clocks by the way? I dont remember what it was with my FW900.
