<pre>Hi Max,
I apologize for the screw up.
Also, thanks for catching my obvious mistake.
I do not own a monitor capable of 1920 X 1080, and this appears to be causing
problems with other people.
The maximum I have is 1680 X 1050, and I do not have access to it for now.
For IGA1, Horizontal total period is 9 bits, not 8 bits as I mistakenly
considered.
What happens is that pretty much all IGA1 values get shifted to the right by 3
bit positions, hence, a 12 bit wide value is legal.
What happens is that the 3 LSBs (Least Significant Bits) get dropped as a
result of the right 3 bit position shift.
2200 fits within that 12 bits, hence, it is a legal value as far as IGA1 is
concerned.
I will upload the patch shortly, and I will include your name in the commit
message.
