I don't see any output from the DVI port on this motherboard. But I think it may be due to the fact that I'm using a DVI-to-VGA converter on a "regular" CRT monitor.
Here is the closest resolution I found so far:

Problem solved. I found this post from this same forum http://forums.nvidia.com/index.php?showtop...47&#entry113547
So I looked my m2npv-mx and measured resistance between ddc lines in dvi connector. Data line has nice pullup and pulldown resistors around 5kohm, but CLK line does have any pullup resistor or it's way too big some megaohms. So I solvered 4.7kohm resistor to the bottom side of mb between ddc clk (pin 6) and +5V.
Now windows detect my PT-AE900 even I have 10m HDMI-HDMI cable and DVI-HDMI adapter.
Have to say that asus electronic engineers should go back to school and think why pullups are used
