The problem might be in the Windows output. You need both your VIDEO CARD DRIVER and your WINDOWS MONITOR DRIVER to be set for dual monitors. You seem to have the WINDOWS MONITOR DRIVER set up correctly, probably need to work with the VIDEO CARD DRIVER.
Check your monitors independently to make sure you have the MONITOR DRIVERS installed (meaning check them one at a time). I used to have a problem with my HP w2207 monitor because it required an independent driver from the video card, while my HP f1905 did not.
You may also want to check your resolution, most monitors run on 1280 x 1024 just fine, or the hertz output to them, typically want a 60Hz output.
Anyhow, those two things are what I typically check when something is wrong with my monitors. Those adapters rarely have a problem since they are composed of a simple wiring system, fairly close to the wiring of ethernet cords.
