I bought the U-3900 in order to be able to run all the peripheral devices (screens,keyboard, mouse etc) for which ever device (desktop or laptop or ultabook) got plugged into the USB port. Unfortunately I have two old monitors that take DVI or VGA input only, so I bought an adaptor to convert HDMI to VGA. Using the DVI port on the U-3900 works fine on both monitors but when using the HDMI/VGA connection the screen is blank. The computer recognises the display as it is visible on the control panel–>appearance–>display–> ‘screen resolution’ set-up - in actual fact it recognises 3 screens though I only have 2 - but there is no picture. I can’t see anything in the HDMI/VGA connector specification that suggests its passive but could that be the issue? Do I need a better connector or a new monitor to get this to work?
Thanks in anticipation
