Q. DVI Extender does not seem to work with the DVI output of my graphics card. What’s wrong?
A. DVI Extender is designed to be connected to the DVI-D output of your computer graphics card using a
DVI-D cable. Some older graphics cards only have one DVI port but most have two. Occasionally there
might be a subtle difference between the two DVI ports on a graphics card so if DVI Extender doesn’t
work properly with one port, try the other one. If you choose to use a DVI cable other than the one
supplied, ensure it is a single-link DVI-D cable and preferably no longer than 6 feet or 2 meters. It is also
essential to connect Extender to a USB 2.0 port on your computer. If the lamp next to DVI Extender’s
USB port fails to illuminate, there is not enough power for the unit to operate. Another USB port should
be tried or else an AC to USB adapter can be used to supply power.
Q. Why does my Windows graphics driver sometimes report that an HDMI-to-DVI display connection
has been detected even though I’m not using a HDMI connection? Does it matter?
A. This message is just for your information and there is no problem. Your graphics card has detected that
DVI Extender is using a HDMI function to support both DVI video and computer audio. You may wish to
enable the option “Don’t display this message again” before clicking OK to dismiss the message.
Q. Why can’t I output NTSC or PAL video through DVI Extender?
A. DVI Extender supports interlaced NTSC or PAL video via SDI. If your graphics card only supports
progressive NTSC and PAL video, you will be unable to output standard definition video via DVI
Extender. It is difficult to predict whether a graphics card will support interlaced or progressive standard
definition video as this is dictated by a confusing combination of factors including: version of operating
system, model of graphics card and the version of graphics driver. For example, the update from Mac
OS X 10.5.6 to 10.5.7 replaced the interlaced NTSC and PAL video modes with progressive NTSC and
PAL video modes on some or all models of Macintosh computers. They are no longer able to output
interlaced standard definition video but it is possible that a future update might reinstate these modes.
Please check the specifications of your graphics card.
