contains two types of analog and digital EDID. Digital EDID will set as the default and
analog EDID will automatically change refer to analog signal. This is likely that your
PC read EDID type before making decision to send analog or digital from DVI-I port.
However, this compatibility limitation is rarely found on PC, workstation, or Mac.

Think of USB as a smart plug for PC peripherals. USB automatically determines
resources (like driver software and bus bandwidth) required by peripherals. USB
makes necessary resources available without user intervention. There are three main
benefits of USB. USB eliminates "case anxiety," the fear of removing the computer
case to install circuit board cards -- that often requires adjustment of complicated IRQ
settings -- for add-on peripherals. USB does away with "port gridlock." Without USB,
PCs are normally limited to one printer, two Com port devices (usually a mouse and
modem), one Enhanced Parallel Port add-on (scanner or video camera, for example),
and a joystick. More and more peripherals for multimedia computers come on the
market every day. With USB, up to 127 devices can run simultaneously on one
computer. USB permits "hot plug-in." No need to shut down, plug in, reboot and run
set up to install peripherals. No need to go through the reverse process to unplug a
device. Bottom line: USB transforms today's "Plug-and-Pray" into true Plug-and-Play!

A:
A USB hub provides additional connections to the Universal Serial Bus. A hub's
upstream port connects a hub to the host, usually a PC. Multiple downstream ports in
a hub allows connection to another hub or device, such as a USB keyboard, camera
or printer.
A:
If you experience the problem, just detach and re-attach the USB hub cable
between PC and your monitor, then refresh your PC device manager (Start > Setting
> Control panel > System > Hardware > Device manager > Refresh) or reboot your
PC and the problem can be solved by above procedures.
