mainboards built with ATI 9100IGP (RS300 Chipset),
9100ProIGP (RS350 Chipset), and RadeonXpress200 (RS480
/ RS400) are carrying on board TV-Out function,
but the VGA-Out / TV-Out functions are NOT
simultaneous. That is, at any time, only one of
the ouput screen is valid. You may set the power
up default screen output to either CRT (VGA Out
Port) or TV (TV Out Port) in CMOS Setup, provided
that you have the valid display device attached
at the target port.
the following conditions apply when the ATI
Display Driver (for Windows) is loaded :
When both CRT (or LCD)
display monitor and TV monitor (Composite or S-Video)
are attached in the system, the ATI Display
Driver (for Windows) will detect the presence of
the CRT (or LCD) display. Then the output screen
will automatically switch to the CRT (or LCD)
after Windows is running, irrespective of the
power up default display output setting in CMOS.
If the TV monitor is targeted as the only
valid display monitor, please detach the CRT (or
LCD) display monitor from the VGA Out Port, and
leave it empty.
