Troubleshooting TV setup
If you encounter problems when trying to connect a TV to the computer, try the following items:
 Certain display adapters need to have TV set as the primary display adapter before it can be
recognized at all. If the computer is not detecting the TV as a display device when the computer
is turned on, set TV as the primary display device in Windows and restart the computer.
 Turn on the TV before turning on the computer.
 TVs require their source setting be changed to the video source that the video card is using.
Select either Input 1, Input 2, or S-video by pressing the Source or Input Source button on the
TV's remote control. This can vary depending on the type of TV you are using. If your TV does
not have this capability, then you will not be able use it as a second monitor without using
special video signal processing (not covered in this document). For more detailed instructions
consult the manual for your TV.
 Set the screen resolution to 800 x 600 (or less).
 Use only one video source. Do not connect two cables to the same TV or monitor.
 For standard analog signals, a TV accepts either a PAL (Europe) or NTSC (North America) signal,
depending on the country it was made for. Make sure that the signal format of the TV matches
the signal output that the card produces (for on-board TV-output, this setting can be changed in
the BIOS).
HP Monitors - What are the Information Files Required for a
Monitor Driver?
Information files for a monitor driver
The word driver for monitors is misleading. It is better to speak of information files. A monitor driver
consists of 2 or 3 of the following files:
 .inf file - is specific to one monitor and can be used with all operating systems. It identifies the
monitor type and supplier information. It also contains information about the monitor
maximum resolution.
 .icm file - controls color matching between the monitor and other devices, such as printers and
scanners.
 .cat file (optional) - is generated by Microsoft and indicates that the .inf has been submitted,
tested and approved by Microsoft for one or several operating systems.
note:
An .inf file can be used without the .cat file.
