Some newer model DVI monitors work with digital cable tuners because the monitors are High-Bandwidth Digital Copy Protection (HDCP) compliant. Using a DVI monitor to watch TV without a computer also requires an HDMI-to-DVI adaptor. Any monitor will display a television signal connected to a computer TV tuner card. The encoding software that converts analogue information to digital creates a small latency or delay when you watch TV on your computer, but you will be able to record what you watch.

Things you need
- TV tuner card
- Phillips-head screwdriver
- HDCP-compliant monitor with at least 720p resolution
- HDMI-to-DVI adaptor
Unplug your computer and remove the side panel from the case. Ground yourself by touching a piece of metal on the case. Press the TV tuner card into a PCI slot on your motherboard and secure it to the case with a small Phillips-head screw. Close your computer case and plug in your computer.
Turn on your computer and put the tuner card's install CD in the drive. Follow the instructions for installation and restart your computer to finish installing the software.
Connect the coaxial television cable to the input on your tuner card. Run the TV tuner software and answer the questions it asks about your location and type of connection. Wait for the software to scan for your channels.
Use the remote control to change channels, adjust volume, scan forward and backward and record programs. Attach the infrared sensor to the tuner card and position it in range of the remote. Your card's infrared sensor may be built into the device if you have an external TV tuner that connects to your computer via USB or FireWire.
Set the screen resolution of your set-top box to 720p or to the resolution of your monitor. Disconnect the set-top box from the television.
Attach the HDMI-to-DVI adaptor to the DVI input of your monitor. Connect the HDMI output of your set-top box to the adaptor, plug in the monitor and turn it on.
Use separate speakers for sound, unless your monitor has composite inputs for audio. Connect your set-top box to a home stereo system or to your monitor with left- and right-channel RCA cables. Computer speakers will work if your monitor has a 1/8-inch output port, but you will still need to connect the set-top box audio to the monitor with RCA cables.
Tips and warnings
- Using a TV tuner card with a computer offers more compatibility than connecting a monitor directly to a set-top box. Most monitors will not work directly with set-top boxes. Make sure your monitor meets the requirements before disconnecting your television.
