Mini-Byte: Troubleshooting your PC to TV Connection
Posted by tekkieteacher on March 4, 2008
As we go through the school and connect the classroom PCs to the TVs, there is a question that keeps coming up. It seems that for some TVs the TV has to be turned on first, before the computer, for the PC to TV connection to work.
So, the solution is this — if you are trying to display your computer on your TV and it is not working, reboot your computer with the TV on. That should restore the connection.
Another issue is that some of the older TVs will only work if the desktop resolution is set to be 640×420, which is very large–the icons on the desktop will be huge. You can either keep it at that setting, or you can choose to switch to the larger setting only when you want to use the PC to TV connection. To switch back and forth, I recommend using the video card interface. Here are the steps:
- Right-click anywhere on your desktop and select Properties
- Go to the Settings tab
- Click Advanced button
- Click Catalyst Control Center tab
- Click Catalyst Control Center button
- Click Displays Manager
- Under the Desktop area drop down - select the desktop resolution you prefer
- Click Apply
