|The issue you are experiencing probably is due to an improper resolution. LCD-TVs use 16:9 ratio, while computer LCDs use 16:10. This can result in a sawtooth pixel line. |
Solution is to be sure to use the recommended resolution for the TV. If that resolution is not available then update your graphic drivers.
How are you connecting the TV to the computer?
If you have an HDMI port on both ends then use that.
