Monitor and tv blinking

[laohe]

Hello,
After laptop connected to tv, the laptop monitor and tv started blinking at the same time every couple of seconds. Could anyone help me to solve this problem? Thanks a lot.

Check your refresh rate make sure that the out put on that cable/output is the same as your monitor/tv.
