Why is my MacMini video output to flatscreen tv going dim (about half)

video brightness to tv suddenly is half as bright. Note: on disconnecting and reconnecting video cable (display port to HDMI cable) it goes bright then fades to about half brightness again. I tried a new cable, same results.

这是一个好问题吗?
