External screen "no signal"

[gaborh024]

Dear Community!

I've just purchased a new TV and connected to my MacBook Pro using MiniDP/Thunderbolt to HDMI adapter + HDMI cable. I've tried with two different cables but the computer can't give signal to the TV after sleep or reboot. Its working after proper shutdown and power on the computer but I'd like to use my computer with Sleep option as before when I stop using it instead of power down every time.

This is what I'm using:

I realize this doesn't "fix" the problem.
But try it anyway.

When the tv won't come alive (after sleep), disconnect and then REconnect the HDMI cable to the end of the displayport adapter.
Just a quick "break, make".

See if that nudges the Mac to start sending a signal to the display again.

Thanks, I've tried it with another variations too - disconnect from machines (tv and computer) too but didn't helped.
