Duplicate screen works, but when switching to HDMI no signal

[jaydabros]

Guys

I have got Asus Rampage V Extreme and Asus 970Ti and Monitor BenQ and Samsung UHD TV.

I wanted to stream video via HDMI cable however I have serious problem with it.

Video/Audio signal works OK when I send it to my monitor and when I duplicate screens (one on my monitor and one on my Samsung TV).
Both screens are displayed correctly.

However when I am trying to send signal to TV only via HDMI cable it does not work.
It worked previously fine when I was using my old motherboard and the same video card, but for some reason it does not now.

I tried changing PCI-Express settings to be compatible with Gen1, Gen2 and Gen3 but that did not work either.

I am stuck

Please help.

Try changing the order that you turn on and connect the TV and laptop.
For example if you have the TV on the input then boot the laptop or vice versa.
Sometimes it may take 10 seconds for the HDMI handshake to occur.
