Duplicate screen works, but when switching to HDMI no signal


Jul 16, 2013

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.
