After reading your thread about the low FPS and other oddities, I'm shifting my suspicion to the graphics card.
I have a Sapphire HD7750 silent in my HTPC and I'm seeing a core clock of 800 MHz and a memory clock of 1125 MHz (maximum, it downclocks to 300/150 with no load).
There's something not quite right about your GPU clocks and it very well could be influencing monitor blackout problem.
Wish I could be more helpful but for the moment I'm stumped.
Everyone is :/ nobody seems to be able to help... I've contacted the person I bought the custom built PC off they said to uninstall amd drivers to see if it resets mem clock so obviously they know something is wrong, i've also contacted XFX. Only solution I can see is sending it back. May get this instead MSI Radeon R9 270X Gaming 2GB Overclocked AMD PCI Express Graphics Card - R9 270X GAMING 2G BF4 - Scan.co.uk
RMA GPU so if the problem still persists then it's a cable or monitor so i'll try different cable and monitor. Thanks for your help!
