Brand new monitor

I can use it as a DVD player, but sometimes it doesn't happen for hours otherwise I could try and see if its just on the PC channel. I also have a HDMI connector I could try? But like I said sometimes doesn't happen for hours.

No, it doesn't do it doing any of them

That was my original thought, because my monitor "auto adjusts" when resolution is changed so unless its AMD CCC or something else adjusting my res, but it does so it when PC is idle.

Hi,

It might be the 1) TMM service, take a look at: Disable 'Monitor Off' detection, how?

or 2) A buggy GPU driver, try to use an older one.
Hope this helps,

Regards,

Drivers fine because it's not always been like it.

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!
