I would like ask for Radeon 6670.
I need to connect ho UHD TV Samsung 7002 from Graphic Card HDMI port.
When I connect cable, PC has recognized him - in Screen resolution Detect - Samsung - multiple monitors it seems ok.
TV has also recognized input cable, but no input signal. When I connect same cable to Notebook- all is ok - so cable ist good.
I have Win7 64 bit . In AMD catalist centre for settings My Digital Flat panels: maximum resolution 1920 x 1080(UHD is not working for 6670 of course), refresh rate 75 Hz , maintain aspect ratio.
Maybe I need add any HDTV mode?
