Hi Everyone,

Last week I have bought a new 4K TV (Samsung UE40KU6000). I want to connect my PC to this TV, to watch movies on it. My PC has 8GB DDR4 2100Mhz RAM, I5 6500 @ 3,2Ghz, Sapphire R9 280 3GB.

I have already bought a Club 3D DisplayPort™ 1.2 to HDMI™ 2.0 4K60Hz UHD Active Adapter ( http://www.club-3d.com/index.php/products/reader.en/product/displayport-12-to-hdmi-20-uhd-active-adapter.html ) , and a new HDMI 2.0 cable ( http://www.sandberg.it/en-us/product/HDMI-2.0-19M-19M-2m )

My problem is when I am watching movies on TV, I usually duplicate the PC's screen into the TV and the video image sometimes falters. It goes smooth. then it falters for 1 or 2 seconds then it goes smooth again . I know it is not a big deal, however it can be really annoying.

Do you have any ideas what could be the problem?

Thanks in advance!
 
I assume you are using the HDMI output of the Sapphire for your monitor. Try using it for the TV. That will help eliminate the converter as the problem.
Set the TV as an extended or second display. That way you can set the output of the PC to match the native resolution of the TV.
