Hi all

I have the above desktop connected to a Yamaha RX3060 receiver, and finally to a Sony 4K TV, all connected via HDMI. The graphics card is a intel HD 530( latest version) My only choice at 4K resolution is 30Hz when using HDMI

Both the TV and receiver will output 4k@60Hz.

Do I need to buy a DisplayPort to HDMI adapter to get buttery smooth 60Hz?

Cheers

Darren

Looks like a DisplayPort will solve your problem - According to the specs, the HD530 will only do 4K at 24Hz over HDMI, but 60Hz over DP.

I don't know if DP will carry the audio signal however?

also likely your hdmi is 1.4 and not 2.0 and as someone said, may not decode (ie stutter +++++)

yes, it also seems that I'm limited by the refresh rate of the AMD/Intel chipset as well........still, for most watching/listening it seems ok......would have been kinda good to have all the electronica doing 4k@60 Hz though ;)

Sorry to say, but this will not play back HEVC / H.265 content at 4K nor will it support HDCP2.2 copy protection.

You will be best leaving this device at 1080P, where it will work fantastically
