Hi all

Can someone please confirm whether a 60Hz refresh rate is possible on a 4K display connected via DVI?

Many thanks

Should be DP or HDMI 2 only.

Ok thanks. DisplayPort seems to be quite a flakey connection for me.

Have you tried a different cable? Some of the DP monitors were shipping with below par cables IIRC.

I've tried two different cables on two monitors and two different graphics cards! The issue always seems to be on waking the computer it can take a long time for the screen to come back on or it comes on, then goes off, then comes back on again. Never had such issues with DVI.

If you take out a certain pin it wont go to sleep in the first place. It is general fault with 4k and the displayport 1.2 standard. It just won't trigger to turn the signal back on when you come back to the pc after turning the tv off or changing channel. I now use hdmi 2.0 because it wakes up way more often but sometimes remains asleep still. I bought every branded displayport cable there was to come to this conclusion.
