A DisplayPort 1.2 to HDMI 2.0 adapter should work just fine and will support 4K @ 60Hz. Just make sure you use a certified HDMI 2.0 cable as well. Both the adapter and cable can be purchased on Amazon now. Also, I recommend you verify the HDMI 2.0 port is configured for 2.0 and not 1.4b within the TV settings menu.
1) it sounds correct. but doesnt work.
1a) dp and hdmi both look for a handshake but since they speak different languages it isn't there.
1b) so we are still waiting for a active dp/mini dp to hdmi 2.0 adapter.
1c) accell and club-3d both say an adapter is coming before end of year.
2) technically there is no hdmi 2.0 rated/marketed cable, BUT
2a) current "high speed" rated cables are only 10Gbps
2b) 4k 60hz needs a 18Gbps or faster rated cable
2c) monoprice has affordable 18Gbps cables. or monster sells 27Gbps cables
the dp and mini dp adapters from uptab do work, according to multiple forums/threads i am on. they are also the same product as the allreli brand on amazon, but the amazon ones are A LOT LESS.
the weird thing is the mini dp version on amazon stopped selling a 4k 60hz version. check out reviews, early reviews said it did work. and newer reviews state the latest model no longer works. i also got secondary confirmation on another forum about that fact that they must have changed the model a bit and it no longer works.
