[patodoom]

Hello there,
Ive got a Samsung 50" JU6400 mainly used for 4K gaming only,
GPU: 2x Crossfire R9 390X
HDMI Cable: I still dont know if its 1.4 or 2.0 but based on the research that ive done it doesnt matter.
question: im only being able to run games @ 3840x2160 @ 30hz or 3200x1800 @ 60hz through one of the HDMI inputs in my TV Only Labeled in yellow (HDMI/DVI) and this is the only port that where u can enable 4K UHD colors from the tv settings.
SOOOO HOW CAN I RUN MY GAMES @ 3840x2160 @ 60hz?????
P.S TV DOESNT SUPPORT Display port connection, but my GPU has all types of connections(HDMI DVI DP AND MINI DP)


Please let me know ASAPP

The R9 390x doesn't have HDMI 2.0, which is required for 4k/60.

but it has Displayport and thats supposedly 4K/60 supportive so if i get a dp to hdmi adapter and then connect a hdmi 2.0 cable to my tv would that work??

Does your TV have DisplayPort as well? If it doesn't, you'll stil be limited to the bandwidth of the weakest link, in this case the HDMI.

well no my tv has 4 hdmi ports where only 1 can support UHD colors but when i connect my cable to it it only gives me 3200x1800 resolution running at 60 hz
and other ports i can acheive 4k resolution but at 30hz
