LG is in the news over this. The XBox One 4K discussions are incendiary. I won't go there but ask LG directly for a fix or consider returning it. It looks like this is a work in progress.
Just bought a new LG 55UH661V 4k TV. I'm trying to set it up to show 4k from my PC through HDMI port, but display settings advanced options offers no option above 1920x1080 (recommended).
I'm on windows 10 64 bit
Sapphire R9 270x 4gb
2.1 HDMI Cable
Crimson 16.6 (latest)
all elements should be capable of 3840x2160, but I have no option above 1920x1080.
I've also got a BenQ GW2760 connected through DVI, working fine at 1920x1080.
Radeon setting say VSR is not supported for the TV.
Any idea's what I'm doing wrong?
