I did end up getting the firmware for the adapter today and it didn’t help. Also, I have an ASUS DirectCU II Top version of the R9 280X, it comes with 2 DVI, 1 HDMI and 1 DP. I’m using a Mediabrige Ultra Cable that’s rated for up to 18GBps speeds and is compatible for up to 240Hz refresh rates. I’d like to also note that I haven’t gotten it to successfully show 60Hz in dxdiag since the time I explained in my earlier comment. I apologize for any rudeness, I’m just extremely aggravated over this because it’s SO close to working yet it just won’t budge where it needs to. Would you happen to have heard of any fixes people have undergone pertaining my specific TV model? The firmware is (from what I gather) the newest one to date and has caused problems even for nVidia cards that have HDMI 2.0 out ports.
