Hi All,
I am stumped? I cannot get 4K120 with my LG C9 with PC. Please see my below setup with links to where I purchased cable and their official sites specifications. I am not sure whether it the LG C9 or my cables. I purchased most of my cable after June 2020 and the HDMI true certification has only recently been released officially from HDMI.org. They don?t have a list of certified Ultra High Speed (HDMI 2.1 48gbps) manufacturers, only adopters.
PC:
AMD 5900X
Gigabyte X570 Aourus Master
32Gb Ram
XFX Radeon RX 6900 XT Speedster MERC319 Black (HDMI 2.1) - Adrenalin 2020 Edition 21.1.1

I have tested with all the above cable with the same results, connecting from the 6900XT to HDMI 1 on LG C9 at 4K.
In AMD Radeon Software Display options, I have tried Colour Depth (8/10/12 bpc), Pixel Format YCbCr 444/422/420 & RGB 444 Full RGB. I have also tried with HDR on & off in Windows.
Under Windows Display settings ? Advanced Display Settings ? Display adapter properties for Display 1 ? Monitor Tab, when changing from 60 Hertz to 120 Hertz at 4K, the screen goes black and has no signal and reverts back to 60 Hertz.
On the LG C9 HDMI diagnostics (Settings-All Settings-Programmes-High light Programme Tunning & Setting and press 11111-select HDMI mode), it shows the following example:
General
Port: 1 HPD : High 5V : High, RxSence: HIGH
3840x2160P @60.00Hz YCBCR444 12BIT BT202_RGBORYCBCR
No_Audio 0Ch 48000Hz
HDMI Mode: HDMI, HDR Type: HDR10
Video(Link)
Active Res: 3840x2160, Total Res: 4400x2250, Pixel Clk: 594.Mhz
HDCP 2.2
ENC_EN: TRUE, Status: PASS
I have LG Picture settings as:
? PICTURE

? HDR Picture Mode ? Standard
? AI Picture ? Disabled
? Advanced Controls
o Dynamic Tone - On

HDMI ULTRA HD Deep Colour ? On

What are you suggestions or recommendations?
Do you think it my HDMI cables?
Is it a setting issue on the C9 or a windows setting?
What I am aiming for is to have my 6900XT connected to HDMI1 on LG C9 in order to play 4K120 games and with HDR and freesync if possible.
Then I would like to get eARC working connecting from HDMI2(eARC Port) on LG C9 to HDMI ARC main port on Onkyo RZ720 with updated firmware, which is also not working, but that a separate issue.
I?m not sure whether I also need to use CRU (Custom Resolution Utility) in order to get this working correctly and delete resolutions I don?t want and setup freesync that way.
I am from South Africa so access to HDMI 2.1 cable extremely limited, and rely on international retailers like Amazon/eBay/AliExpress, although very costly, my only option here as I am desperate to get this working after spending soo much money in hopes of having working. If you have some cables that you have working in this situation/setup with links for international buyers would be appreciated.
Your help will be appreciated!!
