Could someone with a LG B9 and RTX 3080 test 4K@120hz HDR please?

There has been lots and lots of contradictory info regarding the ability of the B9 to weather or not support 4K @ 120 hz with HDR

Now that there are HDMI 2.1 video cards out there, can someone PLEASE help me test that?

I have the B9 but I don't have any HDMI 2.1 source to test (3000 series was too much for my wallet)


AFAIK the B9 was listed for official HDMI 2.1 support on all 4 HDMI ports on LG Official website, so theoretically you can just plug the video card to the TV itself and it should just work with 4K 120Hz

I found no info on this either.


The LG OLEDs are having issues with the 30 series cards and it looks like LG is addressing it.  They don't mention the B9 but they don't leave it out.

Here in my favorite TV reviewer doing a video on it.

Just got my MSI 3080 and I have a B9. 4K 120hz HDR works fine except you have to turn off GSYNC. In fact GSYNC needs to be turned off no matter what refresh rate or HDR other wise you get black screens, artifacts, etc. 


Hope this gets fixed.
