I’m gonna take a look at it. When I asked when I tried to find a new TV, they told me that basically all these new features like VRR, or ALLM were for 2.1, but if you say that Free-sync is for 2.0 on your monitor, I will look into it.
Wait a minute, I may have found something. Apparently HDMI 2.0 may have VRR support if the manufacturer planned to support that feature. Some screen or TV may support VRR even with a HDMI 2.0 connectic as a result.
The LG 27UN950-B has native FreeSync Premium Pro support to reduce screen tearing, and it’s certified by NVIDIA to be G-SYNC compatible as well. You need a DisplayPort connection to achieve its max 144Hz refresh rate and G-SYNC support. Its FreeSync VRR range over a DP connection is between 50-95Hz. Over HDMI, you can achieve a max refresh rate of 60Hz and it only supports FreeSync.
Though, I would also advise to contact LG to be sure on that one.
my Samsung TV supports FreeSync with 1440p and 120Hz over HDMI 2.0. So it is possible. On some FreeSync TVs you have to enabe 4:2:2 color compression because 1440p+120Hz+HDR is on the boundary of HDMI 2.0 bandwith.
