Dolby Vision gaming with 120hz (HDMI 2.1)?

Hi thanks I have played with this for sometime, There is a green check mark by ALLM. ALLM is supported by a 2.0. 2.1 hdmi only exception is no 60@120hz.

HDR10 is also has a green check without a 2.1 input there are no limitations as my input during game indicate HDR10 is working. I can do this by checking my inputrs throught TV settings (Auto select for 2.0 enables ALLM Feature on My TV). Dolby Vision for games does not work when ALLM is enabled.

Everything is green on 4K EXCEPT for 120hz because of the lack of 2.1 port. When I turn off ALLM through XBOX setting Dolby vision works.

The HDMI 2.0 won't affect the Dolby vision, right?

Can I still use the HDMI 2.1 in my TV or do I need to use the old 2.0 HDMI?

but if the video feed is not going though a HDMI 2.1 port, the signal / bandwidth to the TV is limited by the HDMI port the it uses, be it a straight connection or some sort a splitter,

4K 120hz requires a HDMI 2.1 port, no HDMI 2.1 ports, no 120hz at 4K

that monitor supports 120hz and freesync, you don't need hdmi 2.1 for 1080p and 120hz with freesync at all.

you need hdmi 2.1 for 4k at 120hz with vrr.

I have that screen and its fine for most gaming uses.

that screen has console mode for 120hz, and works fine.

Honestly the Dolby vision would be the best option until more things are supported that utilize the 3k 120hz rate. Dolby vision will definitely increase the quality of games and apps
