“Can this TV now support 4k @ 120 Hz output using the HDMI 2.1 port?”

• Yes it can. I had to download the patch to a thumb drive and manually update the tv. For some reason, the auto update did not work for me last month. Sony may have fixed this already. Hope this helps

• Hi macfan, Thanks for your inquiry about the XBR55X900H. A new update was already released to add support for 4K 120Hz signal format. You may refer to this link for more information: https://www.sony.com/electronics/support/lcd-tvs-android-xh90xx_x90xxh_x91xxh_xh92xx-series/xbr-55x900h/downloads/00017089 Regards, ~Ralph

• No it does not. It still only supports 4K @60Hz. Maybe with the next firmware update it will.

• Yes. I have a PS5 with two games COD and Dirt5 confirming with HDMI 2.1 in the specific HDMI input that it is supporting 120fps.
