How to Manually Update Sony Bravia X900H to Enable HDMI 2.1 4K120Hz

The Sony Bravia X900H, or X90H in certain regions, packs a load of great features for next-gen consoles. This includes two HDMI 2.1 ports with 4K120Hz, VRR (Variable Refresh Rate), and ALLM (Automatic Low Latency Mode). However, Sony is slowly (very slowly) rolling the latest update out to Bravia X900H TVs so chances are you won’t get the update anytime soon. Luckily, users can manually update their Sony Bravia X900H TV sets using the official firmware. All you need is a USB, the firmware files which we list down below and the TV. We tested this on our set and it worked perfectly

First, you need to identify what model your TV set in to determine which region to download the update file from. There is Asia Pacific, Europe and North America. If you live in South Africa, you need to download the Asia Pacific version.

Download the update files. They range from 1.3 – 1.5GB depending on the region. Once downloaded, you need a USB stick formatted to FAT32, NTFS or exFAT. Unzip the original downloaded zip file. Inside this file, there is another zip file. This is the Sony Bravia V6.0384 TV update firmware you need.

Simply copy the zip file to the root of your USB stick and plug it into the TV. Once plugged in, the TV will automatically detect there’s an update and prompt installation. If it tells you the firmware cannot be used then there’s a high chance you downloaded the wrong region update. This happened to us the first time. The TV will restart and is now updated to support 4K120HZ alongside eARC.

Be warned though, users have reported a handful of issues with the latest update such as random rebooting, audio issues and more. However, if you simply cannot live without 4K120Hz and plan on making use of the feature on Xbox Series X and PS5 then you may want to get this installed as soon as possible. Keep in mind that this is one of two big updates arriving in the future. The other will enable VRR and ALLM.
