“How do I get the TV to show 4k with HDR 10 at 120hz? I got a new ultra high speed cable rated for 8k at 60hz and 4k at 120hz, and my Xbox Series X should be able to run it just fine. But the console says the TV is not set up for it.”

Hi Sean, Thank you for your question! To enjoy 4K at 120Hz with HDR10 on your Sony BRAVIA XR8B using your Xbox Series X, you’ll need to ensure both the hardware and the software settings are aligned. Since you already have the correct Ultra High Speed HDMI cable, the issue is likely related to the port selection or the internal "Signal Format" settings on the TV. Please follow these steps to resolve the issue: 1. Update Your System Software: Ensure your TV is running the latest firmware to maintain compatibility with next-gen console features. Navigate to Settings > System > About > System software update. 2. Check Your Port Connection: While the TV has multiple HDMI ports, only HDMI 3 and HDMI 4 are HDMI 2.1 compliant. These are the only ports that support 4K at 120Hz. 3. Configure the HDMI Signal Format: By default, Sony TVs often set HDMI ports to "Standard" to ensure compatibility with older devices. You must manually unlock the higher bandwidth for your Xbox. Using your Sony remote, go to Settings > Channels & inputs > External inputs > HDMI signal format > Choose the specific HDMI port (3 or 4) where your Xbox is connected > Select Enhanced format Once these settings are applied, your Xbox should detect the 4K/120Hz capabilities automatically. If the issue persists after following these steps, please contact our technical support team for further assistance at: https://us.esupport.sony.com/support/s/support-contact?language=en_US&category=tv Thank you for choosing Sony!
