@Simon T: I'd definitely recommend heading to Home > Settings > General > External Device Manager > Game Mode Settings > Game Mode, and setting this to 'Auto'. Now, when you open a game on your connected PS5, Game Mode will be enabled, and will optimise the TV for a better gaming experience (including improved frame rates, input lag, and HDR). Don't forget to head into the Video settings on the PS5 itself to explore the available options, as you may need to manually enable features such as VRR (for AMD Freesync) and HDR from here. Enjoy!
