PS5’s most recent system update sneakily added auto low latency mode support (ALLM) for compatible TVs, which automatically ensures your display is set to the optimal picture mode. However, you might have noticed that certain TV settings are now no longer available.
As shown by HDTVTest’s Vincent Teogh, several TV settings can’t be accessed or are greyed out after installing the latest PS5 system update, meaning that you can’t enable certain features like black frame insertion (BFI) or motion smoothing.
The reason is because of PS5’s new ALLM support, which forces your TV to use the most optimal picture setting for gaming and disables any video processing settings that can increase input lag.
Unfortunately, though, Sony didn’t include a toggle to enable or disable ALLM like on Xbox Series X|S, which means you’re at the mercy of these new settings unless you can disable it via your TV, if possible.

Summon the user menu by long-pressing the cogwheel button on your remote and go into the ‘General’ submenu. Click on ‘Devices’ > ‘HDMI Settings’, and turn off ‘HDMI Deep Color’, which will disable ALLM. However, if you turn off HDMI Deep Color, you’ll lose HDR support and will be locked to a maximum frame
