ALLM (Auto Low Latency Mode)

The so-called Auto Low Latency Mode, or ALLM for short, is a function used in many modern televisions and video game consoles to minimise the delay between the input of a signal and the optical output on the screen – also known as latency or input lag – and at the same time improves image synchronisation.

More clarity with gaming optimisation

Using ALLM, the TV automatically detects modern consoles such as PlayStation 5 or Xbox Series X|S and switches to a display mode optimised for gaming, often referred to as game mode. This enhances the experience by minimising the delay between pressing a button on the controller and the response of the screen.

An additional component of the feature is the dynamic refresh rate adjustment – also known as Variable Refresh Rate – of the graphics card and TV panel. This avoids annoying staircase effects, also known as screen tearing. This is a particular advantage in titles where the pace is generally high and thus a good overview and quick counter-reactions are required.

Unfortunately, not all TV sets support this functionality. Usually, this includes low-cost basic models that are aimed at ordinary consumers who do not have any special demands on a television set. As a result, those TVs often offer a rather modest package of features. HDMI 2.1 is a basic requirement here, however, and is implemented in many cases only from the mid-price range upwards.
