Gaming Features
Denon AVR-X4100W supports Auto Low Latency Mode (ALLM) for lag-free and smooth gaming.
- Auto Low Latency Mode (ALLM): Auto Low Latency Mode enables the ideal latency setting to automatically be set allowing for smooth, lag-free and uninterrupted viewing and interactivity. When the receiver detects a gaming signal it will enter ALLM. The signal will also be sent to the TV causing it to automatically switch to a low-latency, low-lag mode for gaming. Some functions will not be available on the receiver and TV during ALLM.
