With the Denon X4800H has expanded its feature set for the growing 8K video and next-gen gaming market. The previous lineup of Denon home theater receivers introduced limited 8K processing, along with gaming features like Variable Refresh Rate (VRR), Auto Low Latency Mode (ALLM), and Quick Frame Transport (QFT). These features have been applied to the AVR-X-4800H on all seven HDMI inputs and two of the three HDMI outputs, so you can accommodate even more modern tech into your AV Receiver with 3D audio system.
