Those with older affected units can get hold of Sound United's external HDMI adaptor, which contains the new chip and corrects the bug. The new models can be identified by series numbers that read xxxxx700001 and upwards and should be fully functioning as they boast an upgraded HDMI 2.1 chip. Sound United, Denon's parent company, says it has been 'working tirelessly' to address this long-running HDMI issue, and thankfully receivers manufactured after May 2021 are now officially glitch-free. The glitch causes a loss of picture when signals are sent from an Xbox Series X or Nvidia RTX30-series graphics cards and affects 2020 models from the A-Series and X-Series plus the AVR-S960H. Unfortunately, despite going to great lengths to ensure its amps are at the cutting edge of video technology, Denon was afflicted by last year's notorious HDMI 2.1 bug (which also hit Denon stablemate Marantz, as well as Yamaha and others). The two models below lose most of those features but do support ALLM. In this respect, Denon excels with the entire X-range, the AVR-S960 and the limited edition A-model, all offering passthrough and upscaling, as well as will be pleased to know that across its three ranges, Denon boasts extensive support for other next-gen gaming features such as ALLM (Auto Low-Latency Mode), VRR (Variable Refresh Rate), QMS (Quick Media Switching) and QFT (Quick Frame Transport), right down to the AVR-S960H. You may think of your AV receiver as primarily an audio product, but as it sits at the centre of a home cinema system, connecting every component to the screen, it's vital that it can handle every video format that's thrown at it – or that might be thrown at it within the next few years. In just the last couple of years, we've seen the arrival of 8K TVs and next-gen gaming consoles, for example, both of which are designed to take advantage of new, more advanced video formats. Technology ages quickly, and three years can see dramatically different customer expectations.
