Cable Matters

With subsequent-gen consoles hitting us, the launch of fancy, new graphics cards just like the Nvidia RTX 3070 and RTX 3080, also as AMD’s Big Navi launching tonight, you’d expect newer home cinema audio/video receivers with HDMI 2.1 connections to be ready for the juicy ultra-high res goodness. Unfortunately, this is not quite the case.

The new home cinema receiver devices from Denon, Marantz, and Yamaha are meant to be ready to output videos in 4K120 or 8K60 via HDMI 2.1. Unfortunately, it tests (via Heise online, Tom’s Hardware) on Denon AVR-X2700H models have revealed a bug with these models, all supported new Panasonic chips.

When attempting to route the Xbox Series X or Nvidia graphics cards through the new receivers in 4K or 8K, using the HDMI 2.1 connection, the receivers were unable to undergo the image, only throwing up blank screens.

Lower resolutions worked just fine, but that sort of defeats the thing of employing an HDMI 2.1, doesn’t it? or maybe the RTX 3090’s signature 8K performance. don’t be concerned, for those using direct HDMI 2.1 connections to ultra-high-resolution displays, there should not be an issue; only those using the aforementioned home cinema systems are likely to encounter problems.

It’s worth noting that it had been a pre-production model of the new Xbox magazine was using, with the ultimate iterations yet to be tested through the pre-production model is predicated on the ultimate hardware designs, so there are likely to be issues there, too. it is also likely that Yamaha products will run into problems because the same chipsets are used for its devices. Sony’s PS5 is yet to be tested, but it’s actually expected to figure just fine, consistent with the people that did the first testing, which is weird seeing as it’s supported similar hardware.

Looks like the matter is thanks to a mixture of poor implementation of the transmission variant “Fixed Rate Link” (FRL) and issues with DSC (Data Stream Compression). consistent with heise Panasonic says the matter “cannot be corrected with a firmware update,” either.

you will need to wait and see how Panasonic plans to affect the matter. In the meantime, it has outlined some potential workarounds within the original article, but we may need to wait until next year for working replacements to require the place of those faulty models.
