Faulty HDMI 2.1 receivers
In recent months, Denon, Marantz, and Yamaha have announced or launched receivers with HDMI 2.1 pass-through and features. HDMI 2.1 is required if you want to pass-though PS5 or Xbox Series X's highest quality video signals (4K120 with HDR, 8K60) through a receiver.
German magazine Heise (or c't magazine) has carried out testing in combination with Xbox Series X and the Nvidia RTX-3080 graphics card. It concluded that the HDMI 2.1 chip in the receivers is faulty, resulting in a black screen when trying to process 4K120 with HDR and 8K60 signals.
All HDMI 2.1 receivers currently source the HDMI 2.1 chip from Panasonic Solutions (now owned by Nuvoton Technology). Heise ascribes it to a known bug in the chip that may not be fixable via firmwar

根據德國影音網站 4kfilme.de 最近一篇報道指出,
由Panasonic提供的最新 HDMI 2.1 晶片模組存有程式Bug,
德國雜誌Heise經測試,這個問題會導致 NVIDIA 顯示卡、Xbox Series X 等,
在HDMI 2.1在輸出影音訊號至AV擴大機後,會無法正確輸出 8K/60Hz 或 4K/120Hz 影像訊號而變成黑屏,
由於該晶片已被應用於Yahama, Denon, Marantz,首批能對應 8K 輸出的新款 HDMI 2.1 規格的擴大機上,
三大品牌亦正為相關漏洞作出回應及提供折衝方案。
Denon, Marantz,已對 HDMI 2.1 Bug作出回應,並提供暫時性的解決方案。
就是直接將 8K/60Hz或4K/120Hz 影像訊號再利用 eARC 將音訊回傳至擴大機上作播放。
Yahama表示正計劃盡快為相關問題作出處理。
更有傳聞講到,相關漏洞有可能涉及硬體問題,並非利用韌體更新能夠解決…
“根據c't的研究,此問題還影響了目前仍在開發中的接收器模型-包括Yamaha的Avantage,它們已經被期待了很長時間。據說Onkyo / Pioneer和Sony該公司從Panasonic 購買了上述HDMI Chip;這些公司尚未宣布任何帶有HDMI 2.1的AV擴大機。
.....................................................................................
這顆Chip只支持DSC壓缩4K120Hz却不支持未壓缩的4K120Hz,
導致接收端發生FRL(Fixed Rate Link),然後就黑屏了,
新Chip至少要等2021年中期過後才會供貨給設備制造商,
那代表消費者要到2022年才可能買到新產品,
還是有別的設計制造廠商會先發售呢? 值得再觀察...
雖然目前8k電視尚未普及,但擴大機一般來講 ,使用個5年以上是很正常的事,
5年後 我想8k電視應該非常多了吧?
我本來有考慮要入手新的8k擴大機的,剛剛才看到這個"舊聞",有嚇到...
才出的PS5不知有無影響,可能大家目前都沒有8k電視吧,算是感覺不到的故障?!!
請問如果是ps5的玩家,現在買8k擴大機是沒問題的嗎? 之前不是說無法透過軟體解決,怎麼現在又可以了? 一直想下手不敢下手...
