前几天就看到了，TG没人提起，特地转一下怕有人踩雷
由于松下提供的芯片缺陷，新的支持HDMI2.1的功放集体吃瘪，4K/120hz 和8k模式会黑屏，包括天龙/马兰士（已官方确认），雅马哈，大法和安桥。目前还没有解决方案，可能永远都不会有。目前要么通过ARC/eARC回传，要么4K/60hz。

SoundUnited的声明（马兰士/天龙的母公司):
Sound United's official, unedited response to me and their customers about this issue below:
---
SOUND UNITED'S RESPONSE
Some new gaming source devices that support 4K/120Hz output may not work fully with Denon (or Marantz) 8K AVRs. You may discover this incompatibility issue due to a HDMI chipset mismatch between the devices. When the affected system is connected to the AVR via 8K HDMI input and set to output at 4K/120Hz, and the AVR’s 4K Signal Format option is set to “8K Enhanced,” you may not see the system’s source video on their display, and may not hear the system’s source audio processed through the AVR. This problem is only present when a display that supports 4K/120Hz is used.

We are currently investigating the issue further and will offer a permanent solution at a later date. Meanwhile, we would like to provide a couple workarounds to prevent the issue in its current state:

You can connect the system to the display directly via HDMI and use the display’s ARC/eARC functionality to feed the native audio back to the AVR using the connected HDMI cable between the AVR and display. This will allow users to decode the native audio format sent from the source. With this method, the display’s CEC/ARC option must be enabled as well as the AVR’s HDMI Control and/or the AVR’s ARC option. In the AVR, this option is located within the GUI under “Video – HDMI Setup.”

Another workaround is to leave or change the source’s video output to 4K/60Hz instead of 4K/120Hz until a permanent solution is available. This will ensure reliable communication between the source, the AVR and the display. The source’s default is set to output at 4K/60Hz, so if no change was initiated out of the box, then nothing further needs to be done.

We apologize for this inconvenience and we are currently working tirelessly to release a permanent solution so you can enjoy the 4K/120Hz experience using the latest sources with your AVR. We will have an update soon regarding the timeline of a permanent solution. We appreciate your patience.

果然不能买太早，等ps、xb出来的时候经过大量人有料测试之后再买才安全，包括hdmi2.1电视。

等大量有料测试后就又是hdmi 2.2了...

2.1的参数够我用很久了，毕竟我现在4k hdr都没用上。

这么严重的问题所有厂商都没测试过？

不是没测是不敢公布吧

很简单，没设备没条件测

PR话语，理论上换芯片可以..

FML, 剛訂了Yamaha 的5.1還在路上...試完喇叭跟新主機就把退了。。

可能召回换新，然而国内估计要杯具

收到Yamaha, 我要連電視的設備不多，感覺對我問題不大。先連電視然後EARC 原生音源到receiver接喇叭. 這鏈接本身就佔用一條 HDMI, 電視還剩3條可以用。其他沒有4K/120的接receiver的HDMI。

有可感知的延迟，看视频无所谓，大部分电视机有自动同步，玩游戏么。。。。。

其实没什么问题吧，能上4k120hz的游戏，新主机上不存在的。
