We recently reported that new receivers from Denon, Marantz and Yamaha, which claim support for HDMI 2.1, actually have very limited support for this standard and cannot output images in 4K120 and 8K60. Yamaha has advised that it will address this issue.
The company representatives clarified that the issue will affect the RX-V6A, RX-V4A, TSR-700 and TSR-400 receivers. According to Yamaha, at the time of the announcement, the company promised that receivers will receive full support for modern video formats with software updates, and now the updates will also take into account recently identified problems.
Yamaha’s decision seems strange, given that the problem of the chips used in the receivers is not in the software, but in the hardware part, and most likely it will not be possible to fix it with updates. After repeated inquiries, Yamaha representatives said that they could not yet say what exactly the solution to this problem would be, but promised that they would certainly solve it.
