One of the selling points of this generation of ps5 is the support for 4K 120Hz and 8K 60Hz output. With such high bandwidth, Sony decided to launch HDMI 2.1 interface, and even boasted about several TV sets with HDMI 2.1 interface.
However, according to Christopher Mullins, product manager of Sony digital and home theater, HDMI 2.1 interface does not have the potential to be a game changer. He stressed that the performance baseline of the new generation of mainframe is still 4K 60Hz smooth games, and most games can reach this level.
This point of view is also reasonable, because it is not Sony that determines whether 4K 120 frames can be achieved, but the optimization of developers. According to the information available at present, there are not many games willing to unlock.
In addition, Mullins trading Sony's latest generation projector product line does not have HDMI 2.1 interface, but all HDMI 2.0B, that is, support earc enhanced audio return. The flagship vpl-gz380 has a brightness of 10000 lumens and two HDMI 2.0B interfaces. The input delay in game mode is only 13ms.
