Reports of PS4s with faulty HDMI output ports are “isolated incidents”, Sony has claimed.
IGN reports that a handful of early PS4 owners scattered across the internet – including systems received by both IGN itself and Kotaku – seemed to have a fault with their HDMI port that prevented the console from outputting a reliable signal.
Sony Studios boss Shuhei Yoshida has said that Sony is investigating the issue, but that such reports should be considered as “isolated”.
