A:Answer Hi there,
Thank you for reaching out! We understand you’re experiencing random black screen interruptions while using your OLED48B4PUA with your PS5, especially in Game Mode at 4K 120Hz. This could be due to a signal handshake issue between the TV and the PS5, particularly when switching between content types (such as HDR). We recommend ensuring that your TV’s firmware is fully updated and checking that the HDMI Ultra HD Deep Color setting is enabled for the HDMI port connected to the PS5. Additionally, try using a certified high-speed HDMI 2.1 cable if you’re not already. If the issue continues, please send us a private message on Social Media @LGUSSupport, and we’ll help you further troubleshoot this.
We appreciate your patience, and we’re here to assist you!
