LG CX Flickering Instant Game Response Launched On PS5

    LG CX Flickering Instant Game Response

    When playing games on the PlayStation 5, I found that the system was no longer working well with my LG CX TV. I kept getting a notification at the top of the screen to say “Instant game response is launched”. This often appeared when playing games on PS5 but this kept showing up over and over, it would never stop.

    For this instance, I was playing Destiny 2 and while I was able to play other games without any issue, I was unable to play this game as the HDR notification kept showing up and the notification said that Instant game response was enabled would just keep popping up on the screen. This would often cause the screen to go black and flicker. Incredibly annoying and it made it very hard to play any games.

    PlayStation 5 VRR Support

    The PlayStation 5 received an update to support VRR. This feature shouldn’t cause issues with the LG CX TVs but unfortunately, it does cause trouble, in the form of a constant popup notification to let you know something has changed with the video input.

    The solution to this issue is to disable the VRR feature on the PlayStation 5. Having turned this off, I found the issue was immediately resolved.

    Toggle HDMI ARC

    There are some people who have reported that there can be some issues using HDMI ARC when playing some games with the LG CX line of TVs. HDMI ARC will allow you to output audio via a HDMI port on the TV. It is possible to toggle this audio quickly via the audio settings menu on the TV.

    If this does not do the job, you may have to consider changing the HDMI port / cable to make sure it is not the ARC port on this TV.


    1. I experienced similar issue with my LG TV, originally everything was fine. But after some updates, it was flickering on all screens (game and main manual). It really took me awhile to navigate to the VRR screen (as the screen is flicking and stayed black for most of the time) and found that VRR was not even enabled on my TV.

      I just tried my luck by inserting another HDMI cable and it resolved my issue magically…

    2. Mr Dan Hastings, Sir. Thank you a thousand times. When i switched the game response thingy off the screen was al glitchy it hurt my eyes. Now i can game in peace with a smile on my face
