When launching the game, either immediately after the sign-in splash screen or after a few minutes, both of my monitors turn black and flicker with the message "OUT OF RANGE." I can still hear audio, and the only way to stop it is to force shut down the PC. It started around last year and only used to happen infrequently after 1-2 hours of play. I'm using a GTX 970, i5-4690k, and my main monitor is 1920x1080 144Hz. I play a variety of games, and this problem is specific to Destiny 2. So far I've tried: Verifying the game files Updating graphics drivers Checking that my resolution and refresh rate are set to their native values Unplugging monitor cables and plugging them back in Deleting cvars.xml Starting the game windowed
