I have to change to windowed mode, right click and move the game to the correct monitor. This also started around the time 1.19 went stable. I have Uninstaller amd reinstalled steam, Dayz, verified game files and made sure files in config folder are not set to read only. It saves my controls setting and keybinds but does not save which monitor dayz was last played on or the setting for what to play in background. I set it to game and sound but it always goes back to default.
