Since I connected my LG OLED C9 (HDMI) besides my Acer VG270U (DP), VSync is not working on startup. I have to change the setting to something different and then back to “automatic” to enable it. There is no difference, if the TV is turned on/off during startup. It even happens when the TV is disabled in the display configuration. So, it just needs to be connected to produce this phenomenon.
Has anybody an idea what the problem could be? In a pinch, an autostart-script automatically switching settings would be ok.
