I have a LG B9 and a hw-Q70R. With ARC (not eARC) I had the same problem, but a few months ago hw-Q70R got a firmware update to support eARC (use SmartThings app to update the soundbar). Now with eARC, all my external source don't have audio delay through soundbar anymore (Nintendo Switch, Chromecast etc.). LG's internal apps (Netflix, YouTube) still have about 150-200ms audio delay through soundbar. If you're connecting PC to TV and haven't upgraded your soundbar to eARC, there's a good chance that upgrading it will get rid of the audio delay

Same problem bothered me after I switched to DP monitors. I found a solution that works for me: instead of turning off the monitors by pressing the button on monitor, I turn off screen from windows. I'm using a lenovo PC and its Power Manager software has a feature to put a 'power off monitor' option if i rightclick desktop. I believe for other pc you can download a tool like NirCmd or Monitor Off to do that. When I turn off monitor in this way, my monitors would go to sleep mode but stay connected; And when I wake them up all the windows stay where they were.
