64-bit Windows 10 1903
2080ti
nvidia 430.86 game ready driver
pg258q monitor connected via displayport

Overwatch in full screen mode: locked at 240hz. No g-sync NVidia Pendulum gsync demo: unable to select gsync option. Ticked for a fraction of a second then unticks

If I click 'stop sync' in heustacean, I'm then able to enable g-sync

Can confirm I have this issue with at least one other app using IDXGIOutputDuplication, but not with OBS's game capture.

I can confirm this problem as well. Similar computer configuration as OP, with just another monitor (PG279Q).

Can confirm this same issue with my LG G-Sync compatible monitor. Right now it seems that ScreenBloom is the only hue sync app that supports G-Sync; unfortunately it's nowhere near as good as Huestacean.

Edit: I was able to bypass this by disabling full-screen optimizations and game mode.

Breaks FreeSync too . Workaround from DavidPerez18 does not work for me

Update: After disabling the Windows GameBar and disabling the Fullscreen Optimizations per Game, free sync AND huestacean work together in almost every game :)
