Legion Y740 G-SYNC rarely working

2019-10-01, 18:00 PM

So the problem is that G-sync is finiky. It rarely appears and when is is working several things make it dissapear again. Namely a new GPU driver, using hybrid mode (and then switching back), and maybe even some Windows updates. Does anyone have any idea on how to make this feature available forever?

Hi abognasar6! 


Welcome to the Lenovo forum discussion! 


Just to confirm, does the G-Sync feature worked before on the Lenovo Legion Y740? If yes, please try opening the Lenovo vantage app https://vantage.lenovo.com/?CID=ww:lenovosocial:20x9m6 and check for a system update, then install them all. After that, restart the laptop and check the G-Sync again. In addition, we found a similar discussion from the Lenovo forum https://forums.lenovo.com/t5/Gaming-Laptops/Y740-w-1660ti-Gsync-is-not-available-and-does-not-run-in/td-p/4503945?CID=ww:lenovosocial:20x9m6 and try the checking the NVIDIA Control Panel, then verify if G-Sync is enabled or not.
