Gsync simply not working/Screen Tearing issue

[the7isbest]

As the titles says, my Gsync doesn't seem to be working lately. I see considerable tearing in most games, even though all signs point to the fact that my Gsync is indeed enabled. I have no idea what's going on. Vsync doesn't even help with the screen tear.

hm.... you say even V-Sync doesn't work?
is this in general for all games? or for only specific ones?
are you on windows 10?
what monitor do you have (model number please)
and what cable type are you using to connect to the monitor?
and just in case we might need it, what GPU do you have as well? Specific model please (i.e. - not just a GTX 1070 but an ASUS ROG Strix GTX 1070)
