G-Sync

Hey all.

So i didnt find any sub forum topic named G-sync O.o

I have Asus ultra wide PG348Q and gpu RTX2080TI.
Now i read somewhere Nvidia stoped support turbo boost so im stuck at 60hz (get black screen when turbo enabled error message no signals / tried other cables).
[Edit] Found its a windows issue causing this:

Sooo . . should i disable G-Sync to feed screen higher frames?

Thanks for assistance

@Ragnarok:

Thanks for your input m8. Now fooling around in the settings it looks like i can have boost enable up to 90hz. At least thats something, all above and i ge a black screen.

The answer was in the cable.
I had a 3m one, changing back to 2m solved it. However, the 3m did work earlier, for a year and a half so i had no reason to doubt that.

Posting this if anyone in the future gets same error.
