Now i couldnt give two ****s if the pendulum test does that as long as my gaming doesnt.
Can you guys share your findings after updating the drivers too thanks
This is exciting news if driver updates are resolving the problem. We need more people (@drfish, you play fishing planet too) to confirm this to ensure it's not a one-off.
I knew that Nvidia was not just doing variable refresh rate but also doing some algorithms in the background to vary the pixel response too. And I suspected that this algorithm (not being tuned to widescreen or some other reason) was messing with the X34 and producing the scan lines. I assumed that the dynamic pixel response was coded in the G-sync firmware but if it is also in the drivers, it could explain how your game doesn't show the lines anymore.
(This is all speculation.)
EDIT: Wait, you said you installed the latest drivers. Did you remember to turn on G-sync in the NVCP after installation before going into the game? Just making sure

I am not sure if the issues we're seeing with the X34 are panel related or perhaps more likely due to the fact it's a 60Hz native panel that has been overclocked to within an inch of its life. This can't always be a good thing.
As far as I know, every monitor maker has to send their panel to Nvidia for G-sync certification before they allow it to be sold as a G-sync monitor. (source: one of the PCper videos with Tom Peterson).
So, I think they must have taken this panel through its paces for overclocking to 100Hz with G-sync. But just like Overclocking a CPU varies from unit to unit, despite their testing on a few panels, not all units coming out of the assembly line will be equally overclockable. In the case of these monitors, I don't know what is limiting the max refresh. G-sync electronics, panel properties, or DP bandwidth limitations?Edited by Mountainlifter - 11/4/15 at 8:26pm
