780 Ti GPUs don't need the patch at all if you're using the NVIDIA Control Panel to add custom resolutions. The regular patch is needed if you use CRU instead.

At 120hz only a few horizontal green lines were appearing and the only adjustments I made were to the Total Pixels and the two boxes above it, I changed Horizontal to 2620 and Vertical to 1448, I changed the default F.P. from 3 to 1 and default S.W. from 5 to 1. Either way I kept getting the tiniest of occasional horizontal green lines - and I mean occasional, but they were there. I don't know what else to change so I simply lowered it to 119hz and it has been running great for extended gameplay. I would love to get it up 1 more hz but I know it's not completely necessary.

I'm surprised you were able to reduce the horizontal total so low. Do you have the single-input version of the X-Star with dual-link DVI only (no HDMI or DisplayPort)? Most people could only get 2652. You might be able to go even lower if you set the horizontal front porch and sync width to 8. You should be able to reduce the vertical total to 1445. That alone might be enough.

The QNIX/X-Star monitors supposedly have a darker gamma at higher refresh rates, so that's one way to tell. You can also check the frame rate with vsync on, but the video card has to be powerful enough to render enough frames.
