So, if a better cable is going to help, this is about as good as it gets. I'm not optimistic though.
I just wanted to try something before doing a return. One nice thing if I have to do a return, buying the monitor got me a free 6 months of NewEgg Premier so I should have free shipping on my return.
Oh this is nice. I was not aware of a database nor thought to look up datasheets for these cables. Thanks.

It's very frustrating tbh - a perfect monitor tarnished by this one thing! But if I can't use G-Sync because it degrades image quality then I may as well use my Dell!
To be clear, the problem with the first ROG swift was the appearance of alternating correct and dark lines of pixels along the vertical which was an order of magnitude worse than the "horizontal scanlines issue" with the X34 (speaking based on the pictures shared on this thread). Ofcourse, that does not make the X34's problem acceptable in any way.
Moreover, the guys at PCPER pegged the ROG SWIFT problem (which also manifested in other TN G-sync panels) as one of a few "TCON or Timing controller related artifacts"
. They also have stated that this TCON problem should only affect TN panels. I'm not sure what the reasoning behind that is but they said that the issue is independent of the G-sync module. This makes sense because the swift's issue was independent of whether G-sync was On or Off.
If what they say is true (Swift's issues were TCON/TN related only and not related to G-sync), then the cause of the "horizontal scanlines issue" with the X34 cannot be the same. So far, everything points to the G-sync module being the cause for the X34's issues since turning on G-sync causes it.
EDIT: In summary,
ROG swift vertical lines --- caused by TCON+TN only. (unrelated to G-sync module)
X34 horizontal lines --- probably caused by G-sync module. (not
verified.) (unrelated to TCON)Edited by Mountainlifter - 11/4/15 at 9:40am
