I know this because when my old swift went down, it started to display the same horizontal lines and flickering when GSYNC was activated, but was otherwise fine. Now with the x34, the entire image is nice and clear EXCEPT for the far left side of my screen, there is a small patch of an area that displays these horizontal scanlines... I was able to sweep my camera over the city, showing the clear LACk of these lines, but the moment it would reach the far left, into this patch, you would see the horizontal image destroying lines. I tested this in another area, where my FPS was a solid 100, and the lines were so hard to see. It was debatable if they were even there. Back to the sign, where my FPS drops to 50 ish, and the scanlines are back, but only within that patch. It IS annoying, but so minor I will overlook it unless it gets worse, or the patch grows. It's only visible with GSYNC active too. The problem remains at 80hz, or 100hz with GSYNC. I did not test 60hz + gsync.
Thanks for this - this is the first time I have seen anyone else with my problem. 100hz works fine. BLB is fine. No coil noise. Everything perfect (only gets 95hz on my GTX770, but 100hz on a friends GTX980, so a hardware swap will fix that).
However, if I turn on both OC mode and g-sync I get those scanlines everywhere. g-sync with OC off? Fine. OC mode at 100hz no g-sync? Fine. It seems to me that Acer's overclock circuitry is affecting the g-sync module in OC mode.Warning: Big images of problem ahead! (Click to show)
To be clear:
WIthout g-sync it looks like this. Don't be fooled by some lines, those are just the camera focusing on a row of pixels.
And with g-sync (you are looking at the bands of light and dark not the individual pixels):
It is one of these really annoying problems that once seen you cannot unsee. So I have applied to the retailer for a return/replacement, unless anyone has a bright idea.
