If they get a fix out later sure, I will give it another go, but at the moment there is absolutely no word from ACER that they will address this issue.

That's just the worst, are they oblivious or intentionally ignoring us, or actually investigating it but not saying anything, who knows? You'd think companies would know by now that people just like to know what is going on...

tbh they don't wanna say anything until they have a resolution, which they don't at this moment. any honest answer from them would just be: we're investigating with nvidia (which they have already mentioned). look at corsair with the hg10 n980. they never explained what was wrong with the manufacturing process that caused the part to be delayed for 2-3months.. once they released it, everybody stopped complaining and moved on to the new issues.

Have they acknowledged the horizontal line problem? So far I thought they only mentioned they are looking into the back light issue...

Also, leaving myself a note about something else to test, unplug secondary monitor and see if the lines are still there. Does anyone else with the line problem have more than one monitor connected?

Where is the MFG date exactly ? On the monitor or the box ?

Ok, Vega to the rescue. wink.gif

So it's been nagging me why the horizontal lines are the most visible in the pendulum test and almost non-existent in Windows 10 and some other games. I've already tested that refresh rate does not affect the horizontal lines and they were the same at 60 Hz and 100 Hz.

To my surprise in my testing, it's not refresh rate but FPS based! So the pendulum test starts by default at a really low FPS. While comparing the X34 with my TN swift, I selected the option "Show Test Pattern", which brings up a grey that makes the horizontal lines most apparent. Then, I selected "FPS sliders". Instead of running the ~35 FPS or so that the pendulum test starts out at, I put the max at 100 FPS and the min at 95 FPS. Voila, the horizontal lines virtually disappeared. There is still just the slightest of lines if you look super close, but definitely nothing you would notice at a normal sitting distance. I'd say they dropped by about 90% in strength. thumb.gif

So there you have it, just keep your FPS up towards the monitors max refresh rate and the problem is all but non-existent. yessir.gif

So you are telling me that I need to swap my GTX770 for a watercooled GTX980ti? It's a bold plan, but it might just work!

Both, but I got mine from the box, the label with the serial number on it, bottom left corner.

I'll have to mess around with that and see what it does. That muddies the water even more regarding if this is a universal problem or not. It also sucks for me because even if I had SLI Titan Xs instead of my single GTX 780 I still wouldn't have much better FPS in DayZ. tongue.gif

OK, I can confirm this as well. Has the same effect for me. However, this is not that great news. If you are running your monitor at max refresh rate anyway, then you may as well turn off GSYNC, because it is not achieving anything.

What does GSYNC do at the top end of the refresh range anyway? I know it does clever stuff at the bottom, with frame doubling and so on, but what happens at the top end? Does it start throwing frames away? Is it in effect vsync at that point?

In short the findings seem to be, if you do not use GSYNC, you get no lines. Also the less you use GSYNC, the less lines you get. That's not fantastic news if you want to use GSYNC, which presumably you do if you bought a GSYNC monitor.

Especially if you bought a G-Sync monitor specifically to help make the most out of low frame rates... mad.gif
