What monitor for GTX 1080/1070?

I guarantee you've got scanlines fellas. There isn't an X34 or Asus PG348Q out there that hasn't. They both use the exact same LG panel, gsync module etc.

I didn't think I had them either, at first, but they do appear under very specific circumstances. It's not however the end of the world as there is a way to completely mitigate the scanline issue! :) Read on if intrerested...

The 'scanlines' (most visible on left hand half of screen) only appear under specific refresh rates vs actual framerate scenarios, along with whatever overclock setting you're running in the OSD - ie OFF, or 75,80,85,90,95,100. It's not just if Gsync is on either. It's more complex than that....

Most of this is from overclock.net http://www.overclock.net/t/1573121/acer-predator-x34-owners-club/370 with a bit of my own embellishments....

...X34 owners simply need to understand that they have to adjust their monitor's overclock to match the average frame rate of whatever game they're playing (ie to mitigate scanlines, framerate dips should be no more than 10-15fps compared to the set monitor's refresh rate, as seen in table image file).

If you're averaging 80 frames per second in a game, then for that game you can to overclock to 80Hz (not just leave your overclock at 100Hz). If you're only averaging 60 frames in a game, then disable the overclock entirely (hugely important, especially as the lower the framerate, especially under 50FPS - the more prominent the scanlines are!). If you have a game in which you can run easily at 100 frames, then just max out the overclock.

I also find it hard to believe you have absolutely no backlight bleed. At all ;)? That's also virtually unheard of on the curved 21:9 34 inch LG panel that's used in a number of different models (Dell, LG itself, Acer, Asus etc etc)

I will do some tests tonight as im interested to see the results.
Did you look at the pics i linked to in the post, the BLB isnt there.

Must say, you don't really seem to be the target audience for the 1080... it's an enthusiast card designed to do the things you don't seem that bothered about. Save your pennies and go with the 1070 and one of the 27" IPS G-Sync monitors. You'll be happy.

What is the 1080 designed for then, if not 4k?

Are you saying the 1070 would be powerful enough to get 60Hz at 4k for the type of games I play?

If so, then yea no point wasting money on the 1080 ^^

Can honestly say that I've never seen any scanlines with my X34, even looking closeup at the Pendulum demo.

I must be blind :p :D

It varies monitor by monitor - the first X34 I had was so bad I could seem them 1m away, on the second one I tried it was unnoticeable unless I got really close.
 
I don't want to **** on your chips and make you start noticing something that you didn't see before :)

But, having said that, if people are generally keen to test - set your x34 to 100Hz (or as high as it will go if you got unlucky on that score) and in the pendulum demo set the manual fps slider to 40fps, look at the left hand half of the screen (particularly in any grey coloured areas) and tell me you don't see faint horizontal lines across across the screen.

Try this with Gsync on, or off too.

If you don't see these lines (using the parameters above) then you either need a trip to the eye doctor immediately, or you are the luckiest, most special person in the world ;)

And before anyone says - but I play games, I don't look at demos with my face up to the screen looking for problems - these scan lines do crop up in games too, when the conditions are as described in my post/ link to the chart above. But, they can be avoided with a bit of forward thinking and appropriate monitor overclock settings on a 'per game' basis. Bit of pain, but not too bad all in all.

ok just done this and no matter what i say you have the answers already it would seem.

screen set to 95hz - check
started the pendulum demo - check
set fps slider to 45 fps - check

Looking for scan lines - check
with both G-sync on and off - check
wife also looked for lines - check

PS. I had an eye test only a month ago and they say my eyes are perfect.
pps. no lines observed by two people, did i miss a step?

No need to get narky bud. My post, info and links above are supposed to be helpful for any x34 / Asus pg348q owners that are seeing the scan lines, and want ways to combat it.

Perhaps you really do have a golden sample? In which case count yourself very very lucky, as from my own experience and what I've read the scanlines are there on every panel (x34 and Asus pg348q), in certain scenarios.

Also, if you delve into the overclock.net thread you'll actually find a statement from Acer themselves about the scan line issue. It read.......

All,

In regards to the scanline issue, I have been provided with an update. Scanlines are an effect caused by rapidly changing refresh rate. Variations in the refresh rate create an increased holding time that results in the accumulation of an electrical charge. When this charge is released, it causes small variations in the frame that result in faint horizontal lines.

We certainly appreciate everyone’s patience and the feedback that has been provided by many of you. Unfortunately, this is a side effect for cutting edge technology and while there is not a fix to be applied, we will continue to make efforts to minimize and eliminate these types of limitations in future releases.

Thanks,
Cory
