Nvidia Surround issue - strange line / band / tearing

[totto2k]

Hi guys,
i found this forum and hope you can help me and i can help others as well with my experience!
i have the following setup:

ASUS Geforce GTX 770 DirectCU OC (2GB) (also tried MSI GTX 770 Card - having same issues)
using NVIDIA Surround (2xDVI, 1x HDMI to DVI)
Resolution 5040*1050 59Hz
ASRock H87 Pro 4 / Intel Core i5
4 GB Ram / SSD
Win7 64bit

Screens:
2 side screens (22 inch - 1680 x 1050):
Horizontal (Analog/Digital) 31.5-82.3 kHz
Vertical 56-75 Hz

Center Screen( 24 inch - 1920 x 1200)
Horizontal (Analog/Digital) 31.5-81.1 kHz
Vertical 56-76 Hz

my problem is:
i have on one of my screens (center) a strange line / band / sort of tearing issue...sometimes this issue apears on the side screens and not on centre screen.
It appears on the windows desktop as well as ingame. (so far happening with Assetto Corsa, Raceroom, windows desktop (Chrome Browser)

please have a look at the pics!

I tried a lot already like:
-change outputs
-enable vsync
-use latest driver (337.88)

I cannot get rid of that strange issue.


And as i wrote in my setup: i am already tring the second GTX 770 (MSI and Asus)

Thanks in advance for any idea!

Hey totto2k,

I haven't seen something like this before... My first guess would be that something related to the refresh rates of the monitors is causing this. Because it's also happening during normal Windows usage.

Does it occur as well if you disable surround?

What monitor models are you using?

Cheers

Hi,
first of all,thanks for your reply! I entered my screens when i created my profile but i think this information is not visible.
so here are my screens:

Center:
NEC EA241WM ( 24 inch - 1920 x 1200)
Horizontal (Analog/Digital) 31.5-81.1 kHz
Vertical 56-76 Hz

Side (2x):
NEC E222W (22 inch - 1680 x 1050)
Horizontal (Analog/Digital) 31.5-82.3 kHz
Vertical 56-75 Hz

with surround of i did not notice issues like that.
Again,thanks for helping

this does not look like a tearing effect at all!

This looks more like a broken monitor.

If you switch the middle with a side Monitor. (mainly the cable! location doesn't matter for testing purpose) does the problem still occure ?

Or you could try clone the image on all 3 monitors! if it happens simultaneously on all 3 monitors it's a GPU problem, if not a Monitor problem.

Hi,
it is not a really broken screen - i tested a screen from a friend of mine instead of the center - same issue. Maybe more incompatibility issue than broken.
and the effect sometimes occurs on the side screens as well (i think when it is on the side screens it does not appear on the center screen) - this seems to depend on whether using windowed mode or fullscreen mode.
----
when i play Assetto Corsa in 4320*900 the effect is gone!
what i noticed:

playing in 4320*900:
the middle screen runs with H: 55Hz V: 59,8 Hz and resolution 1440*900 (i think)

playing in 5040*1050:
the middle screen runs with H: 65Hz V: 59,8Hz and resolution 1650*1050
----

interesting: playing Battlefield 4 with 5040*1050 i have no issues at all so far

Guys...i can exclude the following factors:

- Rest of the sytem like Mainboard,Ram,CPU,Power supply (i tried the card in a different PC and want to say that the same effect came up with MSI GTX 770 card)
- Windows 7 64 bit (i tried 32 bit as well)

so for me i think it can be reduced to Driver + Screens! and i think it's not the screens since those issues do not occur in single mode and another screen brings the same issue....so guys, what about that nvisia drivers! any older driver i can try?
WHY AM I SO ALONE with this issue?

i am happy for any input!

some more news:
when i run in 4380*900 (with Frame correction) and all screens run in 1440*900 mode (instead of 1680*1050), the effect is not appearing!
what should i do? keep the GTX 770 (i can still return it) and hope that this issue will be fixed with new drivers? or try another card...

Hey...one more update....when i try this https://forums.geforce.com/default/...i ... n-youtube/

(basically using the monitor inf file from side screen(s) for center) i get it working! but as mentioned in the post, this setting gets lost after reboot...
