Screen Tearing with Identical Monitors

[Ben Lewis]

Hi there,
A couple of months ago I got a second monitor, it was not the same as the first monitor, and I was having bad tearing all the time, really bad tearing. So I decided to remove it, a couple days ago I got a second monitor identical to the first, the ASUS VC239H. And everything was fine until now, when i'm getting really bad tearing even on the desktop, screen flipping and turning and blacking out for a couple seconds. The refresh rate is exactly the same on both monitors, its set to 60Hz. I have no idea why this is happening!

PC Specs:
I5 6600K
Gtx 1060 6gb
Gigabyte Z170 Gaming K3

Thanks for the help!

does the tearing happens on both monitors, or only on one of them?

Have you tried connecting with both hdmi and dvi?

My monitors are both connected to a HDMI, then one of the HDMI is plugged into the GPU, and the other goes into a HDMI to DP adaptor then into my GPU, the screen tearing only happens on the monitor that is going through the adaptor. My GPU only has 1 HDMI port and one DP port, so that is why I need the adaptor. It also has a DVI port, but I tend to leave that one alone XD.

if you run each monitor on their own via hmdi without an adapter, do they both display fine with no tearing?

No problems when I do that...

ok, so if you use the DP adapter on the monitor that's usually just straight hdmi, does the problem move to which ever monitor is using the adapter?

No, the problem doesn't occur when I try that...

ok, if you reconnect everything back the way it was, has the problem suddenly fixed itself or does it still have the issue?

It still has the issue ;/

ok, so current scenarios are:
1. monitor 1 with hdmi & monitor 2 with hdmi/dp = tearing
2. monitor 1 with hdmi/dp & monitor 2 with hdmi = no tearing

correct?

If so, just run with scenario 2?

Nope. The one thats plugged into the DP adaptor always has the screen tearing, it just swaps the monitor with screen tearing...
Thanks though :/

have you tried swapping over the hdmi cables?

ie. the cable that was just straight hdmi originally, use the adapter on that one, hook both monitors back up

same problem?

No difference....

hmmm seeing as the problem is following whatever the DP adapter is connected to, I'm wondering if it's the adapter that is causing the issue?

what model/brand is it?

The Brand is RANKIE, heres the amazon link: https://www.amazon.co.uk/Rankie-Plated-DisplayPort-Adapter-Converter/dp/B010SDZZ80/ref=sr_1_2?s=electronics&ie=UTF8&qid=1503579599&sr=1-2&keywords=Rankie+DP+to+HDMI

hmmm can't see any reports of that type of issue when using that specific adapter and it seems to get decent reviews

if it's not that, then it could be a bad DP connection on the GPU, but you'd need a DP capable monitor to test that (ie. connect DP without an adapter)

Just in case, do a DDU driver wipe and re-install latest drivers

alternatively, you could get a dual link dvi cable instead

btw, which version of windows are you running?

I don't really want to buy a DP cable, but if there is no other fix I will, and I'm running windows 10. I'm a good 51% sure its to do with my PC not the connection or monitors, don't ask why, because I don't know XD

i'd definitely go with a DDU wipe and re-install of the nvidia drivers, just in case. Won't do any harm

if still the same after that, is the tearing just vertical or also horizontal as well?

I've reinstalled the drivers via device manager, and the tearing keeps happening, the tearing is Horizontal and Vertical, it also blacks out every 10 seconds or so for 5 seconds. I recorded the screen using Shadowplay, and the screen tearing did not show on that, which means its not from the computer as it would of caught it... Am i right in saying that?

ok, if it's vertical and horizontal and blacking out every so often, then it's starting to sound like a bad connection somewhere

we know the monitors are ok as the problem is following the DP adapter connection

so, it's sounding like it's either a bad port on the GPU, or possibly a bad DP adapter

Thank you, I'm getting a new GPU tomorrow, and ill order a new DP adaptor, so should be good!
