DisplayPort flicker on monitors - Page 4

post #31 of 40
I have the same flickering on my DP monitor. It only happens if I try to have a full screen app running for the first 5-10 minutes after starting/resume from sleep. Desktop is fine unless I fullscreen a folder. Runs perfectly al other times.

Only happens when I am running DP as the connectivity of the monitor. Cable maybe?

Win7 x64
ASUS 6950 DirectCU II

#1 DP - Dell 2412M
#2, DVI - Benq 24"

I threw mine all on DVI using adapters, no more flickering smile.gif

Using this one: http://www.amazon.com/gp/redirect.html?ie=UTF8&linkCode=ur2&camp=1789&creative=9325&tag=overclockdotnet-20&location=http%3A%2F%2Fwww.amazon.com%2Fgp%2Fredirect.html%3Fie%3DUTF8%26linkCode%3Dur2%26camp%3D1789%26creative%3D9325%26tag%3Doverclockdotnet-20%26location%3Dhttp%253A%252F%252Fwww.amazon.com%252FAccell-B087B-006B-DisplayPort-Single-Link-Certified%252Fdp%252FB004071ZXA%252Fref%253Dsr_1_4%253Fs%253Delectronics%2526ie%253DUTF8%2526qid%253D1325586177%2526sr%253D1-4

You also have the same Dell as me... maybe its an issue with that. Who knows, but after using these adapters its perfect smile.gif

K... So i've got my annoying Screen Tearing "line" as well.... yet...

I'm using:

DVI
Mini-DP > Mini-DP to DP > Dell Active DP to DVI (this is powered by USB)
Mini-DP > Sapphire Active Mini-DP to DVI (came with my Sapphire 7970)

BUT. But but but MY DVI monitor is the one that has the screen tearing "line"...!

What the heck? D:

Would me replacing my dell usb active adapter with a normal active adapter get rid of the tearing line?
I'm looking at this adapter ($19 with free shipping. And yes, it's active.) :

The line has nothing to do with this issue unfortunately. Enabling vsync in games usually gets rid of it.

Unless you get it on the desktop or something.

Don't have experience with the Dell Dual Link Active Adapter but if you want to try get this one validated for Eyefinity.

I have 3 monitors with DVI/DP connections. Currently, I have two hooked up DVI > DVI and one DP > DP. The one with the DP connection has a constant tear that is visible at all times. This includes not only during full screen videos and games but also on the desktop such as when I move a window across the screen.

Based on what I gather from reading this thread, replacing the DP > DP connection with DP > DP to DVI should eliminate the tearing problem. Is that correct?

If what I describe as "flickering" is the same as the tearing that's being experienced here, then the DP to DVI adapters will sort it out smile.gif the Accell one linked to by Ken and myself work perfectly... try to get EyeFinity certified ones... I tried a non-certified one and it eliminated the issue, but sometimes the display would fail to register.

I finally fixed my screen tearing issue. It isn't an option for everyone, but it works for those that have three DisplayPorts or three mini DisplayPorts. I had to buy three active DisplayPort adapters and run all three monitors on the displayPorts (didn't use DVI at all). Since the monitors are all running off the same adapters connected to the same ports, there is no sync issues.

I have the 7970 DC2T shown here:

I used these adapters:

For 3 screens, if you're needing a Display Port to DVi adaptor, you'll need an Active one. Not the cheap 10 to 20 bucks adaptors.

Here's the Active Display Port to DVi adaptor I'm using, it's the best deal right now for an actual real Active adaptor. I searched everywhere. Only other models I found that perform the same function and quality as this where 50 USD. This one only set me back $25.99 USD plus a 5 USD packing fee.

http://chinacheapbuy.com/index.php?main_pa...;products_id=69

I also found the same model on Ebay, which maybe from the same source, price is nearly the same.

http://rover.ebay.com/rover/0/e11030.m43.l...AEF%3AGB%3A1123

The adaptor has an IC circuit for this function that is a new chip and design purposely suited for this, so the performance is A1 and it makes all those other really high priced units obsolete. Forget about trying to use those cables from Amazon for 10 to 20 bucks they can't handle this task.

Hi,

I'm having a very similar issue. From a thread I started here in the AMD ATI section:

"
Lately since upgrading from 12.3 I've had flickering on the DP connected screen and was wondering if I have a bad displayport adapter. Turning on Vsync or rolling back to previous driver fixes problem. I think my DP adapter is by Powercolor or Saphire. Anyone recommend a better DP adapter if that is the case?

Thank you.

System specs:
Evga Classified X58
XFX 6970 Trifire in Eyefinity running three Samsung PX2370s. (DVI-DVI, DVI-DVI, DP - Act Adapter - DVI)
SSD and raid array
SB Titanium
1200 watt psu "

So I think I'm going to try the Accel adapter. Think is vsync fixes the problem and at 5670x1080 resolution 60fps is fine unless I'm benching.

Just afraid to waste $35 and see that it doesn't work. And if it doesn't 100 percent can tell you no more ATI/AMD for my graphic needs!
