Eyefinity third monitor screen tear

post #1 of 11
Thread Starter 
I am having issues with the third monitor screen tearing. The first two monitors are using display port cables and the third one with issues is using some HDMI into the monitor with DVI on the other end to conmnect to the GPU. That was insluded with the monitor. It always tears in the same exact spot on the screen in multiple games when it does it.

It is slower to display afteer starting my system or exiting full screen applications. About 3 seconds slower than the display port connected monitors.

Would that cause the screen tearing problem? I ordered a third display port cable to plug into my second 7970 and hopefully that fixes it. If not would this be the monitor itself causing this tearing?

Nobody knows?

Hi Shaded War, does it still happen with the third monitor when connected to the graphics card without the adapter? Try another adapter or output to see if this is the case.

I'm not using any adapters, it is what is supplied by Asus with the monitor. On one end it is a HDMI male connector that goes into the monitor, and the other end is a female DVI single link that goes into the GPU.

It looked a bit weird to me to do it that way, which is why I am thinking that may be the cause of the tearing. The monitor treats it as a HDMI input because of it. Theres no real DVI input on the monitor connections.

I will try connecting it with my display port cable to my third monitor and use the Asus DVI cable on my second monitor to see if that fixes it.

I can confirm this issue is with the strange cable that Asus included with the monitors. My second (middle) screen is now tearing and my third monitor is perfect with the display port cable.

I should be recieving my third display port cable tomorrow and hopefully theres no issues with having my display driven by my second 7970. Theres only 2 display port connectors on each 7970. Any problems with doing this? I know Nvidia used to require it for surround.

Probably the adapter is not good. You cant connect the 3rd display to your second card. All the cables to one card.

Oh well that kind of sucks. Why wouldent they add a third display port to the 7970? It seems far superrior to anything else I have used. I will try using just a plain HDMI cable then since I have one laying on my table.

Ok now the one using a plain HDMI cable is tearing. What a mess this is why cant AMD just have 3 display ports on their GPUs, especially higher end ones. It seems the Display port connected ones have way less response time causing the other one to tear. I will have to dust off my DVI to VGA adapter and see if that tears since these monitors dont have true DVI.

I use 2 dp and one hdmi to dvi and i dont have tearing.Its limitation for amd cards that they dont have 3 dp ports.The tearing is caused because dp use different clock generators than dvi
