Eyefinity, HDCP, and Blu-Ray

post #1 of 5
Thread Starter 
So I have an issue and I am wondering if anyone knows a workaround. I tried google but there is too many irrelivant posts that come up.

So If I try to watch a movie at 5760x1080 a message comes up that I need to update my Display driver. Which is not the case as I use the latest.

Now If I disable Eyefinity and go to 3 Screen Duplicate and set it to 1080P HDTV It will play Blu-Ray just fine. Without the warning.

Now I have seen some HDTV support options in CCC but I can't seem to get movies to play when I do 5870x1080. Even if the movie only played on the center screen i would be fine with that. Its just annoying switch to back and forth.

I also have another issue where sometime my middle monitor which is connected via a Accell Gold rated DVI->DP active adapter goes blank and puts the monitor into Powersave mode. It usually happens when I alt-tab or enter/exit a game. I have to unplug the adapter and plug it back in so it wakes up. All sleep modes are disabled so its not that.

You have asked 2 questions.

Response 1
AFAIK, Windows just sees the three monitors as one giant monitor of 5760x1080 when Eyefinity is enabled. For gaming, this poses no problem as the gaming code supports such a resolution. But when playing back/watching a 1080p movie, I do not think the Blu-ray playing software supports playing the movie at such resolution. Therefore, it does not work when Eyefinity is enabled. In other words, the software just cannot play the 1920x1080 movie on the middle one-third section of a giant monitor of 5760x1080.

Besides Alt-tabbing, does it happen in other times?

Alt-tabbing has its own problem, regardless if it is used in conjunction with Eyefinity or not. I think it has more to do with the gaming code, which obviously varies from game to game. Some games are more alt-tabbing friendly than others. Eg some games need you to actually have another Opened Window on the Desktop before it can switch to that.

Additionally, it is not uncommon for the monitor (connected DP) to have this black/blank problem while the 2 other monitors (connected with DVI) do not have. Try these diagnostic steps in order:

1. Update all drivers with Windows Update (Windows should be able to update the .inf file of your LG Flatron IPS 226V. This is important as this monitor was only released last December and so it is so new that it might not be properly detected)

2. Use latest AMD CCC

3. As the 3 monitors are identical, do this step to eliminate the possibility of a faulty centre monitor.
Just switch the cabling of the centre monitor with either the left (or right) monitor. And now see if the blackout comes to the left monitor. If yes, then it is very likely that monitor is faulty. If the blackout still comes to the centre monitor, this rules out a faulty monitor.

4. As the 2 HD5870s are also identical, you can do similar testing to check possibility of a faulty output port of a card.

5. Use another quality cable for connection to the centre DP monitor...if fails, try a third one.
The cable ought to be as short as possible...no longer than 6' or 2m.


I hope these steps help you to solve your problem.

Yeah I have already tried a new DVI cable, I haven't tried switching cables between monitors so I will try that next. All drivers are updated as of Yesterday.
It didn't happen in Vista 64 Home Premium, only when I installed a fresh copy of Windows 7 Ultimate 64 bit edition along with a new SSD. So I could use the 11.4 drivers, but the problem happens with 11.2 as well.

I am using 1 JVC 1.4 HDMI cable, 1 DVI->DP Accell active adapter gold certified, and a Elecomm DVI cable rated for 1920x1200.

If you are quite certain that it did not happen in Vista 64 HP and the problem only began to show up after a fresh install of Windows 7 Ultimate 64 bit (w/ SSD), then it is almost certain that it is not hardware related. But do test those hardwares anyway, for the peace of mind.

So, use Windows Update to update first. You might have to do this several times because, for some unknown reasons, it sometimes just does not download all updates in one go (kind of strange).

And, try a few most recent CCC then.

Yeah Vista gave Zero issues. It worked like a champ. My Sandy bridge system is down for the count on account of the recall so I used my Windows 7 Ultimate so I could use 11.4 drivers and play Dragon Age 2 with better frame rates. This is when the problem began showing up.
