Good luck :)

Thank you!

Are you using an adapter or do your monitors have native DP?

Apple mini-DP to DVI dual link, it is the only one actually available in NZ... and the 5970 is mini-DP anyway.

It is temperamental but a pulling out of the USB and plugging it back in sorts my probs (like that mon being stuck at 1600x1200, the 2 others being proper 1920x1200)

I went ahead and ordered 3 dell 24" monitors with DP. I would rather have something future proof and guaranteed to work.

And if DP gets scrapped for the next 'shiny new spec'?

This is still happening :(

*See sig for specs*

I will let you know what happens next...I just swapped out cables and put the eyefinity monitor in the middle vs far left.

Swapping is a good idea.

BTW you (very accurate) sig needs to be changed. You need to keep it simple on this site

Use this block of text to display your system specs. There is a 512 character limit. Please no images.

Please keep the text (colored text is fine) between sizes 9 and 11 (using BB Code). Run your specs horizontally (rather than vertically), and limit to four lines at normal forum width.

It takes a bit of work to fit it all in LOL

*lol* Sorry man...Ill update it soon

OK, I've tested this for two days now and at least for me it works.

A few days ago I added the "HypraVision" app for CCC. After being up for 3 hour with all the monitors running the flickering has stopped and I was able to play all my games with out any problems. I though whoa it working now. :P

Well I turned the rig on today and waited to see if the flickering came back and it did so I did the same thing and kept all three monitors up despite the flickering on the DP screen. Sure enough a few hour later the flickering was gone. I don't think The addition of the HypraVision app did anything but you can try it.

And if DP gets scrapped for the next 'shiny new spec'?

Then I still have HDMI, DVI, and VGA ports.

I will cross that bridge when I get to it. Thanks to ebay, these new monitors are going to cost me nothing additional out of pocket.

FWIW I also started to get this happening with my setup occasionally and I am using a DisplayAdaptor -> VGA adaptor.

Usually I need to unpug the adaptor and the plug it in again for the monitor to start showing something, but sometimes even that doesnt work and I need to reboot, and then unplug/plugin.

I think it is a driver issue as I can go for ages without it happening. But very odd. as it only started happening in the last few days, and nothing on my system has changed.

Hey guys,

One problem I am having with the Dell monitor sometimes is that it doesn't refresh and loses signal to the display port. As in sometimes when you open a game the screen goes black for a second before the game loads, well the 2 side monitors load and the dell just sits their then says no signal = eyefinity fails due to loss of the display port.

I can't play dirt 2 because of this :(

I have noticed that the Dell takes about 3 seconds to change res etc and UAC in Windows where as my 2 BenQ side monitors take about 1 second. Is this due to monitor firmware or something?

Anyway around it? It's not happened much and usually does it on odd occasions but with the Dirt 2 demo it won't load the resolution without timing out and saying no signal making me turn the monitor off and back on again to fix it.

Which dell monitor is this? Are you using any sort of adapter?

Nope straight into the display port. It's a Dell P2210H 21.5".

It just seems to be the Dell Monitor is much slower at coming back on/off compared to my Ben Q or any other monitor I've had. UAC in Windows can take a good few seconds to pop up after the black screen and the same when loading a game. So I'm guessing my other 2 monitors are ready to go and waiting on the Dell at which point the graphics card/Windows might of thought it has timed out?

I'm not a 100% all too complicated for me hehe. Dirt 2 did manage to load once out of the 6 times I tired :P

So far so good...

I basically changed it from my 3rd monitor to my middle monitor (which just so happens to run the important stuff e.g. Start/Taskbar yadda yadda

I am having the *exact* same issue with regard to the monitor randomly blanking out which is attached to the displayport-to-dvi active adapter.

I'm also using the adapter from Dell (that cost over $100 and is now useful only as a paperweight).

It does not appear that there is a fix yet. Is that correct? It definitely seems to be something related to the OS sending a "sleep" or "inactive" signal to the Displayport-connected monitor. I'd be curious to see if a native DP monitor would have the same blanking issues.

In any case, I'm extremely disappointed. I was really hoping to replace my TH2go with something more widely-supported. Instead, it looks like I've become a beta tester for yet another flaky PC hack :-(

For those that feel comfortable flashing their BIOS (note: may void warranty) and they are seeing DP issues on their HD 5870 could I ask that you try out the following BIOS:

Thanks Dave, I'm welling to give it a go but can you help me with a link on flashing the newer cards. I haven't flashed a GPU in a long time, thing may have changed a bit.

Thanks in advance. :wink:

Wow. I'd be very concerned with possibly bricking my brand new 5870 (although I do have 2 - still) via BIOS flash.

Does ATI have a tool like NiBitor (which I've used to flash Nvidia cards)?

And, while I am incredibly appreciative of the effort, I do feel as though I'm being asked to beta (or even alpha, since we're talking BIOS here) test ATI's hardware for them. This Eyefinity feature is being touted very highly for something which is this buggy. I certainly wish ATI luck with it, and I'm willing to help in any way possible.

But I can't help but be a little disappointed. :(

Does anyone know if there have been blanking problems with just using a native DP monitor? I'm seriously thinking about forgetting about the DP-->DVI adapter and just getting a nice 24" HP with native DP connection.

I'm at a point in my life where $ isn't a big concern - but the time spent troubleshooting this crap is. So, anyone know if this would be a trouble-free way to go?
