Displayport entering power save mode problem

[bgt]

Some monitors, like my HPs have an option to maintain the DP connection even in powersave mode. Fixed my issues. Check your monitors menu settings.

Cannot find this option in my Dells U2412M?

FWIW, that Accell cable did nothing for this issue with my 7970s and Auria EQ276W monitor.

I'll have to check that. I don't know if the U2713HMs have that setting or not.

That sucks, but it's also good to know. This is clearly a widespread problem as there are many posts on various forums. It's unfortunate that the industry hasn't given any answers for it.

FWIW before I discovered the power save option in the menu, I could get my monitors to reconnect by hitting ctrl alt del.

FWIW, I had this same problem which I ultimately solved by replacing the DP cables. The full story is superuser.com question 639191. Here is the link:

since were nearing the quasi necro range for unresolved threads, i'll throw my 2cents.

i've had no problem with single monitor DP sleep or idle power down timer. i do remember some issues with dp and dvi recognition being solved by a reboot or two until windows recognized that a new monitor was involved and worked out EDID.

for the OP's situation i would recommend going into catalyst and making sure:
-the largest res panel is set to primary display and
-the problematic dp cable is on the video card port closest to the motherboard.

i have a eyefinity6 and when setting up i made sure to populate the mini-dp ports nearest the pcie slot. when setting up triple monitor dp, everything worked no hassle. later on when i rearranged my desk and pc's the cable lengths forced me to run a dp/dvi mix and it was less than ideal when it came to setting things up.
