I work in an enterprise environment where we have many of these monitors in 4 monitor configurations running on Dell 7010 desktops with Radeon 7000 graphics cards.
In this environment several users, utilize these pc's and configurations, and there are many issues on "all" of the machines where one monitor won't come back up, fails, etc... The users will log in, the monitor will work, and just shut off. OR they will lock their profile, come back, and it's off. It's generally the same monitor.
We have swapped out cables.
We have swapped out monitors.
We have swapped out video cards.
We have turned all the pc options to high performance.
We have put APC's on them and off of them just to make sure they were getting consistent power.
New and old catalyst drivers.
New daisy chain cables.
Used various DisplayPort 1.2 options on the monitor themselves.
Dell actually had to replace these with Revision 03, and the monitors still fail.
I looked on the AMD site and noticed that for me to use the DVI side (because these monitors don't have DVI on them) that I would need a DVI cable to display port that is "ACTIVE". However all of the cables I have found are DisplayPort to DVI (one way) cables. Which means of course, that they will not go from the DVI port on the video card to DisplayPort. We tried one that was offered by AMD and it does not work.
Does anyone else have any other ideas? OR know if there is a DVI to DisplayPort adapter/cables that ARE ACTIVE? Again, DisplayPort to DVI will NOT work.
Trying to find another idea before we get rid of all of our dell equipment.
Thanks
