    "DisplayPort connection problem" with FirePro W2100

    chrullrich

      I just installed a FirePro W2100 to use with my LG 34UC97 (3440x1440) monitor, and just about every time the system wakes up from sleep, it tells me that there has been a problem with the DisplayPort connection that "prevents me from using the highest resolutions and/or refresh rates". The display runs at 30 Hz after that, instead of 60. I can force it back to 60 with little effort through the control center.

       

      The monitor is DisplayPort 1.1 by default and can be set to 1.2; I tried both modes with the same results. Using the on-board Intel HD Graphics 530, via the same DisplayPort cable, there have never been any issues (at least of this kind, hence the FirePro).

       

      According to its specs, the W2100 can run 3840x2160 at 60 Hz, so why should it have a problem with 3440x1440?

       

      Thanks,

          What DP cable are you using and how long is it? What driver version are you using?

              The cable that came with the monitor; approximately 1.5 meters, and while I cannot remember exactly where, I know that some utility told me about it having four lanes.

               

              Driver version was 15.301.2001-160202a-299314C-Retail, and the control center did not detect available updates, but I just checked by hand and lo, there is a newer one. With "15.301.2601-160416a-302423C-Retail_End_User" a quick test has not reproduced the issue.

               

              Strangely, the 2601 installer I downloaded five days ago is different from the current one, and where the installed version may have come from, I have no idea. Probably Windows Update at its most helpful.

                  The problem just came back. Not with a message about a DisplayPort problem as before, but the monitor simply dropped back to 30 Hz, and this time there is no UI in the driver to force it back up.
