These things are giving me all kinds of grief.? They just stop working.? I had one job with 3 rooms....all 3 rooms stopped working on the same day after about 5 or 6 weeks of working fine.? These are all with planar displays.?? I have other jobs with samsung displays and same thing -? the driver just stops working until i reboot the processor.? I tried reloading the driver at regular intervals and a few other things to try to keep it alive but i am about to give up on certified drivers altogether.
