Dual Display and TDR. Questions??? As far a dual displays go we have quite a number of users (including me) running 2 displays and getting TDRs for no obvious reason. Disabling 1 display seems to cure or at least reduce the rate of TDR occurance considerably such as to take weeks of run time to be sure the TDRs have stopped. Earlier in the thread someone (Sorry if I could find the comment I would credit the member) mentioned they continued using 2 displays and when the TDRS started if they disconnected 1 display the system would recover and stabalize. I have tried disconnecting the DVI panel myself and indeed the "Infinite loop of TDRS" does stop almost immediately. (I am currently running in that scenario as I feel sure the a system restart will clear things for a while.) If I reconnect the DVI I will immediately start with the TDRs again. And it appears the DWM and the ATI External Event utility (HOTPLUG detection) are battleing for CPU time. Other members in the thread got me thinking about AERO, the DWM and the ATIEEU. And what the heck is the M$ thing called TMM? (Transient Multimonitor Manager) In any case I would like to ask other to try the test and see how consitant the outcome is. Or is this just another random occurance that some see and not others. So for those who - have multi displays - see multiple consecutive TDRs What happens when you disconnect a display asap after the TDRs start? - Do the TDRS STOP? - Does reconnecting the display trigger more TDRS?
