MS Windows Updated to 1709 (Build 16299.309) as of 27th March 2018. Latest AMD Driver as of 27th March 2018 (V.18.Q1.1). Still current. Running Watchout 6.2.2. Previously running 6.2.1 6x mDP to HDMI adaptors (Startech) to 1080P monitors running at 60Hz. Forced EDID has been used. Issue: When attempting to start using Watchpoint.exe on display systems, it will attempt to load and then fail, which will then restart via the watchdog and continue to go through the cycle but fail to start. When running WP.exe, this will take around 18 seconds to start but will actually start. Adding GPU scaling to each screen via Radeon Pro settings cuts load time to around 12 seconds and after 4 cycles through the watchdog, will then start the show when run via Watchpoint. When running 4 outputs, the screens seem to initialise quick enough under Watchpoint without causing the watchdog to kick in and restart the programme, but as soon as we go to 5 or 6 outputs, the time taken to initialise is too long and therefore, can cause the watchdog to restart the programme. This is happening on multiple systems of identical specification. The start-up is consistent and repeatable, as well as being identical between the two systems making a hardware fault very unlikely. Additionally, using different screen edids appear to impact the initialisation time, one edid with very flexible settings ( lots of colour depths, resolutions and refresh rates available ) took almost 45 seconds to initialise running WP.exe, subsequently putting watchpoint.exe into a restart loop. We also tried the gaming driver variant which is available to the WX9100 and this made little to no difference to the initialisation times for WP.exe. We found a forum post indicating that the TdrDelay and TdrDdiDelay registry entries be increased to prevent Windows from killing the graphics drivers too soon. However these registry entries were not present to edit, and adding them had no effect. This has also been seen on multiple other systems running more than 4 outputs at any one time and also on systems running W600 GPU, both at 1080 and 4K. Is there any way to resolve this and if not, is there something that can be done to extend the timeout of the watchdog so that everything has time to initialise?
