Displayfusion unable to switch to a specific monitor profile

Hi,

I’ve recently changed one of my monitors and updated the graphic card drivers and since then display fusion seems to be unable to switch to a specific monitor profile. If recreated the affected monitor profile (‘tv’) in version 9.7.12 and 9.8b12. In both version the effect is the same.

Once I try to switch to the ‘tv’ profile the current monitor setup is not modified. It seems that DisplayFusion is hanging or blocked (running at around 12-14% CPU load which would be one virtual core). Only the only way to access display fusion again is to kill the not responding process.

Previously everything word fine. The only thing that changes was the following:
- Switched one of the monitors
- Since I also need to use the 24’’ monitor for other laptops and lack of usable input/output interfaces, the monitor is not directly connected via dvi but dvi -> hdmi switch -> dvi. However, this does not seem to have an effect regarding display fusion.
- Updated to the latest driver of the graphic card
I’ve attached to log output for versions 9.7.12 as well as 9.8 beta 12.

Hello,

What monitor did you upgrade from, that used to work with the profile?

Thanks!

Previously the profile used to work. However, that was some time ago and I did not use the profile for some weeks. Since then, I changed the monitor setup and had some issues with the previous graphic card driver (VLC crashed sometimes if hw-acceleration was enabled), I upgraded the driver as well and created a new profile replacing the old one.

Recreating the 'tv' profile using the usual windows tools is working for the display part without problems. There is only one additional issue that cloning the desktop does seem have an effect that the hdmi audio output device is lost, but that seems to be a windows/driver issue and I will check that sometime later.

Reapplying the stored 'tv' setup with DisplayFusion has the described effect of a frozen DisplayFusion and no monitor setup changes.

Hello,

Strange, it looks like DisplayFusion is getting caught in a loop trying to apply that profile. I've added this to our list to look into, and noted down your contact information, so we'll be sure to let you know if we have any further information on it.

Thanks!

One short update. I’ve recently switched to the current release version 9.8 of DisplayFusion and did a clean reinstall of the AMD graphic drivers. This solved the HDMI issues, but the DisplayFusion issue is still present.

Switching from the ‘default’ to the ‘tv’ profile is not possible and DisplayFusion is probably hanging in an endless loop. However, I accidentally discovered one workaround for the issue. I’ve another profile ‘work’ which is switching my setup with the LG monitor as primary and Eizo as secondary (extended) monitor to using the Eizo monitor as only active monitor. If I’ve switched from 'default' to the 'work' profile and then switch to the ‘tv’ profile (adding the Samsung tv as output, change the resolution to enable cloning of the monitor), the ‘tv’ profile is working. I’ve tried it a couple of times and so far, there has not been any problem.

In short
  • default -> tv ==> will not work
  • default -> work -> tv ==> is working

Switch directly back from ‘tv’ to ‘work’ or ‘default’ does not have any problems at all.

It seems that there is some kind of ordering required for the changes needed to update the monitor setup. In case of switch from ‘default’ to ‘tv’ profile, this is not handled properly by DisplayFusion.
