I got a Sony 4k tv and a old samsung 1080p tv hook up to a splitter than to my pc so need to change between 4k and 1080p resolution. The monitor configuration only allow me to change desktop resolution not active signal resolution. The only way i can do this with nvidia control panel.

Is this something you're able to set in the Windows display properties too? This could be an nVidia-specific thing.

Would you be able to do the following to help troubleshoot this further?
  • Download this tool: https://www.binaryfortress.com/Files/DisplayFusion/BFCustomerTest.exe
  • Configure the monitor using DisplayFusion Monitor Config, then run the tool and save the output
  • Configure the monitor using the Windows settings so that the Active Signal Resolution is correct, then run the tool again and save a second copy of the output
  • Reply with both copies attached

just wanted to point out that I've got the same issue using Display Fusion 9.5 Beta 1
(previous steam downloaded version also has the same issue)

When changing resolution with DF 9.5b1, Active Resolution Signal is 4k.
Whereas with windows or Nvidia control panel it is

This issue is blocking when you need to send a FHD signal :
(HDMI cable length or target device hdmi limitation)

Thanks for your help.

Just a quick update on this, we've opened an issue on our list for forcing the active signal resolution. I'm not sure how much work it will be, but we'll definitely let you know when we have it done so that you can test it out.
