I'm trying to figure this out but so far I'm not getting it right. Before buying DisplayFusion I inquired as to whether this was possible and was pointed to Triggers. Hoping someone who is experienced with that DF feature can help, please.

Sometimes I open a PDF from within Acrobat (Ctrl+O) and sometimes I double-click a PDF in its location. The first PDF I open launches Acrobat if its not already running, and that occurs on my far left monitor where I want it. I think that is a remembered position (OS or Acrobat, I'm not sure). However, when I open subsequent PDFs (Ctrl-O or double-click) they open on my middle monitor and then I have to drag them off to the left. I'm tired of doing this. I need PDFs to always open on the same monitor (my far left monitor). This worked on my Windows 7 machine (not sure if the OS handled it, or it was DF or Ultramon at that time).

I don't really understand DF Triggers so this might be easier than I feel like it is when I try it. I humbly ask for some help from the community. Thanks!

Sorry Keith, just saw your reply now. I deleted the two things I had tried and now I don't remember how I set them up to reproduce for you. Honestly, I'm overwhelmed with all of the potential functionality of triggers and just am not sure where to start. I will try again now and see if I can produce something to show you (or better yet, get it to work). The bottom line is that I just want PDFs to always open on a specific monitor. I'll reply again in a bit. Thank you for your response.

OK, here is what I think I did before and as I was trying now it was still what I would come up with. I've probably over-simplified it. I have read some of the documentation that describes the various Trigger fields/options but it's a lot of info and I don't really know what I'm looking for (what is applicable to my needs) so I get lost. Maybe you can point me in the right direction. Thanks for any advice.

I actually use Adobe Acrobat, not Reader. But I think I've gotten it to work. I tried it a few times double-clicking PDFs in various locations and using Ctrl-O in the Acrobat application window and so far, the PDFs open on the middle/main monitor but instantly are moved to the far left monitor. It's a bit visually funky but it's certainly a huge step up from the way it was behaving.

I attached a screen shot of my working Trigger. I appreciate the help. I actually found an old thread that you posted suggestions on and that led me to add the asterisk (*) to my .exe file in the Trigger and that seemed to be the key. Thanks!
