Multi-Monitor issue with HDMI / DisplayPort

There is an issue with my dual monitor setup. My previous dual monitor setup whereas one monitor was DVI the other HDMI. I've swapped the DVI monitor with another HDMI monitor with the exception with the wire. One end has an adapter from HDMI to DisplayPort going into the graphics card; the other end going into the monitor is HDMI.

When turning on both monitors when both have been off for long period of time, all the windows on monitor which is strictly connected by HDMI move over to the other monitor with the adapter as mentioned above; as well, this has only been experienced in one program, so far. The menu bars in this one program do not work, menu bar as in your, File | Edit | etc | without restarting the program, never experienced this before with the other monitor which was replaced ?

Hi Chris,

It sounds like you're experiencing what's mentioned in this guide: https://www.displayfusion.com/Discussions/View/automatically-save-and-restore-window-positions-on-sleepresume/?ID=fa98975e-e4ed-45de-afe0-fafad56c7a83#first

What application are those menu bar issues happening with?

Thanks!

I tried what was mentioned in the guide; although it didn't work. The application which I'm having issues with is Mari a 3D program. When the monitor is off for around 5+ minutes the menu in this program is inaccessible.

Hi Chris,

After you created the triggers outlined in that guide, were the windows not moving at all when waking your computer up, or were they moving to the wrong positions?

For that Mari 3D program, if you exit DisplayFusion, does this issue still persist?

Thanks!

The issue is when both monitors are off for a long period; then turned on. The windows which should remain on Display 1 are moved to Display 2 even after they are automatically restored based on the trigger you suggested in your first reply ?

I don't know what could cause this, the previous monitor this issue never arose. I wonder if there is a sync issue between Display Port and HDMI compared to if both are the same.

Ah so the trigger is firing correctly, but the windows are still being moved after? Can you try putting in a "Wait" action in that trigger, before it moves the windows? Try something like 5000ms and see if that helps.

Thanks!

What I'd like to know is why unlike before changing one of the monitors which was DVI & HDMI, now the connections are DisplayPort & HDMI is each time I have both monitors off for long periods are all the windows being shifted from monitor 2 all to monitor 1 ?

There's an explanation at the top of the guide I sent in post #2. It's likely due to that new monitor being DisplayPort

Thanks!

I found out that as you mention it is related to the design of DisplayPort and that Display Port has an issue with; ignoring the technical term, rather; deep sleep.

I'm going to say that what Display Fusion offers is more of a hack; as Microsoft mentioned it's not a hardware issue, rather it is a Windows issue. Unfortunately, I don't know if it was ever patched outside of insiders builds which seems very foolish if it wasn't.
