I have a 32:9 monitor which I've split into 2x 16:9 however when I go to share in Teams or WebEx it sees the entire 32:9 monitor to share, whereas i only want to share one of the 16:9. Is this possible? (this was the only reason I bought this software).

It can't fake WebEx into seeing the splits, but this may work:

  • On the Settings > Functions tab, assign a key combination to the "Mirror Selected Area" function
  • Run that function and select the split area that you want to mirror
  • A new window will open with the mirror contents, and you should be able to share that window using WebEx

Hope that helps!

That's unfortunate. That workaround works in theory but the mirror runs ~1 frame per second (on on i7-7700k and GTX 1080 TI).

If you like, you can set the "Mirror Polling Interval (ms)" setting in the Advanced Settings to something lower to speed it up. You can set it as low as 1, but note that the lower the value, the more CPU it will use.

Thanks!

I cannot find information about the Mirroring capability. Where is this documented? How do I enable it? I have the same use case -- to share a portion of my ultra-wide monitor on Teams

Hi Peter,

The steps that Keith outlined above should work for you, have you tried them out?

Thanks!

I tried it, but the screen goes mostly black with a lot of red lines. Kind of hard to explain :-)
For a second, it flashes what I think I'm supposed to see, but I think there's some sort of scaling issue.

I'm still interested on where the documentation is for the mirroring. For example, what do all these options mean (see attached)

Hi Peter,

Could you send me over a video of the flashing happening?

For the functions, we don't have specific documentation on what every function does. Those mirror functions will mirror the specified monitor into a window. The border/no border just adds or removes a titlebar to the mirrored window.

The "With splits" function will allow you to mirror just the your monitor split, rather then the entire monitor. The "Selected Area" will allow you to select a certain section of your monitor to mirror. The "Window" function will mirror only the specified window.

Hope that clears things up!

Here you go. My file is too big to attach, but here's a link: https://www.dropbox.com/s/b6xqpbgoxw6hj1j/2020-12-17%2012.43.24.mp4?dl=0

Hi Peter,

It looks like your mirroring the box that's already getting mirrored, and it's creating a loop. If you move the window at the top away from the red box in the middle, it should prevent that.

Thanks!

Thanks. Figured it out. It is very non-intuitive. It seems that the mirror it creates is the full size of my screen, with black bars around the area it's mirroring. So I moved it aside, to stop the recursion, and then I had to manually change the size. Is this how it's supposed to work? It would make sense to make the mirror the same size are the area it's mirroring. It would also make sense to not have the mirror overlay the mirrored area when it first starts, leading to the problem I had. It should create the mirror in another location on the screen.

Also, what is the default polling interval. What is a good setting to make it a little faster?

thanks

Hi Peter,

The mirror selection will be whatever sized coordinates you set from the beginning, as well as whatever location you've set. The mirrored window just opens full screen on your primary monitor by default.

The default polling interval is 350ms, but it can be adjusted in the advanced settings.

Thanks!

Not sure what you mean by the location. I select the top-left and bottom-right of the area I want to mirror. How do I determine the location of where the mirroring will take place?
You say that the mirrored window opens full screen by default. How do I change the default? Since I just have a single monitor that's 49" across, it makes no sense to open full-screen on my one and only monitor

When setting the polling interval, are the units always in milliseconds?

I would recommend creating a Trigger rule to have it place the mirror output window in the spot that you'd like it to be. I've attached a screenshot example for reference.

Hope that helps!

One more issue about mirroring. If I am sharing my Mirrored area (with Teams, for example), if another window goes over it, the user sees a big gray blob blocking it. If they are only seeing that one Window, why would other windows be able to block it? Is there any way to prevent that?
The problem is that I'm looking at another part of the screen, and I'm not really paying attention to the part that is being shared, so it keeps happening without me realizing it.

Does that happen only with Teams, or are you able to reproduce that same behaviour with other windows as well?

Ok, I'll do some testing with Teams next week and see what I can find out.

Thanks!

Sorry for the delay on this, finally had a chance to test it out. I wasn't able to reproduce the issue here though. You're using the "Mirror Selected Area" function? Or "Mirror Window"?

I think I'm using "Mirror Selected Area". What's the difference?
Jan 9, 2021  • #22

Not sure if there is one but I wanted to test the same way you were. I tested with "Mirror Window" and "Mirror Selected Area" and both worked fine for me. I'll do some more testing to see if I'm just missing something here.

Thank you! Yes, I've done the same you think have. I move the mirror out of the way so I can work while someone else can see my screen. But I have to be careful not to cover the mirror window

@x3s: Thanks for posting that link, I remember that thread now, I was never able to reproduce this issue and still can't

Does it matter which application you put in front of the window that's being mirrored?

From my recollection it did not matter what application was in front.

If you share a different window with Teams (e.g. share out Chrome or something) and then move a Notepad window in front of that Chrome window, does the same issue occur?
