How to I flip my screen both Horizontally and Vertically

> how do you do it

I am using UltraMon : https://www.realtimesoft.com/ultramon/

I have a laptop + 2 monitors + the monitor on the teleprompter. I mirror one monitor to the teleprompter monitor.

In mirroring > settings, select 'one or more monitors' and apply settings such as the ones below.

You can tick both V and H flip. Here I selected only H flip, because the V flip is already selected in Windows display settings. UltraMon does the mirroring at the software level, not hardware level as in Windows : that implies some CPU load, but all this works well in a video conference. The only thing I would have done differently is the size of the teleprompter : the bigger the better.

Hi franklyray

That is exactly what I am doing and for the same purpose: better eye contact.

See the image below. At the bottom : my laptop, at the top : 'a monitor below a mirror' where the display mirrors the laptop's display, with an H&V flip.

I am having the same problem and banging my head against a wall to get an answer. I think it has to do with manipulating the windows shell with DM_DISPLAYFIXEDOUTPUT but not sure how to utilize it. I'm coming from Linux and xrandr always solved my problem there but nothing in Windows. If you find an answer let me know.

I have the same problem -- I need to have one of my monitors reverse/mirror/reflect the image for a prompter mirror system to achieve eye contact video conferencing.  People get confused when discussing this because Microsoft and graphics card manufacturers often mistakenly use the term "mirror" when actually they mean "duplicate" a screen.  Mirror is used here in its literal sense -- reflected image such as from a mirror.  When one is using a reflected image in a prompter system one needs the display actually mirrored or reversed so the reflected image is normal and readable.  I hope Microsoft will add these capabilities to their operating system.

In the meantime, I'm using UltraMon to get by.  It's not ideal because it cannot make a monitor mirrored unless one has a separate monitor to mirror from.  Like most people, my main computer screen is large and I want to be able to use it during a video conference to display other things -- not just a participants image.  Using three screens as a previous responder above gets around this. 

I'd like a two screen option where one small monitor is always mirrored for the teleprompter and is an extended display (not duplicate) one can use even when not on a video conference without removing the monitor from the prompter assembly.

Part of my workaround with UltraMon, with my two screens implementation, is that UltraMon can mirror to the second display a portion (user selectable) of the main screen's display.  This allows one to still use their main screen to display other things during the conference though some is lost for the video conference participant display.  It's a compromise.

Microsoft, please add the capability for true mirroring (not duplicating) of monitors to support prompter mirror use of secondary monitors for better eye contact video conferencing.

Thanks!

Did you ever get this to work? I have the same problem with my teleprompter.

Thanks,
