Mini Monitor Screen for Teleprompter

# _Context_

Using the iPad for Teleprompter https://github.com/dwyl/studio/issues/12#issuecomment-688843749 is _great_ for scripted content. ✅
I've recently found myself wanting to transfer a Zoom/Teams Call to the "A Camera" instead of the Web Cam and that's where the iPad is of limited use ... I cannot use "Side Car" on my Mac (Mid 2015 MacBook Pro 15" https://github.com/nelsonic/nelsonic.github.io/issues/371#issuecomment-463151626 _that I use for my "day job"_) so in order to use the iPad as a second screen I have to use Duet Display https://github.com/dwyl/remote-working/issues/32#issuecomment-489340229 which sadly is _suuuper_ laggy when it comes to video. When using Zoom/Teams there is a 2-3 second delay from when I hear the voice to when I see the person's mouth move; it's basically unusable.

What I want is a dedicated mini (10 inch) monitor with **`1080p`** resolution that I can use as a "second display" and shift my Teams/Zoom calls to so that I can look directly at the "A Camera" when on meetings. Sadly, I spend 2-5 hours in meetings each day; _never_ less than **2 hours**. I really want to _maximise_ the quality of my presence both audio and video and using the Teleprompter seems like a good plan to up my game.

# Todo

+ [x] Measure the exact dimensions of the reflective glass and "holder" of the Teleprompter to determine the maximum screen size I can get. --> Holder Height: 195mm (this is the constraining dimension), then the glass Width is 221mm but can accomodate a larger screen because it's a mirror; i.e. you can always look to either side in a mirror to see the rest of the "reflected world".
+ [ ] Research
+ [ ] Order the screen
+ [ ] Wait patiently for it to arrive
+ [ ] Install & use the screen!
+ [ ] Thinking of using the mini screen with the HDMI splitter so that it exactly mirrors my "main" monitor.

Sadly the listing does not have precise dimensions, so I'm dubious of the resolution being **`1080p`**. 💭
