[OS X TeX] Best iPad PDF viewer for math?

[Nicolae Garleanu]

Hi Gary,

Could I ask in which app you open the document on the iPad that you share via HDMI cable? And do you sometimes write on this document (pdf, I assume) during the presentation?

Here is what I know. Using Goodnotes, if I connect via Airplay — that is, share screen in Zoom by choosing "iPad via Airplay” — then Goodnotes enters presentation mode and I can choose the option that I like among the three (I like “mirror full page,” which hides the interface and has nice page transitions). However, if I connect via cable (USB-C, not HDMI), then I am just sharing the full screen of the iPad, which is nowhere near as nice. I would like the safety of a wired iPad-macbook connection, but Goodnotes with Airplay is quite a bit better than simply sharing the screen.

On the recording note: In the spring I taught by logging in (using the same ID) from desktop computer (for video/audio and to monitor chats etc) and MS Surface (for slides; this screen almost always shared). What I saw of the recordings seemed fine. Furthermore, no student raised any issue. We also have a dedicated staff member that was logged on to make sure that technology worked (e.g., that I had restarted recording once I paused it for the break); he mentioned at some point that the recordings were fine (he checks them before posting for the students).  Ross’s issue may be specific to institutional set-up, etc. I haven’t tried this with an iPad yet, hadn’t realized it could be problematic. At least it is easy to check, by running a brief meeting by myself whenever and viewing the recording a couple of minutes later.

Best,
Nicolae

I learned just a couple of weeks ago that you can do this and it works *very* well. This can also be done wirelessly using AirPlay if both devices are on the same WiFi network.

This is what I did in the spring after we went online. It also *seemed* to work well. See below.

What issue are you seeing with cloud recordings in this mode? I did notice that my cloud recordings were very low resolution when done this way and were much higher resolution when I shared my iPad screen when it's connected to my Mac.

Classes start Monday and I am still working out all the technology details.
