Now that there are useful authoring environments for TeX documents available on the iPad, I would wish to be able to present their results (e.g., a beamer document) directly from an iPad via the VGA connector to a "physical" beamer (or Television set) instead of using a laptop.
So my question is, are there possibilities and if so which?
My limitation right now is that I have an iPad1; I think the newer hardware can mirror the iPad screen. However, even for newer hardware app-based video output might be preferable to screen mirroring as this allows the app to suppress option buttons etc on the video screen.

The iPad 1 supports screen mirroring only for certain apps. For some discussion of this, see
That being said, however, it seems that many apps do support screen mirroring. The following list seems to be quite extensive and includes a few apps that can display PDF, which is what you would need to display TeX output. Pipiro notes in the comments that Goodnotes can also mirror on the iPad 1.
Subsequent iPad models support mirroring for all apps, so you should be able to use your favourite PDF viewer to display PDFs on current versions of the iPad.
