To answer from a slightly different perspective: As somebody watching the presentation, I would like to see the following:
- A title (if possible, one that reflects what you're actually going to talk about, rather than what you thought you would be talking about a year ago when you submitted the abstract ;-))
- The authors' names and affiliations. Make it clear who is speaking, in case I don't know you personally.
- An email address for queries (put it at the end as well, but if it's at both ends there's a stronger chance that it'll remain up for long enough to note it down)
Try to resist the urge to turn it into a dense mass of extraneous information and logos. Do not include the following unless you have to:
- The name or city of the conference
- The date
- Funders' logos
If I am at a conference I know where I am. Unless it's been a very long and tiring conference I probably know the date as well. These things may be useful metadata for archival purposes, but it isn't needed by the audience - so put them in small grey text somewhere on the slide, invisible (or at least not attention-grabbing) from a distance.
Similarly, if I'm watching your presentation I probably care about the research, and maybe who did it - not who funded it. Don't include funders logos on the title page unless required to do so; instead, put them on an acknowledgements slide at the end, with anybody else that you owe acknowledgements to.
