Have you ever seen people giving talks in portrait mode? I think all presentation softwares default to landscape mode since the projectors are usually in landscape. So the choice is deliberate.
Here is a calculation. A 4:3 display at 1024*768 has 786432 pixels. If we maintain the 4:3 aspect ratio in landscape, that would be 768*(768/4*3)=768*576 = 442368 pixels, a 43% decrease. Now the speaker may have actually used an aspect ratio of 11:8.5 because of letter sized paper, but I wouldn’t be able to tell since that gives 768*(768/11*8.5)=768*593=455424, still 42%.
So I am curious, why would anyone not want to use those 40% of the available pixels? Do you know what the reason may be?
