I give lots of presentations, using a smaller, older laptop
with HD15 ("VGA" and other resolutions) video. The docking
cradle has DVI, but I prefer not to lug along the extra weight,
so I have a HD15 to DVI and HDMI adapter.
About 10% of venue projectors are old and HD15 only, about 10%
are HDMI only screens, most have more than one interface, some
have all three, and even have ethernet. Most problems stem
from projector and screen aspect ratio, with older systems
using 4:3 and newer systems using 16:10 or 16:9 or some
other media-focused aspect ratio.
