Hi guys,

This may sound crazy, but I have to do a presentation with a stretched
output.

The thing is, I have a laptop with a normal screen, and it'll be plugged to
a very big wide screen monitor so that people can see the slides on the
big screen. I have to look at my laptop and present for the people, so
what I'm thinking is make a stretched output on my 4:3 screen which
looks very narrowed and then the effect on the screen will be just as
normal.

Is there an easy option for this?
hmm are you sure that there isn't a way to
choose a graphic mode for you output that do what you want ?
Otherwise, maybe you can make a pdf -> ps,
apply a matrix transformation with ghostscript  to this ps and reconvert to pdf
Or you can use something like
\starttext
\starTEXPage
\externalfigure[slides.pdf][page=1,width=...,height=...]\page
\externalfigure[slides.pdf][page=2,width=...,height=...]\page
\externalfigure[slides.pdf][page=3,width=...,height=...]\page
\externalfigure[slides.pdf][page=4,width=...,height=...]\page
...
\stopTEXPage
\stoptext
