Hi everybody my name is Todd Reed and i've been selling projectors here at Projector
People for over twelve years now,
and we're just gonna take a basic look at aspect ratio and resolution
now the two go hand in hand and hand so we'll discuss them together as we go along
we just want to make sure you have a good understanding exactly what you're
seeing on the spec sheet
numbers everything what they mean
so first off the definition
resolution is the number of pixels that the projector can project out. There's
going to be a width number and a height number...
basically like the square footage of a room. It's just letting you know exactly
how many pixels are up on the screen
aspect ratio is the shape
that the resolution takes whether it be a square rectangle
so you've got the aspect ratio which is the shape that the picture takes
and resolution which is a number of pixels inside that shape
so what we're gonna do as we're gonna put up three resolutions on the wall
and we're gonna go through them and talk about the advantages and the best
applications for those resolutions
Allright? So let's get started.
What we're gonna look at is we're gonna look at three main resolutions
We're gonna look at XGA,
WXGA, and high-definition.
okay those are the three main ones that you're gonna come across when you're
shopping for the projector.
now the first one is XGA and as you can notice it's almost a square has an
aspect ratio a 4:3 just think about a square is 4:4
this is a four three aspect ratio
this is the oldest resolution we'll talk about and the lowest resolution
but still has a good place in the market
uh... the resolution is 1024 by 768 pixels
now this resolution is still great for business applications church
applications, power point,
media shout - anything like that. This guy still does a great job.
now the reason it's still real popular
is it's low cost.
now you can get these guys for under about four hundred dollars now so real good as far
as your budget gets
also you can get these guys down around three pounds, so for businesspeople they're
very portable
uh... very good as far as the business application goes,
so even though it's the oldest resolution and the lowest it's still real popular in the
marketplace and you can get a lot for your money out of the XGA.
Next is kind of a new kid on the block
it's WXGA
the resolution on WXGA
is 1280 x 800
so it has more pixels than the XGA does so you get a little more information on the
screen
uh... great for spreadsheets and things like that. We've got a lot information,
you'll get a couple more rows on the image when you have a
spreadsheet.
Now the aspect ratio is 16:10, a little more of a rectangle
so you're future proofing yourself a little more with the WXGA, so I
recommend you go this way if you can,
but this budget is a couple more bucks than the XGA.
So you just wanna make sure this fits into the budget - but if you can, this projector will
kind of future proof you with the newer computers
and some of the newer devices that have HDMI.
And of course last but not least everybody loves HD...
We all want HD.
you've got 1920 x 1080 pixels
and it's a 16:9, so it's a little narrow
rectangle - really getting into high def.
Now of course you want this for home theater; if you're home theater - this
resolution is a no brainer
Great for conference rooms, great for photography,
great for Autocad type programs where you really need a lot more detail, a lot
of clarity in the picture
This is the way to go.
now the down side to high definition
is size right now, we can't get much lower than about eight pounds as far as
the weight goes.
So you've got to wrestle with weight - you're not gonna be running on an airplane with this if
you're a traveling salesman.
As far as the price goes. you're starting in the entry level around a
thousand dollars so budget may come into play as well
You just gotta decide, but if you can
high def is certainly the way to go to get the most information and the clearest
picture possible.
All of these guys
will mate up to your laptop,
but the key is you want to try and get the resolution
of the projector close to the native resolution of your computer.
That way the picture will look the best, you'll have the clearest, best image.
Okay guys what we're going to do is we're gonna show you real quick what a
16:9 signal looks like coming through a regular 4:3 projector,
just so you understand that they can handle
different aspect ratios and resolutions.
So what we're going to do here is as you can see we've got a 4:3 aspect
ratio up there right now
we're going to send a 16:9 movie (if you want cut the lights we'll go ahead and do
that ) -
Now what we're gonna do real quick
we're gonna go down and we're gonna get the movie in there.
now remember you've got your
4:3 right now,
when the movie pops in
(it takes just a second) -
Now you got your 16:9 inside the 4:3.
This little 4:3 projector can handle it.
okay we just want to give you an idea of what it looks like with the different
aspect ratios and resolutions
Now lets walk down here real quick
and we're gonna look at high definition.
With high-definition, you've got your 16:9 aspect ratio, right?
Okay - we're just gonna pop it into 4:3 real quick
and what you'll see,
you're semi-square
inside the rectangle.
So you've got your 4:3 and your 16:9.
So again,
um...
if you have any questions on anything like that as far as the aspect ratios
correlating with the projectors
the best thing to do is give us a call at projector people. We're happy to help
you out. We're
here to answer any questions you have so give us a call.
