  • 0:00 - 0:01
    Hello.
  • 0:01 - 0:05
    I'd like to speak with you today about screen
    resolution and changing the screen resolution
  • 0:05 - 0:06
    in Windows 7.
  • 0:06 - 0:11
    Before I do that, however, I'd like to talk
    a little bit about how images are displayed
  • 0:11 - 0:13
    on your screen.
  • 0:13 - 0:18
    Imagine, if you will, that your screen is
    overlaid with a very finely meshed grid.
  • 0:18 - 0:23
    Now, in point of fact, the grid would be so
    fine that you would not be able to see the
  • 0:23 - 0:25
    individual squares.
  • 0:25 - 0:30
    Pretend that each square could be exactly
    one color: It could be yellow, or it could
  • 0:30 - 0:34
    be green, but it can't be yellow and green.
  • 0:34 - 0:40
    Each of those squares would be called a "picture
    element," or a pixel, and your monitor is
  • 0:40 - 0:45
    going to be a fixed, physical size -- you
    can't stretch your monitor or shrink your
  • 0:45 - 0:50
    actual monitor, but you can change how many
    pixels are displayed on your monitor: Pixels
  • 0:50 - 0:55
    going across for your horizontal resolution,
    and pixels going up and down for your vertical
  • 0:55 - 0:57
    resolution.
  • 0:57 - 1:06
    Now I 've got a Paint image here that is currently
    simulating a high resolution; lots and lots
  • 1:06 - 1:10
    of pixels going across, and lots and lots
    of pixels going down.
  • 1:10 - 1:19
    As I zoom in on this image, I am simulating
    having fewer and fewer pixels going across
  • 1:19 - 1:21
    and down.
  • 1:21 - 1:27
    If you are having fewer pixels being displayed
    on the monitor, and the monitor is a set size,
  • 1:27 - 1:33
    and the pixels are going to cover the entire
    monitor, each pixel will have to be larger.
  • 1:33 - 1:36
    That's what happens when you see the triangle.
  • 1:36 - 1:42
    The way Paint stores images, it stores colors
    within specific pixels, and as I zoom in,
  • 1:42 - 1:48
    I get to the point where the image is pixelated;
    I can actually see where the individual pixels
  • 1:48 - 1:54
    would be, so I can see that this little square
    here would be one pixel; this little square
  • 1:54 - 1:58
    here would be another pixel, and so on.
  • 1:58 - 2:02
    So how do you change your screen resolution?
  • 2:02 - 2:07
    You right-click on a blank part of the screen,
    and choose "Screen Resolution."
  • 2:07 - 2:13
    You should see "Resolution" with a drop-down
    list, and if you click on the drop-down arrow,
  • 2:13 - 2:16
    you can see different options available to
    you.
  • 2:16 - 2:24
    My monitor is currently set to have the highest
    resolution being displayed: 1680 across; 1050
  • 2:24 - 2:27
    pixels up and down.
  • 2:27 - 2:32
    Suppose I were interested in having a lower
    resolution.
  • 2:32 - 2:35
    Maybe my eyesight's not quite so good and
    I'd like to have things look a little bit
  • 2:35 - 2:36
    larger.
  • 2:36 - 2:40
    Let's make this a little bit more extreme.
  • 2:40 - 2:47
    I'd like to see how this looks, so I'll click
    on "Apply," and when I click on, "Apply,"
  • 2:47 - 2:54
    I am given the options: Do I want to keep
    these settings or do I want to revert back?
  • 2:54 - 3:00
    If I don't make any specification, it will
    automatically revert back to my original settings.
  • 3:00 - 3:05
    This is a failsafe mechanism, in case I wound
    up making changes such that I couldn't even
  • 3:05 - 3:11
    see what I was doing on the screen. It has
    since reverted back, and I'm going to cancel
  • 3:11 - 3:20
    out of here, and so you have now seen how
    you can change the resolution of your screen.
  • 3:20 - 3:22
    Thank you very much.

Sandbox
Description:

You can use this Sandbox to try out things with the Amara tool.

The video that is primarily streaming here is http://www.youtube.com/watch?v=ZU2kyr9jRkg , which is completely blank. But you can go to the URLs tab to add the URL of another video and make it primary.

Please remember to download your subtitles if you want to keep them, as they will get deleted - and the streaming URL reverted to the blank video if you changed it - after a week or two,
