WEBVTT 00:00:00.480 --> 00:00:01.480 Hello. 00:00:01.480 --> 00:00:05.000 I'd like to speak with you today about screen resolution and changing the screen resolution 00:00:05.000 --> 00:00:06.000 in Windows 7. 00:00:06.000 --> 00:00:11.049 Before I do that, however, I'd like to talk a little bit about how images are displayed 00:00:11.049 --> 00:00:12.570 on your screen. 00:00:12.570 --> 00:00:17.550 Imagine, if you will, that your screen is overlaid with a very finely meshed grid. 00:00:17.550 --> 00:00:23.009 Now, in point of fact, the grid would be so fine that you would not be able to see the 00:00:23.009 --> 00:00:25.050 individual squares. 00:00:25.050 --> 00:00:29.780 Pretend that each square could be exactly one color: It could be yellow, or it could 00:00:29.780 --> 00:00:33.860 be green, but it can't be yellow and green. 00:00:33.860 --> 00:00:40.050 Each of those squares would be called a "picture element," or a pixel, and your monitor is 00:00:40.050 --> 00:00:44.780 going to be a fixed, physical size -- you can't stretch your monitor or shrink your 00:00:44.780 --> 00:00:50.321 actual monitor, but you can change how many pixels are displayed on your monitor: Pixels 00:00:50.321 --> 00:00:55.450 going across for your horizontal resolution, and pixels going up and down for your vertical 00:00:55.450 --> 00:00:56.510 resolution. 00:00:56.510 --> 00:01:05.730 Now I 've got a Paint image here that is currently simulating a high resolution; lots and lots 00:01:05.730 --> 00:01:09.750 of pixels going across, and lots and lots of pixels going down. 00:01:09.750 --> 00:01:18.720 As I zoom in on this image, I am simulating having fewer and fewer pixels going across 00:01:18.720 --> 00:01:20.580 and down. 00:01:20.580 --> 00:01:26.750 If you are having fewer pixels being displayed on the monitor, and the monitor is a set size, 00:01:26.750 --> 00:01:32.990 and the pixels are going to cover the entire monitor, each pixel will have to be larger. 00:01:32.990 --> 00:01:35.860 That's what happens when you see the triangle. 00:01:35.860 --> 00:01:42.310 The way Paint stores images, it stores colors within specific pixels, and as I zoom in, 00:01:42.310 --> 00:01:48.220 I get to the point where the image is pixelated; I can actually see where the individual pixels 00:01:48.220 --> 00:01:53.640 would be, so I can see that this little square here would be one pixel; this little square 00:01:53.640 --> 00:01:57.530 here would be another pixel, and so on. 00:01:57.530 --> 00:02:02.290 So how do you change your screen resolution? 00:02:02.290 --> 00:02:07.000 You right-click on a blank part of the screen, and choose "Screen Resolution." 00:02:07.000 --> 00:02:12.629 You should see "Resolution" with a drop-down list, and if you click on the drop-down arrow, 00:02:12.629 --> 00:02:16.450 you can see different options available to you. 00:02:16.450 --> 00:02:24.390 My monitor is currently set to have the highest resolution being displayed: 1680 across; 1050 00:02:24.390 --> 00:02:26.670 pixels up and down. 00:02:26.670 --> 00:02:31.930 Suppose I were interested in having a lower resolution. 00:02:31.930 --> 00:02:35.030 Maybe my eyesight's not quite so good and I'd like to have things look a little bit 00:02:35.030 --> 00:02:36.030 larger. 00:02:36.030 --> 00:02:39.900 Let's make this a little bit more extreme. 00:02:39.900 --> 00:02:46.859 I'd like to see how this looks, so I'll click on "Apply," and when I click on, "Apply," 00:02:46.859 --> 00:02:54.260 I am given the options: Do I want to keep these settings or do I want to revert back? 00:02:54.260 --> 00:03:00.150 If I don't make any specification, it will automatically revert back to my original settings. 00:03:00.150 --> 00:03:04.810 This is a failsafe mechanism, in case I wound up making changes such that I couldn't even 00:03:04.810 --> 00:03:11.340 see what I was doing on the screen. It has since reverted back, and I'm going to cancel 00:03:11.340 --> 00:03:20.430 out of here, and so you have now seen how you can change the resolution of your screen. 00:03:20.430 --> 00:03:21.780 Thank you very much.
