1 00:00:00,480 --> 00:00:01,480 Hello. 2 00:00:01,480 --> 00:00:05,000 I'd like to speak with you today about screen resolution and changing the screen resolution 3 00:00:05,000 --> 00:00:06,000 in Windows 7. 4 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 5 00:00:11,049 --> 00:00:12,570 on your screen. 6 00:00:12,570 --> 00:00:17,550 Imagine, if you will, that your screen is overlaid with a very finely meshed grid. 7 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 8 00:00:23,009 --> 00:00:25,050 individual squares. 9 00:00:25,050 --> 00:00:29,780 Pretend that each square could be exactly one color: It could be yellow, or it could 10 00:00:29,780 --> 00:00:33,860 be green, but it can't be yellow and green. 11 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 12 00:00:40,050 --> 00:00:44,780 going to be a fixed, physical size -- you can't stretch your monitor or shrink your 13 00:00:44,780 --> 00:00:50,321 actual monitor, but you can change how many pixels are displayed on your monitor: Pixels 14 00:00:50,321 --> 00:00:55,450 going across for your horizontal resolution, and pixels going up and down for your vertical 15 00:00:55,450 --> 00:00:56,510 resolution. 16 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 17 00:01:05,730 --> 00:01:09,750 of pixels going across, and lots and lots of pixels going down. 18 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 19 00:01:18,720 --> 00:01:20,580 and down. 20 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, 21 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. 22 00:01:32,990 --> 00:01:35,860 That's what happens when you see the triangle. 23 00:01:35,860 --> 00:01:42,310 The way Paint stores images, it stores colors within specific pixels, and as I zoom in, 24 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 25 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 26 00:01:53,640 --> 00:01:57,530 here would be another pixel, and so on. 27 00:01:57,530 --> 00:02:02,290 So how do you change your screen resolution? 28 00:02:02,290 --> 00:02:07,000 You right-click on a blank part of the screen, and choose "Screen Resolution." 29 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, 30 00:02:12,629 --> 00:02:16,450 you can see different options available to you. 31 00:02:16,450 --> 00:02:24,390 My monitor is currently set to have the highest resolution being displayed: 1680 across; 1050 32 00:02:24,390 --> 00:02:26,670 pixels up and down. 33 00:02:26,670 --> 00:02:31,930 Suppose I were interested in having a lower resolution. 34 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 35 00:02:35,030 --> 00:02:36,030 larger. 36 00:02:36,030 --> 00:02:39,900 Let's make this a little bit more extreme. 37 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," 38 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? 39 00:02:54,260 --> 00:03:00,150 If I don't make any specification, it will automatically revert back to my original settings. 40 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 41 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 42 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. 43 00:03:20,430 --> 00:03:21,780 Thank you very much.
