Why should the resolution of the laptop screen be adjusted?

As long as your graphics card is fine, the higher the tune, the clearer it will be.

Right-click on "Properties" - Screen Resolution" in the blank space of the desktop, where you can adjust the resolution and orientation of the screen. Proper adjustment is sufficient; When adjusting to the appropriate position, click "Apply" In many cases, when the adjustment is not very satisfactory, you can also adjust other items, after the adjustment, click "Apply". After a simple adjustment, we will find that the desktop becomes clearer.

According to the actual needs and feelings of use, graphic design, programming needs to display as many things as possible in the screen, naturally high-resolution is better, but if there is an unintentional demand, then the high-resolution screen may not be needed.

Generally speaking, when we use a computer, it is best to set the resolution to the best resolution of the monitor, which is the maximum resolution supported by the monitor. If the purchased monitor is inch and supports 1920x1080 resolution, then we can set it to 1920x1080 resolution on the computer.

Different monitors have corresponding screen resolutions, if a 19-inch monitor with a screen resolution of 1024*768 will look very uncomfortable, so, if you feel that the computer screen looks very tired and uncomfortable, it is likely that the screen resolution of the computer is not set correctly.

14" CRT monitor 800 600;17" LCD or CRT monitor 1024 768;19 inch LCD monitor (plain screen) 1280 1024;19" LCD monitor (widescreen) 1440 900;20-inch LCD monitor (widescreen); 1600×900；22" LCD Widescreen 1680 1050;24" LCD monitor (widescreen) 1920 1200.

The resolution adjustment method of Windows XP system is actually very simple, first enter the computer desktop, right-click in the blank space of the desktop--- select "Properties" in the pop-up selection menu to enter.

After entering the desktop properties display window above, we click on the "Settings" option at the top, and then you can switch to the display settings interface, and you can choose to adjust the size of the resolution in the display settings interface, and then select OK to complete the adjustment, and set it according to the following settings.

Adjust the screen resolution: Right-click on the blank space of the desktop, select "Properties", switch to the "Settings" tab, there is a slider below "Screen Resolution", pull left or right to adjust.

Normally, there are at least five or more modes for screen resolution, such as more than five such as 900. In most cases, the problem that the resolution cannot be adjusted is caused by the abnormal graphics card driver or the lack of installation of the graphics card driver.

The solution to the screen resolution can't be adjusted:

1. Check whether the graphics card driver is normal, right-click "My Computer", select "Properties", switch to the "Hardware" tab, click "Device Manager", and check whether there is an exclamation mark or question mark in the "Display Card" in the "Display Card" in the pop-up "Device Manager" window, or whether an exclamation mark or question mark appears in other places in the Device Manager. If there is, it means that the card driver or other hardware driver is abnormal or not installed.

3. Repeat the steps of the first step to see if all the exclamation marks and question marks in the device manager have disappeared, if they disappear, the driver is installed normally, and right-click on the blank space on the desktop. Select "Properties", switch to the "Settings" tab, there is a slider under "Screen Resolution", pull left or right to adjust, and the problem of not being able to adjust the resolution should be solved.

In short, basically the problem that the resolution cannot be adjusted is caused by the abnormal graphics card driver or the lack of installation of the graphics card driver, and reinstalling the graphics card driver can solve the problem.

1. Take win10 as an example, right-click on the blank space of the desktop, and select "Display Settings".

2. On the jump interface, select "Display" on the left, and then set "Change the size of text, apps, etc." to 100% (recommended) in the zoom and layout, and set the display resolution to (recommended).

3. Scroll down and click Advanced Display Settings.

4. Here you can see what maximum resolution your computer screen supports, and you can also adjust it according to this.

First, right-click on the blank space of the desktop and select [Properties] in the pop-up menu. Select the settings in the Display Properties tab, and you will see a "Screen Resolution" at the bottom left, and you can move the control arrows to change the resolution of the screen. Find the value you want and click "OK".

If the above steps can't change the computer resolution, we can click Advanced in the lower right corner of the Display Properties tab. In the pop-up tab, select Adapters, and then click List All Modes in the lower left corner. In the list of valid modes, you can select the appropriate resolution and click OK.

Naturally, the resolution of the computer has changed.

Traditional CRT displays support more flexible resolutions, while the pixel pitch of liquid crystals has been fixed, so the supported display modes are not as many as CRTs. The optimal resolution of liquid crystals, also known as maximum resolution, is at which the liquid crystal display can display the best image. When the LCD presents a lower resolution display mode, there are two ways to display it.

The first is centered display: for example, when displaying an SVGA 800 600 on a screen with an XGA 1024 768, only the 800 600 pixels in the center of the screen are presented, and the other pixels that are not rendered remain dark. At present, this method is rarely used.

The other is called extended display: when displaying a picture with a lower than optimal resolution, each pixel is expanded to adjacent pixels by a differential algorithm, so that the entire picture is filled. This also makes the picture lose its original clarity and true color.

Since the maximum resolution of the LCD display of the same size is the same, the ** of the liquid crystal of the same size is generally not related to the resolution.

The optimal resolution of the display should not be arbitrarily set.

It is usually described in the manual of the machine, because the resolution corresponds to the number of pixels visible.

For example, the number of pixels designed when the display first appeared was 800*600,Then it's best to set it to800*600,If you have to set it to1024*768,It's okay,But there will be a situation where several pixels are displayed as one,That's when a part of the pixels is lost,Or lose the details。

Because your machine is LCD, and the LCD display is in accordance with the standards stipulated by the state, the minimum is 1024*768 for 14-15 inches, and the minimum is 1240*1024 for 17 inches

The 19-inch one is also 1240*1024.

Why is the specified resolution of 19 inches also 1240*1024?

Because for the average user,Whether you are watching *** or playing games,The resolution is not larger than this,And it's not good if the resolution is too high,Because the number of resolutions means how much is needed,Take the resolution of 1240*1024 for example,1240*1024=1269760 pixels,And now the color quality of the display is generally 24 bits or 32 bits,Then a pigment will need 24bit 8=3 bytes,Or 32bit 8=4 bytes of video memory. Multiply by the number of pixels just now 1269760*4=5079040 bytes of video memory, which means that the graphics card needs to process so much data before the picture moves. It will put an unnecessary burden on the graphics card.

If you watch a movie, the speed of 24 frames per second can be calculated as 5m*24=120m. That is to say, the graphics card must be more than 120m to better display. Of course, there are some technologies that don't use so much video memory, so it's useless to have a larger resolution.

The advantage of a 19-inch display over a 17-inch display is that each pixel is a little larger and you can see it more clearly.

It's a bit too much,Briefly talk about the refresh rate,The general TV refresh rate50Hz,But the display is generally above75Hz,Because the higher the refresh rate,The more real what you see,That is to say, when the eyes are looking at the table,Chairs,The refresh rate is the refresh rate of the eyes,And when looking at the display,The refresh rate of the eyes will not be exactly the same as the display,So the display should be faster,So that the eyes will not feel that the display is flickering,The higher the refresh rate, the better,Protect the eyes。 To add that, the refresh rate of the eyes is about 24Hz, because the movie happens to be based on the refresh rate of the eyes.

However, because you are an LCD monitor, the LCD display color is gradual, because the color changes slowly, so it will not hurt your eyes, and the default 60hz can completely protect your eyes.

Having said all that, I don't know if you understand.

In short, 1240*1024 is OK, 60Hz is OK.

Also pay attention to your body, you can't be in front of the computer all the time.

There are several ways to adjust your computer resolution:

1. Right-click the blank space of the desktop, select "Properties" - "Settings", there is a "Screen Resolution" at the bottom left of the window of the Settings tab, drag the control block to the left and right to change the resolution of the screen (pay attention to the numbers below each drag), and you can click "OK" after confirming a certain resolution value.

2. (Take Intel graphics card as an example) Right-click the blank space of the desktop, select "Display Mode" - "True Color" - "1024 * 768" (choose here as needed, but it is not recommended to be too high).

3. (Take Intel graphics card as an example) right-click on the blank space of the desktop, select "Properties" - "Settings", there is an "Advanced" - "Adapter" - "All Modes" at the bottom right of the window of the settings tab, and select a suitable mode combination (pay special attention not to choose too high refresh rate Hertz number).

4. Adjust through the control panel. First, click on the control page at the beginning to enter the interface of the control page. Once we are in the control panel interface, we find Appearance and Personalization.

Then, enter the appearance and personalized interface, find the display in the interface, enter the display interface, you will see the adjustment screen resolution on the right side of the computer, click to enter, you will see the interface such as adjusting the screen resolution.

Common optimal resolution for different sizes of screens (the same size, different displays, the best resolution may also be different):

19-inch monitor: 1440x900 (16:10).

20 inch monitor: 1600x900 (16:9) 1600x1200 (4:3).

Inch monitor: 1920x1080 (16:9).

22-inch monitor: 1680x1050 (16:10) 1920x1080 (16:9) 1920x1200 (16:10).

23-inch monitor: 1920x1080 (16:9) 1920x1200 (16:10).

Inch monitor: 1920x1080 (16:9).

24 inch monitor: 1920x1200 (16:10) 1920x1080 (16:9).

26-inch monitor: 1920x1200 (16:10).

27-inch monitor: 2560x1440 (16:9).

30-inch monitor: 2560x1600 (16:10).

Check whether the resolution can be changed, and if not, select the next step.

Steps: "Right-click" on the computer desktop - after the pop-up box pops up, select "Screen Resolution" - adjust "Resolution", click the inverted triangle to adjust it. Or win – control panel – adjust the "screen resolution".

1. The resolution cannot exceed the bearing capacity of the graphics card, such as the low-grade graphics card can only be adjusted to 1440 900 at most.

2. Adjust the resolution according to the size of the screen, the screen resolution is high, the fineness of the text image is high, and the text image is small; The screen resolution is low, the fineness of the text image is low, and the text image is large. However, too high resolution will make the text and images smaller and affect the observation effect, and too high resolution will also make the screen unable to display and become a black screen; Adjusting the resolution too high will increase the burden on the graphics card, increase the heating, cause the display to be unsmooth, or cause the screen to freeze, blur or freeze when playing large games, reduce the life of the graphics card, and even burn out the graphics card or motherboard.

3. Adjust the resolution according to the aspect ratio of the screen, otherwise the display will be deformed into a flattened, thin and tall shape.
