LCD default resolution is generally set how much appropriate? I feel that some widescreen display of the resolution settings are not very good will appear ambiguous phenomenon, but are 16:9 of the proportion.
Experts answer
Now most of us use liquid crystal display, LCD monitor is not like traditional CRT display, support the resolution adjustment range is very small, especially many widescreen displays, the default best resolution of each size is almost no adjustment, or only 2-3 display modes are supported. To determine the best resolution of a monitor, depending on the size of the display can not be determined, can not say 15-inch, 19-inch, 22-inch screen The best resolution is the need to comprehensively consider the "screen ratio", "Screen size" and "physical pixels" to determine the best resolution, And the performance of the graphics card also determines the setting range of resolution. Today, let's take a look at the best resolution problem for a computer monitor.
One, the screen screen ratio of the monitor
The current number of display screens (long: wide) has four kinds:
5:4 = 1.25
4:3 = 1.33
16:10 = 1.60
16:9 = 1.77
The higher the screen ratio, the more "flat" the screen looks, the more "positive" the front looks. Screen size and width-height ratios are absolute concepts.
Second, the display common resolution
To see what the common resolution is, because the display resolution concept is relative (the physical resolution is absolute), with different manufacturing processes, graphics card performance will vary, the best resolution may be different, but the screen's theoretical maximum resolution is determined (manufacturing process determination). Here are some common resolutions, not complete, such as 320x240, 640x480 and other resolutions are mostly used on monitors or small-screen handheld devices.
800x640 (width-height ratio 1.25), 800x600 (width-height ratio 1.33)
1024x768 (width to height ratio 1.33),
1280x960 (1.33), 1280x1024 (aspect ratio 1.25), 1280x800 (width-height ratio 1.60), 1280x720 (width-height ratio 1.77)
1400x1050 (1.33), 1440x900 (width-height ratio 1.60), 1440x810 (width-height ratio 1.77)
1600x1200 (width-height ratio 1.33),
1680x1050 (width-height ratio 1.60), 1680x945 (width-height ratio 1.77)
1920x1200 (width-height ratio 1.60), 1920x1080 (width-height ratio 1.77)
2048x1536 (width-height ratio 1.33),
In combination with the screen proportions described above, here you can see that your monitor is suitable for what type of resolution, only need the resolution of the width and height is equal to the computer display aspect ratio, then the screen in the resolution can be full screen display, the wide high proportion does not correspond if not to take the smooth processing (stretching) There will be black edges or incomplete displays.
But in the same proportion there will be a number of resolutions can be selected, such as the 16:9 screen with 1280x720, 1440x810, 1680x945 and 1920x1080 resolution, then the specific support of which or several of these are determined by the manufacturing process, That is, the vertical and horizontal directions are all designed according to how many pixels. The final resolution that can be set (the resolution that the user sees on the computer) will also be determined by the graphics performance and drivers. Because graphics technology than physical display technology to advance, so the general graphics card will not drag the rear legs of the display, that is, the display can show how much resolution, graphics cards are mostly supported, unless it is too old graphics card.
So the result of the comprehensive consideration is that each LCD has only a limited number of 2-3 resolution to choose from, and some widescreen also support the resolution of the aspect ratio, such as 16:9-screen support 5:4 proportional resolution is fully considered the actual use of the need, such as compatible with the old graphics cards, game programs and so on.
Three, screen ratio and resolution comparison
The above parameters are summarized as follows:
5:4 screen corresponding resolution (800x640, 1280x1024 、...)
4:3 screen corresponding resolution (800x600, 1024x768, 1280x960, 1400x1050, 1600x1200, 2048x1536 、...)
16:10 screen corresponding resolution (1280x800, 1440x900, 1680x1050, 1920x1200 、...)
16:9 screen corresponding resolution (1280x720, 1440x810, 1680x945, 1920x1080 、...)
Typical size display screen and the best resolution comparison table:
In addition, the current large-screen LCD screen is 16:10 or 16:9 of the proportion, especially now high-definition LCD TV with 1280x720 (16:9), 1920x1080 (16:9) mainly, of course, their display size is relatively large (30# above), even at the highest resolution display, If you look closer, it's still miserable, because the LCD TV panel has too much pixel spacing.
So, how do you determine the best resolution for your own display?
The method is very simple, for liquid crystal displays, if it is the original display and graphics card, only need to adjust the resolution to the maximum range can be (note: General and physical resolution), if it is a self-assembled assembly machine, without the installation of a display driver, the only reference to the proportion of the table to choose the best resolution (generally also the largest) Ensure full screen display can be. If you are unsure about setting the resolution, it is best to check the instructions on the display or notebook for a specific resolution support list.
If it is a CRT monitor, because its display mechanism is different from the liquid crystal display, in theory CRT monitor can display any resolution that meets the screen ratio without the black edge (note: In fact, due to the refresh frequency and design restrictions, when exceeding the best resolution of the display, The screen will be automatically reduced to take care of the entire screen full refresh, so the CRT display resolution adjustable range is relatively wide, or the comfort of the appropriate choice for the same width and height ratio of the resolution.
Third, the display resolution adjustment method
1, how to adjust the display resolution on Windows 7?
Now that you have written a complete point, and then introduce the display resolution adjustment method, with the Windows 7 operating system as an example, in the desktop space, click the right mouse button, in the pop-up menu, select "Screen resolution."
The following figure, click the Resolution list box, you can see the current display resolution support, select Click OK.
2, how to adjust the display resolution on Windows XP?
If it is a Windows XP system, modify the resolution steps as follows:
1. Click the right mouse button in the desktop space and select Properties in the pop-up menu.
2. In the Display Properties window, click the "Settings" tab.
3. Adjust the screen resolution scroll bar, finally click OK, the following figure:
About the monitor refresh frequency problem, the LCD default refresh rate is best not to adjust (60HZ), CRT more than 75HZ can.
