17 inch CRT monitor, what resolution and refresh rate is better?

First of all, the most important thing to follow is personal habits, if you forcibly set it to 1024*768, it may cause harm to your health.

It is recommended that you adjust the refresh rate to 85hz or higher, too low a refresh rate will make your eyes too tired and thus damage your vision.

But it's still recommended 1024*768,If there is no problem with vision,This is more versatile,Because many web pages,Games are made according to this resolution。

With 1024x768 resolution, the number of colors depends on the quality of your graphics card, setting 16 and 32 bit colors, you can't see the difference with the naked eye, the refresh rate is set to or 75, it's not good for the eyes, although you can't usually see the difference, but it's different after a long time.

The 17-inch CRT is generally 1024x768 32-bit color, and 85Hz is good for eye protection.

The 17-inch CRT generally uses 1024x768 32-bit color 70Hz, and if you are not used to it, you can use 1028x1024 which is also more suitable.

1024 768 60hz is OK. You get used to it... Mine is also 17crt. I use 1280 1024

1024x768 resolution 85hz I'm using 100hz right now

Wrong

Generally speaking, the resolution of CRT is adjustable, but due to the limitation of CRT bandwidth, it has an upper limit of resolution at a certain refresh rate. If the upper limit is broken, the refresh rate will be reduced, and the display effect will also be affected to a certain extent. Especially after the human eye adapts to the refresh rate of 75MHz, the eyes will be very uncomfortable if the refresh rate is lower than this refresh rate.

CRT will have the best resolution setting for the waiter, mostly based on the refresh rate of 75MHz, it is best not to exceed this resolution.

However, unlike LED or LCD LCDs, CRTs can display content beyond the optimal resolution, depending on what the graphics card supports. CRT displays of different sizes also have the maximum resolution supported, and it is not possible to exceed them.

CRT displays lose Allah if they are caused by their imaged structure.

I checked something for you, you can take a look.

Display linearity disobeys several aspects of Allah.

1.Distortion caused by poor structure of the deflection coil. Such as trapezoidal, pillow-shaped, etc.

2.Nonlinear distortion due to the nonlinearity of the sweep current.

3.Elongation distortion caused by the radius of curvature of the CRT does not coincide with the center of electron beam deflection.

4.Nonlinear distortion and compensation in the second half of the line-scan front:

The line scan current iy rises regularly, and only in the short time when it starts to be turned on is linear, because there is internal resistance in the deflection coil in the circuit, and the internal resistance of the line tube is not zero when it is saturated, so that when the current increases, the voltage drop on r increases, and the voltage on dy decreases, and the growth rate of iy slows down.

When the magnetic field generated by IY is weakened, the scanning speed of the electron beam will also decrease, that is, when the electron beam scans to the right end, the right side of the reproduced image will be compressed due to the slowdown.

Let's talk about resolution and refresh rate.

CRT displays have bandwidth to transmit signals.

The bandwidth of each display is fixed.

The premium CRT bandwidth will be higher.

The formula for calculating bandwidth is: bandwidth = horizontal resolution * vertical resolution * maximum refresh rate * so when increasing the refresh rate.

The maximum resolution allowed by the display decreases.

Vice versa.

To adjust the display resolution, you need to adjust it through the function buttons that come with the monitor. As shown below:

There are two ways to adjust:

1. Use the automatic adjustment function of the monitor. As shown in the image above, the purple box is selected"auto"Keystroke. (Note: Different monitors have different labels for this function button.) ）

The function of the auto button is to activate the automatic adjustment function of the display. Through the auto button, the monitor automatically adjusts the display screen to the best display state. Including important parameters such as optimal resolution, color, brightness, contrast, clarity, etc.

2. Manual adjustment. By calling up the display function adjustment menu, and cooperating with other buttons of the display, you can manually adjust various parameters of the display.

As shown in the figure above: Description of the key function of the display:

Yellow box selection "Menu": Brings up the "Adjust Functions" menu of the display.

Downward "small triangle": Controls the cursor to move downward.

Small triangle with direction up: Controls the cursor to move up.

source": OK.

auto" : Activates the display auto-adjustment function.

on off : The power of the monitor is turned on.

The size of a CRT monitor refers to the diagonal size of the CRT. The maximum viewing area is the maximum range of graphics that can be displayed on the display. The size of the CRT is usually measured in the length of the diagonal line, in inches (1 inch =, the common ones are 15 inches, 17 inches, 19 inches, 20 inches, etc.).

The display area will be smaller than the size of the display tube. The display area is expressed as the product of length and height, and usually the diagonal length of the visible part of the screen. The viewing range of a 15-inch monitor is about inches, the viewing area of a 17-inch monitor is mostly between 15 and 16 inches, and the viewing area of a 19-inch monitor reaches about 18 inches.

How do I choose the right display resolution? What is the method of choosing the right resolution, the details are as follows: For a 17-inch CRT monitor, does it make little sense to set the resolution of 1600 1200?

In addition, I found that when the LCD is set to different resolutions, it will be blurry, I don't know why? The appropriate resolution is directly related to the size of the display, for CRT monitors, generally speaking, 640 480 is appropriate for those below 14 inches, not more than 800 600, and 800 600 for 15 inches, not more than 1024 768. The resolution of the 17-inch display is 1024 768, if it is higher, the refresh rate may not be able to go up to more than 85hz, the image display quality will not be very good, and it is not good for protecting the eyes.

Of course, there are also some 17-inch monitors that can go up to 1600 1200 resolution while still maintaining a refresh rate of more than 85Hz, which has high requirements for the bandwidth of the display itself, and the display font will become smaller. From the point of view of display principle, LCD display and CRT display are different, and their screen resolution cannot be set arbitrarily, and there is generally an optimal value. Other resolutions may not be set or may not work well.

LCD displays only support so-called true resolution, and only at true resolution can the best image be displayed. When set to a resolution other than the true resolution, there are two ways to deal with it: one is to expand or reduce the display range of the screen, for example, when the screen with a real resolution of 1024 768 is set to 800 600, only the area of the middle 800 600 part is displayed, and the display effect remains the same, but the excess part is a black screen state.

The level of resolution and refresh rate depends on your graphics card and monitor If you want to improve, you first have to see that your monitor supports such a high resolution. Both CRT monitors and graphics cards have their own supported resolutions and refresh rates, which are described in the manual, as long as both support them; The LCD has a fixed physical resolution, only at this resolution the display effect is the best, too high or too low, its refresh rate is generally 60Hz, mainly depends on the attributes of the LCD screen, in general, the LCD screen size is large, the resolution is large. Empty space on the desktop--- right-click ---on the properties --- settings--- select the corresponding resolution.

The size and power consumption of widescreen LCD monitors, this time let's take a look at the best resolution of computer monitors, now most people use LCD monitors, LCD monitors are not like traditional CRT monitors, the range of resolution adjustment supported is very small, especially many widescreen monitors, the default optimal resolution of each size almost does not need to be adjusted, or only supports 2-3 display modes. To determine the best resolution of a display, it is impossible to determine the size of the display alone, and it is not possible to say what is the best resolution of the 15-inch, 19-inch, and 22-inch screens, but it is necessary 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 range of resolution settings that can be set.

The optimal distance between the computer and the computer should be kept at 50 cm to 60 cm, and if the screen size is larger, the distance can be extended to 70 cm as appropriate. Too close is susceptible to radiation damage, and it is also easy to cause myopia or deepen myopia; If the distance is too far, you need to stretch your shoulder arm to be able to use the mouse, which will cause shoulder muscle soreness for a long time.

The height of the computer should be placed at the top of the screen, 30 degrees below the horizontal, and the screen should be slightly tilted upwards by 10 degrees.

In this way, on the one hand, it can reduce the area of cornea and reduce dry eye syndrome; On the other hand, it can relieve the tension of the neck muscles and reduce the occurrence of cervical spondylosis.

The height of the seat should be such that the knees are naturally bent at 90 degrees or leaned forward slightly, and the feet should be flat on the ground. The seat is too high, and the legs are dangling, which can compress blood circulation; The seat is too low, which makes the legs curl up and compresses the internal organs, which affects the gastrointestinal function. The backrest should be tilted forward so that the spine is straight, otherwise prolonged arching will not only compress the internal organs, but also cause a premature hunchback.

It is recommended that you sit facing the screen and do not tilt the computer to the side, otherwise it will be unbalanced for a long time. Not only that, but it also causes excessive bending of the neck, waist, shoulders, and wrists and causes strain. Attention should also be paid to the well-ventilated, well-lit and humid surroundings of the work.

There should be a certain amount of space in the back of the computer, so that there is room for the eyes to expand when looking at the computer.
