Sometimes our monitor will appear ambiguous situation, this kind of situation is more common, encounter this kind of situation, what should we deal with the malfunction of the monitor when we encounter the ambiguity? The display of the content is ambiguous that the CRT focu

know is the design habits or what other reasons, the bias color fault red is the most likely, followed by the blue, and finally the green:). In addition, there is a relatively easy to make detours cause of the fault-screen dust too much lead to screen display when red! This type of failure occurs in the color tempera

The visual angle is the angle by which the user can observe all the contents of the screen clearly from different directions. Because the provision of LCD display light source refraction and reflection after the output has a certain direction, in excess of this range of viewing will produce color distortion, CRT monitor will not have this problem. The visual angle size determines the size of the user's visu

laptops and PDAs, and it plays a very important role in projectors, and it is beginning to seep into the desktop display market. LCD Features Thin fuselage, space saving Compared to the bulky CRT monitors, the LCD displays as much as One-third of the space in the former. Save electricity, do not produce high temperature It belongs to Low-power products, can be done completely without heat (the main power consumption and heating part of the exist

Setting method for display resolution too low: (1), in the desktop space right click, select Properties, pop-up the following prompt box, select Settings, in the screen area to adjust the corresponding resolution. (2), if the choice of resolution can not find the required resolution, click Advanced, in the New pop-up window to select the monitor, will hide the monitor can not display the mode tick cance

Today turned on the computer to find a strange thing, see the Windows login box is very vague, as if the resolution suddenly changed, into the system, the desktop icon is not clear, it must be the display resolution is small, but how can the resolution change? The problem seems not so simple. It is not so simple, open

Now the general household display resolution is mostly around 1024768, if set too low (some even low to 640480), then in the Windows environment may be to start to bring the screen layering phenomenon, affecting the normal output of video resulting in black screen; If set too high ( Resolution setting is higher than 1024768, then the graphics chip may not support too high resolution and appear the picture o

　　1. Monitor display ratio is 4:3 The display ratio is 4:3 of the 19-inch display is generally the older model of the display, its general best resolution: 1280x1024. 　2. The display ratio of the display is: 16:10 Monitor displ

The monitor just opened the machine all normal, but after a while there is no grating, no image, and a slight squeak issued. From the phenomenon of failure, the display is a failure of instability. Using the cooling method and heating method to check all the main circuits of the display, the problem is found, and then

The LCD has the following differences from the CRT monitor. Note One: Refresh frequency The refresh rate is the vertical scan frequency (field frequency) of the monitor, which refers to the number of times the electron gun is scanned across the screen per second, in Hz (Hertz). For CRT monitors, the image displa
