above faults should first check whether the computer's resolution and the refresh frequency match the projector. We know that notebook computer hardware configuration is high, the resolution can be achieved and refresh frequency are higher. But if the projector exceeds the maximum resolution and refresh frequency, it will appear above phenomenon. The solution is simple, the computer's display adapter to lower the two parameter values, the general resolution does not exceed 600*800, refresh freq

standard for applications that have a frequency range between 2G to 10G Hertz. We can see that 802.16.1 is responsible for very high frequencies, and its work is at the forefront of these three groups. Because of its unique bandwidth, 802.16.1 is most likely to attract industry interest in the future. The role of the 802.16 wireless service is to establish a communication path between the user site and the core network, which can be a public teleph

were quickly modified to 24,000bps and subsequently corrected to 28,800bps. The updated V.34 (1996) modem supports the 33,600bps rate. The bandwidth of such a modem reaches 10 bits per hertz, almost to the theoretical limit. Recently, many companies have introduced 56.6kbps analog modems that connect to standard telephone lines. However, the modem's operating mode is asymmetrical (it works at the upstream end at the speed of a normal modem) and requi

First, the display refresh rate setting is correct
Check the method is: in our computer desktop blank area right---properties--settings-Advanced---Monitor the following figure:
You can see that the display's refresh rate is set to "60 Hz", which is why the monitor screen is constantly shaking. Set the new frequency to "75" and then click OK to return to the desktop. There is only 60 hertz in the notebook, so there is no need to adjust the value,
In the CRT era, screen flicker is a common fault, usually caused by insufficient refresh frequency of the display card. Many users do not know what the refresh rate is, plus the system default is 60 Hertz, many users often use a lot of years low refresh rate to understand the CRT screen can not flicker.
To the liquid crystal display era, environmental protection without radiation, and no flicker and other features become the biggest selling point o

A sound is basically a sine wave traveling in the air. it is characterized by a power and a frequency. the power determines the sound loudness and the frequency determines its pitch. if you are not familiar with this phenomenon, I
