First, retrieve the display refresh frequency
Have you ever met a phenomenon like this? After you format the hard disk reload system, you want to change the display refresh rate, open the Display Properties dialog box and found only "default adapter" and "Optimization", all the other options are missing! Sometimes even these two are not! Check the driver for the video card, clearly installed correctly. So, what the hell is going on here?
Most people when installed, for graphics drivers are often very focused on, and generally can be installed correctly, but for the display driver is usually not noticed, but in the installation let Windows automatically recognize. However, Windows sometimes does not recognize the model of the monitor correctly, and therefore cannot install the most suitable driver, which leads to the above phenomenon. In this case, Windows usually recognizes the monitor as either Plug and Play monitor or unrecognized monitor, which is visible in both display properties and System properties.
The right thing to do is to isolate the brand and model of the display from the random data, the same content on the back of the monitor, and then download the latest driver from the random disc or from the Web. These drivers are generally not big, my EMC558 drive compression pack is only 3 K.
When you reopen the Display Properties dialog box, you will notice that the monitor has been correctly identified as the appropriate model. There are many options added to the "Refresh Speed" column! Now you can choose the refresh rate you need!
Sometimes we have the same problem when we upgrade the driver for the video card. The solution is to uninstall the video driver first, reboot the machine, reinstall the latest driver for the video card, and then reinstall the display driver in Device Manager/monitor in System properties.
Second, simple fault handling
1, the screen is not displayed, the front panel's instructions flashing: Check the monitor and the computer signal line connection is firm, and check the signal line of the socket has pins broken, curved.
2, display distortion correction: Today's display is digital control, users can be controlled by the menu to tilt, trapezoidal, linear, amplitude and other corrections. High-grade display can be focused, convergence, color and other corrections.
3, screen and display "signal beyond the Sync range" (for example, the Samsung display, a variety of brands show different content): When the computer issued a signal beyond the display range, the monitor detected abnormal signal to stop working. The user can turn off the monitor, turn it on, and then reset the computer's output frequency.
4, Shutdown Screen Center has a bright spot: should immediately send repair center repair. This phenomenon is due to the display circuit or the picture tube itself caused by the problem, although not at the time to affect the use, but a long, the picture tube burns, the central black spot, then repair, the warranty period has passed, the user's interests are lost.
5, screen display has noise: through the display of the front panel degaussing control function for degaussing, but do not repeat degaussing within half an hour.
6, color type can not be up to 32 bits: Video card problem, check whether the video card has this performance and the driver of the video card is installed.
7, resolution/refresh rate does not go: In most cases is the use of the problem. Check if the driver for the video card and monitor is installed (if provided by the manufacturer), and then check if the video card and monitor can achieve the desired performance according to the instructions. If all is OK, that is monitor malfunction, can only contact repair center to solve.
