Monitor test, after going to be patient, slowly detect, mainly to see if there are bright spots, dark spots, color spots, and strive to buy a perfect screen.. LCD now has not much technical content, a lot of small counter owners can get some foreign garbage or scrap LCD, and then dismantle the corresponding LCD, re make a drive IC circuit board and power supply module, and then find a corresponding shell can re assemble a LCD.. However, there is no guarantee of the quality of such a monitor, because the LCD screen is not likely to be new, so I don't know when it will suddenly hang up. Although it's cheap, I'm worried all day long with it. All I can do is pray that it won't be broken.. If it breaks down within a year, will he replace it for you? It is estimated that this kind of monitor or repair goods, this kind of machine with the least quality assurance, I suggest not to buy it. Now the LCD is so cheap, there is no need to save that money.. There are many aspects, such as brightness, contrast, panel type, response time (now the mainstream LCD has basically no such problems) and so on.. There are special tools to check the bad points. You can also adjust the brightness and contrast of the monitor to moderate, and observe more solid color full screen pictures (such as red, yellow, blue, green, etc., it's better to try more), to see if there are any mottled spots..
