The DELL book that was purchased at the end of 2008 has now been over 8 years old. From the very beginning, the computer was turned on every day and it was not until the dormitory turned off and the battery was shut down. It was not open for a few days now. The computer still has to watch cartoons. Without the just-needed, there is no power for replacement.

Some time ago, the screen would occasionally appear with a black screen. At this time, it was only necessary to use the simplest and most effective method of repairing household appliances. It was OK to beat a few times until a few days ago. No matter what position you use, you are always indifferent. Disassembled the line to check the line, did not check out any problems, I thought, probably the big period soon collapsed, but listening to the sound of the fan, it should be able to still work properly, but the screen does not work so I think it should be able to Rescue it. Because the book can only output VGA signal, there is no VGA line in the home, so he took the unit and tried it.

The happily came home with a VGA cable. After picking up the computer, he dug his buttocks and looked for it for a long time behind the TV. An ominous hunch slowly spread his heart and quickly flipped through his TV bills. There is really no VGA interface. Then give up here? No, no, this is not my style. I remember that one thing could expand the interface, search and search, called Express, but unfortunately there is no way to expand into HDMI. Instead, look at the transfer line, but found a large Some of them are HDMI to VGA. Just when I want to doubt the life, VGA to HDMI line is quietly appearing in my world.

Some other small manufacturers' patch cords not only need USB power supply, but also need to connect 3.5mm audio separately. This is too cumbersome. Therefore, the switchboards of the superior and the Green Alliance are screened out. They are USB audio + power supply, convenient and concise. . I chose the superior ones because the two are functionally consistent. The line length of the superior is 14cm, while the green line is 50cm. Personally I think that the longer the wire, the more it increases the degree of disorder. It is not as refreshing as the shorter ones.

Out of the box, no matter what, there is only one switch cable.

Divide two lines from the converter, one VGA and one USB,

Interfaces are brilliant flash, USB also posted a layer of film, or more attention to detail, to give extra points.

On the back is the nameplate, VGA to HDMI Adapter with Audio, with audio oh

It's also very easy to use, this is connected to the computer's VGA and USB,

The other side is connected to HDMI and then connected to the TV. At this time, the computer automatically recognizes that there is a picture on the TV. Only the resolution is not necessarily appropriate. After the resolution is set in the system, the computer content can be displayed on the TV. Audio only needs to select the USB output.

Only a set of wireless mouse and keyboard is missing, so that it can be tanned on the sofa.

But after all, it is converted from the analog signal, the first VGA output to the big screen will have water ripples and other issues, although the analog signal is converted to digital signals, but also not reach the effect of high-definition

After taking a photo, you can see that the font is thick and thin, because it was generated after the conversion.

Look at the test picture again, it can be clearly seen that the stripes are unevenly distributed.

to sum up:

The book was successful in the rescue operation, but later life will have to be abandoned.
