In addition, when acquiring a second monitor, you also need to pay attention to the matching upgrade of the graphics card output interface type to match with the new monitor, such as your old monitor DVI interface, but the graphics card has only a D-VI interface and an HDMI interface, then the new monitor must be able to support the HDMI interface, Otherwise you have to buy another transfer device, this will be more trou
Now the computer has become the home of the multimedia center, computers can watch movies, listen to music, play games, surf the internet and so on, now the media resources on the network is very rich, 1080p/720p HD movies are also many, but the size of the computer monitor is small, even in the 24-inch display to see the film, the effect is not very cool, And sitting in front of the monitor for a long time, also very uncomfortable.

You can use CBROM to create one by yourself. For ease of operation, I renamed them old. Bin (wide screen resolution not supported) and new. Bin (wide screen resolution supported ).
