Two laptops screen sharing, how to share the screen between two laptops

You can't do this, although the current notebook supports three displays at the same time, but these three displays can only be achieved by independent displays in addition to the notebook itself. Your other two monitors are also connected to the laptop's main unit, and this signal can't pass through the other two laptops.

The host is passed to it on the display. Because the other two old notebook consoles only have the function of signal output, but do not have the function of receiving signal input. However, there are ways to modify, but it will cost some money and waste the other two laptops, you measure.

Method: Remove the old laptop screen, and then take it to the electronic city to find a business with an LCD screen circuit board (I have a special LCD screen circuit board here in Shenzhen, a complete set of them, including: the screen of the motherboard about 25 yuan, high voltage bar 11 yuan, VGA cable.

The connection cable from the motherboard to the screen, the connection cable from the motherboard to the high-voltage bar, the connection cable from the screen to the high-voltage bar, a full set of more than 50 yuan), find this merchant and give him your screen and let him give you the board driver, they will test OK before charging you money. If you still want to use the shell, there is a special place for the shell, and there is a more important thing in the place with the shell, the panel control switch of the display. The full set of shells costs more than 30 yuan (mainly depending on the size of the screen).

In addition, you have to be able to install it yourself, and it is not difficult to find someone else to install it for 30 yuan. If the configuration of your two old laptops is okay and all of them are good, it is recommended that you sell these two old laptops, and then use the money to buy a new display screen is more convenient.

There is a screen expansion there to adjust the resolution, and it should be able to expand by linking the two computers with a VGA cable.

The win7 system has an expansion function, which is a laptop to connect two monitors.

It enables a host to provide 1-7 users at the same time, synchronously and independently realize various basic operations and functions of the computer, and each user has the same use function as a single machine, so it is recommended to buy a multi-** sharer system

Interactive meetings with the screen sharing software TurboMeeting can be implemented clearly and smoothly.

Generally, the display has more than two input sockets, and there is a signal source selection in the menu, and many monitors are also set up with shortcut keys for signal source selection, and you can switch different inputs by pressing it directly on the display. Specifically, there are three steps:

1. First, let the two computers enter the multi-screen mode:

In a random empty space on the desktop, right-click and select Screen Resolution. You'll see the on-screen setup options, if you have two monitors installed, as shown below. If you don't see both displays, you can click "Detect" to detect them.

Then, in the options for "Multiple Displays", you'll see that there are two options: "Duplicate these displays" and "Expand these displays".

2. If you select "Copy these displays":

You'll see the exact same Windows window on both monitors, which is generally more suitable for teaching presentations, venues for displaying the same content for multiple people, and commercial displays such as venues and outdoors.

3. Select "Expand these displays".

Extended mode means that the content of one display is extended to two displays, and the content is displayed continuously and differently, and we can define the horizontal or vertical addition. This state is more suitable for audio editing, editing, graphic design and other software and functions that require more delicate effects. Of course, it is also very suitable if you are a gamer or someone who needs to run multiple programs, and even more displays can use this method.
