How to make a second monitor out of your phone

How to use a tablet screen as a monitor

Almost any IT-shnik, and, in principle, some ordinary tablet owners dream of using it to their advantage. connecting it to the system unit so that information is displayed on the tablet like on a regular monitor. The first thing that comes to mind is to connect the tablet to the video card using an HDMI. miniHDMI cable, provided that the tablet and graphics card have these connectors.

After all, using an HDMI cable, a digital signal with multimedia data. video, sound, etc. should be transmitted. But the problem is that in a tablet, the HDMI connector is an output, not an input. Those. it can transmit an image to another device (for example, a monitor or TV), but not receive.

However, you should not be upset, because there is good news. You can make the main monitor out of the tablet at the software level. A special program will help the computer recognize the tablet as a monitor. There are three options for how you can use such a “tablet monitor”:

  • Complete replacement for a standard monitor. Can be used in case of emergency, for example, if a normal monitor is broken.
  • The tablet can easily turn into an additional monitor to the main monitor. Everything that happens on the monitor can be duplicated on the tablet display.
  • The tablet screen can become a “continuation” of the main monitor, ie. for example, on a large screen you can watch a movie, and on a tablet screen you can read correspondence, control any computer program with a mouse and keyboard, read mail, and in general, do absolutely everything that you usually do on a PC.

Installation

We need a USB cable to connect the tablet to a PC (or you can connect via Wi-Fi), install the program on the computer, and on the tablet.

  • Install iDisplay on your computer. you can download it for your version of the operating system from the official website for free. Be sure to restart the PC, otherwise the connection will not work.
  • Install the application on a tablet from Google Play. It is paid, and costs 5 bucks (but if you really want to try the application for free, use w3bsit3-dns.com.
  • Launch iDisplay on your computer.
  • We launch the iDisplay application on the tablet. Click on the plus sign to add a “server”, i.e. your PC data (for Wi-Fi connection). For a USB connection, connect the USB cable to your PC and tablet, and click the “USB Connection” button.
  • We are asked to enter IP, port, and name. The IP address and port number can be viewed in the tray by hovering the mouse over the iDisplay. We transfer the data to the tablet. Enter anything for the name.
  • When everything is ready, click “Add and Connect”.
  • Further, if the IP and port are entered correctly, an “iDisplay autorization” window will appear on the computer screen asking if you want to reject the tablet connection, connect once, or automatically connect every time you receive a request from the tablet. I recommend clicking “Always allow”, so this question will no longer pop up, and the connection will be automatic.
  • The monitor will go out for a couple of seconds, blink a little, and calm down. Then the desktop of the computer OS will appear on the tablet.

Customization

This completes the installation, but we need to choose whether the tablet will be the main, backup or additional monitor. To do this, in Windows, go to the display resolution settings (to open the menu. right-click on the desktop).

In front of the words “Multiple Screens”, click on the small triangle. If “Duplicate Screens” is selected, the tablet will repeat the entire contents of the main monitor, almost like a parrot. The Expand Screens option will enable different information to be displayed on two monitors. They will use the same desktop, but they can work independently, complementing each other.

Now comes the fun part. If you would like the tablet to act as the primary monitor, select “Show desktop only 2”, and then click Apply. Then you should open the tray, right-click on the iDisplay icon, select “Settings”, and click on “launch at Windows startup” so that a checkmark appears there.

Now, when you restart the PC and disconnect the normal monitor, when the system boots, the program will automatically start, and you just need to connect to this program through the tablet, and your OS desktop will appear on the screen of your tablet.

In order not to be unfounded, I conducted an experiment, whether the tablet will work as a monitor when I turn off a normal monitor, and recorded the result on video. I went into a text editor, opened a browser, watched the video via YouTube, and went to the Androidtab.ru website, where you are reading this article. I connected to the tablet via Wi-Fi, plus a program for capturing video from the screen was turned on, so it is possible that slight delays in the video will be visible. If you connect via USB, the connection will be more stable and the picture will be faster. Apologies in advance for the video quality (max 480p).

This monitor has a couple of disadvantages. First, to use the tablet screen as a monitor, you must first install the program, and for this you need to see what you are doing. Those. if the monitor breaks down, you need to connect another, working one to the PC, install and configure the program, and only then disconnect the monitor and use the tablet screen instead. The second drawback is that when you start the system, you need to manually start the connection with the PC on the tablet each time. And third, the most important thing is that you need a tablet with a good resolution and a fairly large display. The tablet in the video is a 7-inch, the cheapest Chinese device on the planet with cracked glass. There is very little comfort from using such a “monitor”, but a 9-10 “tablet is much better suited for such purposes.

Advantages: the possibility of touch input from the tablet remains; with a “monitor”, you can lie on the sofa, or go to the kitchen, if the Wi-Fi signal is enough, and use your computer.

Cable or WI-FI?

For an emergency expansion of the working surface, you can use a tablet, if it is not there, then even a smartphone will do. In addition to this, the device also needs the correct software.

Splashtop’s free Wired XDisplay software does the job just fine. You will also need a wired connection to your computer. best with a USB cable and a USB 3.0 port (USB 2.0 can be used).

It is also possible to establish a wireless connection using programs such as Spacedesk or iDisplay. But the first program does not always work stably, and the second is paid, so it is better to make the choice in favor of the cable.

How to make a second monitor from a smartphone or tablet?

After pre-installing the software on a tablet and laptop or personal computer (an agent is needed on the computer. Wired XDisplay Agent), you need to launch both applications.

Now it is enough to connect the equipment. It should also be borne in mind that the software will boot the computer, so with a processor like Intel Atom, you might run into a performance issue. This can be eliminated by setting the quality and performance by choosing low.

How the second screen works?

After that, you can start working. The device should work in the same way as a standard monitor, but the quality and number of FPS may decrease.

This particular software has some limitations. First, you need to use a USB cable and access a USB 3.0 port. At the same time, not everyone wants to install an additional cable, and there is not always a free port. But the quality depends on it. The second is the session time limit. In the free version of XDisplay, a session lasts up to 10 minutes, after which the program shuts down and must be restarted. Of course, this is annoying and can scare you away from working with her.

Is it worth?

If you urgently need an additional screen, then you can safely use this solution. It should be borne in mind that tablets have small screens, so the work surface will also be small. As noted, you can also use a smartphone for this, but the screen there is even smaller and the work will not be comfortable enough.

Despite all the stated disadvantages, this is a real way to cheaply and quickly increase the work surface. The software is free, and most users have a tablet or smartphone, as well as a USB cable to connect devices to a computer. It should be noted that the Wired XDisplay program is available for both the Android and Apple platforms, but users of tablets with Windows installed will not be able to use it.
