How to make a touch screen on a TV
Connecting and disconnecting the touchpad on laptops
If you are convinced that your device has this function, you can start connecting.
Important! Usually, information is given in the instructions and manuals that come with the purchased equipment.
How the touchscreen works on a laptop
For a start, it will be useful to know how this technology works in modern devices. The basic principle of operation is the recognition of hand touches of the display on the monitor. The technique recognizes the signal transmitted from the fingers to the internal elements of the microcircuits to process and convert the incoming command. After that, the signal is converted into a specific action that the user sees on his screen.
Various components and programs are involved in this process. They instantly process the received commands and activate a specific action.
The advantage of a sensor on a laptop
Until recently, all models were equipped with a standard monitor for displaying images. And all the control actions the user had to carry out using the keyboard and mouse.
The sensor function has been added relatively recently. But it immediately became popular with users. This control method provides convenience and comfort during operation, and also makes it easy to navigate the system interface.
In our article we will talk about how to connect this option on a laptop.
IMPORTANT! Enabling and disabling the touch function is only possible if the equipment is equipped with this feature. Check the information in advance on the manufacturer’s website or ask the sellers.
How to enable touchscreen on laptop
The rapid development of modern technology allows manufacturers to improve their equipment and add various features. Everyone already knows about touch screens in various devices. They are actively used in phones, tablets, in the displays of some cameras Now the developers have come up with a version of the touch screen for laptops.
Algorithm of action
If the documentation was not found or you have lost it, use the following action plan to activate the sensor.
- Activate the operation of the equipment in the standard user mode, wait until all components are loaded.
- Enter the main menu of the system by pressing the “start” key.
- After that, in the list provided, select the “control panel” section, go to it.
- In the drop-down list of sections go to the “pen and touch input” item. Select your finger as your primary tool among the options for controlling actions on the display.
- Now all that remains is to calibrate the sensitivity and display position for better interaction.
After these manipulations, you will be able to perform various actions and commands with a simple touch with your hand. If necessary, you can further adjust the display settings and input method for ease of use.
In different operating systems, due to the differences in the interface, it can be difficult to find the path to the desired section of the settings.
Important! For quick orientation, use the search bar in the “Start” section or ask the assistant to “run” using Win or the WinR keyboard shortcut.
Now you know how to enable the touchpad on your laptop. This will make it more convenient to use.
Test pictures for each parameter
Used to fit a single parameter. After setting this parameter, you will need to switch to another picture and adjust another parameter.
Test pictures with multiple test zones
They are used when you need to set up quickly or when the setting is done by an inexperienced user. On such images, you can configure five basic parameters at once.
Color saturation and color temperature adjustments are made based on human skin tone. In order to get the correct color settings, you need a test picture with women depicted on it. They have different skin colors, adjust the controls so that the skin looks natural. To do this, use the remote control keys to move the color parameter slider in the menu until all faces look natural.
Do you need to customize the screen? Hasn’t the manufacturer taken care of this?
This is partly true. Large production volumes do not allow the manufacturer to fine-tune the screen, be it Samsung, LG, Sony, Toshiba, Sharp.
about test images
Each picture taken separately serves to adjust one parameter. The test from Burosch contains:
- Pictures for adjusting five basic parameters: format, brightness, contrast, color and focus.
- Pictures with test zones for simultaneous setting of several parameters
- Pictures for professional calibration
- Several real pictures for checking
Correct brightness adjustment is achieved when all grayscale is clearly visible against a black background. To do this, use the remote control keys to move the brightness parameter slider in the menu until all gray shades are visible.
Getting started setting up the screen
First of all, you will need to select the signal source on the remote.
To do this, press the Source or Input key and select the image source: USB flash drive (or the corresponding HDMI input if you are broadcasting from a PC / laptop).
Next, you need to enter the TV menu: to do this, press the menu button on the remote control and go to the picture settings. Different manufacturers have different names for the menu button: it can be Settings, Options, Menu. The picture below shows the most common remotes.
If you have any difficulties with entering the menu. in the instructions for the TV, you can find a description of this procedure more precisely, specifically for your model. When you enter the menu, you will see something like the following:
Next, you have to choose which way to go: take a universal picture (faster) or adjust each parameter according to the corresponding picture (better).

Is there a difference in TV screen expansion of different brands
There is not much difference between TV brands in terms of image expansion options. But some models may have more functions. For example, Sony has slightly more options than Fhilips and Samsung.
It also depends on the year of manufacture. A newer model of any brand is always improved, so there will be more options in its functionality than in an outdated device. As a rule, all manufacturers adhere to a standard set of options.
How to expand the screen on a TV
It happens that the image on the screen has flaws, sometimes too compressed, sometimes stretched. Sometimes the frames are very small, and sometimes they simply do not fit into the monitor. This flaw has its own reasons.
Change the aspect ratio of the set-top box
How do I expand the screen on my TV? You can also program the frame format through a set-top box. To do this, go to the Menu, select “Settings”, find “Screen”. The following options are found here:
- changing the screen resolution (screen rezolution);
- change of positions of the monitor (screen position);
- rotation (screen rotation);
- change of screensaver;
- enable, disable HDR.
What opportunities and tools to use to expand the monitor is up to the viewer himself. If someone is not familiar with the operation of the remote control, you can ask your friends, acquaintances or neighbors. Information posted on web resources is also useful. The necessary knowledge and some skills will help to cope with the problems that arise while watching TV.
Disable via BIOS
Any hardware device connected to the laptop can be disabled in the BIOS. Including the display. An important point is that it is better for inexperienced users not to use the BIOS for configuration, because an incorrect request can damage information on a laptop or completely delete the operating system.
But if the user is confident in their capabilities, then you can proceed to disabling the touch screen. First you need to get into the BIOS itself. On many laptops, this can be done by holding down the F1 or F2 key while turning it on. It can also be another F key on the keyboard. Everything depends on the model. On Lenovo laptops, a special key is provided for this at all, located at the charging slot.
After logging in, you need to move to the “Advanced” tab. In it, select the “System Properties” tab, and then “Mouse / Keyboard features” and then go to the “Internal Poiting Device” tab. There will be an item “Disable”, which must be selected and activated with the Enter key. That’s it, the touch screen will be disabled, and now you can exit the BIOS, having previously saved all the settings. This can be done using the Esc key and following the prompts on the laptop screen.
Disable keyboard shortcut
As a rule, this is the Fn key and one of the F keys. To find it clearly, you will have to study the instructions for the laptop or find a special icon on one of the buttons. Possible options: F1, F2, F3, F5.
No buttons have a dedicated icon? Then it is worth checking the combination of the Ctrl and Shift keys with other keys on the computer. Sometimes the manufacturer uses numeric keypad elements in combination.
Disconnect via task manager
An equally simple way to manage the state of the touchscreen is to use the task manager.
First you need to call the task manager. On all versions of the Windows operating system, this can be done with the Ctrl-Alt-Delete keyboard shortcut. After simultaneously holding down this key combination, a task window will pop up on the screen. In it you need to find a program that is responsible for controlling the screen sensor. Depending on the laptop model. The program can be named in different ways. Most often it is all the same Synaptics.
As soon as the program is found in the manager, you need to click on it with the left mouse button and click on the “end process” button. The performed operation will completely disable the touch screen until the next restart of the laptop.
Disable the touchscreen on a laptop in different ways
In the age of high technology, you will not surprise anyone with a laptop with a touch screen. Almost everyone can buy a similar device for their office or home.
Often a touchscreen is not needed at all. Therefore, it becomes necessary to disable it. And, oddly enough, not everyone knows how to properly disable the touchscreen on a laptop. In practice, this turns out to be no more difficult than, for example, unlocking a smartphone.
Disable by the program
The Windows operating system provides a special utility that involves managing the sensor.
It is called Synaptycs. This program has already been launched by default on laptops with a touchscreen. You can find it in the list of programs or by right-clicking on the touchpad icon located in the taskbar in the lower right corner.
Another way to programmatically turn off is to use the Start button. This method is relevant only for the Windows operating system with an update of at least version 10. The method works like this: you need to go through the path “Start-Settings-Devices”, find the “Touch Panel” tab, where the “Advanced Settings” tab will be located. It is this tab that is used to control the touchscreen display. Any screen setting can be made in it. Including disabling the touchscreen.
Depending on the operating system, the path to the settings panel can be completely different:
- Windows 8: Start-Settings-Computer and Devices-Mouse & Touchpad
- Windows 7: Start-Control Panel-Hardware and Sound-Mouse
In version 7, oddly enough, sensor control is located in the mouse control tab. But it is in it that it is much easier to turn on or off the touch screen than in newer versions of the operating system.
Disconnect via device manager
Through the device manager, you can manage any programs on your computer. But in order not to accidentally disable something important, you need to have the proper level of PC use. It is better for beginners not to use this method.
The device manager is invoked using the WinR or WinPause keyboard shortcut. In the first case, in the “Run” field, enter the devmgmt.mc command. In the second case, you will need to select “Device Manager” in the “System” item.
Next, in the device manager, you need to find the “Mice and other devices” tab. Opening it, the bottom will be a device with the letters HID. This device must be turned off. If there are several such devices, then you need to turn off everything. This device is the laptop’s touch screen.
You can turn the touchscreen back on by performing all the above manipulations and turning the devices back on.
A simple and affordable way to turn off is to use a key or a combination of them on the keyboard. Typically, the laptop manufacturer marks these keys with special identifying symbols, and places them at the top of the keyboard.
An example of a touch screen off button on a laptop
One touch of a button is enough to deactivate the touch screen. But this only works on licensed devices.
Important! The manufacturer posts detailed information on the rules of operation on its website. Perhaps there will be information on the keys to disable the touch screen.
Disconnection using third-party programs
The best of them are available for a fee only. But there is a very good and at the same time free utility called TouchPad Blocker. The program is made in English, but at the same time anyone can understand it.
It has many useful features. For example, periodically turning on / off the touchscreen for a specified time limit, soundtrack for pressing the touchscreen, and much more. The utility will be very useful for those who want to fully control touch screens from one program.
Even if the user accidentally turns on / off the wrong thing, the usual removal of the program from the computer will help. After this process, the touchscreen will continue to work as usual.
As you can see, turning the touchscreen on or off on a laptop is not difficult at all. If one method does not help, then you can always use another, more suitable for a particular situation. The main thing is to clearly follow the instructions outlined above.
