How to connect a second monitor via USB?
When working at a computer, a second monitor is sometimes required. But there are times when the required D-Sub (VGA) or DisplayPort output is available in the computer. For example, it may not be in the candy bar, as it happened in my case.
Naturally, many are wondering if it is possible to connect a monitor via USB?
As it turned out, there are a variety of USB adapters on sale with an output to VGA / HDMI / DVI or combined. In addition, there are adapters that only work with USB2.0, and there are adapters that support both USB3.0 and the outdated USB2.0.
After a short search, I settled on USB adapters based on DisplayLink technology.
The essence of such a USB adapter is as follows. A program and driver (in this case, DisplayLink Manager) is installed on the computer, which has access to the resources of the central processing unit (CPU) and the card (GPU).
The stream to the second monitor is compressed and transmitted via USB to a decompressor, a specialized microcircuit that is built into the adapter itself. This microcircuit performs decompression of the signal received via USB and displays the picture on another monitor.
As you can see, this uses the CPU resources of the computer itself, which compresses the signal. However, it can be quite heavily loaded. If the picture on the extended monitor is NOT updated, then no compression and processor load occurs, since the control program constantly monitors changes on the screen.
The USB adapter itself is powered via the USB bus (5V) and does not require an external power supply, which is very convenient.
On the official DisplayLink website in the “Products using DisplayLink Technology” section, you can see the list of manufactured devices. Among others, there are USB adapters and USB monitors.
The range of manufactured USB adapters is quite extensive. Basically, devices differ in the supported type of USB interface (2.0 / 3.0) and the maximum allowable resolution of the output image. Typically, USB2.0 devices support up to Full HD (1920 x 1080) resolution, while USB3.0 devices can display up to 4K (3840 x 2160) resolution.
To work with my monoblock, I bought a PLUGABLE UGA-165 USB adapter, or rather, a copy of it.
As it turned out, an exact copy of the PLUGABLE UGA-165 model is being sold on Aliexpress for a fairly low price. He took it. Here’s what’s included.
This is the so-called Single Display Adapter, that is, an adapter for one monitor. There are adapters for two, three monitors and a full-fledged docking station, to which you can connect several additional high-resolution monitors.
I chose the right adapter quite carefully. It was required that it work via the USB2.0 interface and have different types of VGA / HDMI / DVI outputs. This would allow, on occasion, to connect any monitor or LCD TV.
In addition, I really wanted to get a picture on the screen with the highest possible resolution (HD Ready, or better Full HD).
The set included two additional adapters for a standard 15-pin VGA connector (aka D-SUB) and HDMI. This will allow the adapter to be used in conjunction with new LCD TVs and monitors, which are increasingly equipped with an HDMI input.
For completeness, I will show a photo of the insides of the adapter.
Here is a printed circuit board with not many elements.

DisplayLink Manager software
All control of the USB adapter is carried out through a special program. Displaylink Manager.
Its latest version can be downloaded from the official DisplayLink website at the link. In addition to Microsoft Windows, MacOS, Android, Ubuntu and Chromebook operating systems are supported.
I have Windows 7, so I chose this system. Before downloading, you need to be named by the “Accept” button to confirm your agreement with the license agreement. After that, the download should start. Run the installation of the downloaded file with a double click.
During installation, the program will ask you to connect the USB adapter to your computer.
In Windows Device Manager, the USB adapter appears as USB Display Adapters (USB-DVI).
After installing DisplayLink Manager, its icon will appear in the tray. Here is such.
Using this program, you can control the USB adapter: turn it on, off, change the resolution to additional. Monitor, rotate the screen, expand the screen on different sides. There are quite a lot of settings.
I will tell you about some features of the DisplayLink Manager utility that can be useful.
By default, DisplayLink Manager launches when the computer is turned on. This is convenient as the desktop immediately expands to an additional monitor.
But, there are times when an additional monitor is not needed for operation. Then it can be turned off.
To disable the additional monitor, left-click on the DisplayLink Manager icon in the tray. In this case, the program menu should appear.
Select item 2.USB-DVI. “Disable”. In this case, the monitors briefly blink, and the indicator on the USB-DVI adapter will go out.
This will disconnect the USB adapter and enter sleep mode on the add-on monitor. For me, for example, the second monitor of the BenQ FP93G brand went to the duty room with a slight delay, but, as I understand it, it depends on the monitor itself. Dell monitor P2217h went to duty immediately after disconnecting the adapter.
To turn on the additional monitor again Do the same operation as when turning off the monitor, but this time select the “Extend” option. This.
In this case, the main screen will briefly blink, and the indicator on the USB-DVI adapter will light up. The desktop will again be extended to an additional monitor.
If necessary, you can expand the desktop to the case / left, as well as from above or below the main one. For example, I have a desktop extended case, but someone might need a different configuration.
If you expand the desktop from above or below the main one, then you may encounter this. Move the mouse to add. The monitor will be possible only within the border of the width of the second monitor. For example, the width in pixels of the main monitor is 1920 pixels, and the second is 1024.
In this case, if you move the mouse to the top / bottom edge within 1024 pixels, then you can easily move the mouse cursor to the second monitor. If you enter the mouse pointer further than 1024 pixels, then it will NOT work to move it to the second monitor. Such is the feature.
For those who have a monitor that allows you to change the position of the screen, the option “Screen rotation” may be useful.
When changing the screen orientation from landscape to portrait, SIMply select the “Screen Rotation” item in the DisplayLink Manager menu and then one of four options to choose from.
You can return the image to the right or to the left. Turning step 90 0.
If you select “flip”, then the image on the monitor screen will be displayed “upside down”. When you select “Standard Album”, the image on the screen will take a standard form, which is the default.
On the second tab of the menu there is an item “Screen resolution”. Through it you can set the screen resolution of the second monitor. Usually the program independently determines the nominal resolution of the additional monitor, but, if required, it can be set manually. It was detected automatically for me. No additional action required.
If you select Use this monitor as primary, the secondary monitor becomes the primary. The taskbar will appear on its screen. This can be useful if the secondary monitor has a higher resolution and you work primarily within the boundaries of its screen.
The item “Create a copy” duplicates the image of the main screen on the second monitor. What I didn’t like about this mode is that the image resolution on both screens gets smaller, and its proportions and positioning on the screen change.
Apparently, this mode is used in conjunction with projectors. I don’t need him.
The item “By screen TV” can be useful in cases where the USB adapter is used in conjunction with an LCD TV. In some cases, even when the adapter works correctly with the TV, there are black margins on its screen at the edges. You can correct the position by adjusting the image manually.
To do this, select the “By TV screen” item and adjust the image on the TV screen so that it occupies the entire screen.
A red frame appears on the LCD TV screen, the edges of which can be shifted using the “” and “-” buttons in the “By TV Screen” window. Configure and click the “Apply” button.
There are two items in the main DisplayLink Manager menu: “Sound Setting” and “Advanced Configuration”.
When you click on the “Sound Settings” item, the standard Windows “Sound” settings window opens, which is available on the “Control Panel” path. “Sound”.
The fact is that some USB adapters also support the transmission of an audio signal, for example, via HDMI. Therefore, the program has a sound setting item.
The situation is SIMilar with the item “Advanced configuration”, which SIMply refers to the tab of system settings Windows screen resolution (“Control Panel”. “All Control Panel Items”. “Screen”.
You can find out the version of DisplayLink Manager by clicking on “DisplayLink Manager” at the top of the main menu.
If there is a new version of the program, it is better to download and install it, since errors in newer versions can be eliminated.
During the operation of the USB adapter, some of them came to light. It is very rare for a driver to fail. Solved by reboot. Sometimes this is not required, the driver restores its work automatically.
Another “glitch”, which was revealed when using the adapter, is the hang of the program, the window of which was on the additional screen. Monitor. Hangs occur when disconnecting USB adapter via DisplayLink Manager menu.
Basically, this is how the Media Player Classic freezes during playback. Perhaps this is a feature of the player itself. It was solved by forced closing Media Player Classic and restarting it.
Points to consider when choosing a USB adapter?
First, you need to know which version of USB (2.0 or 3.0 / 2.0) the adapter will work with. For example, my monoblock SIMply has USB3.0 connectors, so I chose an adapter that supports an older version of the interface (USB2.0).
If your computer has a modern USB3.0 connector, then it is better to take an adapter with USB3.0 support. Some of the USB adapters support both USB3.0 and USB2.0 interface versions. But here it is worth understanding that the bandwidth of the USB2.0 interface is low, and it will not be able to display a picture with a resolution higher than Full HD (1920 x 1080) on the monitor. This is the “ceiling” for him.
Another thing is USB3.0, the bandwidth of which is enough for multiple monitors with high resolution.
The second thing to consider is what kind of connector will be in the USB adapter. If standard VGA is enough for you, then you can get the cheapest adapter. Newer monitors support the newer HDMI and DisplayPort interfaces. Therefore, you should think ahead and take something newer. Or such an adapter, which is equipped with all these connectors, as in my case.
The third thing to consider is that USB transfer technology uses up the resources of the central processing unit (CPU) to compress the image. At the same time, it is quite heavily loaded.
If you have a weak processor based computer Atom or Celeron, then, perhaps, you will face the fact that with a dynamically changing picture on the second monitor, the computer will “freeze”, since it may not have enough resources.
Here is a screenshot for an example. Loading the processor Intel Core2 Quad Q8400 (2.6GHz) of my candy bar when outputting to the second monitor of the player, which plays a movie with a resolution of 1920 x 1080 (Full HD). As you can see, the load is at least 14
fifteen%. This is provided that other processes on the computer are NOT running.
If you move the player window to the screen of the main monitor, then the load on the processor drops sharply and remains at level 3
It is also worth remembering one feature. If the picture on the second monitor is static, that is, it does not change, then there will be NO load on the computer processor. The image is SIMply displayed on the second monitor from the memory of the USB adapter itself.
And one more important thing to know about. Inexpensive adapters based on old processors are only suitable for transferring mostly static and little-changing images. They are not suitable for dynamic games!
Even when playing high-quality Full HD, the computer starts to slow down. Therefore, with a higher resolution and bit rate, it is better to view it on the main monitor, and use the second one to display small-changing images. For example, use a second monitor for surfing the Internet, viewing documents, etc.
Despite all the advantages, the UGA-165 USB adapter upset me at first.
After unpacking, I decided to try it out in conjunction with an LCD TV Samsung LE32A430T1. But the TV did not “see” the signal from the adapter point-blank and I did not manage to display the picture on it. I tried everything. I connected both via VGA and HDMI, climbed into the TV settings, changed the resolution. Nothing helped.
To calm down, he explained this stubborn reluctance of the LCD TV to work with a USB adapter only by the fact that it is already quite old. In addition, in the instructions for the TV, I found a clarification that it does not support SOC synchronization or something like that. Perhaps the reason lies precisely in this.
How to connect a computer to a TV via USB?
There are situations when the computer has an output with sound via HDMI. Or do you have an Apple laptop from one of the previous generations? Also, this problem is inherent in monoblock PCs, where a SIMple interface for a TV or a second monitor, alas, is often absent. This is where USB comes in. Universal computer interface, which any PC is endowed with in abundance. You can connect to it like mice, flash drives, printers, cameras and other peripherals, and TVs, projectors, monitors, which, in fact, will be discussed below.
Advice: If your computer or mobile device has free or no ports for connecting the screen, and there is no USB. It doesn’t matter, you can “enter” through the “back door”.
Let’s make a reservation right away that the article is designed for the most common USB standard today. 2.0, in turn, this will work for USB3.0 as well, but will not work for USB version 1. Here are the connectors that should be on a candy bar or laptop to connect the screen via USB:
Let’s consider two possible solutions: wired and wireless. Both work according to the same principle: a program is installed in the system that creates a virtual card and a sound card, and then output with sound from THESE devices is made via a universal USB bus to a device that can decode these signals.
A wired solution is a module that connects with a wire to a computer and, on the other hand, connects to a TV, projector or monitor, as well as audio speakers or headphones. Windows, Mac, Linux and even some Android systems automatically recognize the device and install drivers on it. You can also force the driver to be installed from the manufacturer’s website, such as DisplayLink. You can view and select a suitable adapter here.
If you are a fan of gadgets and are ready to transfer only files to TV, which he can play on his own from a USB flash drive connected to it, then it is impossible not to mention the Exotic solution, a USB-USB wire with a special controller. It SIMulates a USB flash drive for TV on the one hand, on the other hand, it is connected to a computer and “set” on the folder of your choice from the media files. Thus, the TV “sees” these files as if on a connected USB flash drive, although in reality this is not the case. The decision is rather controversial, especially in the list of supported operating systems at the moment only Windows, and then, the “shaggy” version. If you are interested in such a “miracle of technology”, write in the comments, we have it.
Wireless solutions use a unique USB wireless standard, a broadband radio interface that is completely transparent to the computer. Here our exclusive product U-140A takes a monopoly position. Compact, easy to install and fast-acting kit, its tiny transmitter connects to your computer and is virtually invisible in it:
Both desktops, laptops and mobile devices are supported! The receiving part is connected to a monitor, TV or projector in any way, via HDMI and / or VGA, the sound is output both to HDMI and to the minijack speaker / headphone jack. This is wireless mode. But the device can also work in wired mode. Just connect the receiver to your computer directly and WOOA-LA! A kind of universal combine for all types of connection:
The performance of the device is at the level: excellent “pulls” FullHD resolution, works without delays, is resistant to interference.
The assembly is carried out in South Korea, so you can be triple peace of mind about the quality. information about the U-140A can be found on its page and also from the review:

Software installation methods
In order for the operating system to know how to work correctly with the new equipment connected to it, a set of special instructions. drivers. is required. They are unique for each device. Sometimes developers can use one common driver for several devices.
Thus, a driver is a kind of adapter with which the system controls the device. Software refers to both drivers and additional software. Typically, it serves to facilitate the user, calibrate, configure and test the device. You can use the device without drivers (as a forced temporary measure) before the disc is found or the drivers are downloaded. Consider connection methods with and without drivers.

How to connect a printer to a laptop on Windows 7
Operating systems of the Windows family are very widespread among users. It was the ease of installation and handling of the system that greatly influenced this. The same goes for the printer. Very often, when you connect it, the drivers can “pick up” themselves and the device will be immediately ready for use.
Windows 7 desktop
If the automatic setup failed, then insert the disc and Install from it. If it is not there, then you need to go to “Devices and Printers”. This item in Windows 7 can be located directly in the “Start” menu. At the top of the window that opens, there should be a button “Install”. After clicking on it, a new dialog will appear, which will offer you to select the type of connection. If you need to do this using USB, then select local, if other methods. the second item. Next, you need to either select a model known to the system from the list, or install from Windows Update. The second method rarely helps, so we select a ready-made driver from the list. Then we write the name of the device, if necessary, select the network access. This completes the installation.
Installation on MacOS
On almost all versions of macOS, this process is the same. First, we physically connect both devices with a USB cable. You will also need drivers to work properly. You can download them on the official website of the manufacturer or from the disc included. Although software for Mac on printer disks is quite rare.
Then in the Dock you need to find “System Preferences”. Then go to “Printers and Scanners”. In the new window, click on the “plus” to add and select your device from the list.
How to connect an HP printer to a laptop
A large number of HP devices can be installed using the drivers built into Windows 7, 8, 10. For example, for Windows 10, you can follow a few SIMple steps:
- In the search, you need to drive in the phrase “Change device installation parameters” and click on the result.
- In the window you need to specify “Automatic” and save.
- Connect printer to computer.
- Go to “Devices and Printers”.
- Click “Add Printer”.
- Select your model in the list and click “Next”.
- The device should be successfully installed.
How to install on Ubuntu
This is probably the most interesting connection. It is worth starting long before buying a printer, since Ubuntu does not support all devices. You will need to make sure on the manufacturer’s website if there are drivers for a specific device for Ubuntu. Then you need to additionally look for information about successful launches in second users.
After you have made sure that everything you need is available, you need to find instructions on how to install a specific brand, since the methods and options are different. In one, you will have to change the configuration files, in the other, you just need to install a couple of applications from the repository.
