How to connect a second monitor to a PC with an HDMI to HDMI cable and how to connect it to smartphones and tablets with an HDMI to USB / C cable or with an adapter
Using an additional monitor can be useful in many circumstances. It can be connected to a computer to view the screen over a larger area, but it can also be used for enlarge the same screen.
In addition, with the appropriate cables and adapters, a monitor can also be connected. Board and there smartphone to display the relevant screens. In this post we will see how to proceed with the connection, how to choose the computer settings and how to choose the sound output device. Monitors usually also have
built-in speakers to play the audio, but if they're not there, you can buy and connect.
The monitors are all equipped with a port hdmi to be connected with a special cable to the corresponding port hdmi computer windows. Mobile devices don't have ports hdmi but they only have one door usb from
Type C which is to charge the battery, to transfer files to a
pen drive
and for other features.
However, not all mobile devices are supported to project your screen on another device. It's not really clear why some high-end products aren't. The discriminant seems to be there
software version of the device and the presence or absence of a particular technology. I could test this with android 9 the screen is not projected while with android 11 there are no problems in that regard.
The technology needed for screen mirroring is called MHL that means
Mobile high definition link. It's a pattern of
2010 that allows the
video signal transmission by the door
usb. This standard supports resolutions up to
2160p (Ultra HD or 4K). The problem is that often the presence or absence of this technology
not included in the technical data sheets from
smartphone AND Board.
posted on my
Youtube channel
a tutorial in which I illustrate how
connect monitor to pc and mobile phone.
To get an idea of the prices of monitors on the market, I list someone found on amazon:
- Lenovo Q24i
1920x1080, 23.8" HDMI + VGA at the cost of
€ 169,00; - Samsung CF39 monitor, 24″, 1920×1080 (Full HD), HDMI, D-Sub, Audio In at the cost of € 141,07;
- Monitor LG 24ML600S
24", 1920 x 1080, 10W stereo audio, HDMI, audio out at the cost of 149,99€; - Acer KG241YAbii 24" monitor, HDMI cable included at the cost of
139,90€.
Some monitors beyond the door hdmithey also have an old door VGA alternative that still offers inferior performance. If your monitor doesn't have audio output, you can connect external speakers like these:
- Trust in Leto
2.0 speaker set at the cost of 9,90€.
who wants to connect PC to monitor also need a cable
hdmi to hdmi if it was not included in the monitor:
Instead of connect the monitor to the mobile device you need a cable like this:
Finally, who already had the cable hdmi to hdmimaybe supplied with the monitor, to connect it to the mobile device you need a adapter with a female port of hdmi
and a male of USB Type-C like the following:
- TSUPY USB C to HDMI Adapter
4K at the cost of 9,99€; - USB Type C to HDMI Adapter, Up to 4Kat the cost of 13,99€.
CONNECT THE MONITOR TO THE WINDOWS PC
After connecting the computer to the monitor with the cable
hdmi to hdmi
and having turned on the monitor you go up Definitions.
Inside System -> Screen the new monitor will be detected. The computer will be indicated with the number 1 while the monitor added with the number 2. If we weren't sure, let's go to the button Identify.
then i will show up identification numbers on their respective screens. Click on the menu on the right.
There are four possible choices. With Duplicate these screens
you will see the same screen on both devices. With
Show only in 1 and with Show only in 2 the screen will only be shown on one device.
The most interesting choice is extend these screens. With this option,
if you move the mouse to the right, it will disappear from the computer screen to appear from the left on the monitor screen. With this solution we can also
drag windows from computer screen to monitor screen and vice versa.
When switching from one option to another
let's go black for a few seconds then
see a message self to maintain
The Definitions or to restore the previous ones with a time of 15 seconds to choose.
I remember that instead of a monitor you can use it
another computer screen
per
project the screen
the first and opt for one of the same four options. To project the screen of a computer the application starts
To connect.
VIEW MOBILE DEVICE SCREEN ON MONITOR
To display the screen of a smartphone or tablet on a monitor, no special settings are required.
Just connect the port with a cable hdmi of the monitor with the door USB/C of the mobile device. This can be done with a special cable or with a cable hdmi to hdmi to which an adapter has been added USB/C to HDMI.
If audio is also playing on the device, the sound will be heard from the monitor speakers.
HOW TO CONFIGURE PC AND MONITOR AUDIO
When connecting a computer screen you can choose
what device to play audio from.
he goes up Settings -> System -> Audio -> Output
and then choose where to hear the sound from.
In fact, the options for the computer's speakers and those connected to the monitor will be shown.
USE MONITOR WITH OBS
We saw how with the free and open source program
Studio OBS
you can record the screen Computer. However, there is the difficulty that with only one monitor it is displayed
a matryoshka-style preview.
That is, you see the window of Studio OBS which registers. With another monitor available we can choose the option extend these screens and drag the windows we want to record onto the monitor.
Inside Sources is added screenshot but among the options you select to register it
Screen 2 leaving the interface
Studio OBS
inside Screen 1. In this way in
Screen 2 we could record the tutorial and give it Screen 1 Machete direction streaming from one source to another by previewing it.
