How Can I Hookup My Mobile Phones To My PC Monitor ?

[borobhaisab]

Hiya,

I program on PC laptop mostly throughout the year.
And in winter, program on my mobile phone. Nokia 2 (old timer).
I got now Samsungs which are better. So thinking of programming on them too, just for fun (so to speak).
I am curious to see my Samsungs Desktops on my PCs monitor.
Meaning, I want to hookup my Samsung Mobile Phones to my PC monitor so I do not have to use the mobile's little screens but use the PC monitor's big screen instead.
now, my mobiles use usb charger. That means, they only got usb ports.
So, which type of cable or connector I should buy to hookup the Samsung Phones to my PC monitor ?
I guess I will need some kind of adapter. So, which one ? Care to advise ? better, care to provide a link to any store selling those particular adapters ?

Oh, I forgot!
How can I connect my pc keyboard (Logitech) and mouse to my Samsung Galaxy A9 (Mobile Phone) ?

MOUSE: LOGITECH B-100
KEYBOARD: LOGITECH K120

I would NOT do this. The A9 wasn't on the list of phones according to Samsung that had this feature.

But hey, try https://www.ebay.com/itm/272284482999 and for the keyboard and mouse go get BLUETOOTH models.

I've seen folk do this and they feel upset it doesn't turn the phone into anything useful.

FOR MUCH LESS MONEY and effort you can find a Rasberry Pi for what I've read you want to do.

How on earth do you effectively program from your phone?!

[mschuller]

Use a modest size smart TV instead of a monitor. Cast your phone.

I programmed on my phone in winter 2019 & 2020. I had no choice as it was freezing to stay too long infront of my pc or laptop in my bedroom. And so, I used to sit near the cooker in the kitchen and program on my phone. I hated at first but if I wait for winter to finish before sitting on my computer then I will have to wait 3 months doing no programming. hence programmed on the phone. I got used to it. But ass soon as winter finished, went back to pc.
I tried again just a little in winter 2021 but then felt frustrated that time and did not bother programming atall and waited for winter to disappear. Waited till feb/march. Did plan on buying a tablet to replace the phone as I can program on the tablet from under the blanket on my bed.
But, this time 2022 winter was not that cold and so still sitting at my laptop in bedroom. Did not buy the tablet nor try programming on the phone.
Now come to think of it, I wonder how did I find patience to program on my Nokia 2 screen dec-mar 2019-2020 & dec-march 2020-2021. This time round does my head & eyes in. Maybe due to me starting to have eye problems now as I see blurry after becoming 43. Mid 40's now. Will be starting late 40's from next yr. Will need glasses to read small texts now. I hate wearing glasses.
Not gonna nosey about your actual age but I guess you are younger than me about 2-6yrs. But if you're older than me then let me know. Nice learning programming from a younger miss. ;)
Or maybe you're a generation younger. But if I remember correctly, you have been programming since late 90's and so I guess you must be in your early 40's.

@rproffitt

Thanks! But would this hookup to my pc monitor aswell ? Want to still make use of my monitor.

@mschuller

Sorry mate. English is my 2nd language.
What do you mean by "cast my phone" ? You mean "project" ?

[mschuller]

Regarding what do I mean by "Cast"- English is my 1st language and I wasn't sure which word to use. Project seems equivalent. Or Mirror or Display. Direct physical connection can also be done with a HDMI cable that has a USB end that matches your phone. https://www.samsung.com/ie/support/mobile-devices/how-can-i-view-my-samsung-smartphone-screen-on-my-tv/

[Mirhun]

I believe that there must be some ways. Some soft maybe? Who knows..

[Mirhun]

I still believe that it is possible

make sure your Samsung phone supports Samsung DeX. Most recent Galaxy S and Note series phones do.Then, get a USB-C to HDMI adapter. This adapter will let you connect your phone's USB-C port to an HDMI cable, which then connects to your monitor.To connect the adapter, plug the USB-C end into your phone, connect an HDMI cable to the HDMI port on the adapter, and plug the other end of the HDMI cable into your monitor. You can find these adapters on various online stores like Amazon, Best Buy, or directly from the manufacturer’s website. Once adaptor is connected, your phone should automatically detect the monitor, and you can use your phone inDeX mode.

If you want to connect your Samsung Galaxy A9 to your Dell E1916HV monitor, you'll need a USB-C to HDMI adapter (if your phone supports HDMI output). Since your phone has only USB ports, check if it supports Samsung DeX or screen mirroring via an MHL adapter. If your monitor only has VGA input, you might also need an HDMI to VGA converter.

Hiya,

If your Samsung phones have a USB-C port, the easiest way is to use a USB-C to HDMI adapter or cable. You would connect the USB-C side to your phone and the HDMI side to your monitor’s HDMI port. Your Dell monitor supports HDMI, so it should work fine.

Many Samsung phones also support Samsung DeX, which lets the phone display a desktop-style interface on a monitor when connected through a USB-C to HDMI adapter. ()

So generally you would need:
• USB-C → HDMI adapter (or USB-C → HDMI cable)
• HDMI cable to the monitor

Once connected, the phone can mirror the screen or start DeX mode on the monitor.

One important thing though: some older Samsung phones or budget models may not support video output, so it’s worth checking your exact phone model first.

Hope this helps!

To connect your Samsung phone to your DELL E1916HV monitor, you'll need a USB-C to HDMI adapter (if your phone supports USB-C) or an MHL adapter. These adapters allow you to mirror or extend your phone’s display to the monitor. You can find them easily on sites like Amazon or Best Buy. Make sure the adapter is compatible with your phone.

I use a $5 app I bought on the Microsoft Store. It is called Air Receiver (Softmedia). Running this on my laptop I can cast to it wirelessly from my Android phone as well as my Oculus Quest. The cast option on your phone may be in different places depending on your Android version. For mine, I go to settings and search for "cast". When you select cast it will say "not connected". If you run Air Receiver first then select "cast" you should see you computer in the list of possible targets.

you probably cannot connect your Samsung Galaxy A9 directly to that monitor with just a cable.

Here is why.

Your Samsung Galaxy A9 (2018) has a USB-C port mainly for charging and data, not for sending video to a monitor.
For a phone to send video through USB-C → HDMI, it must support DisplayPort Alt Mode / Samsung DeX, which is usually only available on Samsung Galaxy S / Note flagship models.

Because of this, a simple cable like USB-C → HDMI will most likely not work with your Galaxy A9.

What you can do instead

Option 1 – Wireless screen mirroring (easiest)
Use Smart View / Miracast.

You would need a small device such as:

Microsoft Wireless Display Adapter

Chromecast

Miracast HDMI dongle

Steps:

Plug the dongle into your monitor’s HDMI port

Connect the phone using Smart View / Screen Cast

Your phone screen appears on the monitor

Option 2 – DisplayLink adapter (wired but more complex)

You could try a USB OTG → DisplayLink USB-to-HDMI adapter and install the DisplayLink app. Some people use this workaround when phones don’t support native video output.

But this is slower and not always perfect.

About your monitor

Your Dell E1916HV 18.5" LED Monitor supports HDMI and VGA, so any HDMI mirroring device will work fine with it.

My recommendation

The simplest and cheapest solution is:

👉 Buy a Miracast / Chromecast HDMI dongle and mirror your phone wirelessly.

If you want, I can also show you the exact $10–$20 adapters that work best for this setup.

Your laptop is a portable device, so take it to the warmest room! You can also take along you monitor. The more screen space you have the easier things will be as you can have several things open at the same time, covering half or a third of the biggest screen, and two things open on the smallest screen, each about 80% of the screen width, overlapping and offset to make rapid switching easy.

For example when updating a website, I have the list of things to do open along with a view of the changes in the browser, while the editor is on the smaller screen, sometimes with two 80% wide views both on the laptop. That's what I have open just now, until I decided a look at my email in a separate browser tab was a good idea, and now this tab to write a reply. And my tablet ready to be switched on if neccessary.

Programming using a phone is just silly, for a start the keyboard is so small, as is the line width, even in landscape view. The only reason I'd look at the phone would be to check the work looked good on such a limited screen size.

PS I've been working this way for over 25 years now. (Not on the same thing of course ;) )
