Connecting a phone to your TV isn't as simple as you might think. Whether you want to enjoy Netflix, share photos, or use it for home working, hooking up a cable between your phone and TV can be tricky.
For instance, if you plan to mirror your phone to a television for gaming, you'll want a USB connection rather than a wireless configuration. This vastly reduces lag. The same goes for watching movies on a TV over a USB cable from the phone.

Similarly, your connection method varies depending on your needs. Simply viewing photos on a compatible television requires your charging cable and mobile device. But for screen mirroring, you'll need a USB adapter.
Note that for USB connections between a phone and TV, the model of TV shouldn't matter, however. The steps below outlining how to connect your phone to a TV apply to Samsung, LG, and many other manufacturers. Better still, the same steps can be used to connect a phone to non-smart TV. (What is a dumb TV?)
MHL is one of the most common solutions for connecting a phone to a HDMI TV with a micro-USB cable. This technology allows MHL-compatible devices such as smartphones and tablets to connect to televisions and projectors.
Begin by plugging the SlimPort adapter into your phone. Then, attach the SlimPort adapter to your display using the proper cable. You should then be able to view your phone's screen on a TV. Like MHL, it's plug-and-play.
What if the TV you want to connect your phone to doesn't have HDMI? It is still possible to connect an Android phone to an old display, but you'll need dedicated adapters to switch formats and possibly chain them together.
Wondering how to connect an iPhone to your tv with USB? Sadly, this isn't possible. As iPhones and iPads don't have USB, you can't use this as a connection method. But you can connect iOS devices to a TV using a cable.
If you own an iPhone 5 or newer, it will have a Lightning connector. To connect your iPhone to a TV you'll need the Lightning digital AV adapter for HDMI outputs, or the Lightning to VGA adapter if you have an older VGA display. Buy the cable that fits your TV and phone. Older iOS devices with the old 30-pin port instead use the 30-pin VGA adapter.
You can connect an iPad to your TV through the same means. Again, you'll most likely need a Lightning cable for this. Only the iPad 3 and earlier use a 30-pin cable. All other iPads, including every iPad Mini and iPad Pro, use a Lightning cable.
Once you've plugged in your adapter, simply hook up the video output to your display. Then, your phone screen will mirror to the TV. Apple's official Lightning adapters contain an additional Lightning port for charging while viewing content on a second screen.
While the most common use case for connecting a phone to a TV using USB is for screen mirroring, there's another option. Instead of screen mirroring, you can connect it as a storage device for viewing pictures and videos on your TV.
Of the various USB to TV connection options, this is the easiest. Since it only requires a phone, USB cable, and TV with a USB input, it's simple to set up. Which specific cable you need depends on your phone.
On an iPhone or iPad, use a Lightning cable (or 30-pin for older devices). Alternately, Android users need a micro-USB or USB-C cable. The USB cable that came with your phone or tablet should work fine.
On Android, it's likely you'll need to change your USB settings to Transfer files or Transfer photos (PTP). To do this, drag down your notifications from the top of the screen when connected. In the menu, tap the USB is charging this device notification to change it.
Among the most popular Android devices available, you'll find Samsung flagship handsets. These feature connectivity with televisions and monitors. For pure screen mirroring, you'll need a USB-C to HDMI cable.
To connect a Samsung Galaxy S8/S8+/Note 8 and later (including the Samsung Galaxy S21 range) to your TV, merely hook up a USB-C to HDMI adapter. Plug the USB-C male into the USB-C charging port on your Samsung Galaxy device. Then run the HDMI cable into your TV.
However, Samsung Galaxy S8, S9, and Note 8/9 devices also include DeX. Bridging the gap between mobile and desktop, DeX offers a desktop experience run from your handset. You can run all the same Android apps, however, access your phone's gallery, and basically get everything on the big screen.
Since this is proprietary technology, the method for connecting a DeX-enabled Samsung phone to a TV differs from standard hook-ups. In some cases, you'll need a dock to use DeX. In others (such as the recent Galaxy Note phones) you can use a USB-C to HDMI cable, which is more useful than a dedicated dock.
Knowing how to connect a mobile to a TV via the USB cable is useful when there is no wireless connection available. While a USB to TV connection varies by device, connection type, and display inputs, it's thankfully simple to set up. However, don't forget that wireless casting is usually more convenient.

When setting up Harmony Smart Keyboard, Harmony App will guide you through testing basic AV control of each device. This will typically use IR commands, except for a few devices like Mac & Windows computers, PlayStation and Xbox game consoles and Roku.
When creating your Activities, you may have the option to associate text entry functionality to one of the devices within each Activity. This will usually require an additional pairing step where you tell Harmony Smart Keyboard how to send these extra commands to the chosen device.
Apple TV as well as some models of Mac or Windows computers and Smart TVs support text entry over Bluetooth. When you choose to connect Harmony Smart Keyboard to a device using Bluetooth, Harmony Hub will put itself into pairing mode. At this time, you must also enable pairing on the device you want to control. For most devices, Harmony App will provide specific instructions on how to enable Bluetooth pairing.
If your USB device is not being detected, plug in a USB mouse and see if the mouse laser light turns on, indicating that the USB port is supplying power to the device. If not there may be a problem with the port.
It has been coming "On Screen", that my "USB Port is not Supported", I don't know what it is ( well, I know the USB that you use to charge your phone, that's all) I had a USB Adapter plugged into my TV to use my "Strip Lights", but I have not had a USB plug in that I know of, I am not having any problems with my TV, just that message that comes on Screen, can you Help, please?
On some LG TVs the USB port is used solely as a service port to connect test equipment by service personnel and it is not used for anything else. Perhaps that may be one reason the message appears. Check the user manual for your model to see what it says about the USB port.
When i try to put in my usb (Sandisk) it started showing unable to support usb drive i tryed putting it it said the same thing so i put in my other usb which is not SanDisk and it worked immediately please i don't understand what the problem is can you help please
Either it doesn't like the SanDisk for some reason or maybe the SanDisk is a bigger capacity flashdrive or maybe it has been formatted differently to the one that works and what the TV supports e.g. NTFS or FAT-16 or FAT-32 or APFS or HFS+ or exFAT or even something else etc
I have an LG HDR 4K monitor connected to a Macbook Air laptop via USB Type-C, and a PC via HDMI. I also have a keyboard and speakers connected to the same monitor via USB. Since the monitor and the Macbook are connected via USB Type-C, the monitor and the Macbook make a "pair" meaning that the monitor charges the laptop, works as a second screen, and connects the keyboard and speakers to the laptop seamlessly. However, those speakers and the keyboard connected to the monitor are not visible to the PC since the monitor and the PC are connected via HDMI. My question is if there is a way to avoid unplugging the USB devices connected to the monitor and plug them into the PC every time I switch to it, i.e. work the same as it does with a Macbook?
Connecting two computers to one display, keyboard, and mouse is a relatively common thing to do and there's a wide variety of products for this purpose. The problem is that these KVM switches expect both computers to attach to the display with the same kind of interfaces. Getting a KVM switch that supports 4K HDMI, speakers, keyboard, and mouse is easy enough, but then you will need a dock for the laptop to split out the USB-C to HDMI, USB-A, and power passthrough for a USB-C power supply. The KVM switch could likely be had for about $150 and the dock for about $50.
I have seen displays with a built-in KVM switch so check the manual on if your display supports this before you go buy anything. The displays I've seen with a built-in KVM switch will have a USB-C port to connect one computer and USB-B to connect the other computer. As you discovered there must be a USB data path for the keyboard and mouse to work on both computers, and to get that means two USB ports, if you don't have two ports to connect two computers then there's no KVM switch in the display.
Although they've been around for a few years now, USB-C ports are finally becoming widely adopted on monitors. They're versatile, reversible, and can deliver power to charge up your mobile devices, like your laptop. Some monitors even have built-in USB hubs that allow you to connect USB-A devices to the monitor and control your laptop, leaving the limited ports on your laptop free for other things. Modern USB-C monitors have DisplayPort Alt Mode so you can display an image from a compatible device, but the power delivery differs between models. 2ff7e9595c
