Expert Answer

You can buy a receiver that plugs into your TV's HDMI port, like Chromecast or Apple Airplay. Once you have that, you can (if you need to) download the correct software onto your TV and then connect the receiver to you home's WiFi network. Once you've done that, you just have to pair your devices and then you can use your TV through your PC.

Question

How should we connect a computer to an LED TV?

Community Answer

HDMI is the best option. However, some computers are not equipped with an HDMI output, in which case you'd use a VGA cable.

Question

How do I make the cursor work when connecting my PC to my TV?

Community Answer

Using your keyboard and mouse, the TV simply becomes the computer's monitor. You can purchase wireless keyboards and mice to hook to the computer to facilitate remote use.

What are the advantages of connecting my TV to my PC?

Question

My PC is connected to the TV through an HDMI cable. When I turn on the PC, the start up HP sign comes on the screen, but then the TV screen displays "no signal." What could be wrong?

Community Answer

On your TV, select where the input is coming from. If your TV has more than one HDMI port, make sure you select the correct port, ie: HDMI1, HDMI2, etc.

Question

I have the laptop connected to the TV with an HDMI cable and no picture from my laptop to TV, what could be wrong?

Community Answer

Make sure that you have the correct HDMI input selected on your television. You may also have to manually redirect video output to the TV by pressing the correct display option on your notebook; usually this is a combination such as holding the Function key and pressing F5 or similar (consult your laptop's manual for which function key is for display).

Question

How do I find the HDMI port on my PC?

Community Answer

It should be near where you plug in your computer monitor. It's entirely possible you don't have an HDMI output port on your computer, in which case you can either get an adapter or use one of the other methods.

Question

Can a WiFi connection support 1080p gaming or streaming without stuttering?

Community Answer

It depends what kind of internet connection you have, how powerful your PC and video card are, how many devices are connected to the network, the strength of your WiFi signal, and a number of other factors. If you reduce signal interference and optimize your connection and PC speed, then it's feasible.

On your PC, go to Settings, and Type Devices. This method will only work for users that have a Smart TV. Press 'Add Device', then press Wireless Display. Make sure your TV is connected to the internet. An icon showing the name of your TV will pop up. Click on it. You should be connected.

Question

I am watching a show and then I lose the signal and I get a message that my HDMI is weak or no signal. I changed the cable but no change. Is it my PC?

Broken Knight

Community Answer

It could be that the port on either your TV or PC is damaged. Or, it could also be a damage to the components related to HDMI on your motherboard. Try using a different PC and TV so you might be able to troubleshoot/figure it our what's causing the error.

Question

I have connected my PC from one end of the house to my smart TV at the other end of the house. I never found a way to control the PC from my TV room. Is there a way?

Ciprian

Community Answer

If we exclude streaming or other options over the Internet/LAN that may have latency penalties then consider a long HDMI cable for the image and sound (there are alternatives for very long distances to avoid quality degradation, like HDMI optical cables or HDMI with Ethernet conversion along the way etc.) and separate usb cables for mouse and keyboard. Alternatively there is the new Thunderbolt over Optical cable that can go from your PC (if supported) into a dock that sits next to your TV and has multiple ports like HDMI and USBs. (Both options have nontrivial costs and require further analysis of your context/devices.)
