How to Watch TV in Another Room Without Running Cables

Watching TV is the world's favorite pastime. Traditionally, televisions are the centerpiece of a living room. However, these days it's common for them to be in just about any room. This can be irritating since cable companies tend to only install a cable box near one TV unless customers pay for additional connections, and sometimes the room where you want to watch TV is across the house from where the cable/satellite wiring enters. Fortunately, there are ways to send a signal to another room without going to the trouble of running wires through your entire house.

Instructions

Connect Using a Wireless AV Transmitter and Receiver

Wireless transmitters use infrared (IR) signal to communicate between the receiver and the transmitter. Before getting started, make sure that the television that the cable box is currently installed on is connected to your Wi-Fi. Connect the hdmi av transmitter to the cable box using an HDMI cable and power it on(RCA av transmitter for signal source device with RCA/AV port). Make sure it's plugged in correctly and that the light is on.

Move to the room that contains the TV that you want to watch cable on. Plug the wireless receiver in near this TV using the additional HDMI cord. Power both the TV and the receiver on.

Navigate to your Input options on the TV and choose HDMI. The wireless receiver and transmitter may have multiple input options. If so, press the Input button on your wireless receiver and transmitter to select HDMI. You should now be able to watch cable on the second TV. You can use your cable TV remote control or universal remote to change the channels on the second TV.

Connect Using a Dongle

A dongle is a fairly new method of wireless connectivity that doesn't involve cable or even a second television. The dongle uses Wi-Fi connectivity instead of infrared to transmit streaming videos and TV from smart phones to televisions. If you have a smart TV, this is one way of watching TV without the use of a wired smart box or cable box.

You will need to have a video streaming app like Netflix, Hulu, YouTube or Amazon TV on your phone to use this method. Make sure that both the TV that you want to watch on and your smart phone are connected to your Wi-Fi. You can find the Wi-Fi connectivity option in your phone's Settings menu.

On your smart TV, navigate to the Google Play store, the Apple Store or its equivalent. Download the same video streaming app that your phone has. Log in to the app on your TV.

Open the same app on your phone. The app will display a small box-shaped icon in the top right corner. This is the dongle icon. When you touch the dongle, it should display all of the nearby smart devices that it can stream to. Select your smart TV from this list and wait for the connection to appear on your television. Once the connection is made, you can search for and play videos on your phone like normal and they will appear on your TV.

Connect Using a Channel App

Some channels such as HBO, TNT and CNN have apps that you can download to and watch on a smart TV even if that TV isn't hooked up with cable. First, sign up for an online account with your cable provider. Next, access the app store on your smart TV and download the apps for the channels you want. Log in using your cable account and begin watching TV.

Compare HDMI & DisplayPort

Author: pakite

Eight years ago, DisplayPort come out, someone said Displayport will replace HDMI in the future, but for now, Displayport didn't reach the their expectation, it looks like only a little chance to replace the HDMI. But it's why? Displayport has advantage for technological and better than other’s, including HDMI can not reach it’s technological.

DisplayPort technical standard:

DisplayPort has developed 1.4a, and this is based on VESA Displayport at Sept 2014, the new vision 1.4a has HBR3 transmission model, 8.1Gbps transmission band, also combined VESA DSC 1.1 display compression standard, The combination of this two can allow the embedded display panel to support the highest resolution of 8K. From this technical standard we can analyze a keyword "bandwidth". the transmission of high bandwidth content is advantage of the DisplayPort interface, DisplayPort interface is based on the fundamental.

Technical standard of HDMI interface:

HDMI Jack has developed 2.0 Vision, but the new jack still not commonly used. Now the popular HDMI 1.4 standard support 4K resolution output but only for 24fps and 30fps frame rate, HDMI 2.0 could capable of handling 18000 trillion bits / sec data, enough to make 12 color screen display with high frame rate 60fps per second .

Compare HDMI and DisplayPort:

From the development, we can found the DisplayPort interface is superior to the development of HDMI interface in technically area.  after all, DisplayPort interface can transmit 8K resolution content. While the HDMI 2.0 version only support 4K 60-frame content. There is no big difference in other technical between of them, both of of then can transmit audio and video at the same times, and there is no difference in the physical interface, The most important difference is still bandwidth.

But we know the current ultra-high resolution equipment is not commonly used, only a few of 4K resolution products in the market, as the display industry's top configuration, 8K content will began at 2018, besides,only a little of 4K resolution resolution for now. So the bandwidthadvantage of DisplayPort has not displayin currently. Moreover, after 2018, both have to be upgraded, the capacity of HDMI  should be improved to meet the needs of user.
