I'm having trouble connecting my LG Smart TV to a windows 10 laptop. When I go to Settings>Bluetooth and other devices I can see the TV in question listed under other devices with a note underneath "not connected". When I go to settings>wifi direct
on the TV it doesn't see the laptop. Any suggestions?

Thanks. I contacted LG and was told Window 8.1 bug, which was corrected by an update. I'm looking for a link to that update. Connecting PC to LG tv via wifi. TV is smart tv with wifi, which I confirmed is working. Connection using Smartshare apt.

Audio Connections

If you are using VGA or DVI to connect your computer to a TV, you’ll have to find another way to get your audio going. You basically have two choices: you can use external speakers that you hook up to your computer (or use the speakers built into your laptop),
or you can use a separate audio cable to output the sound from your computer to the TV.

DVI to HDMI

You’ll probably never see a laptop or television with a DVI port on it. However, it’s pretty common to find them on desktop computers. DVI uses digital signals to send video output, so it can be easily adapted to HDMI while still maintaining great quality.
The biggest drawback to using DVI instead of HDMI is that it doesn’t carry audio.

Making Wireless Connections Between Computers and TVs

As an alternative to cables, you can also use any of several different methods to set up wireless connections between computers and TVs:

• Some so-called smart TVs support Wi-Fi.
• For the many televisions that do not support Wi-Fi, you can install a separate unit between the computer and TV. Wireless dongles (sometimes called "digital media receivers" or wireless PC-to-TV systems) like Google Chromecast plug into a TVs HDMI
  port and enable Wi-Fi.
• Older PCs could be installed with Windows Media Center Edition (MCE)
  that supports streaming to your television in addition to receiving television on the PC via
  TV tuner cards and shared across a home network via Media Center Extender product like the Linksys DMA2100.
