LG TV Wifi, connect to laptop to surf internet?

by 9bill6 / September 28, 2014 9:25 AM PDT

My 50" tv says it has wifi. Does this mean the tv screen can act as the monitor when I use my wireless laptop to surf the internet, etc.? The user guide shows picture of two wireless connections. One shows an LG Wireless Dongle (what's a dongle?) plugged into tv. Other pic shows just the tv and a wireless router, with each one showing the "signal" bouncing off it.

I have Comcast, and they gave me a combo router/modem. Said I don't need a separate wireless router to use the wireless laptop, and I do use the laptop fine.

So, is the tv already set up to be used with the laptop because I already have the router?

There are some sets that you can cast your screen but I can't find which LG it is.

Be aware LG never answered about their privacy issues at

In closing, if you have a WiFi router you should be able to use that with multiple devices as long as they are in range. TV's tend to have less range than a laptop. Figure 20 feet for the worst ones.

LG TV Model #
by 9bill6 / September 28, 2014 11:33 PM PDT

Model # is 50LA6205...however, just recently have been told by LG it is a Canadian model I was sold. LG chat session said they can tell me nothing about it because of that, and the warranty is no good in USA. If I needed warranty work, they said I'll have to ship it to Canada. Nice, huh? Bought it online from Tiger Direct. Contacted them....they said LG is wrong, go back and tell them. Contact LG again, they say Tiger Direct is wrong. Went back to tiger Direct. So now T-D tech said he will "escalate" this odd problem to his supervisor and someone will get back to me. Bet no one has ever heard of a nutty problem like this before.

Why not give it a shot.
by Oldartq / September 28, 2014 1:17 PM PDT

Not with the laptop but as though the tv is another laptop. Sounds like your router has an access point and if the tv is close enough to the router then you might be all set. Good luck.

don't get it...?
by 9bill6 / September 28, 2014 11:46 PM PDT

don't understand what you mean by..."not with the laptop"....Maybe I'm not clear...I thought there was a way to use the keyboard on my laptop but the tv screen would look like the monitor on my laptop. (?)
not easy for me to check things.....they talk about a "User Guide", a "User Manual", an "On Screen Manual", and an "Online Manual". They should make things simpler/easier.

It cuts both ways Wink We also need your laptop info to determine if it will be compatible with your HDTV.

What I recommend
by Pepe7 / September 29, 2014 12:21 PM PDT
In reply to: laptop info

Skip the Miracast, since it generally is a pain and unreliable. If you want to give it try, Bob posted a decent enough tutorial.

If I had a laptop that Lacks Widi chipset built-in (much more reliable than miracast), my choice would be a simple HDMI cable if possible. Works nearly 100% of the time, with no collateral issues to deal with like you do w/ wifi and/or Miracast. Any HDMI cable you had laying around would allow you to test out the performance of a wired connection. Either Amazon or could supply a decent quality 15-20' HDMI cable for a song.

If the HDTV's mounted in a high spot where the extra HDMI cable connection hanging off might be an issue, you could add a wireless bridge or wireless HDMI transmitting device. YMMV. Both I am still not satisfied with vs a straight wired connection.

Always visit the LG support site for that

That way you know what precisely the HDTV is capable of.

You look through this?

In reply to: don't get it...?

This may give you a little more understanding.

If you just want to use the tv as a monitor for your laptop, here is what's necessary. If your laptop don't have "widi", then a dongle is needed for the laptop to communicated with the tv to make this work.

In reply to: You look through this?

getting more mixed up the more I read. Is the "miracast" gadget only needed for 'streaming'? (does that mean movies?)

you are correct when you say if I just want to use the tv as a monitor for my laptop. That's it. TV owners manual says TV has wifi and widi. But I've never seen anything called widi having to do with my wireless laptop.

So do I need a dongle for both the tv and the laptop?

Look up.

It appears you have all the hardware you need. Frankly it's techy to setup but I supplied the usual tutorials. If it doesn't work, you should make some warranty claims.

Ijust don't get it
by 9bill6 / September 30, 2014 4:14 AM PDT

everything I have read sounds different to me.

Bottom line:
I have TV with both Wifi and Widi
I have a wireless laptop that does Not have Widi
I have Comcast combo router//modem on a shelf a foot below the TV
Laptop is 12 feet away

I just want to use the TV screen as a monitor for the laptop.
Walk areas, etc., means no wires can be between laptop and TV
But a wire can be between router/modem and TV
What is needed....a dongle for both TV and laptop?
How do I set this up? How do I turn it "on/off" to go back and forth between using TV as monitor while using laptop, and then just using laptop by itself and a "regular" TV?

Thanks so much, I'm sorry I am having such a hard time with this.

The missing WiDi in the laptop.
by R. Proffitt Forum moderator / September 30, 2014 5:34 AM PDT

That means you should try MiraCast. If you want to add WiDi I suggest you don't because it's not that cheap.

I have W8, not 8.1
by 9bill6 / September 30, 2014 12:26 PM PDT

My laptop came with W8. Tutorial says it has to have came with 8.1. Says if laptop was/gets uprgraded to 8.1 from an older version of W, then the laptop has to support Miracast (which mine does not)
Does this bring everything to a far as trying Miracast goes?

Collapse -
Yes. 8.1 will provide support for Miracast
by Pepe7 / September 30, 2014 2:19 PM PDT
In reply to: I have W8, not 8.1

You *will* have to update from 8 to 8.1 in order to get started with Miracast. I believe your laptop should be perfectly capable once you update. Double check using the method listed here though after upgrading to 8.1,news-18335.html
Pay special attention to the section that refers to 'Add a Wireless Device' under Devices > Project

Grab a wireless dongle to act as the miracast receiver on the back of the LG HDTV. The dongle plugs into a free HDMI port. I have absolutely zero experience getting one of these to work personally, but it's on my bucket list. Here's a Belkin from Amazon as one example which is reported to work successfully with 8.1.

upgrade to 8.1 wont work with miracast
by 9bill6 / September 30, 2014 3:19 PM PDT

You missed my second sentence.....the tutorial says, as I stated, if you do upgrade to 8.1, the laptop Im using already has to support Miracast, which it does not.
Also, when I click "Devices", the is no "Project" to click on

The upgrade part 2.
by R. Proffitt Forum moderator / October 1, 2014 12:29 AM PDT

After the OS is upgraded, you have to find the video drivers that add the MiraCast support. Annoying to say the least. At least that's cheaper than buying hardware.

Since it's Intel HD 4000 under the hood....

Let's be honest about this.

Microsoft and the industry is a mess. This issue had many opportunities since about 1995 to escape driver hell and didn't. Reading finds a few ideas about the HD 4000 driver for Windows 8.1.

Pull up a chair and stay awhile Happy

Here are your steps. Follow them religiously. Ignore the tutorial for now. More often than not, Microsoft has hidden features which become unlocked when you update the OS. I see your rig has the Intel HD 4000 graphics built in. That means it will likely also support miracast because the chipset is supposed to be compatible. YMMV. See here:

1) Backup the data on your laptop before upgrading the OS

2) Update the operating system to Windows 8.1

**The reason there is no 'Project' to click on is because you have not updated to 8.1 yet. 8.1 adds this functionality.

3) Buy the required dongle or miracast receiver (see my post above)

4) Configure laptop by adding the wireless device per above

The TV noted above may have MiraCast.

But to muddy the waters, the maker wrote this:
"WiFi certified Miracast™ allows you to mirror files from your Smartphone, tablet and other devices with Miracast™ without wires through Wi-Fi Direct®. It's a great way to mirror media you have created, so things like your vacation photos and recital videos can easily be viewed on the big screen.

If LG wrote it,....
by Pepe7 / October 1, 2014 1:50 AM PDT may be erroneous. It's a feature and not a service from what I saw at a few demos last year of some larger LG panels. We ended up with a 90" Sharp instead, so I gave up reading the misleading nonsense @ the LG "support" site at that point Wink

I will take another peek. There may however be an app that LG implements among their stable of 'smart' <ahem> features to achieve some of these results of straight forward (mira)casting though.

Hypothetically, once you have a separate receiver that can 'talk' to the HDTV via the HDMI port, it should be really simple given the laptop has been upgraded.

by 9bill6 / October 1, 2014 5:10 AM PDT

I think this has now gone way over my head to do all this stuff. More and more involved. Looks like I'll have to forget about it. I thought it would be such a simple thing when I bought the TV making sure it said "Wifi". Figured I could just plug something in and turn it on and I'm set. Maybe I could do about half the stuff you guys are now talking about, but....backing up and updating....configuring dongles....bunch of stuff I've never done, just barely recall having even heard the terms before.

Thank you very much for all the time and effort in trying to help, but I just don't think I can do it. So, looks like I'll be staying with a 15" monitor instead of a 50" monitor. Worried I'll make a mess out of things and end up with laptop all fouled up.

Help, my PC with Windows 10 won't shut down properly

Since upgrading to Windows 10 my computer won't shut down properly. I use the menu button shutdown and the screen goes blank, but the system does not fully shut down. The only way to get it to shut down is to hold the physical power button down till it shuts down. Any suggestions?
