I have a vizio TV, and I can't see from my laptop. But I can see from my laptop in another vizio tv.

You must have a smart TV for this setup.

It's not the TV it's the computer go to settings and turn on the port

Have you checked these?
1. Input settings in the TV,
2. Cycle the laptop output (laptop screen, external screen, both)

When you connect the vizio try changing the resolution settings on your laptop to see if that makes a difference. Could be that your video card output is not really compatible with the higher requirements of the Vizio.

In your TV's menu there should be a wireless setup. You didn't supply the Model of the TV. Here's a manual for a Vizio: http://store.vizio.com/documents/downloads/hdtv/M3D650SV/1185QSG_M3D650SV_B.pdf

You need a standard VGA cable to go from the laptop to the TV. Keep in mind that the sound will still come from the laptop not the TV speakers. You can get a cable here if you need one.

Check the tuner i/o board connector there might be a loose connection from the soccket.

I/O board means input output board, this is where the antenna and audio video input are pack in.It is just inserted at the socket..check whethere the connectors are lock properly

If your laptop has a VGA port, your Vizio needs to have a VGA port too so you can use a standard VGA monitor cable.

If your laptop has a DVI port, you hook it up to the Vizio using a DVI-to-HDMI cable.

And if your laptop has an HDMI port, you hook it up using a standard HDMI cable.

Hope this helps.

I've been online looking for a solution to this problem and couldn't find a fix until today. I just got off of the phone with a Vizio Tech. He told me that some pc's have a way for the monitor to show the screen externally, and that there's usually a button, sort of like the input option on your TV but its an output button for a laptop in my case. It should look like a picture of a TV in and out of each other. Mine was located on the number four key. I had plugged in my wires and put the TV input on RGB. then on my laptop pressed the function key and number 4 key at the same time and what do you know, I had a picture on my screen. I almost gave up on my vizio but love it even more now. I hope this helps.
