Am i able to use a Roku express with the Vizio 1080p?

The Vizio VO230E does not have network capabilities built in. The TV has built around 2009 before many TVs included either wired or wireless networking. The manual has the specifications on page 61; the manual is available here: http://cdn.vizio.com/manuals/kb/legacy/vo320emanual.pdf .

To get a wireless connection, you need to connect some sort of streaming device with wireless networking to the TV. This can be a computer, a ChromeCast and your phone or tablet, a Roku device or another streaming box. Plug the HDMI cable (or device plug) or the device into one of the two HDMI ports on the TV. Connect the device to a power source, if one is needed. (For devices that use a USB power connection, do not connect the USB power cord to the service port of the TV. Connect it to a charger.)

Since your choice of devices range in price from the ~$15 Roku Express to several hundred dollars for computers, depending on the specifications, you will need to decide which features/platforms you want.

I hope this helps.

What's the Difference Between the Roku Express and Roku Streaming Stick?

well no, you need to use another source on the second tv for Netflix to come in. I have the Vizio smart tv with Netflix built in and I use the Roku box on my 2nd tv.

Roku 2XD does not have an ethernet port so you have to improve your Wifi capability. Using a Wifi booster will help but not reliably connected always.

If what I am thinking is correct and you're referring to the link code of your Roku, make sure that your Roku is still connected to the Internet and get a new code.

This error normally means that the Roku can't get past your router's security or it is connected to a Guest network. Make sure that you're not connecting the Roku to a Guest network.

On your computer's internet browser, access www.roku.com/link and enter the code. Once entered, it will then ask you to create a Roku account.

You really don't think you set the TV for this, if the TV supports 1080p and the device was 1080 capabilities then the TV will recognize this. If you using a cable box make sure your using the HDMI port on the cable box. I have seen in the past cable companies just using the component ports.
