How to Enable 4K on Your Vizio TV

Vizio makes a wide range of 4K UHD (ultra-high-definition) TVs, all of which have native 4K image quality and HDR support. HDR stands for “high dynamic range,” which is a feature that gives a picture more contrast. So, the colours on the Vizio TV screen look more like they really are. In this article How to Enable 4K on Your Vizio TV.

If you need to turn on 4K on your Vizio TV, you’re probably using a computer, gaming console, or other external device that doesn’t show up in 4K on your TV. When using game consoles, Blu-Ray players, Roku, a Fire TV Stick, and other devices, you need to turn on HDR through the TV’s settings or the right Vizio Smartcast App.

What is 4K?

A 4K display has at least 8 million pixels that can be used. The standard size for this resolution on TVs is 3,840 by 2,160. The resolution of digital cinema 4K, which is used in 4K movie theatres, is 4,096 by 2,160. No matter how you look at it, it has four times as many pixels as a 1080p screen and over 23 times the resolution of a standard definition TV.

Because of this, it’s clear that 4K is much sharper than 1080p. A 4K TV of the same size can fit four pixels where a 1080p TV can only fit one. That’s a big improvement in clarity, assuming you can watch native 4K content in that resolution.

What is HDR?

High Dynamic Range is what “HDR” stands for. The word comes from photography, and it means a way to make the difference between the brightest whites and the darkest blacks in a picture stand out more. The idea is that a picture will look more like real life if it has a wider range of tones, or “dynamic range.” HDR for TVs is pretty much the same thing.

Watch the sky. Even if the clouds are white (or grey, if you’re in the UK), there should be layers. You should be able to see different shades of light around the clouds. Now look at the TV screen to see clouds. In comparison, they often look flat, with crushed bright colours and layers that are almost impossible to tell apart. This is true for more than one reason.

How to Turn on 4K HDR via the Smartcast App

  1. Download and launch the Smartcast app on your iOS or Android device.
  2. Tap on “Settings” in the app.
  3. Select “Inputs” and choose “HDMI Color Downsampling“.
  4. Enable HDR on the HDMI port you’ve connected your device to.

Enable 4K HDR through Vizio TV Settings

  1. Turn on your Vizio 4K TV.
  2. Navigate to “Input Settings“.
  3. Select the correct HDMI port.
  4. Enable the “Color Full UHD” option.

FAQs

How do I make my TV support 4K?

Right now, you’ll commonly find HDMI 1.4, 2.0, and 2.1 ports on your TV. To pass 4K content, the port, cable, and source need to be compliant with a protocol called HDCP 2.2. If your TV won’t display 4K content, it’s possible you’re plugging into an incompatible port.

Why is my TV not showing 4K?

Make sure your HDMI cable is plugged into the correct port on your TV. Some TVs support their full set of 4K features only on certain ports. Refer to your TV manual or try the different ports on your TV. Check your TV’s settings menu.

Do 4K TVs automatically show in 4K?

If 4K content is available and your internet bandwidth can handle the data load the applications will generally automatically stream the video in 4K. The resolution may automatically drop and buffer if your internet connection becomes congested.
