Roku Error Code 020 — What It Means & How to Fix It

What Does This Error Mean?

Roku error 020 means there is a problem with the HDMI connection between your Roku device and your TV. The Roku cannot communicate properly with the TV over the HDMI cable. This is often caused by a loose cable, a bad HDMI port, or an HDCP compatibility issue. Most cases are fixed by unplugging and replugging the HDMI cable or switching to a different HDMI port on your TV.

Affected Models

Roku Express
Roku Express 4K
Roku Streaming Stick 4K
Roku Ultra
Roku TV

Common Causes

The HDMI cable is loose at either the TV end or the Roku end of the connection
The HDMI port on the TV or the Roku is dirty, bent, or damaged
An HDCP (content protection) handshake between the Roku and TV is failing
The HDMI cable is too old, low-quality, or damaged to carry the signal reliably
The TV's HDMI port needs to be reset after a power interruption or firmware update

How to Fix It

Unplug the HDMI cable from both the Roku and the TV. Wait 10 seconds, then firmly plug it back in at both ends. Make sure it clicks or sits snugly.

A slightly loose HDMI connection is the most common cause of this error. The cable should feel secure and not wiggle when plugged in.
Try a different HDMI port on your TV. Most TVs have two or three HDMI ports. If one port has an issue, another may work fine.

Remember to switch the input source on your TV to match the new HDMI port number using your TV remote.
Try a different HDMI cable if you have one available. Older or low-quality cables can develop faults over time, especially if they have been bent sharply.

For 4K Roku devices, make sure the replacement cable is rated for HDMI 2.0 or higher to support the resolution.
Power cycle both the TV and the Roku. Unplug the TV from the wall completely, then unplug the Roku. Wait 30 seconds, plug the TV back in, then plug in the Roku.

A full power cycle resets the HDCP handshake between the devices, which fixes many HDMI communication errors.
Check your TV's HDMI settings. Some TVs have an HDMI format or HDMI mode setting that needs to match the Roku's output. Look in your TV's picture or input settings for options like 'HDMI Mode,' 'HDMI Format,' or 'Enhanced Mode.'

For Roku 4K devices on OLED or QLED TVs, the HDMI port often needs to be set to 'Enhanced' or 'UHD Deep Color' to work correctly.

When to Call a Professional

Error 020 rarely requires a technician. However, if you test with a new HDMI cable and multiple HDMI ports and the error persists, the HDMI port on your TV may be damaged. TV HDMI port repair is a specialized job — a TV repair technician can diagnose and replace the port. For older TVs, buying a new budget TV may be more cost-effective than a repair.

Frequently Asked Questions

What is HDCP and why does it cause connection errors?

HDCP stands for High-bandwidth Digital Content Protection. It is a system that streaming devices and TVs use to verify they are authorized to display protected content. Every time a Roku connects to a TV, they perform an HDCP handshake to confirm both devices are authorized. If this handshake fails — due to a bad cable, dirty port, or incompatible equipment — you get an HDMI error like 020.

My Roku stick is plugged directly into the TV's HDMI port. How do I check the connection?

For HDMI sticks that plug directly into the TV, the connection itself is the stick in the port. Make sure the stick is pushed fully into the port. If the TV's HDMI port is on the side and the stick is heavy, its weight might cause a slightly loose fit. In that case, use the HDMI extender cable that comes in the Roku box to take the weight off the port.

Does error 020 mean my Roku or my TV is broken?

Not necessarily. In most cases it is just a loose cable or a setting mismatch. Try all the steps above before assuming something is broken. If you can test the Roku on a different TV and it works fine, the problem is with your TV's HDMI port or settings. If it fails on every TV, the Roku's HDMI output may have a hardware issue.
