If you have an older, lower resolution TV, and you’re thinking about buying a Firestick device, you’re probably wondering whether or not it will even work.
Does Firestick work on any TV?
No, Firestick does not work on any TV – it must have an HDMI port! If you have an older, lower resolution TV, your Firestick should automatically down-convert to the best available resolution. On rare occasion, some old, 720p TVs cause an “invalid format” error and cannot be used with Firestick.
The good news is that most TVs on the market today have at least one HDMI port, so you’re most likely fine there.
Minimum requirements for Firestick
In order to get your Firestick working, there are a few basic requirements that must be met.
- As just mentioned, your TV must have an HDMI port.
- You also need a wireless internet connection that you can connect your Firestick to.
- This just means you need WiFi. A common misconception is that your TV needs to be a smart TV in order to work. That’s not true. In fact Firestick is what actually makes non-smart TVs, smart.
- If you do have a smart TV, Firestick will still work.
- Finally, you’ll need an Amazon account to register your device.
- You don’t need to be an Amazon Prime member.
- And if you bought your Firestick off Amazon, your device will come automatically registered!
If you have all of these basic requirements met, then most likely your Firestick will work no problem!
But, there are always a few exceptions…
Lower resolution TVs
TV resolutions today are crazy good. There are affordable 2K and 4K (Ultra HD) options everywhere!
But it wasn’t all that long ago that “High Definition” (720p) was all the rage. Launched in 2001, HD was the ultimate buzz word. If your TV didn’t have it, you were missing out.
Today, the story is quite different. It’s rare to find a TV that’s 720p anymore. But of course, they do still exist.
Firestick devices came out in 2014, nearly 13 years after the introduction of 720p. By then TVs had already moved on to 1080p resolution and beyond.
So it’s no wonder that Firestick devices occasionaly run into compatibility issues when being used with older 720p TVs.
I’m not saying that if you have an 720p TV, your Firestick won’t work. There is a high probability that you won’t run into any problems at all.
Firestick devices should automatically adjust and down-convert to the best available resolution that your TV has to offer.
But sometimes that doesn’t happen if the device’s resolution setting isn’t set to Auto.
Manually change Firestick resolution settings
If your Firestick device is giving you trouble on your older TV and the format isn’t quite right or something is just off, I recommend you try the following.
If you hold BACK and REVERSE and RIGHT and SELECT simultaneously on your Firestick remote for 10 seconds, the TV will begin to cycle through various resolution settings.
(For the final version of Fire OS 5, the button combination to bring up resolution cycling has been changed to holding REVERSE and UP for 10 seconds.)
It will stop at each setting for 10 seconds and cycle to the next option if you do not press SELECT.
Pressing SELECT will save the current display setting. This can be useful if somehow your TV is set to a resolution that your TV doesn’t support.
If you attempt this and after 10 seconds nothing happens, just wait a bit. It likely worked and is actively cycling through settings. Once it finds one that works your TV should light up.
See if that does the trick. Occasionally this won’t work or you’ll see an “invalid format” error appear.
If that’s the case, definitely try the work around that I describe next.
Use a newer TV to lock Firestick resolution settings in place
It is possible that your Firestick device settings were previously hard set to a TV resolution that your current TV doesn’t support.
And if you’re unable to force the device to cycle through available resolution settings using the step above, then you should do the following.
Disconnect your Firestick device from the TV you’re having trouble with and connect it to a newer TV. Now you should be able to set your Firestick resolution settings to 720p (or whatever resolution your TV has).
To set the resolution press and hold the HOME button on your remote, then select SETTINGS > DISPLAY AND SOUND > DISPLAY > VIDEO RESOLUTION.
Then select the correct video resolution that will work for the old TV you wan’t to use the Firestick with.
Now disconnect the Firestick from the newer TV and reconnect it to the older TV. It should work now!
The problem is that if you only have the one older TV, the stick won’t even show up and so you can’t get to the menu to change resolution.
So there is a workaround, but it’s a pain and won’t work for everyone
A word on VGA connectors
Don’t try using an HDMI > VGA connector – you will most likely have cropping issues at 720p invalid format as the resolution is incompatible.
Simple as that.
I’ve read enough complaints from folks who didn’t have an HDMI port on their TV and tried and failed to use a VGA connector as a work around.
I’d just avoid this altogether and get a TV that actually has an HDMI port or just don’t use Firestick.
Will a 4K Firestick work on a non-4K TV?
Yes, a 4K Firestick will work on a non-4K TVs just fine. And similarly, you don’t need a 4K Firestick for your 4K TV either. In both cases you just won’t get 4K resolution but your Firestick device should work no problem.
Honestly though, if you don’t have a 4K TV, I wouldn’t buy the more expensive 4K Firestick. You’re paying for the higher-resolution option that you can’t even use.
As long as your TV has an HDMI port and you have an available WiFi network, you should be able to use your Firestick device on your TV without any problems.
That said, some older 720p TVs can run into resolution compatibility issues. While your Firestick should automatically down-convert to the best available resolution, that doesn’t always happen.
Luckily there are a few work arounds you can try.
One is to use the remote to force your Firestick to automatically cycle through the available resolutions. The other is to use a newer TV to hard set the resolution settings before reconnecting it to your older TV.
I don’t recommend trying a HDMI > VGA converter if your TV doesn’t have an HDMI port. I just have not heard a lot of success stories and you’re likely to have formatting challenges.
On rare occasion, some old, 720p TVs cause an “invalid format” error that simply cannot be overcome and likely cannot be used with your Firestick.
