The 4-Series models come in 43, 50 and 55in and are cheaper than the equivalent sizes in the Omni Series, which additionally includes 65- and 75in options (these are the only two which support Dolby Vision).

The 4-Series are more affordable because they don’t have the mics, so you do need the remote to use Alexa.

What features do the Fire TV Omni and 4-Series have?

Omni Series:

The 43, 50 and 55in models have a 4K resolution and support HDR10, HLG, and Dolby Digital Plus.

If you buy the 65- or 75in model, these additionally support Dolby Vision and have a metallic silver finish instead of black.

All five models have a 60Hz refresh rate and built-in far-field microphones for hands-free Alexa, and this works regardless of whether the TV is on or off, or whether the TV is set to use an HDMI input (for a games console, for example).

Like the new Fire TV Stick 4K Max, the Omni Series supports the new Live Picture-in-Picture feature that allows you to see the feed from compatible security cameras overlaid on whatever you’re watching. If you have a Ring doorbell, the video will appear automatically when someone is at the door.

They also support two-way video calling via Alexa Communications, but you’ll need a compatible webcam to plug into the TV’s USB port.

A Fire TV Alexa Voice Remote is included: it’s much like the remote you get with a Fire TV Stick, but with some extra buttons to change the channel and other TV-specific functions.

Of course, you can ask Alexa to do a lot of things, including switching to a certain channel (you don’t need to know the number, just the name), switch to an HDMI input, play specific shows and episodes on Prime Video and Netflix, open apps and games, give you a weather forecast and everything else she can do on a Fire TV Stick and Echo.

Inputs/outputs across all models comprise:

Ethernet3x HDMI 2. 01x HDMI 2. 1 eARC / ARCCable/AntUSBIR EmitterHeadphoneOptical

4-Series:

The 4-Series is essentially identical to the Omni Series models of the same size. This means all three models have a 60Hz refresh rate and support HDR10 and HLG HDR formats.

Similarly, they also have the same 8W+8W speakers and the same range of inputs and outputs.

Their design is the same as well, with a black plastic finish and the same remote control.

To recap, the main difference is the lack of far-field microphones, which means no hands-free Alexa. Instead you have to press the Alexa button on the remote, then speak.

New smart home dashboard

Later this year, an ‘all-new smart home dashboard’ will allow you to view and control connected devices in your home.

You’ll be able to check if a device is on or off, control the device and its smart home group by voice, and view a new row on Fire TV that is specifically dedicated to smart cameras.

If you are using the Fire TV Alexa Voice Remote, pressing the Alexa button will slide out a shortcut panel at the bottom of the screen, where you can access smart home controls, communications, weather, news, and more.
