Short version of this Fire TV Stick 4K Max review: it’s still the Fire stick to buy, and in late 2026 the reason is bigger than speed. Amazon’s newest sticks, including the 2026 Fire TV Stick 4K, now run Amazon’s own Vega OS, which can’t sideload apps and drops Dolby Vision on the new 4K. The 4K Max (2nd gen) stays on Android-based Fire OS, with Dolby Vision, HDR10+, Dolby Atmos, Wi-Fi 6E and 16 GB of storage. The trade-off is the home screen, which pushes Amazon content and ads hard.

Our verdict
Score: 8.0/10. Fast, fully featured, and now the only current Fire stick with Dolby Vision and sideloading. Knock it down if home-screen ads bother you; a Roku is cleaner.

What the reviews don’t tell you
Which Fire sticks still run Fire OS
Most 4K Max reviews were written before Amazon’s switch. In October 2025 Amazon said all future Fire TV Sticks, starting with the 4K Select, would run Vega OS, and AFTVnews reports Vega only installs apps from Amazon’s Appstore, with no sideloading. Here’s where the lineup stands, per AFTVnews’ list updated in October 2026:
| Device | Operating system | Sideloading |
|---|---|---|
| Fire TV Stick 4K Max (2nd gen) | Fire OS | Yes |
| Fire TV Stick 4K Plus | Fire OS | Yes |
| Fire TV Cube | Fire OS | Yes |
| Fire TV Stick 4K (3rd gen, 2026) | Vega OS | No |
| Fire TV Stick 4K Select | Vega OS | No |
| Fire TV Stick HD (2nd gen) | Vega OS | No |
If you rely on a niche app, a media-server client or anything outside Amazon’s Appstore, check that the box says 4K Max. The newer sticks look almost identical.
4K Max vs the new 2026 Fire TV Stick 4K
| Feature | 4K Max (2nd gen) | Fire TV Stick 4K (2026) |
|---|---|---|
| Operating system | Fire OS | Vega OS |
| Dolby Vision | Yes | No |
| HDR10+, HDR10, HLG | Yes | Yes |
| Wi-Fi | Wi-Fi 6E | Wi-Fi 6 |
| Storage | 16 GB | 8 GB |
| Processor | 2.0 GHz quad-core | 1.7 GHz quad-core |
The missing Dolby Vision matters most if you own an LG or TCL TV, which use it; Samsung TVs use HDR10+ instead, so either stick shows the best HDR there. The new 4K is cheaper and faster than older non-Max sticks, but for app freedom and Dolby Vision the Max is the safer pick. Compare platforms in Fire TV Stick vs Roku.
Wi-Fi 6E only helps with a 6E router
Wi-Fi 6E adds the less crowded 6 GHz band, but only if your router has it too. With an older router it runs fine on 5 GHz. If 4K buffers because the router is far away, Amazon’s Ethernet adapter is the more reliable fix.
Speed
In Tom’s Guide’s tests the 4K Max opened Netflix in 14 seconds versus 17 on a Roku stick, YouTube in 9 versus 13 and Disney+ in 7 versus 13, though Sling was slower. The Apple TV 4K was faster still. Tom’s Guide called the gains not very significant day to day, and TechRadar describes it as very speedy.
Picture, sound and Alexa
What Hi-Fi scored the picture 5 out of 5, praised its sharp detail and clean film grain, and made it a 2026 Awards winner. It supports every major HDR format and sends the best one your TV can show. Dolby Atmos passes through to a soundbar like the Sonos Beam. Output tops out at 4K 60, which is all streaming services need. When idle, Ambient Experience can show art, photos and widgets, and Alexa handles search, playback and doorbell cameras. If your home already runs on Alexa, that’s the strongest reason to pick Fire TV over Roku.
Setup and best settings
- Plug the stick into an HDMI port, using the included extender if it blocks the next port.
- Power it from the included adapter, not the TV’s USB port.
- Join Wi-Fi, sign in and let the remote set up TV power and volume.
- Turn on HDMI CEC Device Control under Settings > Display & Sounds.
| Where | Change | Why |
|---|---|---|
| Preferences > Featured Content | Video and audio autoplay off | Fewer distracting previews and less lag |
| Display & Sounds > Display | Frame Rate Matching on | Less judder on films |
| Display | Dynamic Range: Adaptive | HDR only for HDR content |
| If menus lag | Hold Select + Play/Pause | Quick restart |
To see fewer ads, turn off autoplay, double-tap Home to skip the full-screen ad on wake, and use the remote’s app buttons to jump straight into apps. You can’t remove the ads completely.
What we liked
- Dolby Vision, HDR10+, HDR10 and HLG plus Dolby Atmos

What we didn’t like

- Skip it for the simplest, least ad-heavy menu, or if your TV’s built-in platform already works well. For an old TV see streaming devices for old TVs.
