In 2025, smart TVs have advanced beyond simple content streaming; instead, they now serve as central hubs for connected smart homes. Among the leading contenders, the Fire TV Omni QLED vs Samsung QN90C comparison stands out for Alexa-focused buyers.
On one hand, the Amazon Fire TV Omni QLED delivers premium 4K visuals with built-in Alexa voice control. On the other hand, the Samsung QN90C Neo QLED offers brilliant picture quality alongside powerful smart features.
Therefore, this guide will compare their features, voice assistant performance, and smart home integrations to help you decide which TV suits Alexa users best.
Fire TV Omni QLED vs Samsung QN90C – Voice Assistant Experience
When comparing the Fire TV Omni QLED vs Samsung QN90C, the difference in Alexa performance becomes immediately clear.
Fire TV Omni QLED – offers native Alexa support with hands-free commands. For example, say “Alexa, open Netflix” or “Alexa, turn off the lights” without needing a remote. Furthermore, Alexa is fully integrated into Fire OS, making it easy to manage smart home routines and apps.
Samsung QN90C – provides optional Alexa support, since you can also switch between Bixby or Google Assistant. However, it requires initial setup through SmartThings and the Alexa app. In addition, voice commands are not hands-free by default, because you must press the mic button on the remote.
As a result, the Fire TV Omni QLED delivers a more seamless Alexa experience, while the Samsung QN90C offers flexibility but with extra steps.
Smart Home Integration
When evaluating the Fire TV Omni QLED vs Samsung QN90C, their smart home ecosystems reveal distinct strengths.
Fire TV Omni QLED (Fire OS) – features a dedicated smart home dashboard with Alexa shortcuts. Moreover, it offers deep integration with Ring, Blink, Philips Hue, and Echo devices. In addition, users can launch fast Alexa routines like “Movie Night” to instantly automate lights, sound, and connected devices.
Samsung QN90C (Tizen OS) – provides a SmartThings dashboard tailored for Samsung-compatible devices. Although Alexa routines are possible, they require extra syncing through companion apps. Furthermore, while it supports advanced multitasking and app management, its voice flows feel less intuitive compared to Fire OS.
Therefore, the Fire TV Omni QLED is the stronger choice for Alexa-first smart homes, while the Samsung QN90C benefits Samsung ecosystem users.
Fire TV Omni QLED vs Samsung QN90C – Picture Quality
When comparing the Fire TV Omni QLED vs Samsung QN90C, their display technologies deliver very different strengths.
Fire TV Omni QLED – uses QLED with full-array local dimming. In addition, it supports HDR10+ Adaptive and Dolby Vision IQ for optimized contrast. Moreover, its brightness is suitable for most rooms, though peak brightness is limited to about 600 nits.
Samsung QN90C – features Neo QLED with Mini LED backlighting. Furthermore, it includes HDR10+ and Quantum HDR 32x, achieving a much higher peak brightness of nearly 1,800 nits. As a result, it delivers excellent contrast and visibility, even in brightly lit environments.
Therefore, while the Fire TV Omni QLED offers solid HDR and good room performance, the Samsung QN90C clearly dominates in brightness and high-contrast viewing.
Fire TV Omni QLED vs Samsung QN90C – Alexa User Experience
When focusing on Alexa users, the Fire TV Omni QLED vs Samsung QN90C matchup highlights clear strengths and limitations.
Omni QLED Strengths – integrates seamlessly with Alexa skills and enables routine creation directly through the TV. Moreover, it is fully compatible with Echo speakers, smart plugs, and thermostats, making it ideal for Alexa households.
QN90C Limitations – works great within SmartThings environments, but it offers limited direct Alexa automation unless paired with additional Echo devices.
Consequently, the Fire TV Omni QLED is the superior option for buyers seeking a hands-free, Alexa-first experience, while the Samsung QN90C fits better within SmartThings ecosystems.
Gaming Performance
When comparing the Fire TV Omni QLED vs Samsung QN90C for gaming, both TVs bring useful features, but their capabilities differ.
Fire TV Omni QLED – includes HDMI 2.1 on select models, which enables next-gen gaming. In addition, it offers a Game Mode for reduced latency and ALLM support. However, VRR is available only on higher-end variants, limiting advanced flexibility for some gamers.
Samsung QN90C – delivers full HDMI 2.1 support across all ports. Furthermore, it features the Game Bar 3.0 UI with detailed real-time stats. It also supports ALLM, VRR, and smooth 4K at 120Hz, ensuring a superior competitive edge for console and PC gamers alike.
Therefore, while the Fire TV Omni QLED is solid for casual gaming, the Samsung QN90C clearly excels for serious gamers who demand full performance features.

I’ve been eyeing both of these for my living room. I like the Samsung QN90C’s picture quality, but I’m wondering if the Fire TV Omni QLED would be a better fit since I already use Alexa for everything. Has anyone here tried both?
@Emily, I tested them side-by-side at a store. The QN90C definitely wins on brightness and contrast, especially for HDR movies. But if Alexa integration is a big deal for you, the Fire TV Omni QLED is way more seamless.
I agree with @Daniel. I have the Fire TV Omni QLED in my bedroom, and Alexa voice control feels natural — no extra setup. That said, if you watch a lot of daytime TV in bright rooms, the Samsung will handle glare better.
Thanks @Rachel! Sounds like it’s a trade-off between best-in-class picture and Alexa convenience. I might lean toward the Fire TV Omni QLED since I use voice commands constantly.
