Amazon and Best Buy have announced an all-new series of high-end 2021 Insignia Fire TV Smart TVs for the US and Canada. What sets these apart from past Fire TV Smart TVs, and make them the new best models with regard to picture quality, is the use of quantum dot QLED technology, which is a first for any Fire TV Smart TV. These 4K TVs, available in 50″, 55″, 65″, and 70″ sizes, also support Dolby Vision HDR, which, while has been available on Toshiba Fire TVs, is a first for an Insignia model.

These new flagship Insignia Fire TVs, called the F50 Series, are the first Fire TV Smart TVs to use QLED LCD screens. While Grundig has released OLED Fire TVs in Germany, all Fire TV Smart TVs in the US and Canada have used standard LED LCD screens, including Insignia’s own F30 (4K) and F20 (1080p) Series 2021 Fire TVs released earlier this year. The advantage of QLED screens over standard LED screens is improved color gamut for more accurate colors, more vivid colors, and a brighter screen. QLED provides little to no improvement to black levels or viewing angles, which are where OLED screens excel.

In addition to improving the screen’s image quality, these new Insignia TVs greatly improve the overall appearance of the TVs themselves. Earlier this year when Toshiba released its new C350 Series 2021 4K Fire TV Smart TVs, they easily became the best looking Fire TVs in the US and Canada. Insignia’s new F50 series are certainly giving Toshiba a run for its money with much thinner bezels than Insignia’s other models, including this year’s new F30 series 4K sets. The legs of the new flagship TVs are also a nice improvement over previous models, thanks to their slimmer design.

As for specs of these new Insignia Fire TVs, I’m still waiting to hear back from Amazon regarding all the internal details, but I suspect they will mostly be the same as Toshiba and Insignia’s existing 4K 2021 models. I’ll update this article as soon as I hear from Amazon, but, as already mentioned, we do know these F50 series Fire TVs do support Dolby Vision, which was previously only available on Toshiba’s Fire TVs in the US and Canada.

Ports on these 4K TVs include 4 HDMI ports, which is one more than on Insignia’s older models but matches the number of HDMI ports found on Toshiba’s C350 Series TVs. What doesn’t match Toshiba is that Insignia still only includes 1 USB port, which Toshiba has increased to 2 USB ports on its latest models. Common on all Fire TV Smart TVs, including these new ones from Insignia, is an Ethernet port, WiFi, coax to connect an HD antenna for the built-in OTA tuner, optical audio out, 3.5mm headphone audio out jack, and composite RCA video in.

The included remote is the same Alexa Voice Remote that comes with all of Amazon’s latest Fire TV Smart TVs and Smart Soundbars. This remote was introduced last year and comes with a few improvements over the older Fire TV television remote, such as the addition of a “Recents” button and “Settings” button, plus just overall better button placement and layout. While the top two app buttons will be for Prime Video and Netflix, the bottom two change frequently enough that there’s no way to be certain what app they will be for before purchasing. However, they can be remapped with my Remapper app.

Insignia’s new F50 series Fire TV Smart TVs are now the best models in the lineup, thanks to the use of QLED screens and support for Dolby Vision. They are listed on Best Buy’s website as “Coming Soon” in sizes of 50″ for $599.99, 55″ for $649.99, 65″ for $799.99, and 70″ for $899.99. They will also be coming to Amazon.com in the near future, where you’ll be able to order on Amazon and pickup in store at Best Buy if you’d like, which is a service that has recently been expanded to include all Best Buy stores in the US and all Fire TV Smart TV models.
