This is a 60Hz panel.120Hz is with "smoothing" enabled.It cannot display a 120Hz input nor can it accurately display 24FPS content without 3:2 pulldown and judder. The internal FireTV implementation does not support output of 120Hz for Fire TV games. This is an Amazon Fire TV 4K device (based on the NFQ design). It would have to be a 4K Plus (ZTT) or 4K MAX (VH9)-based device to support 4K120 internally. Native display: 60HzInputs: 2.0, limited to 4K60Internal: embedded HDMI, limited to 4K60Fake nonsense marketing refresh rate with soap opera effect enabled: "120Hz".

This Toshiba 75 inch M550 is a budget QLED Fire TV that stands out for full array local dimming, a built in subwoofer, and solid gaming support at 1440p and 120Hz with VRR on Xbox and PlayStation. The panel is still a true 60Hz display, so 120Hz only works in limited gaming modes and not at 4K. Fire TV software is also described as slow, making an external streamer a better fit. A useful pick if you want strong picture features without paying for a higher tier set.

  • The TV supports VRR with Xbox and PS5 at 1440p with 120Hz output.

  • The Toshiba M550 model reportedly continues working well after years of use.

  • Local dimming works well and blooming stays minor during normal content playback.

  • Using an external streaming device can improve responsiveness compared with the onboard Fire TV software.

  • The panel is reportedly a true 60Hz display, while 120Hz behavior is limited to smoothing.

  • The TV reportedly cannot display a 120Hz input and may struggle with 24FPS accuracy.

  • Fire TV software reportedly runs slowly, which can hurt day-to-day usability.

I purchased the Hisense, but the Toshiba is better, local dimming, more ports, higher brightness.

The Best Buy 5-year warranty costs $79 vs. $33 at Walmart, since I think the warranty is a must with these cheap BF TVs, the price difference is more like $68 instead of $22.

I got it in last weekend, Xbox and PS5 allow for enabling VRR and 1440p @120. On Xbox you have to actively disable 4K as it will just switch back to 4k 60 otherwise. Once it's setup that way it's definitely smooth like you'd expect from 120.
Local dimming works great, you can tell it's only 48 zones as it blooms a bit when you play test videos but that's not noticeable with normal content.
FireTV software on this TV is very slow, be sure to use one of the HDMI ports for a proper googletv/onn4k/appletv/firestick. I don't recommend using the onboard FireTV software.

The guy at Walmart told me there were some 75" QLED Vizios in the back for $328 that were coming out for Black Friday.
So, depends on what you consider a deal, but for the lowest price wait and be ready to get up early for door busters.

I'm looking at the same decision. I was waiting for the 75u8n to drop in price again but it didn't. Going to pick up a bedroom tv to use as main until that happens.
How decent is the Toshiba if I hook an Onn Google TV up to it?

Full array local dimming on the toshiba, and a built-in subwoofer as well. This Toshiba is a Hisense, sitting somewhere between a u6 and u7.

Mine just got delivered. I got the last one in Arizona
