My Honest Hisense 55U6H Smart Google TV Review

Let me begin by mentioning that a prior review of my 43″ Hisense was the top review when I posted it five years ago. That’s because I kept updating that review, and I want to do the same with this one, so please keep checking back.

I give current technology four to five years (or, depending on pricing, five to six years) before replacing it with something better. That was the situation with my old TV, a Hisense that I purchased for the Olympics that year. I wouldn’t say I like Chinese items because they are designed for low cost rather than dependability. To my astonishment, my ancient Hisense is still as good as new, and a relative has inherited it since the colors and 4K technology are still outstanding.

Nonetheless, Amazon’s new low-cost FireTV television enticed me. I ordered their 55″ Omni series but returned it practically soon. If you’ve never bought a 4K TV before, this is an excellent place to start. However, the washed-out colors and lack of features (no full array dimming, Quantum Dot, or HLG) made a return unavoidable. So, for an extra $120, I went with the 55″ UH6 Hisense, which had enticed me with its payment plans and sparkling features.

I knew it was a home run when I switched on this Hisense. The color! The whites are stunning! The darkest of blacks! That’s what I’d hoped for all along, and I got it.

It took me a long time to get the settings exactly perfect. My previous settings weren’t working, as you would expect since the Hisense ULED 4K Premium 55U6H has so much more depth that you don’t need to crank up the contrast or brightness to obtain a nice image. Here they are in case they are of any use to you:

Picture \sBacklight

Automatic Sensor OFF Local Dimming High Backlight Level 100

“Dolby Vision IQ” Picture Mode


Advanced Options

Motion Enhancement OFF Color Temperature LOW

Motion Clarity is turned off.



I purchased some 8K certified HDMI 2.1 cables for roughly $22 (less on sale) to put in the 2.1 slots to obtain the greatest audio and visuals. Just make sure they are labeled “2.1 certified.” Because it is a new technology, the reviews cannot be older than two years.

I also purchased the new FireTV Cube 2nd generation to make the most of my new Hisense. It was half cheap on Prime Day, and I couldn’t have asked for a nicer co-purchase. The promotional addition 99 cent channels have brought it to life. If you want to appreciate your new TV fully, you should acquire one of the big boys: they feature the most Dolby Atmos movies and programs.

After mentioning Dolby Atmos, here’s the one major drawback of Hisense 55U6H Smart TV. Its native speakers are amazing, but if you want the complete Dolby Atmos experience, that immersive sensation you get in a theater, you’ll need a Dolby Atmos soundbar. That may cost between $400 and 900 dollars new. My still-very-good 5.1 Vizio soundbar lacks Atmos, but its Dolby Digital Plus sound is excellent. It took me a long time to realize that you must uncheck the CEC feature, or else eARC would take control and transmit audio data to my non-Atmos soundbar. If you want Atmos but don’t have a soundbar, you’ll have to settle with “TV Speakers” until you can get one. Go to a large streaming provider to check it out. If you notice the priceless double logo (Dolby Vision and Atmos), you’ve struck the nail on the head. I recommend seeing “Okja” or “Black Panther” as good test movies. The Atmos sound will take your breath away.

Detail: If you don’t have a soundbar that supports Dolby Atmos, you’ll have to rely on the Hisense TV Speakers. Navigate to “Settings,” then “Channels and Inputs,” then “Inputs.” Uncheck ‘HDMI control.’ Movies will now be heard in Dolby Atmos. Otherwise, Dolby Digital+ will be decoded.

I’ve shared several photographs to see the entire spectrum of colors available with the U6H. Check out some animal-themed YouTube channels. With your new Hisense 55U6H TV, nature films are a delight to watch. The specifics. Incredible.

As previously said, I’ll update this review as I discover information that may be useful to anyone contemplating purchasing it. Even after just one week, I can tell you that this is a no-brainer: get it.

A comparable set from Samsung with all of the bells and whistles that the Hisense ULED 4K Premium 55U6H has would set you back a thousand dollars!

Overall, the Hisense 55U6H 55″ Class U6H Series Smart TV is a top-performing TV with advanced features and excellent picture quality. Its U6H calibration, HDR support, and ALLM make it a great choice for both movie buffs and gamers. If you’re in the market for a new smart TV, the Hisense 55U6H is definitely worth considering.
