    Sharp, clear, decent contrast

    One thing that has become common in pretty much every smart TV these days is that the home screen is now a new advertisement space and they want your data. So, it’s not like this TV is out of the ordinary on that, but everything seemed like it was “Sponsored” as you try to find what you are looking for and there are several data collection and privacy settings that are on by default. Once you get it set up, I recommend going into preferences and disabling a lot of those, unless you like the data collection for customization. Out of the box, this TV is slightly thicker than other TVs I have had in this size range, but who is looking at it from the side. Picture quality on this TV is really nice. The anti-reflect screen and the ULED tech really give it bright colors and decent contrast. I’m actually kind of shocked at how little blooming there is when testing it out in high contrast situations. However, the local dimming options really start to mess with the image and create some very odd half lit areas. Making some situations look way darker than they should. I found leaving the local dimming off gave a more consistent image, especially in high contrast situations. The viewing angle on this TV is also surprising. Many get drastically washed out the moment you are at any angle from the center. However, there is some noticeable difference, it is not so drastic that it becomes unwatchable. I tested from about 60 degrees off set and could still make out everything. Being that this is a Fire TV, you have all the digital providers that you can think of. You can connect with 5 Ghz, 2.4 Ghz Wi-Fi, or Ethernet cable. With an Amazon account you can connect to Luna games and use your phone as a controller or connect a Bluetooth controller., There is Prime video and photos to make it a picture frame too. All while using Alexa features straight from the remote. You still have basic coaxial, and 4 HDMI ports. Two of them are 4K@60hz and the other two are 4K@144hz, which are great for PC or gaming consoles. Just make sure you are using the right port if you are looking for that higher refresh rate. Also, change the picture mode to “Game” so that it removes all the added processing. The different picture modes really change things up so you might mess around in there to find the perfect setting for you. Having “Light Sense” enabled looks drastic the first time I enabled it, but realized that it does pretty good for the environment. Like turn on the lights and the TV gets brighter, turn them off and it softens so as not to strain your eyes so much. Overall, I really do like all the options this TV has to offer. The quality is sharp, colors vibrant, contrast doing better than most LED, but not as good as OLED, still much easier on the pocket comparatively.

    Bang for the buck

    Great value for a 144hz tv. The ambient sensing features leave a lot to be desired. Manually configure brightness/dimming/color/etc for best results.

    Really Great Viewing

    I requested the Hisense - 55" Class U6 Series Mini LED QLED UHD 4K HDR Smart Fire TV and when we do so the product is then shipped directly by the manufacturer to me. So, I am at work when this was delivered and my husband called to ask me what had just been dropped off at the curb on a wooden crate enclosed within a wooden box. Since I had requested this item in March of this year, I did not recall. This item had been shipped via a trucking company as freight vs. the standard FedEx type of delivery. Bottom line, this television was very well packed first in its own cardboard box then enclosed in a wooden box, arriving intact without any issues. However, if you purchase this in the store, I assume that you will take it home in the cardboard box, but if shipped through an online purchase who knows Now, why was I interested in ordering this item. I am a big Fire TV stick user and have them on all my smart tv's, no matter the televisions' manufacturer. Yes, I have the ability to download the various streaming service apps, but I like the way that Fire TV organizes my viewing choices and allows me to order my apps, in addition to making recommendations on content across various outlets. What I did not realize, silly me, at the time of ordering this was that the television is essentially programmed internally with a built-in fire stick and that its remote is an actual Fire Stick remote. So, if you are familiar with having purchased the Fire stick/remote combination, the stick part is now programmed in the tv and the remote is the only accessory inside the box. For now, I have this sitting on a surface and not on a wall mount. That means that I had to use the TV base and screws in predetermined holes, also included in the box. The quick setup guide recommends that this a 3-party job, but in my case, the 55" inch took 2 people as you must place it on its back to be able to access the bottom to attach the base. I had read that some people on a prior year's model had had problems linking this television to their Amazon Prime accounts, however, for me the linking was seamless and it even prompted me to choose which fire stick on my account to mirror in the set up. No problem there for me at all. I also did not connect this to a separate sound bar, but in my opinion the audio is clear and distinct. The picture color and sharpness are vivid and quite dynamic and for this price point I feel that the buyer is really getting good value. I also want to share that this Fire Tv has a newer feature built in which is called the ambient experience. This feature will revert to a screen saver of sorts, like art in a frame on your wall or tabletop while the television is on but not in use for content viewing. The user can then program what kind of "art" that they wish to display, and set it up as a slideshow, picking the time interval that it changes to another picture within that art type. I picked the artist Claude Monet, a French impressionist painter. To recap, this is a total package with the Hi-Qled MiniLed, glare-free /anti-reflection screen and Dolby Vision-Atmos creating a very dynamic picture quality and vibrancy, as well as good sound right out of the tv's speakers. I do recommend the purchase of this television.

    Great TV

    The picture quality and brightness is spot on! A key plus is the screens matte finish that keeps thr reflections in a bright room from impacting viewing. It’s great for gaming and the artwork screen savers is fantastic. Can’t beat what you get for this price.
