    Well worth the purchase

    My wife and I recently purchased a home (we're still furnishing), and we needed a sizable, reliable, and high-quality living room to entertain guests. After several hours of research, we decided to get the Hisense 55'. It did no disappoint! The price point was reasonable, but the product exceeded our expectations! Clea, crisp, screen, good quality sound, and a good addition to our still not finished living room. Highly recommend.

    Great audio and picture quality

    This is the first time I’ve gotten this brand and I really love it. Easy to set up and use. Sound is loud which is good. I’ve had other brands where I have to turn the volume all the way up to hear clearly when theres background noises. Picture quality is great too. Will most likely buy another Tv for the living room soon.

    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.
