As thin as this screen is, there’s more to it than meets the eye. As number 2 in the Best 70 Inch TV buying guide, this smart TV has built-in features in the form of Alexa and Google Assistant and has support for both Android and Apple features. Find out how the best TVs work through this review.

Why We Like It – LG OLED77C9PU

As part of the LG C9 series, this OLED TV has great sound and picture quality. This wide smart TV has add-ons such as Apple Airplay 2 and Android TV and has the option to browse the internet and download entertainment apps. For a smaller 65-inch option, you can check out our Samsung 8 Series TV review.

  • 4K Resolution
  • 4 HDMI ports
  • Can be used for gaming
  • Flat screen instead of curved
  • Capable of screen burn-in
  • Expensive


This LG OLED TV graces the viewer’s eyes with a modest refresh rate of 60 Hz, eye-catching contrast levels, and ultra-high definition. The sound quality is amazing due to having a Dolby Atmos 2.2 Channel Speaker System. While both have access to the Alexa assistant and Netflix, Sony X950H doesn’t have the Internet browsing capabilities like the OLED77C9PU does, and unlike the Vizio P-series Quantum TV, it allows for downloadable apps and has Bluetooth.

This 77-inch TV weighs 74.5 Lbs., making it lighter than the 75-inch Samsung UN75TU8000FXZA. The TV also has built-in speakers and an impressive assortment of ports: USB, HDMI, Ethernet, and audio in/out. However, it uses an OLED screen, which is susceptible to screen burn-ins, and while those can be avoided, some methods include either not using the TV too much or making sure that things on the screen move every once in a while.

OLED TVs are more expensive than their QLED counterparts, and the bigger the screen, the more apparent that observation is. Combining that with add-ons such as Alexa and ThinQ would make the TV cost $2,000 at the least. Unless the viewer is able to avoid letting the TV get screen burn-ins or can even reverse them, it’s too expensive for features that are either capable of being tedious to maintain or may not even last long enough before it needs maintenance.


There are so many customizable features and options. However, one of the more essential features, the TV screen itself, is able to develop screen burn-ins. One way screen burn-ins can be avoided is by not using the TV too often, which defeats the purpose of a high-quality TV as viewers would want to use it more often.
