The Hisense U7G generally offers better performance for gaming due to its higher refresh rate and lower input lag, making it suitable if you are a gamer. It also provides better dark room performance, which is advantageous for watching movies or streaming content in low light conditions. Conversely, the Sony X77L typically costs less and has better out-of-the-box color accuracy, which may be preferable if you prioritize color fidelity without additional calibration. However, it is not as well-suited for dark room viewing or gaming compared to the Hisense model. Both TVs are suitable for watching news, sports, and animations, but if you often watch TV in a sunny room, both have adequate bright room performance, although the Hisense U7G has a slight edge.

Milton Clark | September 2023
"For an entry-level model, Sony’s X77L is a decent 4K TV. It’s color reproduction, along with crisp and clean picture images revealed plenty of detail and clarity thanks in part to Sony’s excellent video processing."

About Hisense

Hisense, a Chinese TV manufacturer, entered the US market in approximately 2011 and has since acquired TV divisions from various companies such as Toshiba, Sharp, Hitachi, and NEC. Currently ranking as the fourth largest vendor in terms of sales volume, Hisense aims to capture a wide range of TV budget segments. They offer exceptional value with TVs that often outperform their competitors at similar price points, making them a compelling choice for consumers. In the US, they use Google TV as their smart TV software which provides the largest app selection and a very modern user interface, however it is not as user friendly as the software from other vendors.

About Sony

Sony stands as a highly experienced and widely trusted TV manufacturer, earning a reputation that surpasses all others. A Japanese company, Sony has been making TVs for far longs than it has been making Playstation game consoles. Sony's high-end TVs are often regarded as the ultimate choice for videophiles, representing the epitome of quality, albeit at a premium price point. Renowned for their advanced and precise motion handling, as well as their cutting-edge local dimming algorithms, Sony consistently delivers unparalleled performance in these areas. They include Google TV software with all their TV sets, which grants access to the largest selection of apps available and they also include Bravia Core which is a movie streaming platform specifically for Sony TVs that offers higher picture quality by using more bandwidth.
