Our Verdict
LG UK7700
Sony X750F
The LG UK7700 is better than the Sony X750F. The LG supports local dimming to improve quality of blacks and also has lower input lag, which is great if you play video games or use it as a PC monitor. The LG can handle reflections better and you can easily place it in a bright room like a kitchen without issues. On the other hand, the Sony X750F has better black frame insertion that can clear the image blur better.
