I have been enjoying movies, sports since last year on my samsung led j4100. I have not found any issue yet. It is fully packed with great features.
Enlisting some of the features that I liked the most:
Sports mode is the most amazing feature of this tv in which the colors and contrast are set automatically ensuring the best viewing experience for sports.
It has downfiring speakers which are sufficiently loud. It supports DTS sound and the speakers also have a good bass. Hence, there is no need to buy an extra pair of the speakers.
Apart from this it also has 2 usb ports, with the help of which you can even transfer data from one usb to another.
Moreover it has family tv feature, through which you can record sound( anything running on the tv), take screenshots and a story replay is also there.
Conclusion: It is a good value for money product. You will be happy like me after buying it.
