I am very happy with this TV. Whether, I am watching movies or listening to music on it, it is a whole new experience for me. It is way smarter and better than my old one.. I specially liked its picture quality, its fabulous and looks amazing on my wall.

USB works great.Even 1080p mkv files were played smoothly.
flv,avi, etc also works. SD picture doesn't look great.Overall agreat package if you plan on seeing HD videos via usb.(only FAT32 works NTFS doesn't so please convert it before using usb hard discs)
