I am using this television since 8 months. and when I planned to buy home theater system, the technician found that it has no audio out port. ( 3.5mm jack) . Sorry to say, but you have to work with buil; t in speakers only. They are loud but, quality is not that good. Rest: Picture quality is HD. 720p. No flicker. Reads USB. All video formats play. It also reads Subtitle files.I watch movies in full HD too. Has 2 HDMI ports, can connect to TATAsky HD. set top box. ( as in my Case) Overall good product. but, no 3.5mm Audio jack.
