Worst Picture Quality. Review on Koryo LCD TV

I have buyed this television because I have used many brands and I qant to try something different so I choose KORYO LCD TV.I have buyed it from the market at a price of 17000/-.I thought that it has great picture quality but I was very disappointed after using it.As I connected it to my digital cabel tv I have faces many problems byut any how I have made the connection.In hd channels also it has vey unsharp picture.The sound quality is poor.The color saturation of this television is very bad and the brightness is also not so good.Veiwing angle is not so good.The HDMI and USB ports are also very less.The service of this company is also bad and I cannot find fhe service centre near me.If you want to buy a television with good picture quality and great features than this one is not suitable for that.You must go for SAMSUNGas it has great features and built in quality.i am using KORYO 32DLBHN6 which is of 81 centimeters.I am not recommending this television to buy if you don't want to waste money and I am also going to return this one.
