"Video Converter LKV 2000", "connect laptop to TV to watch movies"

I had purchased Video converter LKV2000 to watch movies on TV from a laptop few weeks back. It worked well in the beginning and I used it for couple of weeks, but after that the images started flickering. I had to tighten the cables again and again, until it ultimately died in couple more weeks completely.

I do not know how it worked for others, but I am not happy with this product.
