I have a very old laptop that still has a working DVD player and can play digital movies. All it has is a standard monitor port and this device works great. The screen quality was very good and the sound quality was perfect once I figured out the headphone jack. No instructions were included, but I finally figured out that you connect the device's headphone jack to the laptop's headphone jack. Do not connect the device to a TV as this will not work. The power cord that came with the kit was not needed, I don't know what it is for. Once I realized I had plugged the device into my laptop's headphone jack, the sound was perfect. Great product for those who have an old laptop that can be used as a media player.
