If your mobile is from LG, Sony, Samsung, Sharp, Huawei, Lenovo, Acer, Asus or HTC the chances are it can be used for more than you might think.
The secret TV output
The little micro USB connector that you normally use to charge probably has MHL, which stands for "Mobile High-Definition Link". This means that you can play your videos, view your photos and listen to your music via this connector in HD quality (1080p) and with up to 8 channels of surround sound.
With the Sandberg MHL HDMI Converter Kit you can connect your phone directly to an ordinary flat screen with HDMI input.
