I have problems finding MHL cables in Singapore for my Galaxy Nexus. MHL stands for Mobile High-Definition Link and here is the definition from Wikipedia:
Mobile High-Definition Link (MHL) is a proposed industry standard for a mobile audio/video interface for directly connecting mobile phones and other portable consumer electronics (CE) devices to high-definition televisions (HDTVs) and displays. The MHL standard features a single cable with a low pin-count interface able to support up to 1080p high-definition (HD) video and digital audio while simultaneously charging the connected device.
It is essentially a Micro USB to HDMI cable. Since I could not find it in Singapore, I tried sites like Deal Extreme and Amazon. The MHL cables being sold at Deal Extreme cost about US$15 with free shipping which is not exactly that cheap. I saw one from Amazon (Samsung MHL to HDMI Adapter – Data Cable – Retail Packaging for AT&T SGH-i77 & T-Mobile SGH-T989) which apparently is made by Samsung and it cost only US$17.58 (at that time I bought it) and shipping cost an additional US$11.99. Ended up paying US$29.57 (S$37.20) for it.
Placed my order on the 17th March 2012 and I received it on the 29th March 2012.
Samsung has a huge presence in Kuala Lumpur, Malaysia, much more than Apple. While I was in Kuala Lumpur for my birthday weekend, I went to the Samsung store in Plaza Low Yat and they are apparently selling it for about S$44.
The MHL cable comes with two ports, one for the HDMI cable and the other is a micro USB port for external power. For some reasons, the cable only works when I used the charger provided by my Galaxy Nexus package.
Once connected, your Galaxy Nexus will automatically be switched to landscape mode and your television will be mirroring the screen on your phone. Do note that the mirroring of your phone forces your television to use the resolution of your phone.
