Connecting Galaxy S3 to DisplayPort via MHL HDTV Adaptor I have a Samsung Galaxy S3, and I just bought the Samsung HDTV Adapter (MHL to HDMI). However, my Dell U2412M monitor only has VGA, DVI or DisplayPort. So I also bought an HDMI to displayPort converter cable. Alas, the connection doesn't work.

I know that everything is properly connected. The Samsung MHL is properly connected to both the phone and the (official Samsung) charger. The HDMI cable goes from there to the displayPort to HDMI (female) adapter, which in turn is properly fitted to the monitor. Then, I switch the input on the monitor to DisplayPort, and sadly my monitor goes to power save mode.

Is there anything I can do to make this configuration work? If not, have you got any advice?
A few things to consider:


Make sure the HDTV adapter is connected to a USB power such as the wall or a PC (the USB from the TVs don't give enough power)
Have you tried the HDMI to display port adapter with another HDMI output such as your laptop or PC? maybe this is faulty
Try using an HDMI to DVI adaptor
Try another HDMI monitor to ensure its not your monitor
