Recently I bought a new T420, want to use the displayport port connect with my HDTV using displayport to HDMI adapter+HDMI line to my TV. But it not work. the adapter is GWC Tech. AY1200. THE HDMI line works well with my another thinkpad HDMI port.
Adapter is bought as following link from newegg.com
My T420 only have one displayport, first time I connect them, they do work for around 5 second, then both screen turn dark and no signal show in my TV and my pc return to normal. No signal show in my TV. Some one can help me with my problem? I need to setup some parameter in my computer? Thanks,
