2011-12-08, 7:35 AM

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

http://www.newegg.com/Product/Product.aspx?Item=N82E16815296009

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,

Same here. T420s, DP>HDMI cable, tried on several tv sets and it does not detect any of them. Does anybody knows what the problem is?

@davidjohnson666 and orlic,

Ensure you have a compatible DP -> HDMI adapter. There has been several thread on this which you can find here. Several users have suggestion adapters from ebay which works. You can also get a compatible adapter from Lenovo Shop (Siig adapter)

*Non Lenovo employee*

I have a Y530 ... Feel free to highlight any post which you have posted on the forum to me if no one have chimed in.
