    I have heard that displayport on some systems in the past have not supported audio out via displayport-to-hdmi converters.

    I purchased this adapter:
    Displayport to HDMI, and connected it with a cheap HDMI cable to my Toshiba 42" LCD TV.

    Windows 7 automatically detected it and passed audio to the TV.

    Does anyone know if the display port on the x220 and x220t will pass audio via an HDMI converter?

    The X220 should handle audio over the displayport (which means the HDMI should contain an audio stream too when using the correct adapter). The reason that the X200, R500, T500, W500, X301 did not support audio was due to hardware limitation, which was addressed in the subsequent Thinkpad release.

    I picked up this adapter Newegg.com - BYTECC AP-DPHDMI-005 DisplayPort to HDMI Cable Adapter 0.5ft (6") w/IC up and it did not pass any sound to my Sony XBR 40". The video was also not correctly proportioned for the screen (chopped off outside edges). I went through all the audio settings and found nothing that referenced HDMI. I connected another notebook that had a full HDMI connection and it worked fine (audio, video, correct proportions) so I know the TV was ready for the signal. Any suggestions.

    BTW, I love the T420 and appreciate the discussions on this site.

    Funny, I remember reading this thread a some days ago, but couldn't find it this evening. Turns out I just ordered the same thing a few minutes ago along with a 10 ft. "BlueRigger High speed HDMI cable from amazon.com - the price for both shipped was under $20.

    I had looked earlier in the day at Micro Center (brick & mortar), and the adapter alone was $35! :eek:

    Yeah, that adapter is a great deal, another reason why I love Amazon.
