Let the hive mind of Engadget get that for you.
"I've found myself using my PC for a lot of conversations lately, and I'm also considering recording a podcast to share with anyone who will listen. There are tons of USB headset / microphones out there, and I'm hoping someone has some solid recommendations based on experience. I'll consider both headsets and standalone mics, by the way, but I'd like to keep the bill under $100 if possible. Help!"
I stand corrected, let me say you learn something every day. I was reading http://www.pcmag.com/encyclopedia_term/0,2542,t=HDMI&i=44161,00.asp and HDMI spec http://www.hdmi.org/download/HDMI_Specification_1.2a.pdf. HDMI devices do detect if it is DVI or HDMI and can determine what they want to do. I just have never heard of a device forcing HDMI. New wrinkle that hopefully will not spread.
