HDMI Version Number

I've been having trouble with my Mini on an older TV I have where occasionally the picture and audio will drop for a second or two. I think it might have to do with the HDMI port on the TV which is 10-15 years old. Does anyone know what the HDMI version number is on the Mini? I can't find that info online anywhere. The TV is most likely version 1.0 - 1.2.
