full hd mean 1080p supported, aka 1920 x 1080 resolution. HP w2228h max support 1680 x 1050 so it is hd ready. w2448h is full hd

nothing new about HDMI except it backward compatible with DVI and combine digital audio signal(up to 8 channel, 24-bit sample size and 192kHz sample rate) in the same cable. and signal between dvi and hdmi are same so there exist dvi to hdmi converter. google and wikipedia is your best friends.
