Default [Q] HDMI ICS(720P) vs JELLYBEAN(1080p)

I have two Motorola Photon Q's
One is running ICS with SIM MOD.
The other is running Jelly Bean with No SIM MOD (Spare Parts Phone)

Does ICS only support 720P? That is the resolution I get when I plug the HDMI cord in.

My Jelly Bean (Spare Parts Phone) supports 1080P when the HDMI cord is plugged in.
