HDMI setting issue

For some reason when I go to the video settings and try to change HDMI-auto to 1080i that option shows up but when I hit OK it goes back to HDMI-auto. I use an HDMI cable. When I try to change the settings using the composite cable I don’t have the options for any change. I need 1080i for my wireless setup and can’t get it. Will a firmware upgrade change this issue? Thanks!

Update. Never mind.  Just realized you have to choose 3 settings (color etc.)  before you can change the resolution.

Can you please specify how you got it solved? What other settings you changed before you can select 1080i?
