The 997 is (was) marketed as being HD technological advantage.
Are you asking if the upgrade will improve your screen resolution?
997 are an older unit and not in production any longer with the 998 replacement.
It is even hard to find a 997 out in the stores.
HB does not list the 997 on its page. Even the legacy page does not show the 997 or the 1197 any longer...
Harry, or Robert..... you have the 997 can you weigh in on this?
