The ELSA SYNERGY II issues analog signals in accordance with the requirements of
Guideline RS-170. The synchronization information is sent separately. If your monitor
provides a switch for the input impedance, you should select '75 Ohms' (= '75
Ω
') for the
R, G and B video inputs and '2 kOhm' (= '2 k
Ω
') for the sync inputs. You should only try
other switch settings at the sync inputs if your monitor expects sync levels other than
those used by normal monitors and does not produce a stable display. The switches are
labeled “Low” and “High” only on some monitors. You can then refer to your monitor
manual to find out what input impedance level this refers to, or you can experiment to
find a position in which a stable image appears in all graphics modes.
