I bought this part and it didn't work for me. But you can still try it and if it doesn't work, the support will certainly help you (the item was credited to me). See also here:

@Lehedinge:
This adapter is designed to connect a notebook/PC with a Displayport output to a monitor that has an HDMI input. If, as your question suggests, your monitor does not have an HDMI input, then this adapter is of no use to you.
You should already say what signal type / input socket your monitor has, otherwise we can't help you here.
