Question about HP ProDesk 400 G5 MT

Either you have a monitor with DisplayPort and one with VGA connection, or if you have two monitors with DP this would be a possibility: Delock Displayport to 2xDisplayport Splitter (DP, 30cm) I don't know how good the image transmission is then.
or something like that: Delock Adapter Displayport male > VGA 15pin female (VGA, 12.50cm)
