My monitor requires VGA, and I would prefer to use Displayport, as I have already bought a faulty HDMI > VGA adapter.
Wait, so your monitor only has a VGA input? What resolution is it?
Also the thing with display port is that the connector itself (output) is powered, so unlike some other standard you don't need an expensive powered converter, so yeah any of those ones in the link will be fine for DP (Out) to VGA (In)
However when going the reverse route (VGA Out to DP In) you need to get a powered converter, which are like £50-100 lol
