Incompatible adapters are being used.
There has been some confusion when using HDMI to DisplayPort (DP) or the opposite way adapters on Dell computers. There are two types of conversion adapters that can be used, the first is an active adapter, and the second is a passive adapter type. Most adapters only carry a one-way signal.
What is the difference between a passive and active DisplayPort converter?
When you convert video from a source that uses DisplayPort or Mini DisplayPort to DVI or HDMI (ex: A computer to a monitor). Consider the difference between passive and active adapters.
If the source supports dual-mode DisplayPort (also known as DP++), then you can use a passive adapter because the source can perform the conversion. If the source does not support DP++, then you must use an active converter, which includes additional chips to perform the conversion.
Thunderbolt ports support DP++ natively. To run multiple monitors from the same computer, see the Active Adapters section below.
