What is the main reason why HDMI to DisplayPort adapters don’t work?

The main reason why HDMI to DisplayPort adapters don’t work is due to the fundamental differences in the way the two technologies transmit signals. HDMI is a consumer-oriented standard that is designed to transmit audio and video signals to displays, while DisplayPort is a more versatile standard that can transmit both audio and video signals, as well as data and power. This difference in design makes it difficult for HDMI signals to be converted to DisplayPort signals without significant loss of quality or functionality.

In particular, HDMI signals are transmitted using a technology called TMDS (Transition-Minimized Differential Signaling), which is not compatible with the LVDS (Low-Voltage Differential Signaling) technology used by DisplayPort. As a result, HDMI to DisplayPort adapters often require complex and expensive circuitry to convert the signals, which can lead to signal degradation, latency, and other issues.

Can I use an HDMI to DisplayPort adapter to connect my computer to a DisplayPort monitor?

It is technically possible to use an HDMI to DisplayPort adapter to connect your computer to a DisplayPort monitor, but it is not always the best solution.
