What is a significant drawback of using 5-wire RGBHV instead of a VGA cable?

Increased cable length requirement
DDC will not pass along RGBHV 5-wire
Lower resolution capability
Incompatibility with older devices

The correct answer is: DDC will not pass along RGBHV 5-wire

Using 5-wire RGBHV presents a significant drawback in that DDC (Display Data Channel) signaling will not pass along a 5-wire RGBHV configuration. DDC is a communication channel that allows the display to communicate its capabilities and specifications, such as resolution and refresh rate, back to the graphics source. VGA cables, which typically carry RGB video along with horizontal and vertical sync signals, also support DDC, enabling this two-way communication. When using 5-wire RGBHV, which separates the sync signals and does not include the DDC signaling capabilities, this essential feature is lost. As a consequence, devices connected with 5-wire RGBHV may not be able to automatically adapt to the best resolution settings offered by the display or provide feedback on the display's capabilities, potentially leading to sub-optimal performance and connection issues that might require manual config adjustments. This presents a practical limitation for setups that rely on automatic configuration for optimal operation.
