Some high-end monitors and video cards used multiple [[BNC connector]]s instead of a single standard VGA connector,{{which|date=April 2021}} providing a higher quality connection with less crosstalk<ref>{{cite web|title=What is the VGA connector and how to use it|url=https://blog.tyfontech.com/vga-connector-use/|access-date=26 July 2022|website=Tyfon Tech|date=8 February 2018|language=en}}</ref> by utilising five separate 75 ohm [[coaxial cable]]s. The use of BNC RGB video cables predates VGA in other markets and industries.

Within a 15-pin connector, the red, green, and blue signals (pins 1, 2, 3) cannot be shielded from each other{{clarify|date=May 2025}}, so crosstalk is possible within the 15-pin interconnect. BNC prevents crosstalk by maintaining full coaxial shielding through the circular connectors, but the connectors are very large and bulky. The requirement to press and turn the plug shell to disconnect requires access space around each connector to allow grasping of each BNC plug shell. Supplementary signals such as DDC are typically not supported with BNC.

Some laptops and other portable devices in the early to mid-2000s contained a two-row mini-VGA connector that is much smaller than the three-row DE-15 connector, as well as five separate BNC connectors.
