Connectivity and outputs

This section shows the types and number of video connectors on each GPU. The data applies specifically to desktop reference models (for example, NVIDIA’s Founders Edition). OEM partners often modify both the number and types of ports. On notebook GPUs, video‐output options are determined by the laptop’s design rather than the graphics chip itself.

Display Connectors	4x DisplayPort	No outputs
StereoOutput3D	+	-
DisplayPort count	4	no data
Dual-link DVI support	+	-
