Indicates how many separate monitors can be connected to the card at the same time. The limit is determined by the chip's internal display units and the data throughput of the outputs. Some DisplayPort connectors with MST or select USB-C connectors can fork the signal to serve more panels than there are physical ports. Conversely, a demanding configuration - like 4K at 144Hz - will use up almost all available capacity, so the card will only activate two monitors instead of the claimed three, for example.
