OK are you talking dual external displays (would require a docking station) or one external extended display plus the laptop ? The later will run from an HDMI port. (and I have a box of HDMI, VGA, and DVI adapters). I do show the S5-371 as having a
• HDMI® port with HDCP support
I do not have a S13 but have both a Targus and a Mediasonic docking station either of which allow me to run two external displays, both "extended". Plus another display from the HDMI port, plus the internal display on any of my portable devices including a W510 tablet, SW12, and R11.
