ThinkPad T420 DisplayPort Version Number

Quote

#1 Post by _ThinkPad_ » Wed Dec 18, 2013 4:28 am

To all ThinkPad experts:

1. Is the DisplayPort on the ThinkPad T420 with NVIDIA NVS 4200M (Optimus) version 1.1, 1.1a, or 1.2?

2. Can the version number be verified anywhere in Device Manager (Windows) or any third-party utilities?

Thank you in advance for your answers!

Hi folks,

I have a question regarding connecting the T420 to a TV.

Can I just buy one cable from the T420 Displayport to the TV HDMI?
