Docking station upgrade x230

Has anybody tried upgrading the ports on the dock station? I'd like to convert the outdated VGA port to HDMI.

The closest thing to an HDMI port on the Series 3 Ultrabase is the Displayport++ port, which only needs a passive DP-to-HDMI dongle. It will work up to 1920x1200 IIRC.

The docking connector carries two DisplayPort++ signals, which are used as follows:

Mini-Dock Series 3: one goes to the DisplayPort, one to the DVI
Mini-Dock Plus Series 3: one goes to first DP/DVI, one goes to the second DP/DVI
Ultrabase Series 3: one goes to the DisplayPort, one unused.

So on the Mini-Docks, there is nothing that can be done - both signals are already in use; on the Ultrabase, one could tap into the unused pins of the second DisplayPort signal, and solder a proper port somewhere, which could be DP or DVI/HDMI (with a built-in passive dongle).

I bought a Display Port to HDMI adapter which I have used with a standard HDMI cable successfully on the Display Port of the X220. For some reason, the first Display Port to HDMI adapter I bought passed the video but not the audio. I bought a different brand that worked fine.

This is the one that I bought that works: Monoprice DisplayPort Male to HDMI Female Adapter
I will admit I am not crazy about the adapter sticking out the side of the X220, but it works. It would be preferable to have an actual Display Port to HDMI adapter cable.

I imagine the above adapter would probably work with the Display Port on the Ultrabase Series 3. And although I have the Ultrabase Series 3 for my X220, I have not tried using the Display Port on it.
