In search of a certain kind of display...

Hi,

I am looking for a certain kind of display:
The LCDs useally combined with the beaglebone black are capes: They
are attached directly to the bbb.

I put my bbb into a case of the size of an Altoids tin box.
Since it is made of solid metal and painted black I dont want
to drill holes etc in it.

My BBB is setup for headless and mobile useage.

Now I am looking for a display, which can be attached via USB/LAN/???
to the bbb. As a last resort I would choose HDMI...but I really dont
like to do so, since it blocks ports.

Is there any display of such kind, which is known to work with the
bbb?

Thank you very much in advance for any help!
Best regards,
mcc
