It is unclear if there exists a wired connection on this 22 inch LRD TV.
A RJ45 plug is located at the back side of the TV.
Further more I did plugin an ethernet cable from an ADSL-router.
Result: on the screen the following messages are to read:
"The TV is connected to the home network" and you need "mediaserversoftware".
Where to find and how to install that software item?

Furthermore on a PC also connected to the ADSL-router (192-168-1-254) displayed:
IP-address active and that is the TV.
However my question is to make a data connection between TV and PC?
