If you want wired, you can also use HDMI to Ethernet such as this Digital HDMI Extender By Single Cat 5E/6.
A good option, Cat5 even with connectors on do not require a big hole although the "mini HDMI" end is about the same size as Cat5 ends..
Folks do need to be aware that some of these extenders are "passive" or draw power from the HDMI ports to avoid the need for external power supplies..
Passives and phantom ones that draw power from the HDMI ports tend to fail much easier than ones requiring an external supply..
Had this issue with connecting remote PCs to projectors mounted from the ceiling. Went through a few passive extender failures until I replaced with ones with external power supplies.
The one 1492 posted does require the use of the included power supplies which should be more reliable.
