Logitech harmony 520

Question

will the harmony 520 work with a vizio VO22LHDTV?

Answer 1

It'll work, but won't work properly if you have to switch between HDMI outputs.

Answer 2

Yes.

Logitech Harmony remotes will work with nearly any device.

Even if they don't initially have the codes for the device you own they can "learn" the devices IR commands provided you still have the old remote to the device. This is done in the provided software. You simply aim your old remote at the bottom of the harmony and it will create a command that can be assigned to any button on the Harmony remote with the matching function.
