I still can't see the need for a universal remote but if it works for you it probably make it faster than fussing around with the toggle switch,
Here is the plug in adapter my husband made to plug in the HDMI cable.
You could use 1/2 inch pvc but he used some scrap 1/2 inch cpvc since is was a little thinner. Once you insert the cable into the cpvc you can easily push it into the socket and then remove the adapter.
Of course he had to paint it. 😄
