Just got back from Cozumel but have had the same issue other places. They give you a limited remote. In this case only the channel and volume and on/off buttons worked. We brought a laptop. The TV had an HDMI input but no way to select it. Talked to IT and they said it wasn't possible, which I took to mean it was against company policy as it was obviously possible with the right settings. Not sure if the remote was limited or the programming in the TV might be limited but thinking I should take a universal remote with me. At one hotel we got them to give us the original TV remote and it worked fine. There was a setting on the TV to allow casting from a phone but never got that to work either. Anyone do the universal remote thing when traveling?
