Hi, I saw someone else asking almost the same question and didn't get an answer. Another user recommended putting the post in this forum. Hope that is okay. I have Droid MAxx KitKat vs. system 21.11.21 (the newest phone). I used to have the first Droid Maxx which had a separate HDMI port. I would just plug in the special HDMI cord from the TV to my phone and mirror my phone screen to my TV. For my new Droid phone, I bought a C2G® SlimPort 0.2 m USB Micro-B to HDMI Adapter. Plugged it into the phone and into the HDMI cable from the TV last night and nothing happens. I also have an Ellipsis 7 Android tablet with the same type of connection, tried plugging it into that...nothing. It seems kind of crazy that Android would take away the mirror screen ability. Am I missing something? Why do they sell the adapters if they don't work or do I have to use an app. Is there some setting I need to change on the phone and the tablet? Any help would be appreciated. If I can't figure it out, I have to return the adapter to the store. Thank you.
