A:AnswerThis is a thunderbolt to hdmi adapter that you would use for an Apple PC. What you want to find is a lightning to hdmi adapter. This kind of sounds like I’m making a joke but really. Here’s an example of what you’re looking for that Best Buy sells. https://www.bestbuy.com/site/apple-lightning-digital-a-v-adapter-white/7007013.p?skuId=7007013
A:AnswerI do not have a Samsung S 10. However, I don’t think that it will work. I use this to connect an old MacBook to HDMI and it works great, but my guess is that you need a different connector probably something related to USB, but I don’t know.
A:AnswerThe ports on your MacBook are called USB-C. Mini DisplayPort is different from USB-C. You will need a USB-C to HDMI adapter to connect your MacBook to your TV.
