There are no adapters available from Roku. I have seen 90 degree HDMI adapters, but my suggestion would be to instead use an HDMI extension cable. This way you have more flexibility in placing the Stick, for improved cooling (the Stick does run warm) and perhaps getting a better WiFi signal. Sometimes the TV emits some RF that might interfere with the Roku, so getting it further away from the interference is again a good thing. Here's one at Amazon, a 3 foot cable for a bit over $8. I've used Amazon Basics HDMI cables for years without a problem, even at 4K resolution. https://www.amazon.com/AmazonBasics-High-Speed-Female-Extension-Cable/dp/B01D5H8ZI8?th=1
