Installation: Plug and Play，Rejection Delay Specifications: Input: USB Type C Male; Output: HDMI Female；Supports video output only, no audio! This usb c to hdmi adapter is only compatible with the devices whose c port supports DP Alt mode . No Delay, Large Screen Viewing Important Notes Cable Selection Guide This adapter supports a maximum output of 4K@30Hz . For optimal signal stability, it is recommended to use an HDMI 2.0 cable (supporting 4K@30Hz/60Hz, 18Gbps bandwidth, and ≤3 meters in length). While 8K HDMI cables are backward compatible, their higher specifications may occasionally cause signal instability. Using a cable that matches the adapter's specifications is strongly advised. Some apps can't project videos to the screen due to copyright protection reasons !!! About iPhone 15 Series 1. Screen mirroring maintains the phone's vertical orientation on the display (no automatic adjustment). Some landscape-supporting apps may show black bars if aspect ratios differ. 2. Screen turns off, monitor disconnects; Apple's native apps (e.g., Apple TV) can stay connected when running in the background. Compatible List (Not a full list) Confirm device support for DP Alt Mode!!! Quickly Assess Compatibility Review: A solid USB-C-to-USB adapter - Well-built. Does the job. Review: works - Works with my android phone (with symmetrical shaped plug) but disappointed that I can't turn the display / screen off while using it on my tv like I can with Spotify and with anything on my laptop... but that's not the product's fault. My old computer couldn't update to use Netflix on it anymore. Works with my new mac computer. I like that it doesn't light up or flash at all! (But disappointed there's a red dot on corner of tv screen when using hdmi cord to hook up to computer -- but I'm pretty sure that's the computer's fault.) I really wanted to try an adapter that wasn't a cord at all with multiple types of outlets but felt iffy from reviews, stuff like 'it always has a light and is draining power even when computer isn't awake' -- so I went for this for now. I like that it's just a little cord to adapt it, without a box thing hanging off, seemed like that could cause problems or be more annoying. ## Features - 【USB C to 4K HDMI Adapter】Offering 4K resolutions up to 3840x2160 at 30Hz.

If the A12 has a USB-C connection there is a good chance it will work. **Q: Will this work for my switch lite to connect to my tv using the hdmi?** A: No, the USB C to HDMI Adapter does not work with the Switch lite. **Q: will this adapter work to hook up my phone to my roku tv. where we camp there is no wifi. i have a galaxy s9 thru verzion** A: I can not speak specificilly for the S9 but I have a S21 Ultra and it works like a charm - Highly Recommend. Also works great on my MacBook Pro. I often work at my place in WV and there isn't any viable wireless options, so I use my S21 (previously my S8) to stream content and as a hotspot. You could do the same thing with your Roku tv and stream through your phone or use the Roku functionality on the TV. That said, this adapter works extremely well for streaming from an app on your phone directly to your tv via HDMI. NOTE: (I had to do this) In order to get your S21 (and very likely the S9) to display on the tv in Full screen, there is a Display setting that needs to be updated on the phone. Under the Display option in Settings you need to enable the app in question under the 'Full Screen Apps' option. Enable the App in question to display the full screen on your tv and you are good to go (at least this is how the feature works on the S21). **Q: Will it work with moto g stylus 5G (2022)** A: The key elements to this working are that the phone or tablet in question have a USB-C port (the moto g probably does) AND that is supports "DP Alt Mode". This last one is tricky because not all phones support this and not all phone specifications say whether they do or not. You're probably best off going to the Motorola support page and asking the question there. ## Customer Reviews ### ⭐⭐⭐⭐⭐ A solid USB-C-to-USB adapter *by D***C on January 27, 2026* Well-built.
