Its hard to imagine a time when hotels TVs didn't feel vestigial. Not all that long ago, some made their TVs a selling point, plastering free HBO all over their roadside signs. These days, guests are more likely to stick to their phones, sacrificing their rooms beautiful 48-inch flatscreen on the altar of TikTok and YouTube. But with just a little extra work, you can get the best of both worlds and cast whatever is on your phone to your hotel room's smart TV.How to cast your iPhone to a hotel TVThere are official and unofficial options to send what's on your iPhone to a TV. Lets start with the most legit.Use AirPlay (provided your hotel supports it)iPhones can now use AirPlay to stream content from their phone directly to a TV at select hotels. The feature is available at more than 60 IHG Hotels & Resorts locations across the United States, Canada, and Mexico, so give it a try the next time youre staying at a Holiday Inn or Candlewood Suites.The process is pretty painless: Upon turning your TV on, you should notice a QR code on the welcome screen. Simply scan it with a compatible Apple device to both connect to your room's wifi and authorize AirPlay to that screen.And thats itbecause the QR code is unique to your hotel room, you shouldnt find yourself accidentally streaming to other guests' sets, or vice versa. Apple says more locations will be added in the coming months, which makes sensethe limited rollout probably has something to do with the special LG TVs required for the setup, meaning it'll take time for other locations to stock the new displays.But what if youre not staying at an IHG property? This is where the hacks come in.Other ways to cast an iPhone to a hotel TVThere are plenty of dongles, like Roku and Fire TV sticks, that work with AirPlay right out of the box. The problem is getting a hotel TV to accept them.Hotel TVs tend to be a bit strict about which devices theyll let you plug in. Thats thanks to special control boxes that lock them down. Luckily, if you can physically get to your TVs hookups, you can (carefully) remove these boxes. Lifehacker has covered it before, but the gist is to look for an ethernet cable (or possibly an HDMI cable), gently remove it, and restart the TV before hooking up your accessories. Depending on your hotel, you might also want to disconnect the control box from power if youre able. Note that you do this at your own riskit's possible your hotel won't be happy with you unplugging its hardware.Once your device is plugged in, try swapping the TV input to your dongle and seeing if it works. If it does, simply connect it to wifi (you might need to open a browser page to do it, depending on your hotel) and youre good to go. If using the hotel's wifi isnt an option, dont worryAirPlay can work without it, and you can always fall back on a mobile hotspot.(Just be sure to hook your TVs control box up again before checking out!)

For instance, hotel chains like Wyndham and Hyatt already have Chromecasts connected to their TVs, letting you cast from your phone, or at least log into your streaming services, depending on how locked down they are. If youre lucky enough to have a Chromecast officially set up from the start, just follow your hotels instructions and you should be good to go. As time goes on, you might also see hotels with Google TV Streamers instead, as the Chromecast brand has technically been discontinued.Alternatively, your TV could have Google Cast built-in. Much like with Airplay, LG is now adding built-in Cast support to its hotel TVs, letting you sign-in via a QR code and requiring no extra hardware. LG says this will work on any hotel TV running webOS23 or later, which comes pre-installed on models released from 2023 on, and can also be applied to certain models from 2022. Theoretically, this should allow for wider availability than even LG's Airplay support, although it might take a while for the hotel industry's TV hardware to catch up.That's why you might also want to bring your own dongle, like a Fire TV Stick or Chromecast, with you. While its possible to stream content from an Android phone to a TV without a dongle, its probably not going to be easy in a hotel environment, since these workarounds usually require accessing specific smart TV apps or functions that you cant depend on your hotel to have or allow you to access.For the most seamless experience, I recommend a Chromecast (it'll be cheaper and smaller than a Google TV streamer, and will still work despite being discontinued), as certain other dongles can only mirror your screen, rather than cast content across devices. With casting, youll ensure you get the best resolution, and generally have a more intuitive experience. (Note, though, that Chromecasts do require wifi when they boot.)Once youre in your hotel room with your dongle, youll want to connect it to your TV following the same steps outlined in the iPhone section above: gently remove the hotel control boxs connection to the TV, restart the TV, plug your Chromecast in, and swap to the proper input to test that everything worked.If it did, try to connect your dongle to wifi (again, you may need to open a browser page). If the hotels wifi isnt working, you can either use a mobile hotspot to try casting, or you can screen mirror without using wifi at all, depending on your dongle (the Fire TV Stick is a good choice if this is a concern).
