There are four realistic ways to put video on a Tesla screen: Tesla Theater (the built-in apps, which run only while parked), mirroring your phone's display (much harder than it sounds, with no guarantees), a USB stick (which in a Tesla plays music, not films), and a player that runs inside the car's browser — the category Roadly belongs to. None of the four wins outright. They differ in setup time, in whether passengers can still see video while the car is moving, and in whether you watch your own material or someone's catalogue. This page lays out what each one does, where each one breaks, and who should pick what — including the many people for whom Roadly is the wrong answer.
1Tesla Theater: what it does and where it stops
Tesla Theater is the best way to watch video in a Tesla while the car is parked, and for a lot of owners the conversation ends right there. The apps are built into the car, the picture runs at full quality, sound goes through the car's own system, and there is nothing to configure beyond signing in.
It has exactly one limit, and it is a hard one: Theater opens only when the car is in Park, and video stops the moment you drive off. That is a deliberate Tesla decision, not a fault. You also need a data connection — Premium Connectivity is what keeps streaming alive once the car is away from home Wi-Fi.
If your actual use case is "I'm plugged in at a charger for forty minutes and want something to watch," Theater already covers it completely. There is no reason to add anything, and anyone telling you otherwise is selling something.
2Phone mirroring: why it's harder than people expect
Mirroring a phone to a Tesla screen isn't a feature you switch on — it's a technical problem you solve again every time, and usually it isn't worth the trouble. Worth explaining why, because it's the first idea almost everyone has.
A Tesla has no CarPlay, no Android Auto, no video input, and it doesn't speak the casting protocols your phone knows, such as AirPlay or Chromecast. The only workable route sends the phone's picture over the network into a web page that the car's browser opens: the phone compresses its screen, ships it to a server, the browser receives it and paints it. That does work, but the phone has to stay awake and connected, it burns battery and data, and every hop adds lag.
Then there's an obstacle the network can't fix. Streaming apps on your phone protect what they play, and many of them go black the moment the screen is being captured. No amount of clever configuration changes that. Mirroring makes sense for material you control — a presentation, footage you shot yourself, an app with nothing to protect — not as a substitute for a streaming service.
3The USB stick, and why it doesn't solve video
The car does read the port, but its player is built for music: video files are not played back. For downloaded films the route is a tablet in a passenger's hands, not the car's screen.
The port does two real jobs: music, including lossless formats, and storing dashcam and Sentry recordings. Both are useful; neither is a film to watch.
It's worth spelling out, because the USB stick is the advice that circulates most in forums, almost always from people who never tried it with video: you prepare it, you plug it in, and what appears in the menu is music. If what you want is offline films in the car, the honest answer is a tablet loaded before you leave.
4A player in the car's browser, such as Roadly
The fourth route is to open a web address in the browser the Tesla already ships with and let a page handle the video — that's the category Roadly sits in, and it means installing nothing and changing nothing about the car. The browser is the shared ground here: every service of this kind runs through it.
The part that matters is how the picture gets drawn. An ordinary video element on a page is blanked by the car once the vehicle is moving. Roadly instead decodes the stream and paints the frames one by one onto a graphics canvas. A canvas is not the video element the car blanks, so it keeps being drawn and passengers can keep watching while the car is moving. YouTube, Twitch, an IPTV subscription you already pay for, Plex, Google Drive, Spotify and radio all run through that path.
This route carries two real costs. First, video is capped at 720p on purpose: painting frames by hand is heavier work than letting the car do it, and above that cap the picture starts to stutter. Second, it lives entirely on the car's connection, so weak coverage degrades it immediately — something a USB stick never suffers from. Access is a 7, 14 or 30-day pass, paid manually, with nothing renewing on its own.
And the rule that outranks everything still holds: video is for passengers, or for a car that's parked. Whoever is driving has a road to look at.
5The comparison, in one table
Side by side, the four routes separate on three things: how long it takes to start, whether passengers see anything while moving, and whether you watch your own material or a catalogue.
| Approach | Setup | While moving (passengers) | What you watch |
|---|---|---|---|
| Tesla Theater | None, just sign in | No, parked only | The built-in app catalogues |
| Phone mirroring | Long, and repeated | Unreliable, no guarantees | Whatever is on the phone |
| USB stick | Copy the files | Audio only | Your music, not video |
| Browser player | Open a web address | Yes, painted to canvas | Your services and files |
One cell deserves a footnote. "Unreliable, no guarantees" for mirroring isn't lawyerly hedging — it depends on your phone, your network and the app you're mirroring, and it can stop working without you having changed a thing.
6Where Roadly is worse than the alternatives
Roadly loses on three concrete points, and knowing which ones helps you choose properly. The first is picture quality: 720p is a deliberate ceiling, and on a screen that size the gap against Tesla Theater is visible. If you're watching a film parked at a charger, Theater gives you a better image, for nothing.
The second is the dependency on coverage. Roadly has no offline mode — everything comes down the car's connection, and in a thin-signal area the picture stalls. A file already downloaded to a tablet plays in that same spot regardless.
The third is guarantees. Roadly does not promise that any given channel, app or third-party service works today or will work tomorrow: those services change on their own schedule, and sometimes they break. Tesla Theater's apps are maintained by Tesla together with the companies that publish them, and that's a kind of durability an independent player simply cannot match.
7Who each option is genuinely for
Each route has someone it's clearly best for, and recognising yourself in one of these lines is worth more than any spec comparison.
- You only ever watch parked, at home or at a charger: Tesla Theater, full stop. Paying for anything extra buys you nothing.
- You want to show passengers something of your own — footage you shot, a presentation: mirroring can do it, as long as you accept how fragile it is.
- You take long trips through dead zones, or you have kids with a fixed set of films: a tablet loaded before you leave — none of these four routes puts offline films on the car's screen.
- Your passengers want to watch while the car is moving, and you already pay for the services: a browser player is the only category that addresses that case at all.
- You almost always drive alone: none of these options is for you. That rule has no exceptions.
8How to choose, in three questions
The decision comes down to three questions in order, and the first "yes" settles it.
One: do you only ever watch while parked? If yes, use Tesla Theater and stop reading — it's built in, it's full quality, it adds no cost. Two: do you often drive where coverage is poor, or is the thing you want to watch a file you already have? If yes, the answer is a tablet loaded before you leave: none of these four routes puts offline films on the car's screen.
Three: do you have passengers who want to watch while the car is moving, on services you already pay for? Only at that point does a browser player become the right answer, and it's worth trying a short pass before committing to a longer one — that way your passengers see how it behaves on the roads you actually drive, which is the only test that counts.

9Frequently asked questions
Can I watch video while driving?
No. None of the options on this page is meant for the person driving. Video is for passengers, or for a parked car. Watching the screen at the wheel is dangerous and illegal.
Does Roadly modify the car in any way?
No. It's a web page you open in the browser the Tesla already has. Nothing is installed, the car's software isn't touched, and no work on the vehicle is required.
Why is video capped at 720p?
Because frames are painted one at a time onto a canvas, and that work loads the car's processor. At 720p the picture stays smooth; push the resolution higher and it starts to stutter. The cap is a stability choice.
Do I need Tesla Premium Connectivity?
Anything that comes over the network — Tesla Theater away from home Wi-Fi, or a browser player — needs a working data connection, and Premium Connectivity is the normal way to have one. Only files already downloaded to your own device work without it.
Can I watch Netflix or Disney+ through a browser player?
No, and nobody should promise you otherwise. Services with content protection won't play outside their own apps: in the car's browser they stay black. For those catalogues, Tesla Theater is the route, with the car parked.
Will phone mirroring work with my car?
There's no guarantee. It depends on your phone, your network and the app you're mirroring, and many streaming apps black out the picture when the screen is being captured. It's only sensible for content of your own.
