Estimated reading time: 8–10 minutes · Difficulty: Beginner · Last updated: February 2026

⚡ Quick start (under 60 seconds)

Already know your way around? Here's the fast version. Scroll down for the full walkthrough.

Roku: Settings → Apple AirPlay and HomeKit → AirPlay On

iPhone: Control Center → Screen Mirroring → select your Roku

Open the Google Docs app → pick a doc → rotate to landscape

(Optional) Pair a Bluetooth keyboard for real typing speed

If you do only one upgrade: add a keyboard. It transforms the experience.

🎯 Why use Google Docs on a Roku TV?

Your iPhone is powerful, but 6 inches of screen isn't always enough. Here are the top reasons people set this up:

📐

Bigger screen

Reading and editing long documents on a phone is tiring. Casting to your 40–65" TV gives you a comfortable view—great for proofreading, studying, or reviewing contracts. Your iPhone stays the controller.

🏠

Lightweight "computer"

Don't want to boot a laptop? Traveling with just your phone? Pair your iPhone + Roku + Bluetooth keyboard and you have a basic workstation for outlines, meeting notes, scripts, and journal entries.

👨‍👩‍👧‍👦

Sharing & collaboration

Review a resume with family, walk a client through a plan, or do a group edit session—without passing a tiny phone around. Everyone sees the same thing on the TV while you control it on iPhone.

🎤

Presenting & teaching

For informal presentations—a class, a book club, a team standup—you can display a doc on the TV while scrolling and highlighting key sections on your iPhone. No projector needed.

📖

Comfortable reading

Long-form reading on a phone causes eye strain. Mirror a doc to your TV and read from the couch with the text at a comfortable size. Combine with voice dictation for hands-free note-taking.

♿

Accessibility

For anyone with vision challenges, projecting text onto a large TV makes documents far more readable. Combine with iPhone's accessibility features (zoom, bold text, larger type) for the best experience.

⚠️ Heads up: Roku is a streaming platform, not a full computer. You're using the TV as a display while your iPhone does the work. For reading, editing, and light collaboration, that's perfectly fine. For heavy spreadsheet work or multi-window tasks, a laptop is better.

🧰 What you need (checklist)

Gather these before you start. Most people already have everything.

✅ Required

📱

iPhone

Any model running iOS 14.5 or later (for AirPlay to Roku). Older iPhones work with the HDMI adapter method.

📺

Roku device or Roku TV with AirPlay 2 support

Most Roku TVs from 2019+ and streaming sticks from Roku Ultra (2019+) support AirPlay 2. 📡 Check your model here.

📶

Same Wi-Fi network

Both your iPhone and Roku must be on the exact same Wi-Fi network. Guest networks, VPNs, and separate 2.4 GHz / 5 GHz SSIDs can block discovery.

📄

Google Docs app (or Safari)

Download the free 📱 Google Docs iOS app from the App Store. You can also use Safari at docs.google.com, but the app gives a better mobile experience.

🌟 Strongly recommended (makes it 10× nicer)

⌨️

Bluetooth keyboard

The single biggest upgrade. Typing on a phone keyboard while watching a TV is awkward. A Bluetooth keyboard makes it feel like a real workstation. Budget picks start at ~$20.

🖱️

Bluetooth mouse or trackpad

Not required, but helpful for precise cursor placement when editing. iPhone supports Bluetooth mice since iOS 13.

🔋

Phone stand + charger

Screen mirroring + the Docs app will drain your battery faster than normal. Keep it plugged in for long sessions.

🔉

Do Not Disturb / Focus mode

Mirroring shows ALL notifications on the TV. Enable Focus mode before you start to avoid embarrassing pop-ups in front of others.

📺 Method 1 (Best): AirPlay screen mirroring

AirPlay is built into both your iPhone and supported Roku devices. No extra apps, no extra hardware—just your Wi-Fi.

A Enable AirPlay on your Roku

You only need to do this once. It stays on until you turn it off.

Grab your Roku remote and press the Home button.

Scroll down to Settings and press OK.

Select Apple AirPlay and HomeKit. If you don't see this option, your Roku model may not support AirPlay—check the supported models list.

Set AirPlay to On.

(Recommended) Set Require Code to First Time Only — this prevents random neighbors from projecting to your TV.

B Start Screen Mirroring on your iPhone

Open Control Center on your iPhone:

Face ID iPhones

Swipe down from the top-right corner

Touch ID / Home button

Swipe up from the bottom edge

Tap the Screen Mirroring icon (two overlapping rectangles).

Wait a moment for your Roku to appear in the list, then tap its name.

If prompted, enter the 4-digit code shown on your TV screen into your iPhone.

Your iPhone screen should now appear on the TV. You'll see everything—home screen, apps, notifications.

💡 Pro tip: Start mirroring before opening Google Docs. This avoids the "where did my screen go?" confusion that catches beginners off guard.

C Open and use Google Docs

Open the 📄 Google Docs app on your iPhone (or go to docs.google.com in Safari).

Pick an existing doc or tap + to create a new one.

Rotate your iPhone to landscape for a wider view on the TV. This fills more of the TV screen and makes text easier to read.

Use pinch-to-zoom on your iPhone to increase text size until it's comfortable to read from your couch distance (usually 6–10 feet).

Start typing, editing, or reading. Everything you do on the iPhone shows up on the TV in real time.

⌨️ Keyboard shortcut: If you paired a Bluetooth keyboard, press ⌘ + F to search within a document—great for jumping to specific sections during a presentation.

🛑 How to stop mirroring

Open Control Center again → tap Screen Mirroring → tap Stop Mirroring. Your Roku will return to its normal home screen.

⌨️ Workflow tips (make it feel like a real computer)

Once mirroring works, these tips take it from "cool trick" to "actually useful workstation."

1. Add a Bluetooth keyboard (biggest upgrade)

Put your Bluetooth keyboard in pairing mode (usually hold a button until a light blinks).

On iPhone: Settings → Bluetooth → On → tap your keyboard name when it appears.

Open Google Docs and start typing. Your iPhone is now a mini workstation, and the TV shows everything big and clear.

💰 Budget pick: The Logitech K380 (~$30) or Apple Magic Keyboard work great. Any Bluetooth keyboard will do—even a $15 Amazon basic one. See top picks here.

2. Optimize readability on the TV

Use landscape orientation—it fills the TV better than portrait mode.
Pinch-to-zoom until you can read comfortably from your couch (test by looking at the TV, not your phone).
Increase iPhone text size: Settings → Display & Brightness → Text Size or use 🔎 Accessibility zoom.
Structure your docs with headings (H1, H2, H3). Google Docs builds an automatic outline you can jump to.
Use dark mode in the Docs app for easier TV viewing in dimly lit rooms.

3. Present or review with others

Use ⌘ + F (keyboard) or the search icon (in-app) to jump to specific sections during a walkthrough.
Switch to Suggesting mode (tap the pencil icon → choose "Suggesting") for group review sessions. Changes appear as colored suggestions without altering the original text.
Zoom extra when reading aloud—TV viewing distance (6–10 ft) is much longer than phone distance.
Use the Comments feature to leave notes inline instead of interrupting the speaker.

4. Use voice dictation for drafting

Don't have a keyboard? Use iPhone's built-in dictation:

Tap in Google Docs → tap the microphone icon on the on-screen keyboard.
Speak naturally. The text appears on both iPhone and TV.
Say "period," "comma," "new paragraph" for punctuation.
Draft by voice, then edit with a keyboard for a fast, low-fatigue workflow. 🎤 Learn more.

🧩 Alternatives (if AirPlay isn't available or is flaky)

AirPlay not working? Older Roku model? Here are reliable backup methods.

🔌

Option 2: USB-C to HDMI adapter (iPhone 15 and newer)

If you have an iPhone 15, 15 Pro, 16, or 16 Pro, your phone uses USB-C. A USB-C to HDMI adapter plugs directly into your TV's HDMI port.

✅ Pros

Zero lag (wired connection)
No Wi-Fi dependency
Works on any TV with HDMI
Most reliable method

❌ Cons

Costs $15–$50 for the adapter
Tethered by a cable
TV input must switch from Roku

⚡

Option 3: Lightning to HDMI adapter (iPhone 14 and older)

For iPhones with a Lightning port, Apple's Lightning Digital AV Adapter (~$49) mirrors your screen to any HDMI TV.

✅ Pros

Minimal lag, rock-solid stable
Official Apple product
Has a charger pass-through port

❌ Cons

$49 from Apple (cheaper clones exist)
Tethered by cable
Max output is 1080p

🔄

Option 4: Alternative "TV computer" setups

Apple TV + AirPlay: If you're in an Apple household, an Apple TV gives you the most seamless AirPlay experience—no Roku configuration needed.
Chromecast + Google Home: If you have an Android tablet or Chromebook alongside your iPhone, casting from Chrome is another option.
Cheap laptop or tablet: If you do this daily, a $150–$300 Chromebook or iPad connected to your TV is a better long-term solution than phone mirroring.
Google Slides instead of Docs: If your main goal is presenting (not editing), Google Slides gives you a proper full-screen presentation mode. Learn more.

🛠️ Troubleshooting (fix it fast)

Most issues fall into these common categories. Try solutions in order—they're ranked from most-likely to least-likely fix.

❌ "My Roku doesn't show up in Screen Mirroring"

Check AirPlay is on: Roku → Settings → Apple AirPlay and HomeKit → AirPlay: On
Same Wi-Fi: Confirm iPhone and Roku are on the exact same network (not guest, not VPN, not a differently named 2.4 GHz vs 5 GHz band).
Restart both devices: Power-cycle the Roku (unplug for 10 seconds) and restart your iPhone. This fixes most discovery issues.
Update Roku software: Settings → System → System update → Check now. 🔄 Update guide.
Update iPhone: Settings → General → Software Update.
Check router settings: Some routers have "Client Isolation" or "AP Isolation" enabled, which blocks devices from seeing each other. Disable it in router admin.

🌀 "It connects but lags, stutters, or looks blurry"

Use 5 GHz Wi-Fi: The 5 GHz band has more bandwidth and less interference than 2.4 GHz. Connect both devices to your 5 GHz network if available.
Move closer to the router or use a Wi-Fi extender. Walls and distance degrade the signal.
Reduce network congestion: Pause other streaming (Netflix, YouTube), large downloads, and gaming on the same network.
Close background apps on your iPhone— especially anything using data (social media, cloud syncing).
Lower zoom slightly: Extreme zoom can look soft on some TVs due to iOS upscaling.
Restart your router: If all else fails, reboot the router itself.

😤 "Typing on the phone keyboard is annoying"

Best fix: Add a Bluetooth keyboard ($15–$100). This is the single biggest quality-of-life improvement.
Second best: Use voice dictation (tap the microphone icon on the keyboard) to draft text, then edit manually.
Third: Use iPhone's swipe keyboard (slide your finger across letters instead of tapping each one).
Keep the iPhone charging during long sessions.

🔇 "Mirroring disconnects randomly"

Disable Auto-Lock: Settings → Display & Brightness → Auto-Lock → Never (remember to turn it back on later).
Keep the Docs app in the foreground. Switching to another app may pause mirroring on some Roku models.
Check for Roku screensaver: The Roku screensaver can kick in and interrupt mirroring. Extend the screensaver timer in Roku Settings.
Wi-Fi range: If you walk too far from the router with your phone, the connection drops.

❓ Frequently asked questions

Quick answers to the most common questions.

Q: Can I edit Google Docs while mirroring, or only read?

You can do both! Full editing works—typing, formatting, inserting images, commenting, and collaborating with others in real time. The TV mirrors exactly what your iPhone shows.

Q: Does my Roku support AirPlay? How do I check?

Go to Settings → Apple AirPlay and HomeKit on your Roku. If you see this menu, your Roku supports AirPlay. If you don't see it, your model is too old or needs a software update.

Q: Will this work with Google Sheets and Google Slides too?

Yes! Screen mirroring shows everything on your iPhone, including Google Sheets, Google Slides, email, web browsers, and any other app. Google Slides even has a built-in presentation mode.

Q: Is there any delay between my phone and the TV?

Over AirPlay, there's typically a 0.1–0.5 second delay. You'll notice it slightly when typing, but it's not a problem for most tasks. Using an HDMI cable eliminates the delay completely.

Q: Can other people in my house see what I'm mirroring?

Only on the TV connected to your Roku. Set "Require Code" to "Every Time" in Roku AirPlay settings to prevent others from accidentally mirroring to your TV.

Q: Does mirroring use a lot of battery?

Yes, more than normal use. Expect about 20–30% per hour of mirroring with active use. Keep your iPhone plugged into a charger for sessions longer than 30 minutes.

Q: Can I use Google Docs directly on Roku without an iPhone?

No. Roku doesn't have a web browser or Google Docs app. You need a phone, tablet, or computer to create the content—Roku just displays it via screen mirroring.

Q: What about iPad instead of iPhone?

An iPad works even better! Larger screen means better mirroring quality, and iPadOS supports mouse, keyboard, and Split View for multitasking while mirroring.

🔒 Privacy & safety tips

Screen mirroring shows everything on your phone—including notifications, messages, and banking apps. Protect yourself:

🔐

Require an AirPlay code

Set Roku AirPlay to "Require Code: Every Time" if you live in an apartment or shared building. This prevents neighbors from accidentally connecting.

🌙

Enable Focus / Do Not Disturb mode

Before mirroring, turn on Focus mode to block notification banners from appearing on the TV. This avoids embarrassing messages popping up during a presentation.

📶

Avoid public / shared Wi-Fi

Don't mirror sensitive documents on hotel, café, or shared office networks. Other devices on the same network could potentially intercept AirPlay traffic.

🔔

Review notification settings

Go to Settings → Notifications and hide previews for sensitive apps (Messages, Email, Banking) so they don't show content on the TV.

⏹️

Always stop mirroring when done

Don't just close the doc—actively stop Screen Mirroring from Control Center. Otherwise your phone stays connected and continues showing everything.

👀

Be aware of your environment

If you're working on confidential documents, make sure only trusted people can see the TV. Close blinds if the TV faces a window.
