How to set up a wedding slideshow on Apple TV

I have set up wedding slideshows on every major TV streaming device — Apple TV, Chromecast, Roku, Fire TV — and the universal HDMI cable. Each one has its own quirks, and the day-of-wedding stress is not the moment to be figuring them out from scratch. This post walks through the exact steps for each device, in the order I would actually run on a wedding day, with the gotchas I have hit so you do not have to.

These instructions assume your slideshow is a web app that plays in a modern browser — Memories Online, Wedibox, Wedding.studio, Guestpix, or any of the apps in the best wedding slideshow apps for 2026 list. The browser-based playback is the common case across that whole category. If your slideshow is a pre-rendered MP4, you can skip most of this post and just use the venue's media player or USB stick.

The five paths below are listed in roughly the order I would try them at a typical wedding venue: Apple TV first because it is the highest-quality experience when available, HDMI last because it always works.

Apple TV (most polished)

Apple TV is the best wedding-slideshow experience when the venue has one. AirPlay from a laptop or iPhone gives you a full-quality mirror with no perceptible lag, the slideshow looks crisp on a 4K TV, and the remote is easy to hand to a venue tech if needed.

1. Make sure the Apple TV and your laptop or phone are on the same WiFi network. The venue WiFi works; a phone hotspot is fine if the venue WiFi is unreliable.
2. On the Apple TV, navigate to AirPlay & HomeKit settings and confirm AirPlay is enabled. (It is on by default but venue Apple TVs sometimes get locked down.)
3. On your laptop (macOS), open the slideshow URL in Safari or Chrome. Click the Control Center icon in the menu bar. Click Screen Mirroring. Choose the Apple TV.
4. The Apple TV screen now mirrors your laptop. Open the slideshow tab in fullscreen mode (Cmd-Shift-F or the slideshow's own fullscreen button). The Apple TV will display the slideshow at the laptop's resolution.
5. On an iPhone instead: open the slideshow URL in Safari. Open Control Center. Tap Screen Mirroring. Choose the Apple TV. Rotate the phone landscape and tap fullscreen.

Gotcha: Some venues lock down their Apple TV to a specific guest network. If AirPlay does not show the Apple TV in the device list, ask the venue tech crew about the AirPlay code — older Apple TVs require a one-time PIN from the TV screen the first time a new device connects.

Gotcha: Laptop battery dies during a four-hour reception. Plug the laptop in. The slideshow runs at full screen brightness which drains battery faster than typical use.

Chromecast (good, second-most-common)

Chromecast is the second-most-common venue device, especially in mid-range hotels and event spaces. The cast experience is slightly less seamless than AirPlay but works reliably with Chrome.

1. Confirm the Chromecast is plugged in, the TV is on the correct HDMI input, and the Chromecast and your laptop are on the same WiFi network.
2. On your laptop, open the slideshow URL in Chrome.
3. Click the three-dot menu in Chrome's top-right corner. Choose Cast.
4. In the cast dropdown, click "Sources" and pick "Cast tab" (default) or "Cast desktop" (better for keeping the slideshow visible while you do other things on the laptop).
5. Pick the Chromecast device. The Chrome tab now mirrors to the TV. Make the Chrome tab fullscreen on your laptop and the TV will fullscreen too.

Gotcha: Cast tab mode can lose the connection if the laptop sleeps. Disable laptop sleep on power-connected mode in System Preferences before the wedding.

Gotcha: Older Chromecasts (first generation) sometimes struggle with high-resolution slideshow images. If the cast looks pixelated, reduce the slideshow's image-quality setting in the slideshow app's settings.

Roku (less common but improving)

Roku devices are increasingly common in venues that have replaced their older Apple TVs. Roku does not have native AirPlay or Cast on all models — newer Roku models support AirPlay but older ones require the Roku app.

1. Check the Roku model. Models from the past two or three years support AirPlay; older models need the Screen Mirroring path through the Roku mobile app.
2. Newer Roku (with AirPlay): Same flow as Apple TV section above. Open the slideshow in Safari or Chrome on macOS, click Screen Mirroring, choose the Roku.
3. Older Roku (no AirPlay): Install the Roku mobile app on your phone. Sign in with the Roku account. Open the slideshow URL in the phone's browser. Use the Roku app's Screen Mirroring feature to mirror the phone to the Roku.
4. Universal fallback for any Roku: Use the Roku Web Browser channel (free; install from the Roku channel store) and navigate to the slideshow URL directly. The Roku browser is slow but works.

Gotcha: Screen mirroring from an iPhone to a non-AirPlay Roku is only stable when both are on the same 5GHz WiFi band. Older venue WiFi networks default to 2.4GHz which produces stutter.

Fire TV (Amazon devices)

Fire TV sticks are common in budget-friendly venues and BYO-device receptions. The cast experience is similar to Chromecast.

1. From a laptop running Chrome: same Cast flow as the Chromecast section. Fire TV shows up as a cast destination if the Fire TV has the Google Cast Receiver app installed (free; install from the Fire TV app store ahead of time).
2. From an iPhone: install the AirPlay receiver app on the Fire TV (search "AirScreen" or similar in the Fire TV app store). Then mirror from the iPhone using the same Control Center → Screen Mirroring flow as the Apple TV section.
3. Universal fallback: Fire TV ships a Silk browser. Navigate to the slideshow URL directly in Silk. Slow but functional.

Gotcha: Fire TV remotes are easy to lose at receptions. Pair the Fire TV remote with the venue tech crew before the ceremony so they can help if it goes missing.

HDMI cable (the universal fallback)

If none of the streaming-device paths work, an HDMI cable from a laptop directly to the venue projector or TV always works. This is my go-to setup for outdoor weddings, tent receptions, and any venue where the WiFi is suspect.

1. Bring a 25-foot HDMI cable to the wedding. Yes, 25 feet — the receiver TV is usually further from your laptop position than you expect, especially in tented receptions where the projector is at the back of the tent and the laptop wants to live near the DJ booth.
2. Bring at least two USB-C-to-HDMI adapters (one as backup) if your laptop is a recent MacBook or Surface. Older laptops with built-in HDMI ports skip this step.
3. Plug the HDMI into the laptop. Plug the other end into the projector or TV. Switch the TV to the corresponding HDMI input.
4. On the laptop: open the slideshow URL in Chrome or Safari. Use System Preferences → Displays to set the external display as Mirror or Extended (Mirror is simpler for a fixed slideshow). Drag the slideshow window to the external display if Extended. Make it fullscreen.
5. Close all other windows on the laptop's main display so a notification or alert never shows up on the venue screen mid-reception.

Gotcha: Disable laptop notifications via Do Not Disturb mode before plugging in. A Slack or iMessage notification appearing on the wedding-reception screen mid-toast is the kind of memorable mistake nobody wants.

Gotcha: Some venue projectors only accept 1080p or lower. If the slideshow looks stretched or cropped, set the laptop display resolution to 1920×1080 manually in System Preferences.

Universal preparation steps (do these regardless of device)

A few things help every setup. Do them the day before, not the day of.

1. Do a dress rehearsal at home. Use the same laptop, same browser, same slideshow URL, same streaming device (or a similar one). Confirm fullscreen mode works. Confirm the slideshow auto-advances. Confirm the audio plays at the volume you want.
2. Bring extras. A backup laptop charger, a backup HDMI adapter, a backup HDMI cable, a backup phone charger. The wedding day is not the moment to discover that a single cable failure breaks the slideshow.
3. Designate one person. Pick a member of the wedding party who is comfortable with technology and hand them the laptop responsibility. They will need to plug it in, log in, navigate to the slideshow, and put it in fullscreen mode at the right moment. Brief them once during the rehearsal dinner.
4. Confirm the venue WiFi. Get the WiFi name and password from the venue manager when you book. Test the WiFi from the corner where the laptop will live during the reception. If the venue WiFi is unreliable, plan to use a phone hotspot as backup.
5. Set the slideshow to auto-advance. Most apps default to manual advance during preview but you want auto-advance during the reception. Confirm the setting before the wedding day.

The Memories Online Help page has device-by-device technical setup guides as well.

What I would do differently if I had to start over

The single biggest lesson from setting up wedding slideshows is that the technology fails about 5% of the time, and on a wedding day a 5% failure rate is too high. The HDMI cable is the only path that has zero failure cases — every laptop, every projector, every venue. AirPlay and Cast both have edge cases (locked-down venue Apple TVs, 2.4GHz-only Chromecasts) where they will not work and you cannot fix them in the moment.

So my real advice: pick the streaming-device path you would prefer, but bring the HDMI cable and adapter as backup. The cable lives in the laptop bag from the rehearsal dinner through the end of the reception. If the streaming device fails, you switch to HDMI in two minutes and the slideshow is back. Without the cable, a streaming-device failure means your slideshow is dark for the rest of the wedding.
