A large TV is often the best screen in the room: in a meeting room without a projector, in a shop window, at a family party or in a reception area where a deck should loop all day. Getting the slides onto it is less obvious than it should be, because a TV is not a computer. Most models do not run PowerPoint, and the ones that open documents from a USB stick rarely show them properly.
So the question is not “how do I open my .pptx on the TV” but “in which form does the TV accept my slides”. There are four answers: as a signal through a cable, as a video file, as pictures, or as a screen sent over Wi-Fi. This guide goes through all four, then through the mistakes that make slides look cut off or blurry, and ends with the way that needs no file at all.
| Situation | Best way | Keeps animations | Needs a computer at the TV |
|---|---|---|---|
| Meeting, you present live | HDMI cable | Yes | Yes |
| Loop in a reception or shop window | Video on a USB stick | Yes, baked in | No |
| Photos or a simple slideshow at home | Pictures (JPEG) on a USB stick | No | No |
| Meeting room with a Chromecast or Google TV | Cast a Chrome tab or the screen | Yes | Yes, but no cable |
| Mac and an Apple TV or AirPlay TV | AirPlay screen mirroring | Yes | Yes, but no cable |
| Windows laptop and a Miracast TV | Win+K wireless display | Yes | Yes, but no cable |
With a cable: HDMI from your laptop
A cable is still the most reliable way: no network, no delay, sound included, and PowerPoint’s Presenter View keeps your notes on the laptop while the TV shows only the slide. Most Windows laptops have an HDMI port; recent MacBook Pro models have one too, while a MacBook Air needs a USB-C to HDMI adapter.

Press Win+P. Duplicate shows the same picture on both screens; Extend makes the TV a second screen, which PowerPoint needs for Presenter View.

Connect and pick the input
Connect the TV (with an adapter where the Mac has no HDMI port) and choose that HDMI input on the TV.
Mirror or extend
Open System Settings → Displays, select the TV and set Use as to Mirror for Built-in Display, or leave it as an extended display for Presenter View. Cmd+F1 switches mirroring on and off on most Macs.
System Settings → Displays: Use as Mirror Start the show
In PowerPoint for Mac choose Slide Show → Play from Start (Cmd+Shift+Return) or Presenter View. PowerPoint puts the slides on the extended screen and your notes on the Mac.
Without a computer: a video on a USB stick
For a deck that should run by itself — in a reception, at a trade fair, on a party TV — export it as a video. A video plays on almost every smart TV, keeps transitions and animations, and can loop. The steps below are for PowerPoint for Microsoft 365; PowerPoint 2019 and 2021 have the same commands.
Export a PowerPoint as a videoWindows
Open the export
Choose File → Export → Create a Video.
File → Export → Create a Video Choose the quality
Pick Full HD (1080p) for most TVs, Ultra HD (4K) only for a 4K TV and a deck with large photos — the file gets much bigger.
Set how long each slide stays
Choose Don’t Use Recorded Timings and Narrations and set Seconds spent on each slide (5 seconds by default). Text-heavy slides need 10 to 15 seconds to be read from across a room.
Create a Video: quality and seconds per slide Create the file
Click Create Video, choose MPEG-4 Video (*.mp4) as the file type and save. A long deck can take several minutes; the progress shows in the status bar at the bottom.
Export a PowerPoint as a videoMac
Open the export
Choose File → Export. In the dialog set File Format to MP4.
PowerPoint for Mac: File → Export, File Format MP4 Quality and timing
Choose a quality, and set the seconds each slide is shown unless you recorded timings. Click Export.
Play the video from the stickTV
Prepare the stick
Use a stick formatted as exFAT or FAT32; FAT32 cannot hold a file larger than 4 GB, and some older TVs read only FAT32. Copy the .mp4 to the top level of the stick.
Open it on the TV
Plug the stick into the TV’s USB port. Most TVs offer to open it at once; otherwise choose Source → USB and open the video. For a loop, look for Repeat in the player’s options.

The simplest way: pictures on a USB stick
Every TV that plays photos from USB can show your slides as pictures. You lose animations, but you gain control: the remote moves forward and back, like a clicker.
Save every slide as a pictureWindows and Mac
Export as JPEG or PNG
Windows: File → Export → Change File Type → JPEG File Interchange Format, then Save As and choose All Slides. Mac: File → Export, File Format: JPEG, and Save Every Slide.
Export → Change File Type → JPEG Copy the folder to the stick
PowerPoint saves a folder with Slide1.jpg, Slide2.jpg and so on. Copy the whole folder to the stick and open it in the TV’s photo viewer; most viewers sort by name, so the order stays right.
Without a cable: Chromecast, AirPlay and Miracast
Chromecast and Google TV
Chromecast receives what Google Chrome sends. Open the deck in PowerPoint for the web in Chrome, then open Chrome’s menu (the three dots) and choose Cast, save, and share → Cast… (older versions: Cast…). Under Sources choose Cast tab for the browser tab, or Cast screen to send the whole desktop, which also works for the PowerPoint app. Start the slide show and the TV follows. Expect a delay of up to a second — fine for slides, not for video in the deck.
AirPlay on a Mac, iPhone or iPad
On a Mac open Control Center → Screen Mirroring and choose the Apple TV or an AirPlay-compatible TV (many recent Samsung, LG, Sony and Vizio models). On an iPhone or iPad open the deck in the PowerPoint app, swipe down for Control Center, tap Screen Mirroring and pick the TV, then start the slide show in the app.
Miracast on Windows
Many TVs and Fire TV devices accept Miracast (often called Screen Mirroring in the TV’s menu). Switch it on on the TV, press Win+K on the laptop, choose the TV, and the screen appears. Use Extend in Win+P afterwards if you want Presenter View.
| Action | Windows | Mac |
|---|---|---|
| Choose Duplicate or Extend | Win+P | Cmd+F1 (mirroring on/off) |
| Connect to a wireless display | Win+K | Control Center → Screen Mirroring |
| Start the slide show from the beginning | F5 | Cmd+Shift+Return |
| Start from the current slide | Shift+F5 | Cmd+Return |
| Black screen during the show | B | B |
| End the show | Esc | Esc |
Why slides look wrong on a TV, and the fixes
- Black bars left and right. The deck is 4:3. TVs are 16:9: change it under Design → Slide Size → Widescreen (16:9) before exporting, and check every slide afterwards.
- Edges cut off. Overscan: set the TV’s picture size to Just Scan or Screen Fit, as in the tip above.
- Small text. A TV is watched from three metres or more. Keep body text at 24 pt and above, and no more than a handful of lines per slide.
- Washed-out colours. TVs often run a vivid picture mode. Switch to Movie, Cinema or Filmmaker mode for colours closer to your laptop.
- The video stops after one run. Turn on Repeat in the TV’s player, or export with more slides and repeat the deck inside the video.
- Fonts swapped in the TV’s viewer. The TV does not have your fonts. Export a video or pictures instead of handing it the .pptx.
- A 4K video that stutters. The TV or the stick cannot keep up. Export in Full HD (1080p).
Designs for this kind of deck
Every design brings its own colours, fonts and layouts to the whole deck.
The way without any file: present from a web link
Every presentation made in ExpertSlides can be published as a read-only web link from the editor’s top bar (Web link). The link opens the slides in any browser — including the browser of a smart TV, a Chromecast tab or a laptop at the TV — with Present and Presenter view. Nothing is copied to a stick, nothing is installed, and if you fix a typo and publish again, the same link shows the new version. Stop sharing takes the link down.
In the editor itself, Present shows the deck full screen (F5, or Cmd+Enter on a Mac and Ctrl+Enter on Windows), and Presenter view opens a separate audience window you can drag onto the TV while your notes and the next slide stay on the laptop. Slides are 16:9, so they fill a TV without bars.
For a reception loop, a calm design with large type works best — look through Design Templates, or let the AI presentation maker draft the whole deck from a sentence. If you are converting older material first, the guide on converting to and from PowerPoint covers pictures, Canva and Illustrator.
Questions, answered
Can I play a PowerPoint on a TV from a USB stick?
Usually not as a .pptx file: most TVs cannot open PowerPoint. Export the deck as an MP4 video or as JPEG pictures, copy them to a USB stick formatted as exFAT or FAT32, and open them in the TV’s media player.
How do I loop a PowerPoint on a TV?
Export it as a video with a fixed number of seconds per slide, copy the MP4 to a USB stick and switch on Repeat in the TV’s player. On a computer connected to the TV, use Slide Show, Set Up Slide Show and Loop continuously until Esc.
How do I cast PowerPoint to a Chromecast?
Open the deck in PowerPoint for the web in Google Chrome, choose Cast from Chrome’s menu, select the Chromecast and cast the tab, then start the slide show. Cast screen sends the whole desktop, which also works for the PowerPoint app.
Why are my slides cut off at the edges of the TV?
The TV enlarges the picture slightly (overscan). Set the picture size in the TV’s settings to Just Scan, Screen Fit or Fit to Screen, depending on the brand.
Can I use Presenter View with a TV?
Yes, when the TV is an extended display rather than a mirror. On Windows press Win+P and choose Extend; on a Mac do not mirror the display. PowerPoint then shows the slides on the TV and your notes on the laptop.
Can I show an ExpertSlides presentation on a smart TV?
Yes. Publish a web link from the editor and open it in the TV’s browser, or cast the browser tab. The link has Present and Presenter view, and nothing has to be copied to a stick.
