How to Connect Your Phone to a TV in Sri Lanka (2026 Guide)

There are three ways to get what’s on your phone onto a television, and only one of them works with every phone. Picking the wrong one is the most common wasted purchase in this whole category — so here is the honest version, including the part most sellers leave out.

The short answer

Your phone	What works	What it costs
iPhone 15 or newer (USB-C)	USB-C to HDMI cable or adapter	Cable from ~LKR 3,500
iPhone 14 or older (Lightning)	Lightning to HDMI adapter — but see the Netflix warning	Adapter from ~LKR 4,000
Android flagship with DisplayPort Alt Mode	USB-C to HDMI cable or adapter	Cable from ~LKR 3,500
Android mid-range or budget	No cable will work. Use a streaming stick	Stick from ~LKR 7,000

1. USB-C to HDMI — only if your phone supports video out

A USB-C port does not automatically carry video. Sending a picture down it requires DisplayPort Alt Mode, a capability the phone maker either builds in or doesn’t. Charging and file transfer tell you nothing about it.

• All iPhone 15 and newer models support it, at up to 4K. Apple confirmed DisplayPort output is built into the USB-C port across the whole iPhone 15 range.
• Many Android flagships support it — Samsung’s Galaxy S and Note lines (the same feature that powers DeX), and most premium models from the major brands.
• Most mid-range and budget Android phones do not, and this cannot be added later. No adapter, app or setting will enable it.

If the phone lacks it, a USB-C to HDMI cable does nothing at all: no picture, no error message, just a blank screen. Look up your exact model and search its specification for “DisplayPort Alt Mode” or “video output” before you buy. If you can’t find a clear answer, assume it doesn’t have it.

2. Lightning to HDMI — and the Netflix problem

For an iPhone 14 or older, a Lightning to HDMI adapter mirrors the screen at 1080p. Photos, YouTube, your own videos, games and presentations all work.

Streaming subscriptions often don’t. Netflix, Disney+, Prime Video and similar services enforce HDCP copy protection along the entire chain — phone, adapter, cable, TV. Apple’s own Lightning Digital AV Adapter negotiates it; uncertified third-party adapters generally do not, so the app opens, you press play, and you get a black screen or a protection error.

We stock third-party Lightning adapters and they are good value for mirroring, photos and YouTube. They are not the right buy if the whole point is watching Netflix on the TV. For that, either buy Apple’s own adapter or — much cheaper and better — use a streaming stick.

This is worth being blunt about because the adapter costs around LKR 4,000–5,600 and the disappointment only arrives after you’ve opened the packet.

3. A streaming stick — the answer for most households

A Fire TV Stick or Chromecast plugs straight into the TV’s HDMI port, joins your WiFi and runs Netflix, YouTube and the rest itself. Your phone becomes the remote, or isn’t involved at all.

That solves every problem above at once:

• It doesn’t care what phone you own, or whether it has DisplayPort Alt Mode.
• It handles copy protection properly, so streaming apps just work.
• Your phone stays free — no cable tethering you to the TV, no battery drain, no interrupting the film to answer a message.
• It turns an older TV into a smart TV rather than turning your phone into a video player.

If the goal is “watch Netflix on the big screen”, this is almost always the right purchase, and it is often cheaper than the certified adapter.

What about older TVs with no HDMI?

If the television only has the round red/white/yellow sockets, you need an AV to HDMI converter — but note the direction. Most converters on the market go AV in, HDMI out, which is for putting an old DVD player onto a new TV. Going the other way (HDMI source into an AV-only TV) needs a converter built specifically for that, and the result is standard definition regardless of what you feed it.

On a TV that old, a streaming stick won’t help either — it needs an HDMI port. Be realistic about what the screen can show before spending anything.

Getting the sound right

Over HDMI the audio travels with the picture, so the TV’s speakers take over on their own. Two exceptions catch people out:

• HDMI to VGA adapters carry no sound. VGA is a video-only standard. If you’re connecting to an older projector or monitor, buy an adapter with a separate 3.5mm audio output and run that to speakers.
• The TV may stay on its own input. If there’s no sound, check the TV’s audio source setting before assuming the cable is faulty.

Before you buy, check these four things

1. Does your phone actually support video out? For anything other than an iPhone 15+, this is the question that decides everything.
2. Is streaming the point? If yes, a stick beats an adapter for iPhones on Lightning.
3. How far is the sofa from the TV? Cables come in 1m, 1.5m and 2m; a 1m lead will have you sitting on the floor.
4. Do you need to charge at the same time? Only some adapters have a pass-through power port.

If you’re unsure which of these applies to you, put the question in the note field when you order and we’ll confirm the right part on the phone before it ships.
