Bored of your small laptop screen? The simplest and most reliable way to connect your laptop to TV is with an HDMI cable. No Wi-Fi needed, no app required, no lag, no delay — just plug in and your laptop screen mirrors to your TV instantly.
This guide shows you exactly how to connect laptop to TV with HDMI cable in under 1 minute. Works on any TV brand — Samsung, LG, Sony, Mi, OnePlus — and any laptop running Windows, MacOS or Linux.
An HDMI cable costs as little as ₹100-200 and gives you a completely lag-free, zero-delay connection. Wireless screen sharing cannot match this speed.
Why Use HDMI Cable Instead of Wireless?
There are multiple ways to connect a laptop to a TV — Wi-Fi casting, Chromecast, Miracast, Samsung DeX — but HDMI cable is the best for most users because:
- Zero lag and zero delay — cables are always faster than wireless
- No app installation required — pure plug and play
- Works on any TV with an HDMI port — Samsung, LG, Sony, Mi, OnePlus, any brand
- Works on any laptop — Windows, Mac, Linux
- Audio also plays through the TV automatically
- No internet required — works even without Wi-Fi
- Perfect for movies, coding, trading, presentations, gaming
What You Need
- An HDMI cable (standard Type-A HDMI) — available for ₹100-200 online or at any electronics shop
- A laptop with an HDMI port (most laptops have one)
- A TV with an HDMI port (all modern TVs have at least one)
- TV remote to switch input source
⚠ If your laptop has a Mini HDMI, Micro HDMI, or USB-C port instead of full-size HDMI, you will need an adapter. Check your laptop’s port type before buying the cable.
How to Connect Laptop to TV with HDMI Cable — Step by Step
Step 1 — Connect the HDMI Cable to Your TV
Take your HDMI cable and plug one end into the HDMI port on your TV. Most TVs have 2-3 HDMI ports on the back or side. Remember which HDMI port number you used — HDMI 1, HDMI 2, or HDMI 3.
Step 2 — Connect the Other End to Your Laptop
Plug the other end of the HDMI cable into your laptop’s HDMI port. It is usually on the left or right side of the laptop. The connection is one-directional — one end is TV, other end is laptop.
Step 3 — Select HDMI Input on Your TV Remote
Pick up your TV remote. Press the Input or Source button (sometimes labelled as Input, Source, or a rectangle with an arrow icon). A list of inputs will appear on your TV screen. Select the HDMI port number you plugged into — HDMI 1, HDMI 2, or HDMI 3.
Step 4 — Your Laptop Screen Mirrors to TV Automatically
That is it. Your laptop screen will immediately appear on the TV — lag free, zero delay. No extra settings, no software installation needed. Audio will also automatically play through the TV speakers.
If the screen does not appear automatically on Windows, press Windows key + P and select Duplicate or Extend to set the display mode.
Windows Display Modes — Duplicate, Extend, or Second Screen Only
On Windows, press Windows key + P to choose how your screen appears on the TV:
- Duplicate — same screen on both laptop and TV (most common use case)
- Extend — TV becomes a second screen, extending your desktop (great for work and trading)
- Second screen only — TV shows content, laptop screen goes off (great for movies)
- PC screen only — only laptop screen, TV goes blank
What Can You Do After Connecting Laptop to TV?
- Watch movies and web series on your 40-50 inch TV screen — far better than a 15-inch laptop
- Trading — monitor multiple charts on a big screen without squinting
- Coding — extend your desktop to TV and have code on one screen, browser on another
- Gaming — play PC games on a big TV screen for an immersive experience
- Presentations — show your slides on TV for family, clients or students
- YouTube and streaming — better video and audio quality on TV
