• View photos and home videos – Check out your entire photo library on your TV‘s display.
• Use TV as a monitor – Use your TV screen as a monitor for your laptop when traveling.

The benefits are many, and you have several wired and wireless options to choose from. Now let‘s look at how to make the connection.

HDMI – The Gold Standard

For connecting a computer to a TV, HDMI is the gold standard. HDMI cables can transmit uncompressed ultra high definition video along with multichannel digital audio. Here‘s a quick rundown:

• Supports resolutions up to 4K at 60Hz.
• Bandwidth up to 18Gbps depending on HDMI version.
• Carries both audio and video signals.
• Backward compatible with previous HDMI versions.

If both your PC and TV have HDMI ports, this is by far the easiest option:

1. Use HDMI cable to connect PC and TV HDMI ports.
2. Set TV input to associated HDMI port.
3. Configure PC to detect TV and extend or duplicate display.

With widespread adoption, low cost, high bandwidth, and simplicity, HDMI is the top choice for connecting PCs and TVs. But what if one or both of your devices lack HDMI? Let‘s explore some alternatives.

VGA – Video Only Connection

The VGA connection has been around since the days before high definition video. While limited to analog signals, it can still be handy for hooking up a PC to an older TV:

• Maximum resolution of 1080p but no audio signal.
• Requires a 3.5mm audio cable for sound.
• Most modern GPUs still include a VGA output.
• TV needs a VGA or "PC input" port.

To use VGA:

1. Connect VGA cable between PC graphics card and TV VGA port.
2. Use 3.5mm audio cable from PC to TV for sound.
3. Power on and select VGA input source on TV.
4. Configure PC to detect TV and extend or duplicate display.

While limited to 1080p resolution, a VGA connection along with a separate audio cable can provide video and sound without HDMI.

DVI – Transitioning from Analog to Digital

Like VGA, DVI has been around for many years, serving as a bridge from analog to digital video:

• Maximum resolution of 1080p without audio like VGA.
• Some variants support digital signals but not analog.
• Easy conversion to HDMI with simple passive adapter.
• Rarely used today but found on older graphics cards.

To utilize DVI:

1. Use DVI cable to connect PC DVI port to TV.
2. Add 3.5mm audio cable between PC and TV.
3. Power on devices and select DVI input on TV.
4. Configure PC to detect TV and extend or duplicate desktop.

Similar to VGA, DVI can be paired with a 3.5mm audio cable. Or you can convert to HDMI easily with an inexpensive passive DVI to HDMI adapter.

DisplayPort – Primarily for Monitors

DisplayPort is a more modern digital connection primarially designed for high resolution computer monitors:

• Capable of up to 8K resolution at 60Hz.
• Newer version 1.4 supports HDMI 2.0 features.
• Typically only found on dedicated PC monitors.
• Can convert to HDMI using active DP-HDMI adapter.

Setting up DisplayPort:

1. Connect DisplayPort cable between PC DP and TV DP ports.
2. Or use active DisplayPort to HDMI 2.0 adapter.
3. Configure PC to detect TV and extend or duplicate display.

DisplayPort is less common among TVs but offers high resolution and can convert to HDMI if needed.

USB-C – The Future of Connectivity

The reversible USB-C connector has become more prevalent on both computers and TVs over the past few years. USB-C supports video signals via the Alternate Mode protocol:

• Supports up to 4Kp60 with HDR when using HDMI Alt Mode.
• Lower latency than wireless streaming options.
• Requires USB-C port on both PC and TV.
• Cables are inexpensive and easy to find.

Connecting via USB-C:

1. Use USB-C cable between computer USB-C port and TV.
2. Power on devices and select USB-C input on TV.
3. Configure PC to detect TV and extend or duplicate display.

As adoption of USB-C increases, it offers a simple and high quality wired connection option between your devices.

Wireless Screen Mirroring

If your computer and TV support wireless display standards like Miracast, you can connect them without any cables:

• Latency is higher than wired options – not ideal for gaming.
• Limited to 1080p resolution typically.
• Both TV and PC must have compatible wireless software/hardware.

Setting up a wireless connection:

1. Enable wireless display software like Miracast on Windows PC.
2. On TV, select the Miracast input source.
3. On PC, connect to TV and extend or duplicate display.

Wireless screen mirroring avoids cables at the cost of higher latency. Great for occasional streaming.

Chromecast – A Popular Streaming Stick

While not technically connecting your computer directly, Chromecast is a very popular streaming device:

• Streams content from smartphone apps or Chrome browser tabs.
• Max resolution of 1080p.
• Latency too high for gaming or using as a monitor.
• No video/audio cables required.

Setup steps:

1. Plug Chromecast into HDMI port on TV.
2. Connect phone or laptop to same WiFi network.
3. Cast content from compatible apps to the TV.

Chromecast offers an easy way to wirelessly stream entertainment content from your computer to the TV.

USB to HDMI Adapters

If your TV has HDMI but your computer lacks it, USB to HDMI adapters can come to the rescue:

• Allow HDMI connection for PCs without native HDMI-out.
• Require USB video driver installation on host computer.
• Resolution limited to 1080p for USB 2.0 or 4K for USB 3.0.
• Select an active/powered adapter for best performance.

Steps to use a USB video adapter:

1. Install drivers for USB adapter if required.
2. Connect USB end of adapter to computer.
3. Connect HDMI end to TV HDMI port.
4. Configure PC to detect TV and extend or duplicate display.

USB to HDMI adapters allow older computers without native HDMI to connect with modern TVs.

Audio Options

When using analog connections like VGA or DVI, audio signals are not transmitted. But you have a few options to get sound:

• 3.5mm audio cable – Carries analog stereo audio to TV or speakers.
• HDMI audio extractor – Extract HDMI audio to pass via 3.5mm cable.
• USB audio adapter – Add USB sound card to allow audio over VGA/DVI.
• Optical/SPDIF – Extract digital audio from HDMI to optical output.

So with the right cabling, you can handle audio even when using older video outputs.

Resolution and Refresh Rate

When connecting your PC to a TV, consider the resolution and refresh rate:

• 1080p at 60Hz is common base level performance.
• 4K at 30Hz sufficient for video and media playback.
• 4K at 60Hz recommended for gaming or PC monitor use.
• Matching native resolution of TV avoids scaling lag.

Here are the max resolutions for different connections:

Interface	Max Resolution
HDMI 2.1	10K at 120Hz
HDMI 2.0	4K at 60Hz
DisplayPort 1.4	8K at 60Hz
USB-C Alt Mode	4K at 60Hz
VGA	1080p at 60Hz

Aim for the native resolution of your TV and the fastest refresh rate supported by both devices.

Reduce Display Lag for Gaming

When connecting a PC to a TV for gaming, display lag can ruin the experience:

• Use a wired connection like HDMI or DisplayPort when possible.
• Enable Game Mode on your TV to disable post-processing.
• Match native TV resolution and turn off scaling.
• Use faster refresh rates up to your TV‘s max capability.

Following these tips will ensure you have the smoothest, most responsive big screen gaming experience possible.

Extending vs Duplicating Displays

Once connected, you‘ll need to configure your PC to work with the TV display:

• Duplicate – Mirrors your main display onto the TV.
• Extend – Treats the TV as a second monitor to extend your desktop.
• Projector Only – Shows image on TV/projector but not PC display.

Try both extending for a giant desktop and duplicating for easy streaming to your TV.

Troubleshooting Guide

If you are having issues getting your PC to show on the TV screen, here are some troubleshooting tips:

• Use the correct input source on the TV such as HDMI 1, HDMI 2, etc.
• Try replacing the video cable in case of a faulty cable.
• Update your graphics card drivers and TV firmware.
• Disable power saving mode on PC and check sleep settings.
• Adjust resolution and refresh rate settings on PC and TV.
• Try a different video output connection on your PC.

With the right troubleshooting, you should be able to sort out any issues getting your computer screen to show up on the TV display.

Ready for the Big Screen
