Laptop Computer Video Output Guide
COMMON LAPTOP/ PROJECTOR VIDEO CABLE CONNECTOR PORTS:
This is a simple guide to help you determine which Video Cable type you need to connect your Laptop to a Projector or TV. For more information, contact the supplier of your PC or Mac laptop.
VGA is an old but popular video output that is still present on many PC laptops/ projector. VGA cables have a blue head with 15 holes in three rows of 5. It is often Blue or Grey in color.
Video Graphics Array, also known as D-sub, is a three-row 15-pin female connector, and was designed for universal reach and compatibility. Suitable for squarish monitors of the past.
VGA has a maximum Resolution of 2048 x 1536 pixels at 85Hz.
Today, it is found in low-end PCs, projectors, monitors, high definition televisions and so on. It is no longer commonly used, and is now being replaced with HDMI.
While it is capable of fairly high resolutions and frame rates, it’s an Analog signal (consisting of red, green, blue, horizontal sync, vertical sync video signals), so it will not give you pixel-perfect image with today’s LCD monitors/ Laptops.
HDMI is found on newer PC laptops. HDMI port have a flat, gold or silver head about 0.6 inches, or 1 centimeter across. It transmits Video & Audio, uncompressed Video data and compressed or uncompressed digital Audio data.
The DVI was exceeded by the High-Definition Multimedia Interface or HDMI, which is now the most common and well-known connectors for Laptop, Projector, TV and PC monitors. It provides better color than its predecessors, carries both audio and video signals, as well as supports 3D and Sync technology, which is why it is often used in home entertainment.
There are five types of connector used with HDMI. Type A, B, C, D and E. Also, HDMI comes in 3 Variants:
- HDMI 1.4 supports 4K at 30Hz, but does not support 21:9 aspect ratio;
- HDMI 2.0 supports 4K at 60Hz and can support 21:9 aspect ratio, but not HDR.
- HDMI 2.1 supports 4K, 5K, 8K and 10K resolution at 120Hz, as well as 21:9 aspect ratio and HDR.
DVI is found on some older PC laptops/ projectors. DVI port have a white head with 24 large holes, and 4 small holes. Often White or Cream in color.
The VGA was exceeded by the Digital Video Interface or DVI, which carries uncompressed Digital video. It comes in 3 different modes:
- DVI-I (integrated analog and digital signal)
- DVI-D (digital signal)
- DVI-A (analog signal) with single link and dual link variations.
Single link supports 1920 x 1200 pixels at 60 Hz refresh rate, while dual link supports 2560 x 1600 at 60Hz. You can achieve 4 K with dual link, but the refresh rate is halved at just 33Hz.
DVI-I is considered most preferable and versatile of them all, as it works with both digital and analog signals. comes in both single and dual link and supports higher resolutions
4. Display Port
Display Port is found on many PC laptops. is about the size of a USB connector. is a digital display interface developed by a consortium of PC and chip manufacturers.
Usually you’ll need a Display Port to HDMI adapter for TVs. HDMI’s competitor is DisplayPort or DP, which is backward compatible with previous ports, such as HDMI, DVI, through the use of either active or passive adapters.
It can be used to transmit audio and video simultaneously, although each is optional and can be transmitted without the other. Like HDMI, it offers better color than DVI and VGA , and carries both audio and video signals. DP also supports 21:9 aspect ration, 3D and Sync technology.
It is the first display interface to rely on packetized data transmission, a form of digital communication found in technologies such as Ethernet, USB, and PCI Express. Designed with direct graphics card/ monitor connection in mind, it transmits 4K resolution at 144Hz refresh rate, making it ideal for gaming and entertainment.
Thunderbolt is present on all newer Macbooks and iMacs. You’ll need an adapter to connect to a TV or projector.
A data, video & power connection on new Macbook & PC laptops.

Which connector is right for you?
For general home entertainment, HDMI is good option, as it supports decently high resolution and refresh rates. However, if you’re an avid gamer who is using a really high-resolution monitor, you’re better off with DP. This can make a real difference in your experience. And if you work professionally in graphic design, content creation, photography, video editing and so on, you will need a port that will support 4K resolution and a high number of pixels per inch to enable you to see all the details. While there are now wireless connections, traditional ports and cables are still a reliable, simple and inexpensive solution that remains popular.
