What is the difference between VGA vs HDMI?

VGA vs HDMI are interface requirements used for cables that link gadgets – such as laptop and DVD gamers – to a screen, like a TELEVISION, computer monitor or projector.

VGA is an older standard that brings just a video signal. HDMI is the default cable standard for more recent electronic gadgets, such as Blu-Ray gamers or LED TVs. HDMI can carry both digital video and audio signals, all while securing information with HDCP.

The video quality obtained with a VGA cable is visibly worse when compared to that of HDMI. Nevertheless, HDMI may be phased out soon, as USB 3.1’s versatile Type-C connector has the possible to replace the HDMI standard.

First, we need to see what is VGA and HMDI.

What is VGA?

VGA is short for Video Graphic Variety. Initially, it described display interface hardware manufactured by IBM and used in IBM PS/2 line of desktop computers starting from 1987.

Video Graphics Selection (VGA) was the basic video cable for computers when it was first released in 1987 and are easily recognizable by their blue 15-pin ports. At that time, the supported resolution was 640×480 but ultimately broadened in phases up to Ultra Extended Graphics Range (UXGA) in 2007. UXGA might support 15″ monitors at 1600×1200 pixels.

What is HDMI?

High Definition Multimedia User Interface (HDMI) was developed in 2002 and soon ended up being the brand-new requirement for computing. The highlight provided by HDMI that no other video cable could offer was the ability to transfer audio in the same cable as the video signal. HDMI supports HD video at 1920×1200 pixels and 8 audio channels.

Few devices support VGA anymore. You’ll find many computers and Televisions have an HDMI connection and no VGA connection. You might have a requirement for a VGA cable if you still use older technology like older projectors or older video game consoles.

5 Different Video Cables

5 Different Video Cables

HDMI: Audio and video signal, finest for TELEVISION to PC connections

DVI Cable: Video only, ideal for older systems or for 144Hz at 1080p DisplayPort Cable (DP): The very best connector for an audio and video signal, and can transmit 144Hz as much as 4K resolution

VGA: Old, legacy video connector. Only to be used when absolutely nothing else available

USB Type-C: Latest audio, video, information and power connector. The best connection for laptops and mobile devices

Modern Monitors Use HDMI

If you still have an older screen with a VGA connection, you will have a need for a VGA cable. Nevertheless, you likely will require a VGA to HDMI converter to link to any modern monitors. If you’re using a screen constructed from 2000 through 2006, you’ll likely require a VGA to DVI converter.

Nevertheless, given that VGA can’t transfer HD video signals to more recent displays like HDMI can, even with a converter you’ll observe the significantly degraded video. If you’re utilizing a newer computer with an older display that has a VGA connector, there are HDMI to VGA converters readily available too.

Audio: HDMI Supports High Definition Audio Signals

VGA can only transfer a single video signal without any audio, while HDMI can transfer approximately 32 channels of digital audio. HDMI supports most high definition audio signals like Dolby Digital, DTS, and DST.

If you utilize a VGA to HDMI converter to display from an older computer system to a more recent display, you’ll still need a second audio cable to send noise.

If you utilize an HDMI to VGA converter to show from a newer computer to an older display, a 2nd audio cable is still needed if the screen supports sound. If it doesn’t, you’ll need to link your computer system’s audio to different speakers.

Comparisons HDMI vs VGA: Data Transfer Speed

VGA

  1. Optimum refresh rate of 85 Hz.
  2. Less input lag.
  3. More signal interference.
  4. Not hot-pluggable.

HDMI

  1. Optimum refresh rate of 240 Hz.
  2. Minor input lag.
  3. Almost no signal disturbance.
  4. Hot-pluggable.

An HDMI cable has 19 or 29 pins and sends video and audio. HDMI 2.0 is capable of attaining 240 Hz at 1080p resolution. VGA on the other hand has 15 pins and uses an RGB analog video signal. This analog signal is just capable of a refresh rate from 60 Hz to possibly 85 Hz.

Another substantial distinction is that you can unplug and plug in an HDMI video cable while the computer is switched on and the video cable is sending (hot pluggable). You can’t do this with VGA. You ‘d require to stop the video device stream or turn off the computer prior to plugging in the VGA cable.

The one benefit to VGA’s analog signal is that there’s no post-processing of digital signals, which means there will be no “input lag“. In the case of HDMI, the information transfer and revitalize rates are so much greater that this input lag is insignificant by contrast.

VGA signals are also subject to considerable signal disturbance from outdoors sources like microwaves or cellphones. HDMI cables are far less susceptible to this, and with thick protecting nearly completely impervious to disturbance.

Another comparison that helps us to understand HDMI vs VGA is compared DVI.

What’s the difference between DVI and VGA?

The basic differences between them stem from their age. A DVI Connection is a considerably newer connection type that transfers digital signals while VGA is older and transfers analog signals.

But DVI and VGA are a lot more than a jumble of letters, they are specific types of connections that can make a huge impact on your picture quality. Read on for an in depth look at what they are and how they work.

First, we’ll dive into VGA, to explore how this technology made its mark and the reasons why it’s being replaced by other modern connections.

Leading Advantages of DVI vs VGA for Computer Monitors

When you want to connect your computer to a bigger external monitor or TV to make your movie night or presentation more visually dazzling, you’ll have to determine what ports are on your device. Your PC could have any number of ports but some of the most common include HDMI, DisplayPort connector, DVI, USB, and VGA ports.

After you identify your port, you’ll need to choose the right connector to attach your devices. But it’s not always a straightforward process, especially if you need a cable that converts different signals. For example, you might need a specific converter to transfer the analog signals from a VGA port to an external monitor that uses a digital DVI interface.

In order to maximize the quality of the image you see, you’ll want to make the right choice when it comes to your connections. Below, we will dive into the difference between two common kinds of connections: DVI and VGA.

What is VGA vs HDMI vs DVI?

VGA, or Video Graphics Range, is thought about as an old-school innovation. In fact, it is among the oldest connection requirements found on the market today. It was first developed by IBM and presented to the world in 1987 It was commonly used for video cards, computer screens, TV sets, and laptops.

These days, it’s considerably harder to find VGA ports, cables, and ports since they are being changed by updated user interfaces like DVI, HDMI, and DisplayPort.

VGA pins

VGA features a fifteen-pin connector with three rows of five pins. A VGA interface on a desktop or laptop computer has an equivalent variety of pinholes that make for a complementary connection with a VGA cable.

Each pin on a VGA cable has an unique function. For instance, the very first pin transfers the color red, the second pin transfers green, and the 3rd pin transfers blue [ 3]

VGA converters

If you have a VGA display or video card, you’ll likely want a VGA converter. Why?

You turn over the display to see what sort of connections it uses and you recognize it just has an HDMI connection. Now, your two gadgets aren’t suitable. This indicates you either need to get a new video card or get a various monitor. Or, you can merely prevent that hassle and buy a VGA converter.

The complicated part of this scenario for users is trying to determine what type of converter you really need.

VGA to HDMI converter: This will alter your VGA signal from your desktop or laptop computer to the HDMI port on a display, either for a monitor or a TV. You’ll require this converter if your device has a VGA port on the video card, but you want to use an HDMI input monitor or TV as the screen.

There are VGA to HDMI converters available that have a USB cable integrated inside it to carry an audio signal alongside the video signal. This is particularly useful because VGA doesn’t transfer audio by itself, so with this special converter, you can play sounds in a display with speakers.

HDMI to VGA converter: This kind of converter links a video card with an HDMI connector to a display or TV that has a VGA input connection. Due to the fact that HDMI is a more recent technology than VGA, an HDMI to VGA converter is a great addition you can utilize to link a newer laptop computer or desktop PC to a more outdated monitor or display screen.

VGA to DVI converters

You’ll require a DVI to VGA converter if you want to make a connection between a graphics card with DVI to an external display screen or monitor that only has a VGA port.

DVI to VGA converters: These converters are generally DVI male to VGA woman. This simply indicates that the DVI end of the converter is placed into the DVI port in your video card. As you may anticipate, the VGA end of the converter is utilized with a male-to-male VGA cable to connect the converter to the female end of the external screen device.

VGA to DVI converters: This kind of converter exists but it’s substantially more difficult to find. You’ll require this kind of converter to move video from a VGA video card to a DVI external screen.

Keep in mind:

DVI to VGA converters work by transferring the signal from digital to analog. DVI pins can bring both analog and digital signals. VGA transfers just analog so going from VGA to DVI makes a converter necessary to take those analog signals and convert them to digital connection signals.

DVI vs VGA

VGA ports are being phased out but you can still discover them in some projectors, in addition to older screens and TVs. The main concern with a VGA connection comes from the reality that most of today’s screen gadgets use a digital user interface. When a VGA signal is transformed from analog to digital, it results in lower quality video compared to DVI.

In addition, VGA supplies a maximum resolution of 640 x 480 with a refresh rate of 60 Hz while a DVI connector can boast a resolution of approximately 1920 x 1200 pixels for single-link format or 2560 x 1600 resolution for dual-link format With other connections like DVI and HDMI available, VGA is a nearly obsolete technology because of its constraints.

DVI vs VGA: How do you tell them apart?

VGA ports and ports are constantly blue-colored while DVI connectors are constantly white.

VGA vs HDMI Frequently asked questions

Here are the most frequently asked questions regarding how HDMI compared to VGA and vice-versa.

What is the difference between HDMI and VGA?

VGA is analog and HDMI is digital, making the latter head-over-heels much better than VGA. VGA is also the older A/V standard of the two. A/V is mostly used for computer display connections while HDMI is mainly associated with HDTV (although it’s also been utilized for HD computer monitor connections as of late).

What is the Advantage of Using HDMI Over VGA?

HDMI uses video and audio signals in one cable while VGA just transfers video signals. HDMI quality is far greater, even when it concerns 1080p HD that both VGA and HDMI can bring. HDMI also supports higher resolutions, with HDMI 2.1 being capable of running 10K video at 120 Hz with HDR consisted of. Not to mention, VGA does not have the handshake technology of HDMI CEC and the audio technology of HDMI ARC and eARC.

How to connect HDMI laptop computer to VGA projector?

To connect an HDMI laptop computer to a VGA projector, you need to obtain an HDMI to VGA converter. Some converters even push the VGA to at least bring 1080p HD video signals. There are converters that can split the video and audio signal of the HDMI source media while others only bring the digital signal to transform it to VGA.

How do I connect my VGA laptop computer to an HDMI projector?

A VGA laptop computer that only has a VGA port can be connected to an HDMI projector using a VGA to HDMI converter. There are limitations to how high the quality of the connection and upscaled video is due to the nature of VGA, which is an older video requirement from 1987.

How do I connect HDMI to VGA with audio?

You can get an HDMI to VGA converter that doubles as a signal splitter considering that VGA only carries video signals. It needs to have audio ports for 3.5-millimeter audio jacks or coaxial audio cable televisions. Otherwise, you’ll need to utilize your computer’s own speakers for sound.

How to connect the laptop to a projector with HDMI?

You require either a laptop with an HDMI port or a laptop with a VGA port so that you can connect a VGA to HDMI adapter or converter with it in order to make a laptop to HDMI-based projector connection possible. Audio cable televisions used independently, although it’s much better to utilize a separate laptop or Bluetooth speaker than to utilize a projector’s integrated speakers.

How to link the laptop to a projector with VGA?

To link a laptop computer to a projector with VGA, you can either utilize the VGA port available to most laptop computers made till 2010 and even beyond that or you can get an HDMI to VGA converter if it’s a laptop with just an HDMI port.

Does a VGA to HDMI cable bring sound?

No. VGA just sends video signals. You can either utilize PC speakers for your noise or acquire different audio cable televisions to link your laptop/desktop to a stereo or soundbar. You can utilize Bluetooth wireless speakers instead. When browsing for converters/adapters to use, you can select between those that bring just the VGA cable or have additional audio jacks to link your audio to the HDMI cable.

Does HDMI to VGA work both ways?

No. HDMI to VGA connections using a converter, splitter, or adapter just works one way-an HDMI source media converter linked to a VGA video signal for older computer system monitors and projectors. To link a VGA source media to an HDMI display screen, you require a separate HDMI to VGA converter. You also need separate cable televisions for the split audio. For HDMI source media, you require a splitter that divides the HDMI signal into VGA video and 3.5 millimeter jack/coaxial cable audio.

Does the HDMI to VGA adapter need power?

Adapters or converters that are HDMI to VGA typically do not require additional audio or USB power unless they’re splitters that have additional audio ports readily available. If you’re using a converter that links a VGA source to an HDMI display screen and has audio ports on it to permit you to link to a speaker or soundbar as well, such units need USB power. In other words, it’s usually the VGA to HDMI connection that rather requires that additional USB power.

Can VGA bring HD video?

Yes, however, it has certain limits. You can use VGA to carry HD video the same way its analog TV variation of YPbPr or element video can replicate HD through the 1080i (interlaced instead of 1080p, which is progressive scan). SVGA is usually limited at 480p however later variations had high sufficient transmission bandwidth to transfer resolutions reaching 1080p Full HD and even greater like 4K. Not bad for a requirement made back in 1987.

Is HDMI better than VGA? If so, why?

HDMI is much better than VGA in more methods than one, starting with the reality that it’s digital signal and provides much clearer, greater resolution picture quality. VGA originates from the bygone period of analog, standard-definition connections (despite the fact that it can also do HD). Unlike the video-only VGA, HDMI can carry different audio types from DTS-HD to Dolby True HD.

How do you check the HDMI cable version?

Ask the vendor for particular cable versions. Some cables have labels while others do not. There’s no other way for your computer system to spot the cable version either. Use the guide above to know which cable type to request. There are no HDMI 1.3 cables or the like. Normally, they’re offered by how high the resolution they can carry. You have standard HD cables, 4K cable televisions, or 48G cables (the fastest cable presently available).

Is VGA capable of 1080p?

Yes, VGA is capable of 1080p resolution HD video. As covered in the HD video question, VGA can do what it’s part video equivalent could. Because of cable length and quality, you could experience a step of picture quality destruction you will not get from utilizing HDMI cables instead. There is a bit of artifact with VGA HD also, but at a quick look, the HD from VGA and HDMI are indecipherable from each other.

Do I require a special HDMI for 4K?

need a high-speed HDMI cable (HDMI 1.3 to 1.4 a) to do 4K at 30 Hz. For 4K at 60 Hz with HDR, you instead require a premium high-speed HDMI cable (HDMI 2.0/ a/b). For 4K at 120 Hz and anything beyond 4K, you need an ultra-high-speed HDMI cable or 48G cable (HDMI 2.1). A standard HDMI cable is incapable of providing uncompressed data of that quality. You have to select on your BD player to downscale the 4K signal to 1080p so that it can pass through a standard HDMI cable (the cable will not be doing the downscaling).

Our Conclusion:

VGA versus HDMI is an unreasonable contest. Naturally, HDMI wins against VGA in every category, including the method they have the ability to parse 1080p and greater signals (VGA can hardly do Full HD, much less 4K resolutions at any higher than 30 Hz). Nevertheless, VGA is still in the conversation unlike the VHS versus DVD/Blu-Ray dispute due to the fact that it hasn’t been completely phased out and lots of contemporary computer systems are only just adapting HDMI as their video cable of choice.

If you’re utilizing a much older computer that just has a VGA port, you’re eventually going to have to use a VGA to HDMI converter to utilize more recent display screens. However, you’re never ever going to have the ability to enjoy the much greater detail and revitalize rates that a full HDMI port and cable offers.

The only time you may need to utilize a VGA cable is if you’re still utilizing older devices like vintage video gaming consoles. In this case you’ll want to keep a VGA cable with the device, in addition to the required converters.

Eventually, you’re going to wish to update your desktop or laptop computer to a newer one that uses the very best video output possible. You’ll discover that the latest video outputs use USB-C, but there are a lot of converters that enable you to output from USB-C to HDMI screens with no signal loss at all.
