HDMI vs DisplayPort vs DVI vs VGA – every connection explained

display_connectors_0

Most monitors will have a range of different inputs available, and your PC or laptop will also use different outputs, so it can be difficult to decide which is the best one for you to use. Under most general circumstances, you might be able to get away with using whichever cable you have lying around, but if you have more specific needs, such as carrying audio or using high resolutions or refresh rates, you’ll need to be more discerning in your choice of cable. We outline the different cables below and give you a few different usage scenarios to help you decide.

HDMI 

HDMI, or ‘High-Definition Multimedia Interface’ to use its full name, is one of the most common connections. You’ve probably come across it on your television, set-top boxes, tablets, laptops and games consoles.

HDMI is unique among the many connection options in that it’s able to carry both uncompressed video and uncompressed audio. This is why it’s become the connection of choice for most multimedia devices as it’s a one cable solution (like SCART but so much less annoying). Other benefits of HDMI include functions such as HDMI-CEC (HDMI Consumer Electronics Control), which allows you to control numerous devices with one remote. For example, connect a soundbar to your television through a HDMI-CEC compatible port and the soundbar can turn on and off with your television and be controlled by a single remote.

HDMI has seen numerous revisions since its inception in 2002. Its most common version, used in most consumer devices at present, is 1.4 but there’s a newer, more exciting 2.0 specification now becoming more prominent. The main difference between the 1.4 and 2.0 specifications focus around bandwidth available. HDMI 1.4 has a bandwidth maximum of 10.2 Gbps/s whereas the HDMI 2.0 tops out at 18 Gbps/s.

The reason that bandwidth becomes important is due to the advent of 4K content. Due to the limited bandwidth of HDMI 1.4, only 24fps was possible at 4K resolution (3,840 x 2,160). Now, thanks to the extra bandwidth available in the 2.0 specification, up to 60fps at 4K resolution is possible.

Colour depth is also another area where the new HDMI 2.0 specification gains some advantages. Where 1.4 was limited to 8-bit colour, HDMI 2.0 has 10-bit or 12-bit available. This is important for when High Dynamic Range (HDR) content becomes available.

HDR can be described as the ratio between the lightest and darkest parts of an image. Typically, with standard dynamic range, you’re losing detail at either end of the light spectrum. Expose a scene for the shadow detail and you end up with blown out highlights, or expose for the highlights and you lose shadow detail. HDR allows a greater range of detail across the full light spectrum.

You’ve probably already come across HDR through photography. Most smartphones now have an HDR mode where they essentially take numerous images at different exposures and combine them. As HDR has become part of the Ultra HD standard, you can expect more Ultra HD Blu-ray content to take advantage. The likes of Amazon and Netflix are going to be streaming HDR content as well.

More often than not, if you’re connecting something to a television, HDMI will be your best, and likely only, bet. Most PC monitors will also include an HDMI input. The good news, where it comes to 1.4 vs 2.0, is that you don’t need to rush out and buy new cables. To take advantage of the 2.0 specification you just need both devices on each end of the cable to be 2.0 compatible. Any HDMI cable will do, and we’ve already seen that there’s no difference in HDMI cable quality.

The one thing to look out for are the different HDMI connection sizes. Not only is there full-size HDMI (Type A), but you can come across Mini HDMI (Type B) and Micro HDMI (Type C), too. These are commonly found on portable devices such as tablets, camcorders and action cameras, where their physically smaller connections are required. You can either buy HDMI-Mini HDMI/HDMI-Micro HDMI cables or you can buy Mini/Micro HDMI adaptors so you can use your full-size HDMI cables.

DisplayPort

mini_displayport

Until HDMI 2.0 became a standard, DisplayPort had it beat when it came to high-resolutions. DisplayPort 1.2 has long been able to carry 3,840×2,160 resolution video at 60fps (or a refresh rate of 60Hz) and is the most common DisplayPort specification on most consumer monitors and devices now. This has 17.28 Gbit/s of bandwidth. A newer 1.3 specification is becoming more widely available, however, and this opens the floodgates to higher resolutions such as 7,680×4,320 (8K).

er_photo_149281

The main advantage of DisplayPort is the ability to output to multiple displays through Multi-Stream Transport (MST). You can do this by daisy-chaining compatible monitors over DisplayPort or by connecting a DisplayPort MST splitter to your single DisplayPort output on your PC or laptop. You have to work within the bandwidth limitations of whichever DisplayPort specification you’re using, such as two 1,920×1,080 monitors over 1.2 or two 3,840×2,160 displays over the DisplayPort 1.3 specification. As such, DisplayPort is often a great choice for those looking to use multiple monitors.

DisplayPort also has advantages where it comes to screen refresh rates through Adaptive Sync. This is what AMD has used for its Freesync implementation. Essentially this helps reduce screen tearing, which will be of particular interest to gamers. Like HDMI, some laptops and devices use Mini DisplayPort, so make sure you get the right cable.

DVI

DVI stands for ‘Digital Visual Interface’, and is another common connection found on PC monitors. Things can become a little confusing when you consider there are three different types of DVI. There’s DVI-A (analog signal), DVI-D (digital signal) and DVI-I (integrated analog and digital signal). Not only that, but DVI-D and DVI-I have single-link and dual-link versions. Nowadays, DVI-A is very uncommon, as it’s no better than VGA.

dvi

The differences between single-link and dual-link refer to how much bandwidth the cable can carry. A single-link DVI-D or DVI-I cable can carry 3.96 Gbit/s, which tops out at 1,920×1,200 resolution. Dual-link, on the other hand, physically has extra pins on the connectors, allowing a maximum bandwidth of 7.92 Gbit/s and 2,560×1,600 resolution.Although DVI is still a common connection, it’s becoming dated, so if you want to output a very high resolution you’ll need to use HDMI or DisplayPort instead.

VGA

8

VGA is the oldest of the four connections outlined in this article. It’s been around for decades, dating back to the days of thick, heavy CRT monitors of yesteryear. VGA stands for Video Graphics Array but can also be referred to as an ‘RGB connection’ or ‘D-sub’. While VGA can technically output to 1,920×1,080, the problem is that it’s an analog connection, so as you push the resolution higher you get image degradation as the signal is converted from analog to digital. Unless you absolutely have to, use one of the above connections instead of VGA.

Using a combination of HDMI, DisplayPort, DVI and VGA

6010a

Most motherboards and dedicated graphics cards will have multiple outputs. You can use a combination of these to output to multiple monitors. So if you have HDMI and DVI outputs, connect one monitor using HDMI and the other using DVI. As mentioned above, if you’re using DisplayPort and your graphics card or device supports Multi-Stream Transport, you can daisy-chain DisplayPort monitors, too.

Any questions regarding article give me a call. I am available M-F from 10:00am-6:00pm and Sat 11am-3pm. I also sell video cards with various connections to suit your needs.

Crucial MX200

crucial-mx200

THE GOOD The Crucial MX200 includes helpful enterprise-class features rarely available in consumer-grade SSDs. It should last a long time, and it delivers fast performance.

THE BAD The three-year warranty is short, and the drive is a bit more expensive than its competitors.

THE BOTTOM LINE For heavy storage users who also need a high level of data safety, the Crucial MX200 is an excellent buy. 

The Crucial MX200 is a mid-tier solid-state drive, rivaling the recently reviewed Samsung SSD 850 Evo as an excellent storage upgrade.

The new SSD has significantly higher durability, especially the 1TB capacity, and includes enterprise-grade data security features. In testing, it was also faster than the Samsung in certain categories.

I feel comfortable recommending the drive to anyone. The MX200 has enough power to make any hard drive-based computer perform much faster. And the ultra-high endurance means you can regularly use it for heavy tasks, such as HD video editing, without having to worry about quickly rendering it useless.

A consumer drive with enterprise features

The MX200 is a 2.5-inch standard internal drive, with a design similar to most other SSDs and laptop hard drives. It supports SATA 3 (6Gbps) and works with earlier revisions of the SATA standard.

On the inside, however, it’s the first such drive I’ve seen with a number of high-end features, normally found only in enterprise-class SSDs, that keep its stored data safe. These features include Exclusive Data Defense hardware encryption, and RAIN.

RAIN is a technology that allows a portion of the SSD’s flash memory to be dedicated as parity. This means when data is saved on the drive, it’s dispersed to multiple different storage components. As the result, if one storage component fails, you can still retrieve data from other components. And to reduce the chance of data corruption, each storage component has four layers of Exclusive Data Defense.

The MX200 supports AES 256-bit hardware encryption that is TCG Opal 2.0- and IEEE1667-compliant. This makes it fit in business environment where data security in case of theft or loss is important. On top of that the drive also features power-loss protection, adaptive thermal monitoring, TRIM, SMART and DevSleep, which enables it to use very little power.

ULTRA-HIGH ENDURANCE, HELP SOFTWARE

The Samsung SSD 850 Evo has impressive endurance, but the MX200 tops that by a large margin. Endurance, also known as program/erase (P/E) cycles, is the rating that quantifies the total amount of data that can be written to an SSD before the drive becomes unreliable. You can think of endurance as the drive’s durability.

Generally endurance increases with capacity: the MX200 is available in 250GB, 500GB and 1TB capacities that have respective endurance ratings of 80TB, 160TB and 320TB. Particularly with the 1TB drive, you’d have to write 40GB of data to it per day, every day, continuously for 22 years before it became unreliable.

Note that an SSD’s endurance relates only to writing, as reading doesn’t affect its life span at all. Also, 40GB is quite a lot of data. On average, most days we don’t write even a fraction of that to our computer’s main drive, and many days we don’t write anything at all.

Nonetheless, the high endurance allows pro users to use the drive for heavy tasks that involve lots of data writing, such as video editing or data swapping. If you get the 1TB capacity, it’s safe to say that you can use it without having to worry about abusing its P/E cycles.
