So, you\u2019ve upgraded your graphics card<\/a>, your processor<\/a>, your monitor<\/a>, and more. Are your cables up to scratch though? <\/p>\n\n\n\n

\"Cables<\/figure>\n\n\n\n

Although an innocuous piece of kit, having an ancient cable is going to hamper your gaming more than you would think. Say goodbye to 4K resolutions, high bandwidths, and full colour. Without an up-to-date cable, you are going to miss out. The important question though, is which do you go for: HDMI or DisplayPort? You are in luck, we\u2019re here to break down the difference and which of these cables is best for you. <\/p>\n\n\n\n

\n\n\n\n

Cable Specifications<\/h2>\n\n\n\n

There are a few types of cable<\/a> that we use to connect our gaming PCs to a monitor. Today, we are focusing on the two gaming staples: HDMI <\/strong>and DisplayPort<\/strong>.  <\/p>\n\n\n\n

History of HDMI at a Glance <\/h3>\n\n\n\n

HDMI stands for High Definition Multimedia Interface, and this cable has been the industry standard for many years now. Developed in 2002 by big names like Hitachi, Sony, and Phillips, HDMI has been mass adopted across modern hardware \u2013 including GPUs and gaming monitors. As a result, HDMI cables come in a variety of sizes and lengths. <\/p>\n\n\n\n

Over the years, the technology has been developed to meet our ever-evolving demands for high definition viewing and gaming. The current standard, HDMI 2.1, can facilitate 8K (7680×4320) resolutions, refresh rates up to 240Hz, and maximum bandwidths of 48Gbps for the very best in visual experiences. <\/p>\n\n\n\n

Previous generations of HDMI technology are still widely in use, especially HDMI 1.4 and 2.0. Here is a breakdown of the specifications for previous generation HDMI standards <\/p>\n\n\n\n

Don\u2019t worry, we have a breakdown of HDMI 2.1 coming. We\u2019ll be pitting it against the latest standard from… <\/p>\n\n\n\n

History DisplayPort at a Glance <\/h3>\n\n\n\n

DisplayPort was designed by a collective of PC component manufacturers in 2008 with the goal to replace VGA and DVI. Whilst offering backwards compatibility with these ports, its specs are on par with HDMI and serves as an alternative to HDMI.  <\/p>\n\n\n\n

How it differs, DisplayPort cables utilise a packet data transmission system that requires much fewer pins. Similar to the transmission systems found in PCIe, this technology embeds micro packets of information into the data stream, thus allowing for higher resolution. Plus, it has great potential for future upgrades. Plus, in addition to carrying audio and video, DisplayPort is capable of bi-directional USB signals, whereas HDMI is not. <\/p>\n\n\n\n

Since launching nearly twenty years ago, DisplayPort technology has also evolved with the times. The current standard is DP 2.1, supporting resolutions up to 10,240×4320, refresh rates up to 1000Hz, and 80Gbps maximum bandwidths. But, much like HDMI, older standards are still widely adopted on hardware, especially DP 1.4. <\/p>\n\n\n\n

We have a breakdown of previous DisplayPort standards here for you: <\/p>\n\n\n\n

Latest Gens Compared: HDMI 2.1b vs DisplayPort 2.1<\/h3>\n\n\n\n

Both HDMI 2.1 and DisplayPort 2.1 offer amazing performance when it comes to your visuals. With high refresh rates and support for incredible resolutions, whichever you pick your gaming is going to be phenomenal.<\/p>\n\n\n\n

With Display Stream Compression (DSC) technology, you can achieve even higher refresh rates and resolutions, as it reduces the amount of data needed to be sent over the cable. <\/p>\n\n\n\n

From these tables, we can see that if you truly want to harness smooth 4K gaming<\/a> and above, then utilising HDMI 2.1 or DisplayPort 2.1 are a must. If you are gaming at 1440p and 1080p, you can game reliably on the older standards like HDMI 1.4 and DisplayPort 1.4. Just make sure your monitor resolution and connection support matches! <\/p>\n\n\n\n

Cables Specifications Explained <\/h2>\n\n\n\n

There are a few terms in these specification tables which might have you scratching your head. They are HDCP, HDR, and WGC. I\u2019ll briefly go into all these terms, to help you understand why they are awesome for your gaming experience. <\/p>\n\n\n\n

HDCP <\/strong>stands for High-bandwidth Digital Content Protection. This is copy protection and was introduced back in 2015. Currently, we are on version 2.3, although 2.2 is still widely used. What this means for you is that your content is protected from being copied. Livestreams cannot be recorded, Blu-rays cannot be copied, and you can safely enjoy your Ultra HD content with HDR support (2.3 onwards). All of the devices in your set-up require HDCP support. If one in the chain does not, then you may not get any audio or visuals. Equally, if you are mixing generations, then performance and protection features will be limited to the oldest generation present. <\/p>\n\n\n\n

HDR<\/strong> means High Dynamic Range, which allows your monitor to better display true-to-life colours. Those that are close to the human perception of brightness. This goes in hand with WCG<\/strong> which stands for Wide Colour Gamut. WCG allows for an increase in the variety of colours displayed onscreen. This is achieved with greater bit depth, making the RGB spectrum more vivid. Over a billion colours can be displayed with WCG. All three of these features are available on both HDMI and DisplayPort \u2013 from 2.0a and 1.4 respectively.  <\/p>\n\n\n\n

\"Demonstration
No HDR vs With HDR<\/figcaption><\/figure>\n\n\n\n

Developing this further is Dynamic HDR<\/strong>. Ordinarily, the parameters for brightness and contrast are static throughout playback. With Dynamic HDR, however, these can both be set per frame. This allows for better distinguishing between light and dark scenes, and more colours to display. The only drawback is that this is only available on DisplayPort 1.4 onwards. If only I had known about this during the Battle of Winterfell<\/em> episode! (Game of Thrones, 8.3 \u201cThe Long Night\u201d) <\/p>\n\n\n\n

What are the Standard Ports of Graphics Cards? <\/h2>\n\n\n\n

Currently, most graphics cards will come equipped with both ports to allow for maximum flexibility, granting you the freedom of choice. The latest NVIDIA, AMD, and Intel graphics cards are equipped with both HDMI and DisplayPort, using a mix of the commonly used standards. This grants you flexible options when connecting to your gaming monitor or television. <\/p>\n<\/div>\n\n\n\n

Refresh Rates and Resolution<\/h2>\n\n\n\n

The next things to consider are refresh rates and resolutions. Both are vitally important for making your gaming buttery smooth. But what are they? Refresh rate<\/strong> refers to the number of images displayed per second on your screen, whereas the resolution<\/strong> <\/em><\/strong>is how many pixels are on the screen. When it comes to refresh rates, the sweet spot for gaming tends to be around 144Hz, although 240Hz is becoming popular too. In comparison, your work screen refresh rate will be 60Hz. To get your game as smooth as possible, you will need a monitor, graphics card, and cable that all support the maximum resolution at the highest refresh rate. Otherwise, your game will be juddery and you may have to operate at, *shudders*, lower resolutions. <\/p>\n\n\n\n

When looking at the specs, DisplayPort is the way to go if you are after some hardcore gaming. Working your way through Battlefield 6<\/a> on a substandard definition is not how we want to play. On the other hand, if you\u2019re using your monitor for more run-of-the-mill tasks, like staring at endless spreadsheets, then an HDMI cable is the better option. <\/p>\n\n\n\n

\"Gaming<\/figure>\n\n\n\n

What about 4K and Ultra HD? <\/h2>\n\n\n\n
\n
\n

Scroll back up to the tables and take from HDMI 1.4 onwards. Yep, 4K is possible from that point on. It\u2019s possible on DisplayPort 1.4, as well. The refresh rates on HDMI are limited, with a maximum of 60Hz. If you are a casual gamer, hitting the farming sims like Stardew Valley<\/a> more often than <\/a>Silent Hill f<\/a>, then HDMI is sufficient. However, if you\u2019re looking for better image transmission at 4K resolutions, then it is DisplayPort all the way. So long as your GPU and monitor support 4K, then DisplayPort is going to have you gaming at amazing resolutions. The way all your cinematic faves were meant to be played!<\/p>\n<\/div>\n\n\n\n

What are AMD FreeSync and Nvidia G-SYNC? <\/h2>\n\n\n\n

AMD FreeSync<\/a> and NVIDIA G-SYNC<\/a> are technologies for synchronising frame rates between graphics cards and monitors. As a result, this vastly improves gameplay as everything is running cohesively, and does not overtax your graphics cards. Ordinarily, monitors do not have a fixed frame rate and thus your graphics card does not always necessarily match what your monitor is showing. It can work too hard or not enough! As a result, your gaming suffers. Images tear or shatter, stuttering occurs, and a bad time is had all round. FreeSync and G-Sync eliminate this. Both of these technologies are supported by HDMI and DisplayPort. <\/p>\n\n\n\n

Multiple Monitor Set-Ups <\/h2>\n\n\n\n

In the specification table, I mention \u201cmulti-stream\u201d which is referring to the cable\u2019s ability to daisy chain monitors in sequence. This can only be achieved with DisplayPort and means that not every monitor needs to be directly plugged into your graphics card, unlike with HDMI. One connection is sufficient and able to be continued from one monitor to the next. Cable management is much easier and you get amazing connectivity on all your monitors. That is *chefs kiss* indeed! <\/p>\n\n\n\n
