When it comes to LED displays, one of the most important parts of your setup will be the connection type. Its job is to ensure that data and content can be displayed seamlessly, and there’s no overstating its importance.
Now, as far as connections go, it’s almost impossible to find any options more popular than HDMI 2.1 and DisplayPort 1.4. This article compares them so you better know which to choose.
DisplayPort & HDMI Technologies: Understanding Their Peculiarities
Before we go into both concepts, it’s important to understand the technologies that underpin them – HDMI and DisplayPort.
HDMI is a moniker that represents “High-Definition Multimedia Interface.” It is a digital interface that makes it possible for you to transmit both audio and visual content from one device to another. In most cases, it works with television sets – but it can also be useful with DVDs, soundbars, consoles, etc.
With HDMI, you have different versions. And at the moment, the market is especially buzzing over the 2.1 version. The concept uses different connector types, with both audio support and functionality being especially extensive.
On the other hand, you have DisplayPort. It mostly functions in computer displays, although several professional electronics also employ it. There have been several versions coming after 1.4, but for some reason, it appears to be the one that still resonates the most with users. You can access different connectors with DisplayPort, and its support for different audio versions is also notable.
HDMI 2.1 vs DisplayPort 1.4: A Battle Of The Display Connections
Without further ado, let’s get into the major issue – battling these two head-to-head.
HDMI 2.1 vs DisplayPort 1.4: Which Has Higher Bandwidth & Data Rate?
One of the major points that anyone would want to highlight when looking at these two concepts is their bandwidth.
Almost everything that’s bandwidth-related is as optimal as possible on HDMI 2.1. It supports up to 10K video, and its frequency is a mind-boggling 120Hz. Still, that’s not all – it also brings in perks such as high dynamic range (HDR), variable refresh rates, and enhanced audio return channel (eARC), ensuring that what you see is crisp at all times.
Opinions show that this compares rather favorable to DisplayPort 1.4, which offers a top bandwidth of 32.4 Gbps. Its resolution is also mostly capped at 8K, so it might not give you the same level of video support as HDMI 2.1.
In general, this means that HDMI 2.1 delivers a better benchmark overall. Its resolution support is higher, and so is its bandwidth. Of course, this isn’t to say that DisplayPort 1.4 doesn’t do well – its metrics are respectable, and you can still get a lot of value from it., although you might need some compression to work with it as well.
HDMI 2.1 vs DisplayPort 1.4: Looking Out For Better Audio
Another aspect where both concepts tend to be compared a lot has to be in terms of their audio features. And once again, there’s a considerable argument to be made that HDMI 2.1 comes out on top.
For one, HDMI 2.1 offers more audio features – including enhanced audio return channel (eARC), audio formats such as Dolby Atmos, and even 7.1 surround sound. Add this to the fact that it has more audio formats, and it also allows you to control different devices connected to it via a singular remote.
We should also not forget the magic of lip sync correction, which helps HDMI 2.1 ensure that both the audio and video are perfectly synchronized as you watch along.
That said, DisplayPort 1.4 also packs a pretty heavy punch. It offers multi-channel audio with compressed formats like DTS and Dolby, and features like audio integration and adaptive sync also mean that it can be especially good for gamers.
Nevertheless, the use of eARC, broader audio support, and user-friendly features means that anyone who is really serious about improving their sound quality will most likely want to work with HDMI 2.1 as a better option.
HDMI 2.1 vs DisplayPort 1.4: Compatibility & Use Cases
Now, let’s look at what you can do with both concepts and how they can work for you – because, at the end of the day, your decision will depend heavily on the general use cases that you will have for them.
For HDMI 2.1, you have an audio and visual transmitter that has pretty much become the standard for consumer electronics – TV sets, soundbars, gaming consoles, streaming devices, you name it. That said, it also works for PCs and AV receivers, making it a very versatile choice indeed. Everyone – from people looking for better sound at home to those who want to implement professional presentations – can easily make use of HDMI 2.1 to improve the presentation of their content overall.
On the other hand, you have DisplayPort 1.4, which seems to have found a niche amongst computers and PCs. Some manufacturers tout its use in adapters and professional graphics cards, however, meaning that it can provide some use for overall professional gaming setups. With its support for high-resolution displays and multi-monitor setups, DisplayPort 1.4 definitely can be a flexible option too in this regard.
HDMI 2.1 vs DisplayPort 1.4: Pros & Cons Of Each
Pros Of HDMI 2.1
- Quicker Bandwidth: The first and probably most prominent thing that HDMI 2.1 has going for it is that its bandwidth of up to 48 Gbps is much faster than what you get with DisplayPort 1.4.
- Better Audio Features: You can also rest assured of a more packed suite of audio features when you use HDMI 2.1 – from eARC to Dolby Atmos and more.
- Useful Across Devices: These days, pretty much every device has compatibility with HDMI 2.1. So, you won’t have any issues getting it to work.
- Sleek Gaming Functionality: Today’s gaming landscape requires more than just skills – you also need optimal video and sound playback for your gaming. For this, HDMI 2.1 has your back!
- CEC: The Consumer Electronics Control feature ensures you can easily control different devices with one remote – as long as they’re connected to the HDMI itself.
Cons Of HDMI 2.1
- Issues With Cable Length: The fact that you get higher bandwidth also means that the length of your cables will most likely be limited – a major hardware issue.
- The Cost Of Cables: Speaking of cables, you’ll find that getting extra ones can be really pricey.
Pros Of DisplayPort 1.4
- Adaptive Sync Control: With its compatibility with NVIDIA G-Sync and AMD FreeSync, DisplayPort 1.4 is also quite impressive for gaming
- Works With USB-C: To ensure impressive video output, DisplayPort 1.4 works rather well for versatility.
- Cables Run Longer: As you would imagine, this concept also supports longer cable lengths without suffering any issues with signal strength.
Cons Of DisplayPort 1.4
- Not So Many Audio Features: Sadly, DisplayPort 1.4 doesn’t have the advanced audio features that make HDMI 2.1 so coveted.
- You Need An Adapter: In most cases, you’ll need adapters to connect your DisplayPort to inputs like HDMI and VGA for it to really work well.
- Setup Isn’t Easy: Compared to HDMI, you’ll need a few more steps to set up the DisplayPort 1.4 properly.
Conclusion
It’s pretty easy to see why these two connections are the most prominent on the market. Both have revolutionized the display landscape altogether, and their extensive use cases show that.
