DisplayPort 2.1 vs 1.4

I use the 2.1 cable in my current setup and have previously used the 1.4 cable, I will earn a small commission from these links at no extra cost to you!

DisplayPort 2.1 launched in 2022 and is the latest version of the DisplayPort interface standard, while DisplayPort 1.4 launched in 2016 is the most commonly used previous version. They differ in several aspects, including bandwidth, resolution, refresh rate, and features. In this video were going to look at what separates them and whether it's a big upgrade.

One of the main differences between DisplayPort 2.1 and 1.4 is their bandwidth. DisplayPort 2.1 offers a higher maximum bandwidth of 77.4 Gbps compared to DisplayPort 1.4's maximum bandwidth of 32.4 Gbps. This allows DisplayPort 2.1 to support higher resolutions, refresh rates, and colour depths.

Another difference is their maximum resolution and refresh rate. DisplayPort 2.1 can support up to 8K resolution (7680 x 4320 pixels) at 60 Hz or 4K resolution at 144 Hz. DisplayPort 1.4, on the other hand, can support up to 8K resolution at 30 Hz or 4K resolution at 120 Hz. This means that DisplayPort 2.1 can handle higher-resolution displays and smoother gameplay than DisplayPort 1.4.

Finally, DisplayPort 2.1 also supports Multi-Stream Transport (MST) and HBR3, which allow for multiple displays to be daisy-chained together and for high-bandwidth audio and video signals to be transmitted simultaneously over a single cable. These features are not available in DisplayPort 1.4.
In conclusion, DisplayPort 2.1 is a significant improvement over DisplayPort 1.4 in terms of bandwidth, resolution, refresh rate, and features. It is capable of supporting higher-resolution displays, smoother gameplay, and more advanced features than DisplayPort 1.4, making it a better choice for high-end displays and gaming setups.

Do you use the latest version of display port?

Do you use the latest version of DisplayPort and what increase in performance have you seen?

[dabiri]

An extra 24hz at 4k! Wow! I need that!

[soulsolis]

You're a life saver, recently got myself a 4k 144hz display that Sadly goes black screen a few seconds often every time I use an OpenGL Application, only to realize my version was not made to tolerate high color depth. Thank you ❤️

As of this writing Dell is offering Display Port 1.4. As with TV's, the higher you go on resolution the less you will be able to utilize it. Standard broadcast signals DO NOT support higher resolution so spending the money on fancy graphics is a waste because you'll never see those higher resolutions. Unless your into gaming and money is not the object your eyes will hardly see the difference. Some may argue they can, but the ability to receive super high resolution is limited by device and signal. Be happy with a lesser standard until a higher standard is adopted mainstream.

I just bought me an Aorus FO32U2P, just because of DP 2.1. This monitor will last for the next 10 years.

I have 1.2 dp but i use HDMI 1.4 couse i hve fansy cable for it. While for dp i was not able to find nice cable.

Can display port 2.1 get 240 hz at 1440p?

[TEJASPLAYZ]

hey bro my laptop has a usb 3.2 gen 2 type c port and its max transfer speed is 10gbps and its supports dp 1.4 how is this possible on 3.2 gen 2 type c port how will it transfer 32 gbps on a 10 gbps port wtf plz tell me

[duckx]

Will I be able to get over 240 fps at 1080p on 1.4 or 2.1?

[smokinghazards]

Hi, thanks for the video. Could you please answer whether we can connect newer version display port cable to 1.4 version?

[bumperxx]

hey guess what DPort VESA announced version 2.1a of the DisplayPort standard on 8 January 2024.

I have a monitor with displayport 1.4, can i connect a 7900xtx? That gpu have 2.1 displayport 😐

[BENNYLiiGHT]

There is one question im asking myself now...

If my graphics card + monitor both use display port 1.4

But I want to use / I use a display port 2.0 cable, does it still work?
Or whether the graphics card or monitor, one of them has to be display port 2.0 to work with "downwards compatibility" ?

[whoshotya]

What I dont get is that I have the new 1440p 360hz oled from alienware but it only has DP 1.4 🤔 I have a 2.1 cable connected to it though and Im just hoping it's working 🤷‍♂️ It feels smooth but Im starting to wonder if it could be smoother.

[TwinkSlayer]

just wondering if have a 1080p 180hz monitor, i see that display port helps support higher resolutions but will it help with more consistent framerate/image while still on running on a 1080p monitor?

[ParanolMyWay]

for full hd resolution, I need version 2.0, or I can get full functionality with version 1.4?

[iambnkrs]

If i have a gpu with dp2.1 and a 240hz 1440p monitor at dp1.4, will this lead to issues?

[agnyphyo]

Hi mate! My GPU is DP 2.1 and my monitor is DP 1.4 with 2K 180Hz. To utilize better experience in games, what type cable and brand shall I use better?

[interstellar]

My monitor supports DP 1.2 and my GPU supports 1.4a, can I still use this type of cable is it like retroactive?

[RIP_Lithium]

i have a 280hz monitor but recently it went black one day and when it started working again it only caps at 144hz (i used to have it at 240) i would use a display port for it but im not sure what type it was do I need to get a new displayport or do you have an idea on what the problem might be?
