Know The Best Cable For Your 4K Monitor

At present, a 4K monitor comes with lots of cable ports on its back. The buyer of a new 4K monitor many times gets confused after seeing the bundle of cable ports. The Display port, USB-C, Thunderbolt, HDMI are included in a ports list of a new 4K monitor. It is really very important to know which is the best port for use among all the ports. That’s why to acknowledge you, I made this article thus you can know the important information very easily related to the subject.

Start Exploring Information About Cable For 4K Monitor

A. The All-Rounder HDMI 2.1

This is a popular one display interface, used in Bluray players and in television also to connect games consoles. The High Definition Multimedia Interface (HDMI) is capable to drive a 10K display at 60 frames/second in full 10-bit color, HDMI supports a throughput of 48 Gbps, and HDMI 2.1 is fairer at this propose.

The HDMI 2.1 use the FreeSync (or VESA AdaptiveSync) for eliminating screen-tearing. HDMI 2.1 is capable of providing the ability of uncommon limited power delivery, and this can also work as an Ethernet adapter (with the right cable). Interestingly, connecting a computer to a monitor and then cable connecting that 4K monitor to another 4K monitor is achievable via HDMI 2.1.Types of HDMI Ports

Though HDMI 2.1 is more efficient there is a big chance on your 4K monitor can only support the older HDMI 2.0 standard, which reveals that the 4K monitor is limited to outputting a 4K signal at 60 frames / second in 8-bit color. Not only that, but this will be also limited to 44.1 kHz and 16-bit pass-through audio with only two uncompressed audio channels. A monitor with the supportive capacity of HDMI 2.1 is really very rare.

The HDMI 2.0 can not support the FreeSync standard, their HDR content is limited to static metadata compared to HDMI 2.1, the HDR 10 is standard. The HDMI 2.1 offers dynamic metadata including HDR10+ and Dolby Vision. Actually a 4K monitor with HDMI 2.1 is an outstanding combination, but if your monitor only supports HDMI 2.0 the DisplayPort will be an effective helpful and featureful way for you.

[Throughput means, a measurement of how many units of information a system can process between a given amount of time.]

To know information about DisplayPort you have to see the 4th paragraph.

B. Perfect for Laptop Owners USB-C

Almost in all modern laptops, the USB-C ports are situated. The capability of carrying a display signal over USB-C depends on a technology that knows as USB-C Alt Mode, the essential part is, this is just DisplayPort through a USB-C plug, and the raw throughput and supported resolution vary on the DisplayPort. The USB-C Alt Mode display output supports the ability to provide USB Power Delivery (USB-PD), so who’s laptop supports USB-PD they can charge their laptop with a single cable and output to a monitor.

Actually, all the technical aspects of USB-C DisplayPort over Alt Mode mirror both regular DisplayPort 1.4 and that might possible to get a 4K signal at 60 frames/ 8-bit color via 8K resolutions in 10-bit. Daisy-chaining multiple 4K monitor connections over USB-C is achievable.Display port to USB-C Port

If your laptop supports display output over USB-C Alt Mode then you can get some features that I mentioned in the above stanzas, another feature of USB-C (if your laptop is usable with this) is, when you move around the house/workplace, again and again, the USB-PD can help you lot, there you would not be required to bring a charger with you for plug into a monitor.

To know that your monitor provides the right power output or not for your laptop, you have to do some analysis on this matter. The Dell UltraSharp U3219Q offers USB-C connectivity with 90 W of USB-PD, which is more than enough to charge a MacBook Air or a Dell XPS 13 laptop.

After reading all these conditions, and features if you think this will be helpful for you then you can choose that, or if not then you can see the capacity and features of Thunderbolt, which mentioned at just below.

C. Important for Daisy-Changing and Macs, The Thunderbolt

This is an active technology, Thunderbolt 3 cable supports up to 40 Gbps throughput. Basically, Thunderbolt also uses the USB-C port, but both are not similar. A passive technology which offers up to 20 Gbps, is the USB 3.2 Gen 2. Though these two technologies use the same USB-C port, they are not interchangeable.Thunderbolt port

There are some features that we see in Thunderbolt 3, only one Thunderbolt cable might run two 4K displays (at 60 frames), a single 5K display (at 60 frames), or a single 4K display (at 120 frames). That also allows you to daisy-chain other displays, other devices like as, external GPU enclosures, docks, or external storage arrays.

If you want to use Thunderbolt 3 to connect your display you would have to buy a Thunderbolt 3- capable monitor. That might cost more than your average HDMI or DisplayPort 4K monitors. Two Thunderbolt cables can drive four daisy-chained 4K display or two 5Ks, on a 2019 16-inch MacBook Pro.

Think, if all the capabilities and terms you got then Thunderbolt will be worthy for you.

D. The Strong and Fast DisplayPort

The DisplayPort 1.4 supports 8K resolution at 60 frames in true 10-bit color with only display stream compression. The DisplayPort 1.4 offers dynamic metadata for HDR content ( Dolby Vision and HDR10+) and provide color gamut and wider brightness (your monitor’s capability is also important for this), this also able to support 192 kHz and 24-bit sound with 7.1 channels of uncompressed audio.

The uncompressed performance seems similar in DisplayPort 1.4 as HDMI 2.0, which is at 4K/ 60/ 8-bit. If your monitor support, you can connect up to two displays via daisy-changing at 4K resolution.  DisplayPort has the absence of Ethernet support, naturally, DisplayPort is the most used way of connection for Computer-to-monitor. HDMI offers some applications such as connecting AV receivers, TVs, and other consumer electronic devices which are not seen in DisplayPort.DisplayPort 8K

The DisplayPort 2.1 when it comes in the future, might provide 4K frame rates of higher than 60 frames in true 10-bit color, but this would possibly usable on one monitor.

Overall, we can say that the DisplayPort supports lots of featureful advantages over HDMI 2.0 though they mostly apply if you want to daisy-chain multiple monitors.


The best option really varies on your requirement, that means what you want. For example, if you see at all the variants, there the first, HDMI 2.1 able to provide the greatest throughput in terms of maximum resolution, color depth, and frame rate. That is now in the market and it is really amazing in the sense of throughput.

Secondly, the USB-C base on either your laptop supports USB-C Alt Mode with DisplayPort, and similarly, the USB-C also depends on the monitor delivers enough power to charge your laptop. So, if your laptop supports both conditions then USB-C will be helpful for you.

Next, the Thunderbolt 3,  featureful especially for some reasons, daisy-changing two 4K monitors or connecting a 5K display, the fastest connection with the highest data throughput, and this allow connecting other devices. Here, you will be required to support a costly cable or both the monitor and computer side.

Finally, DisplayPort 1.4 is advantageous to HDMI 2.0 appropriate to its superior throughput and daisy-changing abilities, as a result, if you are not run on multiple monitors, it can match two efficiently.

So, I think now you are able to easily choose which is the perfect port for you, let’s choose and use that……..
