HDMI vs. DisplayPort: Which Connection Should You Use in 2026?
Choosing between HDMI and DisplayPort is not simply a matter of selecting the connector with the largest version number.
The right connection depends on four things:
- The video output supported by your PC or Mini PC
- The input supported by your monitor or TV
- The resolution, refresh rate and colour format you want
- Whether you need features such as VRR, HDR, eARC or multiple monitors
This guide compares HDMI and DisplayPort for gaming, office work, TVs, high-refresh-rate monitors and Mini PCs.
HDMI vs. DisplayPort: The Short Answer
Use HDMI for TVs, game consoles, soundbars and home-entertainment systems.
Use DisplayPort for PC monitors, high-refresh-rate gaming and flexible multi-monitor setups—provided that both devices support the required DisplayPort mode.
For a Mini PC connected to a 4K 60Hz television, HDMI 2.0 is normally sufficient. For a 4K 120Hz gaming monitor or a multi-monitor workstation, DisplayPort 1.4, DisplayPort 2.x or USB-C with DisplayPort Alt Mode may offer more flexibility.
Neither connector automatically produces better image quality. At the same resolution, refresh rate, colour depth and chroma format, a stable HDMI and DisplayPort connection should deliver the same digital image.

The latest standard is not necessarily the standard implemented by the device. Always check the specifications of the actual Mini PC, GPU, monitor and cable.
What Is HDMI?
HDMI stands for High-Definition Multimedia Interface. It carries digital video and audio through one cable and is the dominant connection on televisions, game consoles, soundbars, AV receivers and projectors.
Its biggest practical advantages are broad television compatibility and support for home-entertainment features such as:
- Consumer Electronics Control, or CEC
- Audio Return Channel, or ARC
- Enhanced Audio Return Channel, or eARC
- Variable Refresh Rate, or VRR
- Auto Low Latency Mode, or ALLM
HDMI 2.2 was officially released in June 2025. It increases the maximum bandwidth to 96 Gbps and introduces the Ultra96 HDMI Cable designation. It also adds the Latency Indication Protocol, or LIP, to improve audio and video synchronisation in complex systems.
However, an HDMI version number alone does not guarantee that every optional feature or the maximum bandwidth is available. Device manufacturers must state the supported features and bandwidth clearly.
What Is DisplayPort?
DisplayPort is a digital display interface developed by VESA. It is mainly used on desktop graphics cards, PC monitors, professional displays, docking stations and Mini PCs.
Its practical strengths include:
- High-resolution and high-refresh-rate monitor support
- Adaptive-Sync
- Multi-Stream Transport, or MST
- Display Stream Compression, or DSC
- DisplayPort Alt Mode over USB-C
- Flexible multi-monitor configurations
The current standard is DisplayPort 2.1b. At the highest UHBR20 data rate, DisplayPort provides 80 Gbps of raw bandwidth and approximately 77.37 Gbps of payload bandwidth.
DisplayPort 2.1b also introduces support for longer DP80LL active cables, reaching up to three metres under the relevant certification.
A device labelled “DisplayPort 2.1” or “2.1b” does not necessarily support UHBR20. VESA permits lower link rates in compliant implementations, so the supported UHBR mode must be checked separately. DisplayPort official FAQ.
HDMI and DisplayPort Version Comparison
| Standard | Maximum raw bandwidth | Typical capability or use |
|---|---|---|
| HDMI 2.0 | 18 Gbps | Commonly used for 4K at 60Hz |
| HDMI 2.1 | Up to 48 Gbps | 4K 120Hz and 8K modes on compatible devices |
| HDMI 2.2 | Up to 96 Gbps | Future high-resolution and high-refresh-rate displays |
| DisplayPort 1.4 | 32.4 Gbps | High-refresh 1440p and 4K; higher modes with DSC |
| DisplayPort 2.1b UHBR20 | 80 Gbps | High-resolution, high-refresh and multi-display applications |
These maximum figures are not directly equivalent because HDMI and DisplayPort use different encoding systems. Resolution support also depends on colour depth, chroma format, HDR and whether DSC is enabled.
For example, the HDMI Forum lists uncompressed 4K at 240Hz and 8K at 60Hz with 4:4:4 chroma among the formats supported by the full HDMI 2.2 specification. That does not mean every HDMI 2.2 device supports every one of these modes.
Is HDMI or DisplayPort Better for Image Quality?
Neither has inherently better image quality.
If both connections output:
- The same resolution
- The same refresh rate
- The same colour depth
- The same RGB or chroma format
- The same HDR signal
…the visible image should be equivalent.
Apparent quality differences usually occur because one connection has fallen back to a different setting. For example, one port may use 4:4:4 colour while another uses chroma subsampling, or one may support 10-bit HDR only at a lower refresh rate.
If text looks blurred after changing cables, check the output resolution, scaling, RGB range, colour format and chroma mode before assuming the cable type is responsible.
Is DisplayPort or HDMI Better for Gaming?
For a gaming PC and gaming monitor, DisplayPort is often the more practical choice. It is widely available on graphics cards and high-refresh-rate monitors, and it supports Adaptive-Sync on compatible hardware.
HDMI is usually the better choice for console gaming and gaming on a television. Modern TVs frequently reserve their advanced gaming features—such as 4K 120Hz, VRR and ALLM—for specific HDMI ports.
The correct answer depends on the actual ports:
- 1080p or 1440p gaming: Either can work; check the supported refresh rate.
- 4K 60Hz gaming: HDMI 2.0 or DisplayPort 1.2 and later can normally handle it.
- 4K 120Hz gaming: Check the exact HDMI, DisplayPort or USB-C output mode on both devices.
- VRR gaming: Confirm compatibility across the GPU, Mini PC, display and connection.
- HDR gaming: Verify resolution, refresh rate, colour depth and HDR simultaneously.
A cable cannot add a refresh rate or VRR mode that the source device does not support.
HDMI or DisplayPort for a 4K 120Hz Monitor?
Do not choose based only on the words “HDMI 2.1” or “DisplayPort 1.4.”
Check the following chain:
Mini PC or GPU output → cable or adapter → monitor input → selected display mode
A 4K 120Hz connection may require:
- Sufficient link bandwidth
- A compatible port on both devices
- The correct cable
- Display Stream Compression in some configurations
- Correct GPU drivers and display settings
If a Mini PC provides DisplayPort 1.4 or USB-C video at 4K 120Hz but only HDMI 2.0 at 4K 60Hz, use DisplayPort or the compatible USB-C video output.
For example, the NIPOGI H2 Mini PC lists HDMI 2.0 output up to 4K 60Hz, while selected configurations provide DisplayPort 1.4 and USB-C video output up to 4K 120Hz. In this case, DisplayPort or USB-C is the more appropriate choice for a compatible 120Hz monitor.
Which Is Better for Multiple Monitors?
DisplayPort generally provides more flexibility for PC multi-monitor setups because it supports Multi-Stream Transport on compatible devices.
MST can allow multiple extended displays through:
- A DisplayPort MST hub
- A compatible daisy-chain monitor
- A USB-C dock using DisplayPort Alt Mode
However, MST support is not guaranteed on every Mini PC, dock or monitor. Available bandwidth is also shared between displays.
Using several independent video outputs is often the simplest solution. A Mini PC with HDMI, DisplayPort and USB-C video can potentially operate three separate monitors without using an HDMI splitter.
An HDMI splitter normally duplicates the same image. It does not automatically create two independent desktops.
For setup instructions, see the NIPOGI three-monitor setup guide.
What About DisplayPort over USB-C?
USB-C describes the connector shape; it does not guarantee video output.
A USB-C port must support one of the following to connect a monitor:
- DisplayPort Alt Mode
- USB4 with display support
- Thunderbolt with display support
Before purchasing a USB-C-to-DisplayPort cable or dock, verify that the Mini PC’s USB-C port explicitly supports video output.
Also check whether using video affects the USB data rate, charging capability or the number of displays supported by the port.
HDMI vs. DisplayPort for Mini PCs
| Mini PC use case | Recommended connection | Reason |
|---|---|---|
| 4K 60Hz television | HDMI 2.0 or later | Broad TV compatibility and audio support |
| Home cinema and soundbar | HDMI with ARC/eARC where supported | Better integration with home-entertainment equipment |
| Office monitor | HDMI or DisplayPort | Use the port that supports the required resolution |
| High-refresh gaming monitor | DisplayPort or capable USB-C output | Often supports higher monitor refresh rates |
| Two or three monitors | Independent HDMI, DP and USB-C outputs | Easier extended-desktop configuration |
| Portable USB-C monitor | USB-C video output | One-cable video and possibly power |
| Legacy DVI monitor | Active or compatible adapter | Adapter limitations must be checked |
NIPOGI connection examples
The NIPOGI H2 Mini PC is suitable for multi-display productivity because it combines HDMI, DisplayPort and USB-C video outputs.
For higher-resolution display configurations, the NIPOGI G1 Mini PC lists HDMI 2.0, DisplayPort 2.0 and USB4 display outputs. Buyers should still match each port’s stated maximum resolution and refresh rate to their monitor.
These examples show why the processor name alone is not enough when choosing a Mini PC. The implemented physical ports and their supported display modes matter just as much.
Does the Cable Matter?
Yes, especially at high resolution and refresh rates.
A poor-quality or unsuitable cable may cause:
- Intermittent black screens
- Flickering
- Signal dropouts
- Reduced refresh rate
- HDR failure
- Visual artefacts
For HDMI 2.1 applications, look for a certified Ultra High Speed HDMI Cable. For full HDMI 2.2 bandwidth, the HDMI Forum has introduced the Ultra96 HDMI Cable designation.
If you plan to use HDMI, read our guide to HDMI cable differences for 4K, 60Hz and 120Hz
to choose the correct certified cable for your Mini PC, monitor or TV.
For DisplayPort, choose a certified cable that matches the required DP40 or DP80 performance class where applicable.
Avoid buying a cable based only on claims such as “8K cable.” Certification and supported bandwidth are more useful than marketing resolution labels.
Can You Convert HDMI to DisplayPort?
Yes, but direction matters.
A DisplayPort-to-HDMI adapter is not necessarily reversible. Converting an HDMI output to a DisplayPort monitor input often requires an active adapter with additional power.
Adapters may also limit:
- Maximum resolution
- Refresh rate
- HDR
- VRR
- Audio
- HDCP compatibility
For high-refresh gaming, use a direct connection whenever possible.
How to Choose: Five Checks Before Buying
Before selecting a cable, monitor or Mini PC, verify:
- Source output: What resolution and refresh rate does the exact port support?
- Display input: Does the monitor support that mode on the chosen input?
- Cable certification: Is the cable certified for the required bandwidth?
- Feature support: Do you need HDR, VRR, eARC, MST or DSC?
- Simultaneous displays: How many independent displays can the Mini PC drive?
This process is more reliable than comparing HDMI and DisplayPort version numbers alone.
Final Verdict
HDMI is generally the best connection for TVs, consoles, soundbars and home-entertainment systems.
DisplayPort is generally the better fit for PC monitors, high-refresh gaming and advanced multi-monitor setups.
For Mini PC buyers, the best port is the one that supports the required resolution and refresh rate on the specific device. HDMI 2.0 can be perfectly adequate for a 4K 60Hz TV, while a 4K 120Hz monitor may require DisplayPort, USB-C video or a higher-bandwidth HDMI implementation.
Always check the supported display mode—not just the connector name.
