HDMI vs DisplayPort
HDMI and DisplayPort both carry digital video and audio, and on modern versions both reach 4K and 8K — so for a single display the picture is effectively the same. Choose by ecosystem and features: HDMI is the standard for TVs, consoles, and home theater (it adds CEC and ARC/eARC), while DisplayPort dominates PC monitors and gaming, with multi-monitor daisy-chaining (MST), more bandwidth headroom, and royalty-free use. A DisplayPort source can drive an HDMI display with an inexpensive passive adapter (DP++).
HDMI (High-Definition Multimedia Interface) arrived in 2002 from the HDMI Founders and is the universal connector on TVs and consoles. DisplayPort followed in 2006 from VESA as a royalty-free standard aimed at computers and high-performance displays. They are not cross-compatible by default the way DVI and HDMI are, but inexpensive adapters bridge them in the common direction.

What is HDMI?
HDMI is the standard interface for consumer audio/video. One cable carries uncompressed digital video and multi-channel digital audio, plus features such as CEC (one-remote control) and ARC/eARC (audio sent back from a TV to a receiver). It is on virtually every TV, streaming box, and game console, which makes it the default for the living room.
What is DisplayPort?
DisplayPort is VESA's royalty-free digital A/V standard, built for computers and high-performance displays. Its standout features are very high bandwidth, broad support for high refresh rates and Adaptive-Sync, and Multi-Stream Transport (MST) for driving several monitors from a single port. It is the connector of choice on graphics cards and PC monitors, and it also travels over USB-C through DisplayPort Alt Mode.
Resolution and bandwidth by standard
Maximum resolution depends on the specific version of each standard:
| Standard | Max bandwidth | Max resolution |
|---|---|---|
| HDMI 1.4 | 10.2 Gbps | 4K @ 30 Hz |
| HDMI 2.0 | 18 Gbps | 4K @ 60 Hz |
| HDMI 2.1 | 48 Gbps | 8K @ 60 Hz / 4K @ 120 Hz |
| DisplayPort 1.2 | 21.6 Gbps | 4K @ 60 Hz |
| DisplayPort 1.4 | 32.4 Gbps | 8K @ 60 Hz / 4K @ 120 Hz (with DSC) |
| DisplayPort 2.1 | 80 Gbps | 16K @ 60 Hz (with DSC) / 4K @ 240 Hz |
Can you connect HDMI to DisplayPort?
Yes, but direction matters:
- DisplayPort source → HDMI display: use an inexpensive passive adapter or cable. This works because almost all DisplayPort outputs support Dual-Mode DisplayPort (DP++), which can output an HDMI signal directly.
- HDMI source → DisplayPort display: requires an active adapter (with a built-in converter chip), because HDMI sources cannot output a DisplayPort signal.
- Match the version for high resolutions. A cheap adapter may cap out at 4K @ 30 Hz; check that the adapter and both devices support the resolution and refresh rate you want.
See the Connector Compatibility Matrix for every pairing, or use the Cable Selector Guide.
Which should you use?
- TV, console, sound bar, or home theater: HDMI — universal support plus CEC and ARC/eARC.
- PC monitor, especially high-refresh or multi-monitor: DisplayPort — more headroom and MST daisy-chaining.
- Laptop or phone over USB-C: DisplayPort Alt Mode is the native path; add a passive adapter for an HDMI TV.
- Mixed devices: a DisplayPort-to-HDMI passive adapter is cheap and reliable; HDMI-to-DisplayPort needs an active adapter.

HDMI vs DisplayPort: frequently asked questions
What is the difference between HDMI and DisplayPort?
Both HDMI and DisplayPort carry digital video and audio over a single cable. HDMI was designed for TVs and home theater and adds consumer features such as CEC and ARC/eARC. DisplayPort was created by VESA for the PC world: it is royalty-free, can daisy-chain multiple monitors from one port (MST), and generally has more bandwidth headroom. For a single display at the same resolution and refresh rate, the picture is effectively identical.
Is DisplayPort better than HDMI?
It depends on the use. DisplayPort is usually the better choice for a PC — higher bandwidth, high refresh rates, and the ability to daisy-chain several monitors from one port. HDMI is the better choice for TVs, consoles, and home theater thanks to universal device support, CEC one-remote control, and ARC/eARC audio return. Neither produces a better picture at the same resolution.
Can I connect DisplayPort to HDMI?
Yes. A DisplayPort source with Dual-Mode DisplayPort (DP++), which is almost universal, drives an HDMI display through an inexpensive passive DisplayPort-to-HDMI adapter or cable. Going the other way — from an HDMI source to a DisplayPort display — requires a more expensive active adapter.
Is HDMI or DisplayPort better for gaming?
DisplayPort has traditionally been preferred for PC gaming because of its high bandwidth and broad support for high refresh rates and Adaptive-Sync (FreeSync/G-Sync). HDMI 2.1 has largely closed the gap with 4K at 120 Hz and VRR, and it is the standard on game consoles. For a high-refresh PC monitor, DisplayPort is the safe pick; for a console on a TV, use HDMI 2.1.
Can DisplayPort run multiple monitors from one port?
Yes. DisplayPort supports Multi-Stream Transport (MST), which lets you daisy-chain two or more monitors from a single DisplayPort output, or split them through an MST hub. HDMI has no equivalent feature, so each HDMI display needs its own port.
Do HDMI and DisplayPort both support 4K and 8K?
Yes. HDMI 2.0 handles 4K at 60 Hz and HDMI 2.1 reaches 8K at 60 Hz or 4K at 120 Hz. DisplayPort 1.4 handles 8K at 60 Hz (with Display Stream Compression), and DisplayPort 2.1 (UHBR) goes far higher. Just make sure both the device and the cable support the version you need.
