Quick answer: HDMI, DisplayPort, and USB-C all carry video to a monitor, but each fits a different setup. HDMI is best for consoles and TVs — HDMI 2.1 delivers 4K at 120Hz and it's on every console and television. DisplayPort is best for high-refresh PC gaming, because it exposes the highest refresh rates, supports G-Sync, and can daisy-chain multiple monitors. USB-C and Thunderbolt are best for laptops and MacBooks, since one cable carries video, power, and data at once. For a plain 4K 60Hz office setup, any of the three works fine. Match the port to your device, and check the version number for the bandwidth you actually need.

HDMI, DisplayPort, and USB-C: what's the difference?
All three send a digital video signal to your monitor, but they were designed for different worlds — HDMI for the living room, DisplayPort for the PC, and USB-C for the laptop. HDMI is the universal connector found on TVs, consoles, projectors, and soundbars as well as monitors, with living-room features like audio return and one-remote control. DisplayPort is the PC and gaming standard built into graphics cards, with mandatory support for the features high-refresh gamers need. USB-C is a versatile connector that can carry a DisplayPort video signal while also delivering power and data, which is why it's ideal for laptops. Many monitors include all three, so the real question isn't which is "best" overall, but which suits the device you're plugging in. Our monitor buying guide covers the fundamentals.

HDMI: best for consoles and TVs
HDMI is the universal video connector, and it's the only choice for game consoles and the best one for TVs and home theater. The version matters a lot: HDMI 2.0 carries 18 Gbps for 4K at 60Hz, while HDMI 2.1 jumps to 48 Gbps for 4K at 120Hz plus VRR and Auto Low Latency Mode — essential for a PS5 or Xbox Series X. The newest HDMI 2.2 pushes bandwidth much higher for 8K, but it's still emerging. One catch: HDMI's advanced features are optional, and some ports carry the "2.1" name at reduced bandwidth, so confirm a monitor actually advertises 4K 120Hz and VRR rather than trusting the label. HDMI also uniquely supports eARC for passing high-quality audio to a soundbar. Our PS5 and Xbox monitor guide covers console connections in detail.
DisplayPort: best for high-refresh PC gaming
DisplayPort is the PC gaming standard — it exposes the highest refresh rates, natively supports adaptive sync, and can daisy-chain monitors, which HDMI can't. Graphics cards typically deliver their fastest refresh rates over DisplayPort, and its features aren't optional the way HDMI's are, so it's the more predictable choice for 1440p 240Hz or 4K high-refresh gaming. DisplayPort 1.4 carries 32.4 Gbps — enough for 4K 120Hz, and 4K 144Hz or higher with Display Stream Compression — while DisplayPort 2.1 (UHBR20) reaches 80 Gbps for uncompressed 4K 240Hz, now standard on high-end 2026 GPUs. It's also the only option for daisy-chaining several monitors from one output using MST, and it's required for full G-Sync certification. Our high refresh rate gaming guide and VRR guide go deeper.
USB-C and Thunderbolt: best for laptops
USB-C is ideal for laptops and MacBooks because a single cable carries video, charging power, and data all at once. A USB-C connection uses DisplayPort Alt Mode to send the video signal while Power Delivery charges your laptop and the same cable runs a built-in USB hub — so you dock with one plug instead of three. Thunderbolt uses the same USB-C connector and carries DisplayPort internally, adding more bandwidth and the ability to daisy-chain, which is why MacBooks drive 5K and 6K monitors natively over one cable. The trade-off is that USB-C shares its lanes between video and data, so very high refresh rates can compete with full peripheral speeds. Our Thunderbolt vs USB-C guide and single-cable MacBook guide explain the laptop side.
Versions and bandwidth: which do you need?
The version number sets the bandwidth, and bandwidth determines the resolution and refresh rate you can run — so match the version to your target. Higher bandwidth means you can drive more pixels at a higher refresh without compromising color. Display Stream Compression (DSC) helps both HDMI and DisplayPort exceed their raw limits; it's visually lossless, so modern high-end displays rely on it to hit their top specs. If bandwidth runs short, the system quietly drops to 8-bit color or reduces color detail, so it's worth having headroom.

| Standard | Bandwidth | Typical max |
|---|---|---|
| HDMI 2.0 | 18 Gbps | 4K 60Hz |
| HDMI 2.1 | 48 Gbps | 4K 120Hz |
| DisplayPort 1.4 | 32.4 Gbps | 4K 120Hz (4K 144Hz+ with DSC) |
| DisplayPort 2.1 | Up to 80 Gbps | 4K 240Hz / 8K |
| Thunderbolt 4 | 40 Gbps | 4K 120Hz + power |
Which connection should you use?
Pick by device: HDMI for consoles and TVs, DisplayPort for a gaming PC, and USB-C or Thunderbolt for a laptop. If you game on a PS5 or Xbox, use HDMI 2.1 — consoles don't have DisplayPort at all. If you have a gaming PC and want the highest refresh rate and G-Sync, use DisplayPort. If you connect a MacBook or a modern laptop and want to charge over the same cable, use USB-C or Thunderbolt. For everyday office work at 4K 60Hz, any of the three is fine and you won't see a difference. When a device has several ports, the best one is whichever lets your source and monitor both run at their native spec without an adapter or a bandwidth bottleneck in between.
Does the cable matter?
Yes — use a certified cable that matches your target, and remember that higher bandwidth needs a shorter cable. The certification label matters more than a version number printed on the box, so look for "Ultra High Speed" HDMI or a certified DisplayPort or USB-C cable rated for your resolution and refresh rate; the cable included with a monitor is usually the safest match for its ports. Because high-bandwidth signals degrade over distance, long runs may need an active optical cable, and top DisplayPort 2.1 speeds are often limited to short lengths. Finally, HDMI and DisplayPort use different signaling, so a passive adapter between them can drop VRR or HDR — use the native port on both ends whenever you can. A good cable is cheap insurance for hitting your monitor's full spec.

Quick recommendation
Don't overthink it — choose the connection by what you're plugging in. Console gamers should use HDMI 2.1 for 4K 120Hz and VRR, confirming the monitor truly supports those features. PC gamers chasing high refresh rates should use DisplayPort, which exposes the fastest modes and supports daisy-chaining and G-Sync. MacBook and laptop users get the cleanest setup with USB-C or Thunderbolt, driving the display and charging over a single cable — Kuycon's USB-C models like the G27P deliver up to 100W for exactly that. For plain office work, any port at 4K 60Hz is fine. Whatever you pick, use a certified cable rated for your resolution and refresh rate, keep it as short as practical, and connect natively rather than through an adapter. Match source, cable, and monitor, and you'll get every pixel and frame the panel can deliver.
Frequently asked questions
What is the difference between HDMI and DisplayPort?
HDMI is the universal TV and console connector; DisplayPort is the PC and gaming standard. HDMI appears on TVs, consoles, and home theater gear, with features like audio return. DisplayPort is built into graphics cards, exposes the highest refresh rates, supports multi-monitor daisy-chaining, and has mandatory adaptive sync support. For a gaming PC, DisplayPort is usually preferred; for a console or TV, HDMI is the choice.
Is DisplayPort better than HDMI?
For PC gaming, generally yes; for consoles and TVs, no. DisplayPort offers higher peak bandwidth (80 Gbps on 2.1), native adaptive sync, and daisy-chaining, making it better for high-refresh PC setups. HDMI wins for consoles (the only option), TVs, and home theater thanks to universal compatibility and audio features. Neither is universally better; it depends on your device.
Which is better for gaming, HDMI or DisplayPort?
DisplayPort for a gaming PC, HDMI 2.1 for a console. On PC, DisplayPort usually exposes the highest refresh rates and the most reliable adaptive sync, so it's the safer pick for 1440p 240Hz or 4K high-refresh. On a PS5 or Xbox Series X, there's no DisplayPort, so HDMI 2.1 is required for 4K 120Hz and VRR. Modern HDMI 2.1 on PC is also very capable.
Should I use HDMI or USB-C for my monitor?
Use USB-C if you want to charge a laptop over the same cable; otherwise HDMI is fine. USB-C carries video, power, and data at once, so it's ideal for a MacBook or laptop that can dock with a single cable. HDMI is simpler and universal for desktops, consoles, and TVs. If you don't need charging or single-cable docking, either works for the video itself.
Does USB-C carry video to a monitor?
Yes, when the port supports DisplayPort Alt Mode or Thunderbolt. USB-C isn't automatically a video output — it carries a DisplayPort signal only if the laptop's port supports Alt Mode or Thunderbolt. When it does, one cable can send video, deliver charging power, and run a USB hub. Before buying a USB-C monitor, confirm your laptop's port supports video output and enough charging power.
What is the best connection for a monitor?
The one where your source and monitor both run at their native spec — which depends on the device. HDMI 2.1 is best for consoles and TVs, DisplayPort for high-refresh PC gaming, and USB-C or Thunderbolt for laptops that dock over one cable. For office work at 4K 60Hz, any of them is fine. The best connection is whichever avoids adapters and bandwidth bottlenecks for your setup.
Is HDMI 2.1 or DisplayPort 1.4 better?
HDMI 2.1 has more raw bandwidth, but DisplayPort 1.4 with DSC matches it for most gaming. HDMI 2.1's 48 Gbps beats DisplayPort 1.4's 32.4 Gbps on paper, which helps for uncompressed 4K. But DisplayPort 1.4 with Display Stream Compression reaches 4K 144Hz and beyond, plus better daisy-chaining and adaptive sync. For consoles use HDMI 2.1; for PC high-refresh gaming, DisplayPort 1.4 is the reliable pick.
Can one USB-C cable charge my laptop and display video?
Yes — that's the main advantage of USB-C and Thunderbolt. A single USB-C cable can carry the video signal via DisplayPort Alt Mode while Power Delivery charges your laptop and the cable also runs connected USB devices. This is why USB-C monitors are so convenient for MacBooks and laptops. Just check the monitor supplies enough wattage for your laptop, ideally 65W to 100W.
Which connection is best for 4K 120Hz?
HDMI 2.1 or DisplayPort 1.4 with DSC, depending on your device. For a console, HDMI 2.1 is the only way to get 4K 120Hz. For a PC, either HDMI 2.1 or DisplayPort 1.4 (with Display Stream Compression) can do it, and DisplayPort 2.1 handles it natively with headroom to spare. Make sure your GPU, cable, and monitor all support the mode.
Does the cable matter for a monitor?
Yes — use a certified cable rated for your resolution and refresh rate. A cable that can't carry enough bandwidth will silently limit refresh rate or color. Look for "Ultra High Speed" HDMI or a certified DisplayPort or USB-C cable, prefer the one included with the monitor, and keep it short for high-bandwidth signals. You don't need overpriced cables, just properly certified ones.
Which connection is best for a MacBook?
USB-C or Thunderbolt — MacBooks drive external monitors natively over it. Thunderbolt on a MacBook carries a DisplayPort signal, so a single USB-C cable can run a 5K or 6K display and charge the laptop at the same time. It's the cleanest, most capable option for Mac users. A USB-C monitor with enough Power Delivery wattage lets you dock with just one cable.
Is Thunderbolt the same as USB-C?
No — Thunderbolt uses the USB-C connector but offers more. USB-C is the physical connector; Thunderbolt is a faster protocol that runs over it, carrying DisplayPort internally with higher bandwidth and daisy-chaining support. All Thunderbolt ports are USB-C, but not all USB-C ports are Thunderbolt or even support video, so check your device's capabilities before relying on it.
