USB-C to HDMI vs DisplayPort: Which Adapter Is Right for Your Setup?
Quick Answer
If you're connecting a laptop to a TV or projector, use USB-C to HDMI. If you're connecting to a gaming monitor or need the highest refresh rates, use USB-C to DisplayPort. Both work well — the right choice depends on your display, not your laptop.
Why You Need an Adapter at All
Modern laptops — MacBooks, Dell XPS, Surface, and most ultrabooks — have dropped dedicated HDMI and DisplayPort ports in favour of USB-C and Thunderbolt. An adapter converts your USB-C port to whichever video output your display needs. The good news: USB-C supports both HDMI and DisplayPort via "Alt Mode", so both adapters work from the same port.
USB-C to HDMI: When to Use It
USB-C to HDMI is the right choice when:
- Connecting to a TV — TVs have HDMI ports, not DisplayPort
- Connecting to a projector — most projectors use HDMI
- Connecting to an older monitor that only has HDMI
- Presenting in a meeting room or conference setup — HDMI is the universal standard
- Connecting a PS5 or Xbox to a monitor via adapter (though this is less common)
HDMI adapters are also more universally compatible — virtually every display made in the last decade has an HDMI port.
USB-C to DisplayPort: When to Use It
USB-C to DisplayPort is the better choice when:
- Connecting to a gaming monitor — most high-refresh-rate monitors have DisplayPort
- You need higher refresh rates — DisplayPort 1.4 supports 4K/144Hz; HDMI 2.0 caps at 4K/60Hz
- You use G-Sync or FreeSync — adaptive sync works more reliably over DisplayPort
- You want to daisy chain monitors — DisplayPort supports multi-monitor daisy chaining, HDMI doesn't
- Your monitor is a professional display (colour grading, design work) — DisplayPort is the pro standard
Side-by-Side Comparison
| Factor | USB-C to HDMI | USB-C to DisplayPort |
|---|---|---|
| Best for | TVs, projectors, casual use | Gaming monitors, high refresh rates |
| Max resolution (typical) | 4K @ 60Hz (HDMI 2.0) | 4K @ 144Hz (DP 1.4) |
| Adaptive sync | Limited | G-Sync & FreeSync native |
| Audio support | Yes (including eARC on 2.1) | Yes |
| Display compatibility | Universal (TVs, monitors, projectors) | Monitors and some projectors |
| Daisy chaining | No | Yes |
| Thunderbolt compatible | Yes (with TB adapter) | Yes (with TB adapter) |
Does Your Laptop Support Video Over USB-C?
Not all USB-C ports support video output — only those with DisplayPort Alt Mode or Thunderbolt. Check your laptop's spec sheet or look for a small DisplayPort or Thunderbolt icon next to the USB-C port. If it's there, you're good. If not, that port is data and charging only.
MacBooks with Thunderbolt support both HDMI and DisplayPort adapters. Most modern Windows ultrabooks with USB-C also support Alt Mode, but check your model's specs to be sure.
What About USB-C Hubs and Docks?
If you need both HDMI and DisplayPort outputs, or want to add USB-A ports, Ethernet, and SD card readers at the same time, a USB-C hub or dock is the better solution than individual adapters. A single hub can replace multiple adapters and keep your desk tidy.

Frequently Asked Questions
Can I use USB-C to HDMI for gaming?
Yes, but you'll be limited to 4K/60Hz with a standard HDMI 2.0 adapter. For 4K/120Hz or 144Hz gaming, use a USB-C to HDMI 2.1 adapter or switch to USB-C to DisplayPort.
Does USB-C to DisplayPort work on a MacBook?
Yes — all MacBooks with Thunderbolt 3 or 4 support DisplayPort Alt Mode. A USB-C to DisplayPort cable or adapter works natively, no drivers needed.
Is there a quality difference between USB-C to HDMI and USB-C to DisplayPort?
At 4K/60Hz, both look identical. The difference shows at higher refresh rates (144Hz+) where DisplayPort has the advantage.
Can I connect two monitors with USB-C?
It depends on your laptop. Some Thunderbolt 4 laptops support two external displays. USB-C to DisplayPort with daisy chaining is one option; a Thunderbolt dock is another. Check your laptop's maximum external display count.
What's the difference between a USB-C to HDMI cable and an adapter?
A cable has USB-C on one end and HDMI on the other — cleaner and more reliable. An adapter is a small dongle that converts USB-C to an HDMI port, letting you use a standard HDMI cable. Both work; cables are tidier for permanent setups.
