The short version

If your laptop has a USB-C port that supports video output (DisplayPort Alt Mode), use USB-C. One cable does everything — video, power, data. Clean desk, no fuss.

If your laptop doesn't have USB-C video, or you're connecting a game console, use HDMI. You'll need a separate USB cable to power the monitor. Two cables instead of one, but it works with practically every device on the planet.

That's the answer. The rest of this article explains when each option makes sense and the gotchas that catch people off guard.

When USB-C is the obvious choice

Modern MacBooks, most Windows ultrabooks made in the last few years, and many Chromebooks all support USB-C with video output. If you're in this camp, the setup is laughably simple: connect one cable, and the monitor turns on automatically. No power adapter needed.

The convenience is hard to overstate. You set up and pack down in seconds. If you work from multiple locations — a desk one day, a coffee shop the next — the single-cable workflow means one less thing to keep track of.

Some USB-C ports also pass through enough power to charge your laptop while driving the monitor. That varies by device, so check your laptop's spec sheet, but it's a nice bonus when it works.

One important detail, though: not every USB-C port supports video. Some laptops have USB-C ports that are data and charging only. A USB-C port next to the power jack might not be the same as the one on the other side. If you're not sure, check your laptop's manual for the phrase "DisplayPort Alt Mode" — that's the magic words.

When HDMI is the better call

HDMI doesn't carry power. That's the trade-off. But HDMI works with everything.

Older laptops that skipped USB-C video? HDMI. Nintendo Switch? HDMI. Desktop PC with a GPU that doesn't have USB-C? HDMI. Borrowing a friend's laptop and you don't know its specs? HDMI.

The setup is straightforward: HDMI cable for the picture, then connect the monitor's USB power cable to a USB-A port on your laptop or a standard phone charger. Two cables total. It's not the minimalist dream, but it's reliable, and knowing it works across every device is its own kind of peace of mind.

Also worth noting: if you're using a gaming console, HDMI is not just the fallback — it's usually the only option. The Switch dock outputs via HDMI exclusively. PS5 and Xbox Series do have USB-C, but portable monitors typically connect using HDMI for console gaming.

The setup scenarios that actually happen

You have a recent MacBook. Grab the USB-C cable that came with the monitor (or any USB-C cable rated for video) and plug it in. Single cable. Both displays will work immediately. This is the ideal scenario.

You have a Windows laptop from the last 3-4 years. Check if your USB-C port supports DisplayPort Alt Mode. If yes — single cable, same as the MacBook. If no — HDMI + USB power. Works perfectly, just a slightly messier desk.

You have an older laptop with only USB-A ports. HDMI is your path. Make sure you grab any necessary adapters before the monitor arrives, because nothing kills the excitement of a new gadget faster than not having the right cable on day one.

You want to use it with a Switch. HDMI for video. Separate power for the monitor. It's that simple.

Quick compatibility check before you buy

Take thirty seconds to answer these:

1. Does your laptop have a USB-C port with a DisplayPort (DP) icon next to it, or does your spec sheet mention "DisplayPort Alt Mode"? 2. If no — does your laptop have an HDMI port? (Almost all do.) 3. Do you have the right HDMI cable length for your desk setup?

If the answer to #1 is yes, USB-C is your answer. If you answered #2, HDMI. There's no wrong choice — it's just about what your device supports.

And here's the thing people forget: the cable matters too. Not every USB-C cable carries video. Cheap charging cables often don't. Use the cable that came with the monitor. If you need a longer one, buy one explicitly rated for video. A "USB-C charging cable" and a "USB-C video cable" are not the same thing.

FAQ

Can I use both USB-C and HDMI at the same time? Depends on the monitor. Most portable monitors only accept one input at a time. Check the product page for multi-input support.

Why isn't my monitor turning on with a single USB-C cable? Either your laptop's USB-C port doesn't support video output, or the cable you're using isn't rated for video. Try the original cable that came with the monitor first. If that doesn't work, switch to HDMI with separate power.

Can I connect to an iPad or iPhone? iPad Pro and iPad Air models with USB-C support external displays. iPhone 15 and later with USB-C also support it. Older devices with Lightning ports generally don't.

Does HDMI support the touchscreen feature? It varies by monitor. Some portable monitors need a separate USB connection alongside HDMI for touch functionality to work. The VIUSEE Pro 13.5 supports touch over a single USB-C connection — HDMI setups will need to check the product spec.
