A portable monitor gives you a second screen without the bulk of a desktop — plug it into your laptop via a single USB-C cable and you’re working, gaming, or watching content on the go. In South Africa, where remote work and hybrid setups are common, a quality portable monitor can be a game-changer if you pick the right size and connectivity for your needs.
This guide covers what matters when choosing a portable monitor in 2026, with local prices and availability in mind.
Key Takeaways
- 15.6–17.3 inches is the sweet spot for most users — big enough to be useful, small enough to fit in a bag.
- USB-C with power delivery is the modern standard — one cable for video, data, and charging.
- Look for FHD (1920×1080) resolution at this size — anything less looks pixelated on a close screen.
- A matte anti-glare coating beats glossy for outdoor or variable-light use, which matters during loadshedding.
- Budget R800–R2,500 for a decent entry-level portable monitor in South Africa.
What Size Portable Monitor Should You Choose?
Portable monitors typically range from 13.3 to 17.3 inches. Here’s how they compare:

| Size | Best for | Portability | Price range (ZAR) |
|---|---|---|---|
| 13.3″ – 14″ | Travel, ultrabook users | Fits in most laptop bags | R800 – R1,500 |
| 15.6″ – 16″ | Most users, general work | Fits in large bags or carry-on | R1,000 – R2,000 |
| 17.3″ – 17.3″ | Desktop replacement, gaming | Needs dedicated case | R1,500 – R2,500 |
For most people, a 15.6″ or 16″ model hits the sweet spot — large enough for productivity, compact enough to actually carry.
Connectivity: USB-C vs HDMI
How you connect the portable monitor matters more than size. Two main options exist:

USB-C (preferred)
Modern USB-C ports can carry video, data, and power over a single cable. If your laptop has a USB-C port with DisplayPort Alt Mode, you only need one cable for everything:
- Video signal from the laptop to the monitor.
- Power to charge your laptop (if the monitor supports USB-PD passthrough).
- USB connectivity for built-in speakers or webcam (if present).
HDMI (legacy)
If your laptop only has HDMI or no USB-C port, you’ll need a USB-C to HDMI adapter or a direct HDMI cable. This works fine but uses two cables and doesn’t charge your laptop.
USB-C is the clear winner if your devices support it. HDMI is still common and perfectly functional for older laptops or budget setups.
When Do You Need a Portable Monitor?
A portable monitor isn’t for everyone. Here’s when it makes sense:
- Remote work from home: A second screen lets you keep email on one display and your work app on the other — no more alt-tabbing.
- Travel and café work: Fits in your bag, sets up anywhere with a power outlet.
- Loadshedding resilience: During power cuts, a laptop on battery plus a portable monitor (powered from USB-C) can keep you productive longer than a desktop.
- Gaming on the go: Connect to a Nintendo Switch, Steam Deck, or console — no need for a TV.
- Field work: Consultants, journalists, and surveyors who need extra screen space outside the office.

Common Mistakes to Avoid
Buying a glossy screen for outdoor use
Glossy screens look great indoors but reflect light like mirrors outside. For outdoor or variable-light use, choose a matte anti-glare finish.
Ignoring the stand and cover
Some portable monitors come with a built-in smart cover that doubles as a stand. Others require a separate case or tripod mount. Check what’s included — buying accessories separately adds to the cost.
Picking resolution too low
A 15.6″ screen at 1366×768 will look pixelated. Stick to FHD (1920×1080) minimum, ideally IPS panel for better viewing angles and colour accuracy.
Forgetting about refresh rate
If you’re gaming, a 60Hz minimum is essential. Some models offer 120Hz or 144Hz — worth it if gaming is a primary use case, unnecessary for office work.
What Does a Portable Monitor Cost in South Africa?
Prices vary by size, panel quality, and brand. Here’s a rough guide for 2026:
| Category | Price range (ZAR) | Examples |
|---|---|---|
| Budget (14″ – 15.6″, FHD, no extras) | R800 – R1,200 | No-name brands, Takealot generics |
| Mid-range (15.6″ – 16″, FHD, USB-C PD) | R1,200 – R2,000 | ViewSonic, ASUS, POTATOTECH 16″ |
| Premium (17.3″, high refresh, matte finish) | R2,000 – R3,500 | Asus ZenScreen, Dell UltraSharp portable |
Check Takealot, Incredible Connection, and local computer shops for current pricing. Prices tend to drop during Black Friday and back-to-school sales.
Frequently Asked Questions
Can a portable monitor replace my desktop monitor?
For light work and travel, yes. For professional colour work or gaming, a larger desktop monitor is still better. A portable monitor is best as a secondary screen — not a full desktop replacement.
Does a portable monitor work with my laptop?
If your laptop has a USB-C port that supports video output (DisplayPort Alt Mode), it will work. Most modern laptops do. If your laptop only has HDMI, you’ll need an adapter or a direct HDMI cable.
Can I use a portable monitor while travelling?
Yes — most portable monitors are under 1kg and fit in a laptop bag. They work with USB bus power, so no separate power adapter needed. Just ensure your device has the right ports.
Is a portable monitor good for gaming?
For casual gaming (Switch, Steam Deck, mobile games), yes. For competitive PC gaming, a desktop monitor with higher refresh rates and faster response times is better.
Do I need a specific cable for USB-C connection?
Use a USB-C to USB-C cable that supports video output. Not all USB-C cables carry video — check the cable spec or use the one that came with your monitor.
