MacBook Pro M4 with Thunderbolt 5 and a Portable Monitor
Thunderbolt 5 on the M4 MacBook Pro triples the bandwidth of its predecessor and when paired with the right portable monitor, it unlocks a genuinely powerful dual-screen setup that travels anywhere.
What Thunderbolt 5 actually means for external displays
Previous MacBook Pros used Thunderbolt 4, which tops out at 40 Gb/s of bandwidth. Thunderbolt 5, introduced on the M4 Pro and M4 Max models, jumps to 120 Gb/s (with Bandwidth Boost enabled: up to 240 Gb/s for display data). In plain terms:
- A single TB5 cable can drive a 4K 240 Hz monitor or an 8K display
- Daisy-chaining two high-res monitors over one port is now practical
- Power delivery, data, and video all travel over the same USB-C connector
For portable monitor users, the key takeaway is simple: any USB-C display that previously required a powered hub or separate cable now works perfectly from a single Thunderbolt 5 port, video, power to the display, and charging your Mac at the same time.
Which MacBook Pro M4 models have Thunderbolt 5?
Not every M4 Mac ships with TB5. Here's the breakdown:
- MacBook Pro 14-inch M4 (base): Thunderbolt 4 only
- MacBook Pro 14-inch M4 Pro / M4 Max: Thunderbolt 5 ✓
- MacBook Pro 16-inch M4 Pro / M4 Max: Thunderbolt 5 ✓
If you bought the entry-level 14-inch M4, your ports are TB4. You'll still drive a 4K 60 Hz portable monitor without any issues, you just won't see the higher-refresh benefits of TB5.
Best portable monitors to pair with the M4 MacBook Pro in Dubai
A "portable monitor" typically means a slim panel powered by USB-C, weighing under 1 kg, that you can carry in the same bag as your Mac. Here's what we recommend at different price points (all available in Dubai):
Budget. AED 650–900
- ASUS ZenScreen MB16ACE (16-inch FHD): USB-C powered, 60 Hz, covers sRGB well, light at 0.9 kg. Great for travel-heavy users who need a second screen for docs and email.
- AOC 16T2 (15.6-inch FHD touch): touchscreen, USB-C, slim. Useful for creative workflows that benefit from a touch layer.
Mid-range. AED 900–1,400
- LG 16MQ70 (16-inch IPS, 2560×1600): native 16:10 aspect ratio matches the MacBook Pro screen perfectly. USB-C powered, 60 Hz, 99% sRGB. Our top pick for most users.
- Samsung M7 Portable (27-inch 4K): larger footprint but a full 4K panel at 60 Hz. Powered by USB-C from the Mac.
Premium. AED 1,400–2,000
- ASUS ProArt PA169CDV (15.6-inch 4K touch): 3840×2160 OLED, factory-calibrated, 120 Hz over TB5. The best portable display you can buy right now and TB5 bandwidth makes it shine.
- Dough Spectrum Portable 4K (16-inch): USB-C 4K at up to 120 Hz. Designed explicitly for Thunderbolt, a solid choice if you want the full TB5 bandwidth experience.
Cable matters more than people think
To get Thunderbolt 5 speeds, including 120 Hz at 4K, you need a cable that is certified TB5 or at minimum USB4 Gen 3×2 (40 Gb/s). The cable that ships in the box with most portable monitors is often a basic USB-C cable limited to 10 Gb/s.
Buy a dedicated Thunderbolt 5 cable (look for the TB5 lightning-bolt logo on the connector). A 1m certified TB5 cable costs around AED 120–200 in Dubai. It's worth it - the wrong cable turns a 4K 120 Hz display into a 4K 30 Hz one.
Setup: connecting your portable monitor in Dubai
- Connect the TB5 cable from the MacBook Pro to the display's USB-C input port (not a data-only port).
- The monitor should power on and mirror your Mac's screen immediately.
- Go to System Settings → Displays and choose Use As Separate Display to extend your desktop.
- If the monitor supports higher refresh rates, click ProMotion or select the refresh rate under the display's advanced settings.
- Adjust resolution: for a 4K portable display, "Looks like 2560×1600" or "Looks like 1920×1200" gives crisp HiDPI rendering without making text tiny.
Common issues and fixes
- Display not detected: try a different TB5 port, or disconnect and reconnect. Some displays need a second or two to handshake.
- Only 30 Hz or 60 Hz available when you expected higher: you're almost certainly using a non-TB5 cable. Swap to a certified cable.
- MacBook not charging through the monitor: not all portable displays pass power back. Check the spec sheet, look for "Power Delivery passthrough" or at least 65W PD output.
- Flickering or artifacts: a loose cable connection or an incompatible cable. Reseat the cable; if the issue persists, test with a different certified TB5 cable.

Frequently asked questions
- Only the M4 Pro and M4 Max models have Thunderbolt 5. The base M4 14-inch uses Thunderbolt 4. Check your model in System Settings → General → About.
- Yes. A Thunderbolt 5 port can drive a 4K portable monitor at up to 144 Hz or higher over a single USB-C cable. You need a certified TB5 or USB4 Gen 3 cable, the cable in the monitor box is often not fast enough.
- No. Most modern USB-C portable monitors connect directly via a single Thunderbolt cable, video, power to the display, and Mac charging all over one cable. A dock is only needed if you want to connect additional peripherals at the same time.
- For most users, the LG 16MQ70 (AED 900–1,100) is the best value, 16:10 aspect ratio, 2560×1600, USB-C powered, and matches the MacBook Pro's display proportions exactly. For premium 4K, the ASUS ProArt PA169CDV OLED is the top pick.
