Should you wait for the iPhone Fold or Galaxy Z Fold 8 in 2026? Neither an Apple foldable iPhone nor a Samsung Galaxy Z Fold 8 has been announced or verified by official manufacturer datasheets as of October 2026. Instead of waiting on unverified supply-chain rumors for mobile multitasking, pair your current USB-C DisplayPort Alt Mode phone or laptop with the ASUS ZenScreen MB16AHG (15.6-inch 144 Hz portable monitor) and CalDigit TS4 dock for three times the screen area today.

How we evaluated foldable rumors and shipping portable display alternatives
Because The Hardware Pick only recommends hardware backed by verifiable manufacturer datasheets and independent third-party measurements (RTINGS and Monitors Unboxed), we never treat leaked supply-chain renders as confirmed product specs. We evaluated shipping USB-C portable monitors and docking stations against the core problem foldable buyers want to solve: portable multitasking and desktop convergence.
- Usable workspace area: Even an 8-inch square foldable inner screen offers less than one-third the surface area of a 15.6-inch 16:9 portable display like the ASUS ZenScreen MB16AHG and struggles with side-by-side 16:9 windows.
- USB-C DisplayPort Alt Mode compatibility: Modern flagship USB-C iPhones (iPhone 15 Pro and newer), Samsung Galaxy S/Fold devices (with Samsung DeX), and laptops output native video over a single USB-C cable.
- Power pass-through & dock expansion: Portable monitors draw power from your phone or laptop battery unless connected to external USB-C power delivery or a powered hub like the CalDigit TS4.
- What we ruled out and honest cons: We ruled out unverified foldable spec tables and off-brand portable displays that lack certified DisplayPort Alt Mode controllers. Honest cons of portable monitors: carrying a separate 15.6-inch slate requires a backpack sleeve, and running the MB16AHG at 144 Hz requires an external USB-C wall adapter for full brightness.
Why do 15.6-inch USB-C portable monitors beat foldable screens for real work?
A 15.6-inch 16:9 portable monitor like the ASUS ZenScreen MB16AHG provides more than triple the surface area of a book-style foldable phone, sits at eye level on an integrated fold-out kickstand, and works across your phone, work laptop, and gaming handheld without locking you into a fragile plastic crease.
When paired with a compact Bluetooth keyboard and mouse, connecting a Samsung DeX phone or USB-C laptop to a 15.6-inch 144 Hz display gives you full desktop window management that no pocketable screen can match.
Frequently asked questions
Has Apple or Samsung officially announced an iPhone Fold or Galaxy Z Fold 8?
No, as of October 2026 neither Apple nor Samsung has published official hardware specifications, release dates, or press datasheets for an iPhone Fold (or iPhone Duo) or Galaxy Z Fold 8. Any circulating specifications are unverified supply-chain rumors and should not guide hardware purchasing decisions today.
Can you connect an ASUS ZenScreen portable monitor directly to a USB-C phone?
Yes, if your smartphone supports USB-C DisplayPort Alternate Mode (including USB-C iPhone Pro models and Samsung Galaxy S and Z series phones with DeX), you can connect directly to the ASUS ZenScreen MB16AHG over USB-C. Connect a USB-C charger to the monitor’s second port so the screen does not drain your phone battery.
Should you choose the CalDigit TS4 or Anker 575 dock for a single-cable desk?
Choose the CalDigit TS4 if your laptop or tablet supports Thunderbolt 4 or USB4 and you want 98W charging, 2.5GbE Ethernet, and high-refresh 1440p or dual 4K display bandwidth. Choose the Anker 575 13-in-1 dock if you only need 85W charging, 60 Hz HDMI/DisplayPort outputs, and Gigabit Ethernet.
