ASUS ZenScreen MB14AC 14" Portable USB Monitor
PRODUCT DESCRIPTION
ASUS ZenScreen MB14AC 14" Portable USB Monitor (ASU-MB14AC / 90LM0631-B01110) - 3 Years Local Warranty
The Smallest, Lightest ZenScreen in the Range
The ASUS ZenScreen MB14AC is a 14-inch Full HD (1920 x 1080) IPS portable monitor and the most compact model in the ZenScreen line-up covered here — smaller than the 15.6-inch models, and at under 0.6 kg, noticeably lighter too. For a Singapore student, sales rep or consultant who wants the smallest, lightest second screen that still fits a real laptop bag pocket rather than needing dedicated space, this is the ZenScreen built for minimum bulk.
Hybrid USB-C and USB-A Connectivity
Like the MB16ACV, the MB14AC uses a hybrid signal solution: the USB-C port carries native DisplayPort Alt Mode video and power for hosts that support it, and an included adapter extends compatibility to USB-A hosts via driver — useful for an older laptop without a working USB-C video-out port. A single cable handles both power and display signal in the native USB-C mode.
Full HD Display with Anti-Glare Panel
The IPS panel runs at 1920 x 1080 with a 178°/178° viewing angle, 250 cd/m² typical brightness and a 700:1 contrast ratio, with an anti-glare surface to reduce reflections. ASUS Eye Care — TÜV Rheinland-certified Flicker-Free and Low Blue Light — is active by default.
Ultra-Lightweight at Under 0.6 kg
At approximately 0.59 kg and around 9 mm thick, the MB14AC is meaningfully lighter than the 15.6-inch ZenScreen models, which typically run 0.78–1 kg. A smart cover is included that doubles as a stand, supporting both landscape and portrait orientation, and a 1/4" tripod socket offers an alternative mount.
Auto-Rotation and Low Power Draw
Typical power consumption is rated at around 4.8W, powered directly via USB with no external adapter required for normal use. With ASUS DisplayWidget software installed on the host laptop, the screen auto-detects physical rotation and switches between landscape and portrait.
ASUS SPLENDID Presets and QuickFit
ASUS SPLENDID preset display modes — including Standard, sRGB and Reading profiles — make it quick to switch colour and contrast settings by task, and a QuickFit virtual grid overlays alignment guides for photos, document layouts and spreadsheet columns directly on the screen.
Supplied Locally, with GST Invoice and Singapore Warranty
SourceIT supplies the ASUS ZenScreen MB14AC with a full GST invoice and local Singapore warranty support. ASUS's manufacturer term for this model is 3 years.

Connectivity & Portability
Hybrid Signal — Broader Laptop Compatibility
The USB-C port carries native DisplayPort Alt Mode video and power for hosts that support it, and the included adapter extends compatibility to USB-A hosts via a driver installed on the host laptop — useful for older business laptops still in service without USB-C video output. There is no HDMI port on this model.
The Smallest, Lightest Option in the Range
At approximately 0.59 kg, the MB14AC is meaningfully lighter than any 15.6-inch ZenScreen model, and the 14-inch panel size takes up less desk and bag space. The trade-off is less screen real estate than the larger models — worth weighing against how much you actually value the extra portability day to day.
Smart Cover as Stand
The included smart cover doubles as a stand supporting both landscape and portrait orientation, and the rear 1/4" tripod socket offers an alternative mount for a tripod or compatible monitor arm.
Power Draw
At around 4.8W typical, power consumption is low enough that the monitor runs directly from USB with no external power adapter needed, in either the native USB-C or the USB-A hybrid connection mode.

When the MB14AC Is — and Is Not — the Right Choice
Choose the MB14AC when minimum weight and pocket-size portability are the priority over screen real estate: field sales visits, conference and exhibition use, or a student's daily bag. For desk-bound hybrid work where the monitor mostly stays on one desk, the larger 15.6-inch, 21.5-inch or 23.8-inch ZenScreen models give more working space for a broadly similar price band.

Frequently Asked Questions — ASUS MB14AC
How much smaller and lighter is this than the 15.6-inch ZenScreen models?
At approximately 0.59 kg, the MB14AC is noticeably lighter than the 15.6-inch models, which typically run 0.78–1 kg, and the 14-inch panel takes up less bag and desk space — the trade-off is proportionally less screen real estate.
Will it work with an older laptop that only has USB-A?
Yes, via the included USB-C to USB-A adapter and driver — this is the specific use case the hybrid signal solution is designed for.
Does it need a separate power adapter?
No. It is powered directly via USB at around 4.8W typical, with no external power brick required for normal use.
Does it have an HDMI port?
No. This model has no HDMI input — the hybrid USB-C/USB-A connection is the alternative for non-DP-Alt-Mode hosts.
Can it run in portrait mode?
Yes, using the smart cover as a stand, and with ASUS DisplayWidget software installed the image auto-follows physical rotation.
Does it have built-in speakers?
No built-in speaker on this model.
How does the MB14AC compare with the MB16ACV in your catalogue?
Both use the same hybrid USB-C/USB-A signal solution. The MB14AC is the smaller 14-inch panel at 0.59 kg; the MB16ACV is the larger 15.6-inch panel at around 0.9 kg. Choose based on whether minimum size and weight, or extra screen space, matters more.
Is the 14-inch screen too small for spreadsheet or document work?
It is smaller than a 15.6-inch panel, but still Full HD resolution, so text and layout remain sharp — it suits a second screen for reference material, chat and email more comfortably than dense multi-column spreadsheet work, where the larger ZenScreen models give more room.
Is a driver installation required to use it?
Only for the USB-A hybrid connection path. A native USB-C DisplayPort Alt Mode connection is plug-and-play with no driver needed.
Does it come with a Singapore warranty and a GST invoice?
Yes. Every ASUS ZenScreen MB14AC sold by SourceIT comes with local Singapore warranty and a GST invoice; ASUS backs the MB14AC with a 3-year manufacturer warranty.
