ASUS ZenScreen MB249C 24" Portable Monitor
PRODUCT DESCRIPTION
ASUS ZenScreen MB249C 23.8" Portable Monitor (ASU-MB249C / 90LM0865-B02110) - 3 Years Local Warranty
The Largest Panel in the ZenScreen Portable Range
The ASUS ZenScreen MB249C is a 23.8-inch Full HD (1920 x 1080) IPS portable monitor — the largest screen size in the ZenScreen line-up, built for hot-desking, training rooms and hybrid workers who want a genuine full-size second monitor that still packs down for transport between locations. For a Singapore office moving toward flexible or shared desking, it answers the question of how to give every desk a large second screen without permanently wiring one in.
At 2.8 kg without the stand and around 7.6 mm thick at its thinnest point, it is noticeably slimmer than a typical fixed desktop monitor of the same size, even though it is the heaviest model in the ZenScreen portable range.
Frameless Design for Multi-Monitor Rows
A frameless bezel design lets two or three MB249C units sit side by side with minimal visual gap between panels — useful where a training room or trading-style desk needs several identical large screens in a row. The anti-glare surface treatment keeps reflections down under office lighting.
75Hz Adaptive-Sync for Smoother Everyday Motion
Refresh rate runs up to 75Hz with Adaptive-Sync support, ahead of the fixed 60Hz that most large portable and desktop monitors are limited to. The practical benefit shows up in scrolling and video playback smoothness rather than in competitive gaming, and Adaptive-Sync reduces the torn horizontal line that appears when the graphics card's frame rate and the monitor's refresh rate fall out of step.
USB-C with 60W Power Delivery — Single-Cable Setup
A single USB-C port carries DisplayPort Alt Mode video and up to 60W of Power Delivery, so one cable handles video and charges a compatible laptop at the same time. That covers most ultrabooks comfortably under typical load; a gaming or workstation laptop drawing heavily may still need its own charger connected in parallel. HDMI 1.4 is also fitted for sources without USB-C video output.
Carrying Handle, C-Clamp Arm and Partition Hook
An integrated carrying handle doubles as a basic kickstand for quick setup, and the box also includes a C-clamp arm and a partition-hook kit, so the MB249C can be clamped to a desk edge or hung on a cubicle divider instead of relying on desk surface. The full stand adjusts for tilt, swivel, pivot and height, and the panel is 100 x 100 mm VESA compatible for a third-party monitor arm.
Built-In Speakers and Eye Care
Built-in stereo speakers (1W x 2) are fitted, and ASUS Eye Care — TÜV Rheinland-certified Flicker-Free and Low Blue Light — is active as standard, both useful for a shared workstation where nobody is going to walk around re-enabling comfort settings on every screen.
Supplied Locally, with GST Invoice and Singapore Warranty
SourceIT supplies the ASUS ZenScreen MB249C with a full GST invoice and local Singapore warranty support. ASUS's manufacturer term for this model is 3 years.

Connectivity & Portability
Single-Cable USB-C Operation
The single USB-C port carries DisplayPort Alt Mode video and up to 60W of Power Delivery, so a compatible laptop can be driven and charged over one cable. Most ultrabooks charge comfortably within 60W under typical office load; a heavier gaming or workstation laptop drawing more than that under sustained load may still need its own charger connected as well. HDMI 1.4 is available for sources without USB-C video output, though HDMI does not carry power.
Mounting Options — Stand, C-Clamp or Partition Hook
The included C-clamp arm lets the MB249C clamp to a desk edge without occupying desk surface, and the partition hook lets it hang on a cubicle divider instead. The bundled stand itself adjusts for tilt, swivel, pivot and height, and the panel is also 100 x 100 mm VESA compatible if you prefer a third-party monitor arm.
Weight and Carrying It Between Locations
At 2.8 kg without the stand, this is the heaviest panel in the ZenScreen portable range, reflecting the larger 23.8-inch screen size — still considerably lighter than a comparable fixed desktop monitor with its own stand and packaging, but heavier than the 15.6-inch and 21.5-inch ZenScreen models. Most deployments travel with the panel and the carrying handle, fitting the C-clamp or partition hook at the destination desk.
Frameless Bezel for Multi-Monitor Rows
The frameless design is specifically useful where two or three MB249C units are set up side by side — a training room, a trading-style desk, or a temporary multi-screen workstation — because the visual gap between adjacent panels is minimal.

Frequently Asked Questions — ASUS MB249C
Is this really "portable" at 23.8 inches?
It is portable in the sense of not needing permanent wiring or a dedicated desk — 2.8 kg with a carrying handle, a C-clamp arm and a partition hook for quick setup and breakdown — but it is heavier than the 15.6-inch and 21.5-inch ZenScreen models, and best thought of as a large flexible-desk monitor rather than a daily laptop-bag companion.
Will a single USB-C cable run and charge my laptop?
Yes, up to 60W of Power Delivery over the same cable that carries video. Most ultrabooks charge comfortably within that; a heavier laptop under sustained load may still need its own charger connected as well.
What mounting options come in the box?
A C-clamp arm for clamping to a desk edge, a partition hook for hanging on a cubicle divider, and the bundled stand itself with tilt, swivel, pivot and height adjustment. The panel is also 100 x 100 mm VESA compatible.
Can I use several of these side by side?
Yes — the frameless bezel design is specifically suited to multi-monitor rows, where two or three units sit close together with minimal visual gap.
Does it have built-in speakers?
Yes — built-in stereo speakers rated at 1 W x 2.
How does the MB249C compare with the smaller MB229CF in your catalogue?
The MB249C is the larger 23.8-inch panel at up to 75Hz with a carrying-handle stand design. The MB229CF is a 21.5-inch panel running up to 100Hz with a more elaborate adjustable stand that also includes a C-clamp and partition hook as standard. Email us your desk size and refresh-rate priority and we will help you choose.
What video inputs does it have besides USB-C?
One HDMI 1.4 input for sources without USB-C DisplayPort Alt Mode video output. HDMI carries video only, not power.
Does it come with a Singapore warranty and a GST invoice?
Yes. Every ASUS ZenScreen MB249C sold by SourceIT comes with local Singapore warranty and a GST invoice; ASUS backs the MB249C with a 3-year manufacturer warranty.
