ASUS ZenScreen MB165B 15.6" Portable USB Monitor
PRODUCT DESCRIPTION
ASUS ZenScreen MB165B 15.6" Portable USB Monitor (ASU-MB165B) / (90LM0703-B01110) - 3 Years Local Warranty
An Affordable, Narrow-Bezel Second Screen Powered by a Single USB Cable
The ASUS ZenScreen MB165B is a 15.6-inch HD (1366 x 768) portable monitor built as a straightforward, budget-friendly second screen. It runs entirely off a single USB 3.2 cable for both power and video signal — no separate power brick, no HDMI lead, just one cable to a compatible laptop's USB port. For a Singapore office worker or student who mainly needs extra screen real estate for documents, browser tabs and chat windows rather than colour-critical work, it is a low-cost way to add a display without carrying extra hardware.
Slim, Narrow-Bezel Build for Everyday Carry
At approximately 780 g and 11.8 mm thick, the MB165B is light enough to slide into the same sleeve as a laptop. The narrow-bezel design keeps the footprint compact relative to the 15.6-inch screen, and the monitor folds into its own ASUS ZenScreen sleeve, which also doubles as a kickstand.
USB-Powered Simplicity — No Driver Hunting on Most Systems
Because both power and video ride on the single USB 3.2 connection, setup on a compatible Windows laptop is largely plug-and-play. A rear 1/4"-threaded tripod socket adds mounting flexibility beyond the fold-out sleeve stand, and with ASUS DisplayWidget software installed, the screen automatically senses rotation and switches between landscape and portrait.
Where This Model Makes Sense — and Where It Does Not
The MB165B uses a TN panel at HD resolution (1366 x 768), not the IPS Full HD panel found on the step-up ZenScreen MB166C or MB166CR. It suits document work, spreadsheets, email and general multitasking well. For photo editing, colour-sensitive work, or a sharper Full HD image, the MB166C or MB166CR in our catalogue are the better fit.
Supplied Locally, with GST Invoice and Singapore Warranty
SourceIT supplies the ASUS ZenScreen MB165B with a full GST invoice and local Singapore warranty support. ASUS's manufacturer term for this model is 3 years.

Compatibility & Connectivity
What It Connects To
The MB165B connects over a single USB 3.2 cable that carries both the video signal and the monitor's power draw. This differs from the USB-C DisplayPort Alt Mode used on the step-up MB166C and MB166CR — check that your laptop's driver/software stack supports USB-signal displays (typically via ASUS DisplayWidget or a DisplayLink-based driver) before relying on it as a primary second screen for a non-Windows or unusual device; email us your laptop model if you are unsure.
Power Draw
Typical power consumption is under 7 W, comfortably within what a laptop's USB 3.2 port can supply alongside the video signal — no separate power adapter is included or required.
Orientation and Mounting
A rear 1/4" tripod socket accepts a standard tripod or compatible monitor arm, in addition to the folding ZenScreen sleeve/stand supplied in the box. With ASUS DisplayWidget software installed, the screen automatically senses rotation and switches between landscape and portrait.

Frequently Asked Questions — ASUS MB165B
Does it need a power adapter?
No. A single USB 3.2 cable carries both the video signal and the monitor's power draw (under 7 W) from the host laptop's USB port.
Is this a Full HD screen?
No — the MB165B is an HD panel at 1366 x 768. If you need Full HD (1920 x 1080), the ZenScreen MB166C or MB166CR in our catalogue use an IPS Full HD panel over USB-C instead.
Will it work with my laptop straight away?
Most Windows laptops with a compatible USB port and the ASUS DisplayWidget driver installed will run it without extra hardware. If you are on macOS or an older machine, email us your laptop model and we will confirm compatibility before you order.
Can it run in portrait mode?
Yes, with ASUS DisplayWidget software installed on the connected laptop, the screen automatically senses rotation and switches between landscape and portrait.
Does it have built-in speakers?
No. The MB165B has no built-in speaker.
What is in the box?
The monitor, a folding ZenScreen sleeve that doubles as a stand, a USB 3.2 cable, a warranty card and a quick start guide.
How does it compare with the ZenScreen MB166C?
The MB166C steps up to a Full HD IPS panel over USB-C (DisplayPort Alt Mode) with TÜV-certified Flicker-free and Low Blue Light filtering. The MB165B is the more affordable HD/TN option running over standard USB, better suited to everyday document and browser work than colour-sensitive tasks.
Does it come with a Singapore warranty and a GST invoice?
Yes. Every ASUS ZenScreen MB165B sold by SourceIT comes with local Singapore warranty and a GST invoice; ASUS backs the MB165B with a 3-year manufacturer warranty.
