Asus adds the ROG Strix XG129C, a 12.3-inch touchscreen secondary monitor for gaming dashboards, stream controls, and system stats.
A tiny second screen is quickly becoming the desk accessory gamers didn’t know they needed. and Asus is leaning hard into that idea with the ROG Strix XG129C.. Designed to sit under your main monitor. this 12.3-inch touchscreen display is built for quick checks of system performance. chat windows. and streaming controls—so you can keep your primary screen focused.
The Strix XG129C is priced at $199, positioning it as a dedicated “under-monitor” companion rather than a replacement display.. Asus frames it as a way to reduce distractions on your primary monitor. while giving you a more interactive surface for the tasks that usually interrupt gameplay or productivity.
At its core, the monitor uses a 1920 x 720 IPS panel with a 24:9 aspect ratio. That wide-but-short shape is intentional: it’s meant to fit naturally beneath a standard display without gobbling up vertical space on the desk or competing for the same viewing real estate.
For interaction, Asus includes a 10-point capacitive touchscreen.. The controller supports multi-finger gestures and is also geared for shortcuts, hotkey execution, and streaming overlays.. The idea is that the secondary display isn’t just “view-only”—it’s a control surface that can respond quickly when you’re managing streams. monitoring apps. or juggling chat and alerts.
Even though it’s a secondary screen, the Strix XG129C’s color performance is a selling point. Asus says it covers 125% of the sRGB color space and 90% of DCI-P3, which should make gradients and overlay visuals look more vivid than you’d expect from a compact desk add-on.
One of the more distinctive elements is software bundling.. Asus includes a one-year AIDA64 Extreme subscription, turning the display into a real-time hardware dashboard.. Through exclusive ROG SensorPanel themes. it can track things like GPU load. CPU temperature. and fan speeds. providing the kind of live status updates that typically require alt-tabbing to desktop tools.
Connectivity is also designed for a tidy setup. A single USB-C cable is used for power, video, and touch at the same time, reducing cable clutter behind the monitor. For broader compatibility, there’s an additional USB-C port rated for 20W Power Delivery and an HDMI 1.2 port.
Where this product gets particularly interesting is how it compares to common alternatives aimed at creators and streamers.. Elgato’s Stream Deck, for example, is built around physical buttons rather than a true screen.. The Strix XG129C trades that button-first approach for a touchscreen display. aiming to deliver modern visuals and potentially more flexible on-screen control.
Competition in the “secondary display for creators” space is also highlighted by Asus itself.. The Strix XG129C’s most direct rival is described as Corsair’s Xeneon Edge. which has a 14.5-inch size and a similar price.. The difference. in Asus’s telling. is that the XG129C keeps the aspect ratio tighter and leans into ROG ecosystem integration—an approach that may appeal most to people already building a gaming setup around Asus ROG products.
The overall concept also evokes Asus’s own laptop feature.. The Strix XG129C is described as bringing a desktop version of the ScreenPad experience seen on Zephyrus Duo laptops.. Instead of a secondary display focused on a single machine. Asus is essentially translating that “always there” interface idea into a dedicated. desk-ready accessory—positioning it as a more intentional take on the dual-screen workflow.
