With over half of a dozen external displays for laptops in its lineup, ASUS is a company that takes portable monitors seriously. Following that philosophy, this week the company introduced its rather unique ROG Strix XG17AHPE external LCD, a gaming-focused display offering a Full-HD resolution as well as a 240 Hz refresh rate with variable refresh support. The portable monitor even has its own battery, so it will provide a premium gaming experience even away from a power outlet.

The ASUS ROG Strix XG17AHPE portable display uses a 17.3-inch IPS panel with a 1920×1080 resolution and features a maximum brightness of 300 nits, a 1000:1 contrast ratio, a 3 ms GtG response time, and a maximum refresh rate of 240 Hz refresh rate with VESA’s Adaptive-Sync variable refresh rate technology on top of that. Traditionally for ASUS’s gaming monitors, the ROG Strix XG17AHPE supports GamePlus and GameVisual modes for various genres and types of content, Shadow Boost feature to lighten dark areas in games, and GameFast input technology. The LCD also comes with a stand that can be used to mount the display horizontally or vertically.

The ROG Strix XG17AHPE is aimed at gamers who want to have a bigger screen to play on while they are travelling, offering an expanded window into virtual worlds for a notebook, console, or even a smartphone. For example, there are 15.6-inch laptops with GPUs powerful enough to push games to 240 FPS, but these games will certainly look better on a larger monitor. Also, it can be used to expand screen real estate of a high-end 17.3-inch laptop (and play in a ’32:9’ aspect ratio). In a bid to further improve gaming experience, the portable display has a built-in ESS Sabre 9118 digital-to-analogue (DAC) for headphones and integrated 1W speakers.

The 17.3-inch portable display from ASUS ROG connects to its host system using a USB Type-C (with DP Alt Mode) or a Micro HDMI 2.0 connector and uses another Type-C port for charging. The monitor has its own 7800 mAh battery that provides up to 3.5 hours of gaming when using a 240 Hz refresh rate.

Otherwise as the display is based on a 17.3-inch panel, the ROG Strix XG17AHPE is not exactly a small device by itself, buyers are typically going to want an appropriate bag. Thankfully, the monitor is fairly thin and light itself; it measures 1 cm thick and weighs 1060 grams.

The external monitor is listed at ASUS’s website, so expect it to be available in the foreseeable future. Unfortunately, pricing has yet to be disclosed.

    I second that preference, but unfortunately the problem is the panels being manufactured - for some reason they're almost all either 1080p sRGB gamut and high refresh rate, or 4K Adobe RGB gamut and low refresh rate. There has been precisely one 1440p 120Hz 17.3" panel, and it was TN with funky colours.

    That new 4K 120Hz panel is interesting, but the colour accuracy seems odd and it's going to be expensive for as long as there's only one manufacturer producing them.

    Given that a display is normally the second most power hungry component of a laptop (after the CPU (and GPU if applicable)) this is not really surprising. Displays like this need to be very thin and light seeing how they are by nature secondary devices - meaning that you're also already carrying something else. The battery is thus kept small enough to keep it light, and is likely more comparable to a tablet battery than a laptop battery. Besides, gaming without access to a wall outlet for more than 3 ½ hours - especially at 240Hz - is rather utopian.

    It needs 2 USB-C? Why?
  • nandnandnand - Sunday, January 26, 2020 - link

    One is for video input, the other for power/charge. Or you can use the Micro-HDMI for video input.

    It's possible that it can actually run off just the one depending on the power delivery capabilities of the host device, but if not a secondary port is always a good idea.

    What is the point of having 17" external monitor? Is it 1993?
  • Valantar - Tuesday, January 28, 2020 - link

    Are you saying that normal >=24" monitors are travel friendly? Because they are quite the opposite. Some people might want this as a secondary display for a laptop. Some might want it as a companion to a powerful SFF PC (there are lots of backpack-friendly SFF cases capable of housing a powerful gaming PC). Either way this would allow for quality gaming while travelling. Some might want it as an alternative to desk-bound or couch gaming, e.g. for use in bed or if the TV is being used by someone else. You seem to think this is intended for stationary use when the whole point is its size, weight and portability. 17" CRTs weren't exactly portable either...

    1920x1080? Who is playing with such a resolution? 1w speakers, c'mon! I wouldn't pay for this monitor even 300 bucks.

    The price seems great, but I was thinking more about its features.
