Here is a closer look at ASUS ROG Strix XG349C.

About

A 3440x1440 IPS ultrawide with native USB-C DP Alt Mode — sidesteps OLED burn-in risk entirely, but its scaler pillarboxes a 16:9 handheld signal rather than filling the screen, and its USB-C port carries too little power for sustained handheld charging.

Confirmed with

  • Notebook (generic)

    The internal scaler pillarboxes a standard 16:9 signal with side black bars rather than any kind of intelligent fill — expected behavior, but a real limitation for anyone hoping to fill the ultrawide frame. USB-C Power Delivery output is too low to sustain a high-performance handheld under real gaming load, resulting in a slow battery drain even while connected.

    Confirmed — caveat
  • Steam Deck

    Does not work as a power source — a Reddit comment notes the XG349C's USB-C output is not enough to power a laptop or Steam Deck.
