5120x2160 100Hz Android Desktop Mode on Razor Fold
A user reports achieving a desktop-like experience on a Motorola Razr foldable phone by connecting it to a 5K2K (5120x2160) ultrawide monitor running at 100Hz via the device's desktop mode.
Background
- The Motorola Razr+ (2025) folds in half like a classic flip phone, with a main inner screen and a smaller outer "cover" display on the front.
- "Desktop mode" lets Android phones output video to an external monitor, keyboard, or mouse for a PC-like experience — similar to Samsung DeX or the Steam Deck's desktop UI.
- 5120×2160 is 5K resolution with a 21:9 ultrawide aspect ratio, well beyond the typical 1080p/1440p range. 100 Hz smoothness is rare for phone desktop modes, which usually cap at 60 Hz.
- This post reports that the Razr+ can drive that high resolution and refresh rate smoothly via its USB‑C port, signaling Motorola's desktop mode is catching up to (or even surpassing) Samsung DeX in capability.
