Portable monitors turn your Steam Deck, ROG Ally, or Legion Go into a full desktop setup — a "decktop." We look at the best all-rounder KYY portable monitor and the essential USB-C hub accessory to make it work on the go.
You've got a Steam Deck, ROG Ally, or Legion Go — a handheld PC that can play almost anything. But sometimes you want a bigger screen. A desk. A proper setup. That's where portable monitors come in, turning your handheld into what the community calls a "decktop."2
The idea is simple: one USB-C cable carries video, power, and data to a slim monitor that fits in a backpack. Plug in, prop it up, and you've got a dual-screen workstation or a bigger gaming canvas wherever you are.
Most portable monitors use IPS LCD panels — they're bright, affordable, and good enough for most games. OLED panels (like the ASUS ZenScreen OLED) offer deeper blacks and richer color, but cost more and can be harder to find in portable sizes.1
Refresh rate is another split: 60Hz is fine for strategy games and desktop work, but 144Hz makes a real difference in shooters and racing games. The ViewSonic Omni VX1755 is a rare portable that hits 144Hz.1
For most handheld gamers, a good 1080p IPS panel at 60Hz is the sweet spot — it matches what the Steam Deck and ROG Ally can comfortably drive, and keeps the price down.
The KYY 15.6-inch portable monitor is the practical choice for most handheld gaming PC owners. It's a 1080p IPS panel with USB-C connectivity that supports power delivery — meaning one cable from your Steam Deck or ROG Ally handles both video and power pass-through. It's slim, light enough to toss in a bag, and priced well below premium options.

|---|---|
| Screen | 15.6" 1080p IPS |
| Connectivity | USB-C (single-cable video + power) |

If you want a no-fuss monitor that just works with your handheld, this is it.
A portable monitor is only useful if you can actually connect things to it. A 7-in-1 USB-C hub solves the biggest headache of handheld gaming PCs: not enough ports. With HDMI, USB-A, SD card reader, and power delivery passthrough, you can connect your monitor, charge your device, and plug in a mouse or controller — all at once.
| Spec | Detail |
|---|---|
| Ports | 7-in-1 (HDMI, USB-A x2, USB-C PD, SD/microSD) |
| Power Delivery | Yes (passthrough) |
| Size | Pocket-sized |
This isn't glamorous, but it's the difference between a frustrating cable-tangle and a clean, functional desk setup.
We focused on two things: single-cable simplicity and real portability. The KYY monitor connects via USB-C with power delivery — no separate power brick needed. The USB-C hub adds the ports your handheld is missing without adding bulk. Together they make a decktop setup that actually travels well.
