The Steam Deck's 800p screen is great for handheld play, but when you want to dock at a coffee table or hotel desk, a portable monitor unlocks a bigger, sharper experience. We tested four top contenders — from budget-friendly 1080p to stunning OLED — to find the best match for your Deck and your wallet.
the steam deck is a marvel of portable PC gaming, but its 7-inch 800p screen can feel cramped when you're trying to settle in for a long session. a portable monitor turns your deck into a full desktop setup wherever you are — hotel room, coworking space, or friend's couch. here are the best portable monitors for steam deck, tested for plug-and-play compatibility, display quality, and real-world portability.
| pick | rank | best for |
|---|---|---|
| kyy portable monitor 15.6" | 1 | best overall value |
| asus rog strix xg17 | 2 | high-end / 240hz gaming |
| uperfect 2k 17.3" | 3 | large immersive screen |
| innocn 15a1f oled | 4 | premium oled picture |
the pick for most people. the kyy 15.6" monitor hits the sweet spot of price, portability, and performance. it's a 1080p ips panel that connects to the steam deck via a single usb-c cable — no dongles, no external power required, thanks to displayport alt mode and sufficient power delivery.1
the 60hz refresh rate matches the steam deck's typical output for most modern titles, and the 15.6" size is a massive upgrade from the deck's native screen without being unwieldy to pack. the built-in speakers are basic but functional for casual use.
for the frame-rate chasers. the asus rog strix xg17 is the premium pick if you want buttery-smooth motion. it packs a 240hz refresh rate and a built-in 7800mah battery that powers the monitor for hours — meaning you can use it truly wirelessly with the deck.1
the 17.3" 1080p ips panel is bright and responsive, and the built-in stand is more adjustable than most portable monitors. yes, it's pricier and heavier, but if you play fast-paced shooters or fighting games where every millisecond counts, this is the one.
for the immersion seekers. the uperfect 2k 17.3" monitor gives you a bigger canvas and sharper resolution than the competition. the 2k (2560×1440) panel makes desktop navigation, indie games, and older titles look crisp and detailed.1
at 17.3", it's the largest screen here — great for media consumption and split-screen productivity alongside your deck. note that demanding modern games at 2k will push the steam deck's gpu, so you'll want to adjust settings or drop to 1080p for smoother frame rates.
for the picture-quality purists. the innocn 15a1f brings oled to the portable monitor space, delivering perfect blacks, infinite contrast, and vibrant colors that ips panels can't match.1 if you play atmospheric single-player games — think hollow knight, disco elysium, or cyberpunk 2077 — the oled panel makes them look stunning.
it's a 15.6" 1080p 60hz panel, so you're not getting high refresh rates, but the oled response times are instant. colors pop, blacks are truly black, and HDR content looks noticeably better than on any ips portable monitor in this class.
| feature | kyy 15.6" | asus rog strix xg17 | uperfect 2k 17.3" | innocn 15a1f oled |
|---|---|---|---|---|
| resolution | 1920×1080 | 1920×1080 | 2560×1440 | 1920×1080 |
| refresh rate | 60hz | 240hz | 60hz | 60hz |
| power delivery | usb-c bus-powered | built-in battery | usb-c bus-powered | usb-c bus-powered |
| key feature | best value | 240hz + battery | largest 2k screen | oled panel |
this is the most important feature. a monitor with usb-c dp alt mode can carry video, audio, and power over a single cable from your steam deck. without it, you'll need hdmi + separate power, which defeats the portability purpose. all four picks above support it.1
the steam deck can output power over usb-c, but not all monitors play nice. look for monitors that can run on the deck's power delivery (15w is typical for a portable monitor) without needing a wall plug. the kyy, uperfect, and innocn all work bus-powered; the asus has its own battery.
the steam deck's apu is roughly equivalent to a gtx 1050 ti / rx 6400 class gpu. in demanding modern titles, you'll get 30-60 fps at 1080p medium settings. a 240hz monitor like the asus is overkill for triple-a games but fantastic for lighter esports titles. a 2k monitor like the uperfect gives you sharper desktop use and indie gaming, but you'll need to turn down settings for demanding games.
15.6" is the sweet spot for backpack portability. 17.3" monitors are noticeably larger but still fit in most laptop bags. weight ranges from ~1.5 lbs (kyy) to ~2.5 lbs (asus with battery). consider your carry setup.
if the monitor doesn't turn on, check that your usb-c cable supports video (not all do). a usb 3.2 gen 2 cable rated for 4k60 is ideal.
the kyy portable monitor 15.6" is the best pick for most steam deck owners — it's affordable, lightweight, and works with a single cable. if you want the smoothest motion possible, the asus rog strix xg17 is unmatched. for a big, sharp screen, go uperfect 2k 17.3". and if you care most about picture quality, the innocn oled is a treat for the eyes.
