Asus ROG Strix, Espresso, and UPERFECT all make portable monitors, but they're really selling three different lifestyles — a battery-powered gaming screen for handhelds and consoles on the road, a premium color-accurate second display for Mac and iPad creatives, and a budget-friendly workhorse for anyone who just wants more screen without spending like it's a luxury purchase. I traveled with all three over six weeks — one for a gaming-heavy trip, one for client work needing accurate color, one as a backup for hotel-room spreadsheet days — and the gap between them was less about screen quality and more about who each one was actually designed for.
None of these are "the best portable monitor" in isolation. The right one depends entirely on what you're plugging it into and why.
Asus ROG Strix XG17AHP: built-in battery changes what "portable" means
The XG17AHP is a 17.3-inch, 1080p, 240Hz IPS panel with a genuinely useful trick the other two don't have: a built-in 7,800mAh battery, meaning it doesn't need to be tethered to a power source or even your laptop's battery to run. List price sits around $599, though I've regularly seen it discounted to the $445–$499 range. It comes bundled with a detachable tripod and a matte anti-glare coating that held up well even in a sunlit hotel lobby.
This is squarely a gaming monitor first — I used it mostly with a Steam Deck and a Switch 2 during downtime on a trip, and the 240Hz refresh rate genuinely mattered for fast-paced games in a way it wouldn't for spreadsheet work. The trade-offs: at just over two pounds without the stand, it's noticeably heavier than either competitor here, and the height-adjustment lock on the tripod felt loose enough that firm pressure could still shift the screen. If you don't game on the go, the battery and refresh rate are wasted weight in your bag.
Espresso: the premium choice for Mac and iPad users, priced like it
Espresso makes two relevant tiers — the base Display 15 at $299, a 1080p panel without touch or speakers to hit that price, and the Pro 15 at closer to $549–$599, which adds a 4K touchscreen panel, 550 nits of brightness, and a magnetic Stand+ accessory that lets you tilt and rotate the screen with real precision. Build quality on both is genuinely excellent — aerospace-grade aluminum that feels closer to an Apple product than a third-party accessory, which is clearly the point.
Where Espresso earns its "pricey" reputation is the comparison math: a similarly specced portable monitor from a lesser-known brand can run a fifth of the cost. I found the Pro 15 legitimately worth it for color-sensitive work — reviewing photo edits and checking layouts looked meaningfully better than on either competitor — but the minimalist two-USB-C-port design with no HDMI at all means older laptops or non-USB-C devices need an adapter you'll have to remember to pack. This is a monitor built specifically for the Mac and iPad crowd, and it shows in both its strengths and its price tag.
UPERFECT: the budget option that doesn't feel like a budget compromise
UPERFECT's lineup is enormous — sizes from 13.3 to 18.5 inches, resolutions from 1080p to 4K, refresh rates up to 144Hz, with most models landing between $70 and $240 depending on specs. I used a mid-range 15.6-inch 1080p model with a built-in kickstand for spreadsheet and email work during hotel-room mornings, and for that use case, it was hard to justify spending more. Brightness topped out lower than either competitor at around 300–400 nits, which showed in bright rooms, and the single-source backlight produced some uneven brightness at the edges under close inspection.
The honest caveat that shows up across independent reviews and buyer feedback: quality control is more of a mixed bag at this price tier — occasional dead pixels and stand designs that feel less refined than Espresso's magnetic system. For everyday productivity use where you're not pixel-peeping or color-grading, though, it genuinely covers the basics well for a fraction of what the other two cost.

| Weakest point | Heavy, loose height-lock | No HDMI, expensive for the spec | Mixed QC, lower brightness |
Which one should you actually pack?
If gaming on handhelds or consoles while traveling is the actual use case, the Asus ROG Strix's built-in battery and high refresh rate solve a real problem the other two don't even attempt to. If your work depends on accurate color and you're already living in the Apple ecosystem, Espresso's Pro 15 is worth the premium — just plan around the lack of HDMI. And if you mainly need a bigger, better screen for everyday work without a luxury price tag, UPERFECT covers that job well enough that spending three times more would be hard to justify for most people.

FAQ
Does the Asus ROG Strix XG17AHP need to be plugged in to work?
No. Its built-in 7,800mAh battery lets it run independently of a power source or your laptop's battery, which is its main advantage over the other two monitors here.
Why doesn't the Espresso Pro 15 have an HDMI port?
Espresso designed it around a minimalist USB-C-only setup aimed at modern Mac and iPad users; anyone needing HDMI will need to carry a separate adapter.
Is UPERFECT a reliable brand for portable monitors?
Generally yes for everyday use, though independent reviews and buyer feedback note more inconsistent quality control at this price tier compared to premium brands like Espresso.
Which of these three is best for photo or video editing?
The Espresso Pro 15's 4K resolution, 550-nit brightness, and wide color coverage make it the clear choice for color-sensitive creative work among these three.
Can any of these portable monitors be used with a gaming console?
The Asus ROG Strix is built specifically for this use case with its high refresh rate and battery independence; the other two can technically connect but aren't optimized for gaming performance.
