Onn portable monitors are Walmart's own house-brand screens, and in the entry tier of the best budget portable monitors they are consistently the cheapest option on the shelf. That makes the obvious question harder to answer than it looks: a 15.6-inch 1080p panel with a folio stand and three cables in the box is a genuinely useful second screen, but the brand behind it is a retail label rather than a display maker, and almost none of the numbers shoppers normally lean on have been independently measured.
The lineup is smaller than most buyers expect. The current Walmart monitor catalog surfaces exactly two portable Onn models side by side — an established 15.6-inch FHD unit (Walmart item 100147048) and a newer listing (Walmart item 18695054387). Both are 1920 × 1080 IPS at 60 Hz. Neither adds touch, OLED, a battery, a higher refresh rate, or a larger panel. Onn does sell high-refresh desktop monitors, which is the main reason searches for the brand turn up screens that have nothing to do with the portable range.
This guide treats the two SKUs as two separate products instead of merging their specs into one generic "Onn 15.6" entry. It covers what each monitor actually ships with, which numbers are Walmart's official figures, how each connects to laptops, consoles and handhelds, and how the pair stacks up against the Arzopa, KYY and UPERFECT panels that dominate the same tier.
It is written for the buyer who wants a second screen on a tight budget and needs to know where the compromises land — and who is prepared to trade some polish, documentation and mounting flexibility for the lowest price in the category.
What Onn Is — Walmart's House Brand
Onn is Walmart's private-label electronics brand, listed among the retailer's own labels in Walmart corporate material. It is not a monitor specialist. There is no Onn display division publishing calibration reports, no firmware download portal for the portable screens, and no tuning utility comparable to ASUS DisplayWidget or ViewSonic vTouch. What Onn provides instead is Walmart's distribution and Walmart's return path, wrapped around hardware built to hit an entry-tier price.
That trade has predictable consequences. Documentation for these two monitors is thin at the edges — the parts of the spec sheet that matter most to a careful buyer are not uniformly spelled out — and where a figure is published, it is a manufacturer number carried by Walmart rather than a bench measurement. No major monitor-review outlet has published a lab test of either current Onn portable model, which is the single biggest difference between shopping Onn and shopping any of the specialist budget brands in this tier.
The range is also deliberately narrow. The current Walmart catalog lists two Onn portable monitors and nothing else. There is no Onn 13-, 14-, 16- or 17-inch portable monitor, no Onn touchscreen portable, no Onn OLED portable, and no Onn 120 Hz or 144 Hz portable model currently on sale. Onn's high-refresh products are conventional desktop monitors, not portables.
Where Onn fits, then, is simple: a first second-screen or a travel backup, bought on price and convenience, from a retailer you can walk into. It is not a brand you choose for measured color accuracy, high refresh, mounting systems, or long-term ecosystem support — and the lineup below shows exactly why.
The Onn Portable Monitor Lineup — Two 15.6-Inch Models
Both current Onn portable monitors are 15.6-inch 16:9 IPS panels at 1920 × 1080 and 60 Hz. That is the entire lineup. The difference between them is not panel performance — it is what each one ships with and how completely each is documented at retail.
| onn 15.6" FHD (100147048) | onn 15.6" (18695054387) | |
|---|---|---|
| Screen | 15.6 in IPS, 16:9 | 15.6 in IPS, 16:9 |
| Resolution | 1920 × 1080 | 1920 × 1080 |
| Refresh rate | 60 Hz | 60 Hz |
| USB-C ports | 2 | 2 |
| mini-HDMI | Yes | Yes |
| Built-in battery | No | No |
| Primary retail channel | Walmart | Walmart |
onn 15.6" FHD Portable Office Monitor, with Cable, Black — Walmart item 100147048
The longer-running of the two, and the one that answers most of the "does a cheap Walmart monitor work" questions. It is still sold new by Walmart, with open-box and refurbished copies of the same SKU circulating alongside it.
- Panel: 15.6-inch IPS LCD, 1920 × 1080, 16:9, 60 Hz, anti-glare coating
- Contrast: 1200:1
- Weight: 2.43 lb
- Ports: 2 × USB-C, 1 × mini-HDMI, 1 × 3.5 mm headphone output
- Audio: two built-in 1 W speakers
- Stand: folio cover that folds into a multi-angle viewing stand
- In the box: 1.5 m mini-HDMI cable, 1.5 m USB-C-to-USB-C cable, 1.5 m USB-A-to-USB-C cable, folio cover, quick start guide
- Battery: none
- Operating systems: Windows, macOS, ChromeOS
Two details drive most of the buying decision here. The first is the bundle: a folding stand plus all three cables means the monitor is usable the moment it leaves the box, which is not true of every budget panel in this tier. The second is the headphone jack and the 3.5 mm output, useful once you discover how thin the onboard 1 W speakers sound — they are a convenience feature for system chimes and video calls, not a substitute for laptop audio or headphones.
The 60 Hz refresh rate is the ceiling to plan around. A reseller listing advertises this SKU at 100 Hz; Walmart's own specification places it in the 60 Hz assortment, and long-running buyer documentation for the model identifies the same figure. Treat 60 Hz as the real number for console and gaming planning.
One-cable USB-C operation works where the host port carries display output, and the supplied USB-C-to-USB-C cable supports laptop video and power in that configuration. It is host-dependent, not universal — the requirements are covered in the connection section below.

onn 15.6" Portable Office Monitor, with Cable, Black — Walmart item 18695054387
The current 2026 listing, sold and shipped by Walmart.com. It shares the panel class of the older model — 15.6-inch, 1080p, IPS, 60 Hz — but publishes a fuller specification set at retail.
- Panel: 15.6-inch IPS LCD, 1920 × 1080, 16:9, 60 Hz
- Brightness: 250 nits
- Response time: 4 ms
- Viewing angles: 178° horizontal / 178° vertical
- Dimensions: 14 in W × 8.3 in H × 0.45 in D
- Ports: 2 × USB-C, 1 × mini-HDMI
- In the box: one USB-C cable
- VESA: not compatible
- Battery: none
This is a thinner chassis than the older model's folio design at 0.45 inches, and it is the only one of the two with a published brightness and response figure. Buyer reports on the Walmart listing describe a protective sleeve and simple setup, including a MacBook running the monitor directly from the laptop over USB-C without a separate charger — a real-world report rather than a lab certification, but consistent with how single-cable USB-C is supposed to behave on a DisplayPort Alt Mode host.
Two things to plan for. The formal box contents list a single USB-C cable, so an HDMI source or a second screen in your bag means bringing your own mini-HDMI cable. And the newer model is confirmed non-VESA, so mounting it on an arm is not an option out of the box.

The newer model is not a performance upgrade over the older one. Both display the same 1920 × 1080 at 60 Hz; the newer panel is the better-documented product, the older one is the better-equipped product. Picking between them comes down to bundle and price, not image quality — a point worth holding onto given how similar the two listings look side by side.
What Onn Portable Monitors Don't Offer
This is the section that decides most purchases, because the current range is deliberately narrow. If any item on this list is a requirement, Onn is not the brand for you:
- No 120 Hz or 144 Hz panel. Both current models are 60 Hz. That caps console output at 1080p60 and rules out high-refresh gaming entirely.
- No touchscreen. There is no Onn portable touch display in the current catalog. Touch input is a different product class, and the best touchscreen portable monitors all come from other brands.
- No OLED. Every current Onn portable is IPS LCD.
- No 2.5 K or 4 K resolution. Both models sit at 1920 × 1080, the lowest resolution in their price tier.
- No built-in battery. Neither monitor runs untethered; both need power delivered over USB-C or from a charger, which matters for airline use and for handhelds drawing from their own battery.
- No size options. The portable range stops at 15.6 inches. There is no 14-inch travel model and no 17-inch desk model.
- No mounting hardware. The newer model is confirmed non-VESA, and neither monitor ships with a bracket or adapter. A tablet stand or tray is the practical route to getting the screen off a flat surface.
- No dedicated accessory kit. Onn sells general electronics accessories, but there is no Onn-branded portable-monitor case, stand or screen protector sold as a separate product.
Onn vs the Budget Competition — Arzopa, KYY and UPERFECT
The Onn sits in the same tier as the Arzopa Z1RC, KYY K3 and UPERFECT BE156JF — 15.6-inch-class 1080p-or-better IPS panels with dual USB-C and mini-HDMI. Four differences actually separate them.
Resolution. Arzopa's Z1RC steps up to a 16-inch 2560 × 1600 panel while holding 60 Hz, so its desktop workspace and text density sit clearly above the Onn's 1080p. If sharp text is the priority, the Onn's 1080p is the lowest-resolution option in this bracket.
Evidence behind the numbers. This is the sharpest contrast. KYY's K3 has been independently measured — TechRadar recorded 262 nits, 940:1 contrast, 64% sRGB and 47% NTSC. Onn's published specifications are Walmart's manufacturer figures, and neither current Onn model has an equivalent measurement record. For a buyer comparing panels rather than price tags, that difference in evidence quality is the real story of this tier.
Connectivity and mounting. UPERFECT's BE156JF offers a genuine 75 × 75 mm VESA pattern and a full-size HDMI port alongside its dual USB-C inputs, which makes it far easier to put on an arm or drive from a console without an adapter. The newer Onn is non-VESA and mini-HDMI only, and the older one uses mini-HDMI as well.
Bundle versus ecosystem. Onn's older SKU bundles a folio stand and three cables, which is genuinely more generous than most budget panels ship with. Arzopa and KYY counter with a deeper model range, published comparison documentation and wider retail availability — plus the fact that Arzopa publishes an entire lineup guide, which the Arzopa portable monitor brand guide covers model by model.
If Amazon is your channel, the closest like-for-like substitute is the KYY 15.6-inch FHD panel — the same size and resolution class, with independent measurements published behind it.

Connecting an Onn Monitor — Laptops, Consoles and Handhelds
The single most common mistake with any portable monitor is assuming that a USB-C connector means video. It does not. Video over USB-C requires the source port to support DisplayPort Alt Mode (or Thunderbolt/USB4 with display support), and the cable must be a full-function, video-capable USB-C cable rather than a charge-only one. A phone or laptop with a charging-only USB-C port will power the monitor and display nothing.
Laptops and MacBooks. One-cable operation works when the host port carries display output, and the older model ships with the USB-C-to-USB-C cable needed for it. The newer model has buyer reports of a MacBook driving and powering it over a single USB-C connection. Where the host does not support video over USB-C, the fallback is mini-HDMI for the image plus a separate USB-C power connection to the monitor. The full breakdown of which ports work and which do not is in the USB-C portable monitor guide.
PS5 and Xbox Series X|S. Connect the console's HDMI output to the monitor's mini-HDMI input and power the monitor separately. Because both Onn panels are 1080p/60 Hz, 1080p60 is the practical target. A PS5 or Xbox Series X can output higher frame rates on capable displays; that does not change the Onn panel's 60 Hz ceiling, and neither model should be treated as a 120 Hz gaming monitor.
Steam Deck. This is the strongest technical match in the lineup. Valve specifies DisplayPort 1.4 Alt Mode on the Deck's USB-C port, and the Onn's USB-C input is built for exactly that kind of source. Expect the Deck's own battery to drain faster while it powers the monitor — that is normal for bus-powered portable screens, and it applies to every brand in this tier.
Nintendo Switch. Use the dock's HDMI output into the monitor's mini-HDMI input. Nintendo documents up to 1080p over HDMI in TV mode, and Switch Lite cannot output to a TV at all. Direct Switch-to-monitor USB-C should not be counted on.
Samsung DeX and USB-C iPads. Both are host-device capabilities rather than monitor features. Samsung supports wired external displays on compatible Galaxy devices, and Apple supports wired external displays from compatible USB-C iPads, directly or through an AV adapter. Where the host supports it, the Onn behaves like any other external panel.
If you are setting one up for the first time, the step-by-step sequence — port selection, power order, cable checks — is in the portable monitor setup guide, and the console and handheld specifics are covered in the best portable monitors for Nintendo Switch and Steam Deck.
Which Onn Portable Monitor Should You Buy?
Choose the older 100147048 if you want everything in one box. It ships with a folio stand that folds into a multi-angle viewing support plus three cables — mini-HDMI, USB-C-to-USB-C and USB-A-to-USB-C — along with built-in 1 W speakers, a 3.5 mm headphone output, and the lighter 2.43 lb chassis of the two. For a first portable monitor bought as a single purchase, that bundle is the deciding factor.
Choose the newer 18695054387 if you already own a USB-C cable and a stand, and you want the fuller published specification along with the thinner 0.45-inch body. It is the current model, sold and shipped directly by Walmart, and it is the only one of the two with published brightness (250 nits) and response time (4 ms) figures.
Buy neither if your list includes touch, OLED, 120 Hz, 4K, an internal battery, or a screen larger than 15.6 inches. None of those exist in the current Onn portable range, and no amount of cable juggling changes it. For those needs, start from the best portable second monitor for a laptop roundup or the best portable monitors for laptops by budget and pick from brands that build the feature you want.
Shop on Amazon only? Then Onn is the wrong starting point. Both current models are Walmart-channel products, and the like-for-like Amazon substitutes are same-size 15.6-inch 1080p panels from KYY, Arzopa and UPERFECT.
Frequently Asked Questions
Q: Is Onn a good brand for portable monitors?
Onn is Walmart's private-label brand rather than a display specialist, so it competes on price, availability and Walmart's return path rather than on measured performance or ecosystem support. For a cheap second screen or travel backup, that trade is reasonable. For color-critical work, high-refresh gaming or long-term firmware support, the brand is not built for it.
Q: Is the Onn 15.6" portable monitor 60 Hz or 100 Hz?
60 Hz. Walmart's specification places the model in its 60 Hz assortment, and available documentation for the same SKU identifies it as a 60 Hz panel. A reseller listing that advertises 100 Hz for that item is incorrect and should not be used for purchase planning.
Q: Can you use an Onn portable monitor with a PS5 or Xbox?
Yes, through HDMI. Connect the console's HDMI output to the monitor's mini-HDMI input and power the monitor separately over USB-C. Both Onn panels are 1080p/60 Hz, so 1080p60 is the practical target — the monitor will not display 120 Hz even where the console supports it.
Q: Does the Onn portable monitor work with a Steam Deck?
It is a strong technical match. Valve specifies DisplayPort 1.4 Alt Mode on the Steam Deck's USB-C port, and the Onn's USB-C input is designed for that kind of source. Note that the monitor will draw power from the Deck, so battery runtime shortens while connected — a characteristic shared with every bus-powered portable display.
Q: Does the Onn portable monitor work with a Nintendo Switch?
Through the dock, yes. Switch TV mode outputs up to 1080p over HDMI, so dock → HDMI → monitor mini-HDMI is the documented route, with the monitor powered separately. The Switch Lite has no TV output mode, and direct Switch-to-monitor USB-C should not be relied on.
Q: Does one-cable USB-C work on an Onn portable monitor?
It can, provided the host's USB-C port carries display output and the cable is a full-function, video-capable USB-C cable. The older model ships with a USB-C-to-USB-C cable suited to that job, and buyer reports describe laptops driving and powering the monitor over a single connection. A phone or laptop with a charging-only USB-C port will not work this way.
Q: Can you buy an Onn portable monitor on Amazon?
Onn is Walmart's private-label brand and Walmart is the primary retail channel for both current portable models. Amazon's like-for-like alternatives are same-size 15.6-inch 1080p panels from KYY, Arzopa and UPERFECT, which are stocked there directly.
Q: Is the Onn 100147048 discontinued?
No evidence indicates the SKU is discontinued — Walmart continues to sell it new, while open-box, damaged-box and refurbished copies of the same model circulate through Walmart Marketplace and resellers. If you find it cheap second-hand, treat it as a condition variant of the active model rather than a discontinued generation, and check the seller's warranty terms.
Conclusion
Onn's portable monitor range is the smallest in the budget tier, and that is the honest headline: two 15.6-inch 1080p IPS panels at 60 Hz, sold through Walmart, with no touch, no OLED, no high refresh, no battery and no size options. Within those limits, the older 100147048 is the better-equipped purchase — a folio stand and three cables in the box, speakers, a headphone jack and a lighter chassis — while the newer 18695054387 is the better-documented one, with published brightness and response figures and a thinner 0.45-inch body. Neither is a performance upgrade over the other; they are the same panel class sold two ways.
The trade you accept is evidence and ecosystem. KYY's equivalent panel has independent measurements behind it, Arzopa offers a higher-resolution 16-inch option at the same 60 Hz, and UPERFECT adds native VESA mounting and full-size HDMI. What Onn offers in return is the lowest entry point and Walmart's return counter — which, for a first travel screen or a backup display, is a legitimate reason to buy.
If your requirements stop at "a cheap second screen that works," Onn covers them. If they extend to touch, OLED, high refresh, a bigger panel or a mounting system, the money is better spent elsewhere.
