Compare the lit screen with a 14-inch, 16:10 laptop display. Both are drawn to the same scale; cases and stands add to the footprint.

First, the screen you may already own

Supports $0: a second screen you may already own · The screen stays on one desk

An iPad beside a Mac: $0. Apple’s Sidecar turns a supported iPad into a second display for a Mac at no cost. It is a Mac feature and does nothing for a Windows laptop, a Steam Deck or an Android tablet; our Mac mini guide lists Apple’s full requirements.

A TV or desk monitor already in the room. If the second screen will live at one desk, a portable buys portability, not screen area, and a TV or spare monitor you own will almost always be larger. Buy a portable when the screen has to travel or the desk has to pack away; our Steam Deck guide makes the same point for a handheld.

What we will not recommend. Hard Bargains has tested no software that turns a spare laptop or tablet into a second display and has verified no independent measurement of it, so we name none.

What to buy under $100 — and what the next dollars buy

Supports A strict $100 ceiling · The best-measured pick, just over $100 · Denser text

The table at the top carries the picks; this is how much weight each deserves. The shortlist is narrow, four listings from one budget maker plus one Dell, none tested by Hard Bargains, and the strongest measured evidence sits on the Z1FC alone, so the Z1C’s and Z1RC’s strengths are Arzopa’s specifications. Checkout promotions move (Arzopa’s advertised Z1C checkout price went from $94.99 on Sept. 15 to $84.99 on Sept. 16), so confirm the final price, seller, cables, sleeve and return terms for the exact variant, and treat a crossed-out “original” price as no evidence of a bargain.

Model	Price observed Sept. 15	What it is useful for	Evidence and catch
Arzopa A1, black	$79.99 displayed; unavailable in the manufacturer’s product data	A reference point for a basic 15.6-inch, 1080p second screen	Earlier unit independently reviewed; current specifications differ and both colors are unavailable
Arzopa Z1C	$99.99; advertises $94.99 after checkout reduction	A 16.1-inch, 1080p specification candidate inside a $100 budget	We have not verified an independent measurement review for this exact model

Arzopa Z1FC, gray with sleeve	$109.99; advertises $104.99 after checkout reduction	At advertised checkout prices, adds a sleeve for no extra cost over black	Related model listing, not a separately measured recommendation
Arzopa Z1RC	$149.99; page advertises $113.99 at checkout	A 16-inch, 2560×1600/60Hz specification candidate for denser text	Resolution is manufacturer-listed; we have not established its measured image quality here

What a genuinely cheap screen can do. ServeTheHome’s review of the MNN M156F01, a 15.6-inch 1080p screen at about $50 when reviewed, found it serviceable as another display with weaker color than its Dell reference and measured about 6.2 watts, so do not pay to solve a color problem your work does not have.

Size and the packed kit. A 16-inch 16:10 panel is almost as wide as a 15.6-inch widescreen but nearly an inch taller, and a bigger 1080p screen makes the same pixels larger rather than adding desktop space; the size tool above draws them to scale. Weigh the whole kit: a folding cover protects the panel but may offer few stable angles, a kickstand adjusts more freely but leaves the screen exposed, and the Z1FC ServeTheHome reviewed listed no sleeve, while the gray listing includes one — and if the cover is not enough, what your screen can attach to has the thread and VESA specifications the makers publish.

What the measurements actually tell us

Supports The best-measured pick, just over $100 · Compact and bright, costs more · Color-critical photo or design work · Gaming

• Arzopa A1. Tom’s Hardware’s review, published Dec. 26, 2024, measured 228 nits and 66.4% sRGB and found it usable for office documents. Today’s listing has different brightness, contrast and panel specifications, so those figures may not describe a unit bought now.
• Arzopa Z1FC. ServeTheHome’s March 6, 2026, review measured 98% sRGB and power use of 3.5 watts at minimum brightness, 5.8 watts at half and 9 watts at maximum. That is one 144Hz sample; later bundles may differ.
• Dell Pro 14 Plus P1425. Tom’s Hardware’s review measured 409 nits and praised its build and stand, including portrait use. It has two USB-C video inputs and no HDMI, and its lit area is smaller than a 16-inch screen’s.

How to read the next review you find

Look for measurements of the exact model, such as brightness, reflections, side-angle readability and stand stability, rather than a star average across variants. Color coverage is not color accuracy, and figures above 100% often describe gamut volume, so paid color work needs an actual accuracy and uniformity report. A 144Hz or HDR label states a capability, not fast pixel response, low input lag, working variable refresh or bright highlights; look for a review that tested those things.

This decides whether a portable monitor is useful or a returned box, and it depends on the machine you already own. A USB-C connector alone establishes nothing: the same shape is used for charging-only, data and video ports. DisplayPort’s USB-C explanation describes how video travels through compatible ports; check your computer’s exact port specification and use a cable rated for video.

Find your output at the top of the diagram, then read down to the arrangement it needs. Every figure in it appears in the text below, with its source.

Find your source

Find your source: what decides it for a MacBook, a Mac mini, a Steam Deck, a Switch 2, an iPad, a Windows laptop or any HDMI output

Your video source	What decides it	Where the detail is
MacBook, any Apple silicon model	The chip caps how many external displays run at once, and a dock does not raise that number. A portable counts as one of them	Your chip’s display limit
Mac mini, 2020 M1 through 2023 M2 Pro	Any Thunderbolt port carries video	Ports and display limits by model
Mac mini, 2024 and later	Use a rear Thunderbolt port or HDMI. The front USB-C ports do not carry video	Ports and display limits by model
Steam Deck or another handheld	One USB-C port carries both the video and the charger, so the two have to share it	How the Deck gets power
Nintendo Switch 2	Nintendo’s TV-mode instructions use its dock, the Switch 2 AC adapter and an Ultra High Speed HDMI cable, and give no dock-free route. Unless a monitor’s maker states Switch 2 direct video in writing, plan on the dock plus separate power for the monitor	The dock question
iPad with USB-C	Whether Apple lists your model for moving apps and windows to an external display. On an older model not on that list, such as the iPad (A16), plan on a bigger copy of the iPad screen. Apple’s current iPad Air is newer than the list	Mirror or extend
Windows laptop, USB-C port	The connector shape establishes nothing. Look for “DisplayPort Alt Mode”, a DisplayPort logo beside the port or a Thunderbolt symbol. If the specification does not name video, that port carries charging and data only	The laptop maker’s port specification for your exact model
Any HDMI output	HDMI carries video and never power, whatever else you buy	The monitor’s own power adapter

Pass-through: look for a wattage in writing

Pass-through means the monitor takes power from its own adapter and sends some of it back to the device supplying the video, so one cable at the source both drives the screen and keeps a laptop or handheld charged. Do not assume a monitor’s spare USB-C socket can charge your laptop; look for pass-through with a wattage in the maker’s specifications, and see our Steam Deck guide for three listing phrases that look like pass-through and are not.

Dell’s store page for the Pro 14 Plus P1425 lists “2 USB-C ports (DisplayPort 1.2 Alt Mode, Power pass-through of up to 65W),” and ASUS’s ZenScreen MB16FC specifications list “Power Pass-through : Max. 65W.” We re-read both pages Sept. 16, 2026; Dell’s still listed a USB-C cable but no power adapter in the box. Those are manufacturer statements, not measurements, and no review we have found tested charging a computer through either monitor. Arzopa’s Z1C and Z1FC pages state no pass-through at all.

What the monitor costs you in power

Power draw: measured watts and what they cost a battery

ServeTheHome measured the Z1FC at 3.5 watts at minimum brightness, 5.8 watts at half and 9 watts at maximum, while Arzopa rates the Z1C at 8 watts and the Z1FC at 10 watts, which are maker ratings rather than measurements. On battery that adds up: in an idealized model, not a battery test, a 60 watt-hour battery running a 15-watt laptop lasts 4 hours, and adding a 9-watt display cuts that to 2.5 hours.

Nintendo Switch 2: the dock question comes first

Nintendo Switch 2: plan on the dock; what each screen's maker says, and firmware changes

The short answer. Plan on the dock. Nintendo’s instructions put a Switch 2 on another screen through its dock, and no screen on our shortlist has a written dock-free Switch 2 route. With a portable, that means the dock, Nintendo’s adapter for it and a separate USB-C power supply for the monitor. The console’s own screen costs nothing, and if a TV is already in the room, the dock and HDMI cable you use with it give you a bigger screen for $0.

Screen	What the maker says, read Sept. 16	Verdict
Arzopa Z1C	No Switch 2 statement found on the product page. Arzopa’s Switch 2 guide says to “use HDMI from dock to monitor and skip USB-C video for the console”	Needs the dock: its HDMI to the monitor’s mini-HDMI input, plus USB-C power for the monitor
Arzopa Z1FC	The product page lists “Switch” without naming a model. The same Arzopa guide applies	Needs the dock, by the same route
Arzopa Z1RC	Arzopa’s Switch 2 guide names a Z1RC listing as its “strongest all-around pick,” connected through the dock’s HDMI. ServeTheHome’s May 23, 2026, review lists a mini-HDMI input	Needs the dock, by the same route
Dell Pro 14 Plus P1425	Dell’s store page does not mention the Switch 2	Unknown. It has USB-C inputs only, so the dock’s HDMI needs an HDMI-to-USB-C converter, which Dell does not list

Why the usual USB-C check fails here. Nintendo’s TV-mode instructions list the console, the Switch 2 dock, the Switch 2 AC adapter (model NGN-01) and an Ultra High Speed HDMI cable, give no dock-free route and say the original Switch’s AC adapter cannot power the Switch 2 dock for TV mode. In a Nintendo Q&A reported by Notebookcheck on April 7, 2025, Nintendo’s Koichi Kawamoto said video output is limited to the console’s bottom USB-C port, so a “Switch compatible” listing written for the original console does not settle this.

Firmware can change the answer. Notebookcheck reported Nov. 13, 2025, that Switch 2 system update 21.0.0 stopped video output through most of the third-party docks it described, so test any travel dock inside the return window and again after a system update.

Power at the table. The dock route needs two power sources: Nintendo’s adapter for the dock and a USB-C supply for the monitor, as Arzopa’s guide also says. Try a USB-C charger you already own first; Arzopa’s Z1C page, checked Sept. 15, recommends a power adapter that supports 5V/3A or above if the picture flickers or restarts.

Find USB-C PD wall chargers on Amazon only if you have no spare. This opens search results, not a specific product or a Switch 2 compatibility recommendation; check the exact model and seller.

iPad with USB-C: mirror or extend

iPad as the source: which models extend to a second workspace and which only mirror

This is the reverse of Sidecar: here the iPad supplies the picture and the portable is its display.

The short answer. Check whether Apple lists your iPad for moving apps and windows to an external display. If your model is on Apple’s list, a portable can be a second workspace. If it is an older model not on the list, such as the iPad (A16), plan on a bigger copy of the iPad screen, which suits presenting or watching video but does not give you a second place to work. Apple’s current iPad Air is newer than the list; see below before deciding.

Apple’s Stage Manager page lists the iPad Air (M2 and M3), iPad Pro (M4), iPad Pro 12.9-inch (5th generation and later), iPad Pro 11-inch (3rd generation and later) and iPad Air (5th generation). Apple’s current iPad Air (M4) is newer than that list, and its specifications name one external display without saying whether it extends or mirrors, so check Apple’s page again before buying a screen for it.

The iPad (A16) is not on the list; its specifications describe “video mirroring and video out” to one external display at up to 4K and 60Hz.

Power. Apple’s specification pages list no power output for the iPad’s USB-C port, so plan on the monitor’s own USB-C supply, and charging the iPad through the same cable needs a monitor with written pass-through or a hub with a power input.

Using one with a Mac mini

Mac mini: which ports carry video and where the display limit is

On 2024 and later Mac minis the front USB-C ports carry no video, so use a rear Thunderbolt port or HDMI, and on any mini a portable counts toward Apple’s display limit. Our Mac mini desk setup guide has ports and display limits by model, and portable monitors for a Mac mini covers power, screen density and packing.

Use the return window to test your actual setup

Six checks inside the return window: text, windows, sleep and wake, the stand, dead pixels and the packed bag

Supports A strict $100 ceiling · The best-measured pick, just over $100 · Denser text · Compact and bright, costs more

Keep the packaging and test the complete arrangement early:

1. Open your normal document at the text size and distance you will use, beside a window and at night.
2. Extend the desktop rather than mirror it, and move windows between screens.
3. Disconnect, reconnect, sleep and wake with your intended cable and charger; a setup that needs fiddling is not a travel setup.
4. Try the stand on your real table, including portrait if needed, and check cable strain, mouse clearance and wobble while typing; if it wobbles or sits too low, check what your screen attaches to before buying a stand.
5. Inspect solid light and dark backgrounds for pixel defects and unevenness, and read the seller’s actual defect and return policy.
6. Pack the protected screen, cables and power gear in the bag you will carry; if the kit stays home, the portable has failed its main test.

Buy the least expensive setup that passes those checks for your work, including no purchase at all if the first section already gave you a second screen. For many second-screen jobs a modest 1080p panel is enough. Pay more when the extra money fixes something you can see or feel every day.
