Our top picks
Best monitorA 27-inch 4K monitor with USB-C power delivery and hub — one cable from MacBook or Windows ultrabook for display, charge, and USB ports.
Best for: Laptop-primary workers who want the simplest second screen connection.
- +Single USB-C to laptop for many setups
- +4K clarity for text-heavy work
- +Built-in USB hub reduces dongle count
- −Monitor plus arm exceeds budget if starting from zero
- −M1 base chips limit to one external display without DisplayLink
Best hubConnects HDMI, USB-A, SD, and pass-through charging when your monitor lacks USB-C — the budget bridge between laptop and existing HDMI monitor.
Best for: Laptops with one USB-C port and an HDMI monitor already owned.
- +HDMI 4K output for external display
- +Adds ports laptop lacks
- +Desktop block — less strain on laptop port
- −Two cables if monitor lacks USB-C — hub plus charger
- −Not dual-monitor on most ultrabooks
Best ergonomics addA gas spring arm that holds the external monitor while laptop sits on stand to the side — aligns both screens at healthier heights on shallow desks.
Best for: Dual-screen ergonomics when desk depth is under 24 inches.
- +Reclaims desk depth under monitor
- +Easy height match between laptop on stand and external panel
- +Affordable vs built-in monitor stands eating space
- −Laptop screen still lower unless on stand — pair with riser
- −Requires VESA monitor

Side-by-side comparison
| Feature | Hub setup | Dock setup | Direct HDMI |
|---|---|---|---|
| Typical cost | $50 – $80 hub + monitor | $200+ dock + monitor | Cable only if port exists |
| Charging laptop | Pass-through on many hubs | Yes — dedicated PD | No — separate charger |
| Dual external monitors | Limited by laptop chip | Often yes on TB docks | Rare on base laptops |
| Best if you… | Single external screen | Daily plug-in workstation | Simple occasional second screen |
The short answer
Laptop plus one 27-inch external monitor is the most common productive WFH setup. Use USB-C monitor or hub for one-cable connection. Put the monitor on an arm, laptop on a stand — align top edges near eye level.
Check laptop display limits before buying two externals — Apple Silicon base models often allow only one external screen.
Second monitor beats wider laptop — more pixels and ergonomics for less than a laptop upgrade.
Laptop placement in dual setups
Do not leave laptop flat below monitor — neck strain follows. Use stand to raise laptop screen as secondary display offset left or right of main monitor.
Pick one primary screen — usually external 27-inch — for focus work. Laptop screen for Slack, email, or music.
Match scaling so window dragging between screens does not resize jarringly.
Connection paths
USB-C to USB-C monitor: cleanest — video, power, hub in one. HDMI via hub or dock: universal — works with most monitors and laptops. DisplayLink docks: workaround for one-display-limit Macs needing two externals.
Thunderbolt docks matter when adding ethernet, second 4K, and multiple USB devices daily.
How we chose these picks
Simplicity for laptop-first users guided monitor and hub choices — LG UP850 line is a frequent MacBook pairing. Anker hub for HDMI monitors already owned. VIVO arm solves depth on small desks.
We skipped ultrawide as default — 27-inch 16:9 pairs more naturally with laptop aspect ratios.
Common mistakes to avoid
Do not buy two monitors before checking M1/M2 display limits.
Avoid tiny 22-inch second screens — text too small next to laptop retina.
Do not skip laptop stand when adding external monitor.
Cheap HDMI cables fine at 1080p — use quality USB-C cables for 4K60.
The verdict
Connect a 27-inch USB-C monitor like LG UP850 for one-cable laptop workflow, or use Anker 555 hub with HDMI monitor you own. Add VIVO arm and laptop stand for ergonomics — second monitor setup fails when laptop stays flat on desk.

FAQ
Laptop closed or open with second monitor?+
Open with stand is better ergonomics — second screen plus raised laptop. Closed clamshell works with dock if you prefer single external only — requires external keyboard and mouse.
1080p or 1440p second monitor?+
1440p at 27 inches is sharper for text. 1080p saves money — acceptable at 24 inches. Match budget and desk depth.
MacBook Air one monitor limit?+
Base M1/M2 Air supports one external. Laptop screen plus one external equals two total displays. DisplayLink docks add second external with software tradeoffs.
Same brand monitor as laptop?+
Unnecessary — color match nice for photos, irrelevant for spreadsheets. Buy monitor on specs and price.
