Key takeaways
- Screen Size: For a secondary display, 10 to 15.6 inches is the sweet spot. Smaller panels save desk space, while 15.6-inch options feel closer to a real laptop experience and offer more usable area for multitasking.
- Resolution: 1080p is ideal for sharp text and clean image quality at a compact size. Lower resolutions like 1366×768 or 1024×600 are acceptable for basic tasks such as chat windows or hardware monitors, but text clarity will suffer.
- Input Options: HDMI is essential for most PC setups, while USB-C simplifies cable management by carrying power and video through a single connection. VGA, BNC, and AV inputs are useful if you plan to connect legacy hardware or security devices.
- Stand and Mounting: A built-in adjustable stand or VESA mount support gives you flexibility for placement. Portable monitors with foldable stands are great for desks without monitor arms, while VESA-compatible models can be attached to a wall mount or adjustable arm.
- Portability: If you travel with a laptop or attend LAN events, weight and thickness matter. Look for ultra-slim panels under two pounds with protective sleeves, so your secondary screen survives transport without adding bulk to your bag.
What's inside
Adding a second monitor to your gaming setup is one of the easiest ways to boost productivity, keep Discord or OBS handy, or display system stats while you game. But not everyone has the desk space for a full-sized secondary display, and many PC gamers want something compact that pairs well with a high-end GPU without overwhelming their primary screen. A small second monitor solves this by giving you just enough extra real estate in a space-efficient footprint.

The Best Small Second Monitors Reviewed
InnoView 15.6″ Portable Monitor
This 1080p USB-C and HDMI panel is the standout pick for PC gamers who want a sharp, portable second screen. The built-in 90-degree adjustable stand and included protective sleeve make it easy to position alongside your main display and toss in a bag for travel.
13.3″ Small PC Monitor
With HDMI, VGA, BNC, AV, and USB inputs, this 1366×768 panel is a versatile compact option for users who need broad compatibility with older hardware. It is a solid budget choice for displaying chat, system temps, or media on a secondary screen without spending much.
Haiway 10.1″ Security Monitor
This 1024×600 display accepts HDMI, VGA, BNC, and USB inputs and includes a remote plus VESA 75x75mm mounting support. It is best suited as a tiny auxiliary screen for monitoring security feeds, Discord, or lightweight widgets where image sharpness is not critical.
Bolanle P2 In-Ear Monitor Amplifier
This is a personal audio monitor amplifier for stage and rehearsal use, not a visual display. PC gamers building a streaming or podcasting setup may find it useful for audio monitoring, but it does not function as a secondary screen for your desktop.
Behringer P2 In-Ear Monitor Amplifier
Like the Bolanle P2, this ultra-compact device is a headphone amplifier designed for live performance monitoring. It has no display functionality and is only relevant here for users who also need in-ear audio monitoring alongside their gaming or streaming rig.
Frequently Asked Questions
What size is best for a small second monitor?
Anything between 10 and 15.6 inches works well as a secondary display. For reading text comfortably, 15.6 inches at 1080p is ideal, while 10 to 13 inches is fine for compact widget or chat duty.
Can I use a portable monitor as a permanent second screen?
Yes. Portable monitors with USB-C and HDMI work perfectly as fixed secondary displays. Just ensure your desk setup accommodates the stand or use a VESA mount if the monitor supports it.
Do I need a dedicated graphics card output for a second monitor?
Most modern GPUs include multiple outputs, and you can also use motherboard HDMI or a USB display adapter. Check your GPU’s port count before buying, especially on high-end cards that may only have three display outputs.
Is 1080p necessary on a small secondary monitor?
For text clarity and general usability, 1080p is strongly recommended. Lower resolutions like 768p or 600p are usable for basic monitoring tasks but will look noticeably soft when displaying fine text.
Final Thoughts
For most PC gamers, the InnoView 15.6-inch Portable Monitor is the best all-around small second monitor thanks to its 1080p resolution, USB-C connectivity, and built-in adjustable stand. If you want something even more compact and affordable, the 13.3-inch Small PC Monitor and the Haiway 10.1-inch display are both solid options that trade image sharpness for a smaller footprint and broader input compatibility.
