A side monitor is the unsung hero of a productive setup, the secondary display you turn vertically or angle beside your main screen for chat, docs, code, or reference material. It doesn’t need to be your flashiest panel, but the right size, refresh rate, and mounting flexibility make the difference between a cramped afterthought and a genuine workflow upgrade.
Below we cover how to choose a side monitor that complements rather than clashes with your primary display, then review a range of options from slim office panels to portable USB-C screens so you can find the ideal companion for your desk.

How to Choose the Best Side Monitor
- Orientation and pivot: If you’ll rotate it vertical for code or documents, prioritize a stand or VESA mount that pivots cleanly.
- Bezel width: Thin, near-borderless bezels keep the seam between your main and side screen minimal and less distracting.
- Refresh rate: 100Hz to 180Hz keeps scrolling and cursor movement smooth even on a secondary panel; 60Hz is fine for pure text.
- Connectivity: Match the monitor’s inputs to your spare ports, USB-C is ideal for laptops, while HDMI/DisplayPort suit desktops.
- Size and desk fit: A 22″ to 24″ panel usually balances beside a larger main monitor without dominating the desk.

Frequently Asked Questions
Does a side monitor need to match my main one?
Not exactly, but matching approximate height and color temperature reduces eye strain. Thin bezels help the two blend regardless of brand.
Should I mount my side monitor vertically?
Vertical orientation is excellent for code, chat, and long documents. Choose a panel with a pivoting stand or VESA mount to enable it.
Is a portable monitor good as a side screen?
Yes, options like the VILVA 15.6″ are perfect for laptops, adding a second display over a single USB-C cable with no bulky stand.
Do I need high refresh on a secondary screen?
For text and reference, 60-100Hz is fine. If it doubles as a gaming or media display, panels like the LG 180Hz are worth it.
