A touchscreen monitor is one of the best upgrades for teaching math online. Being able to write equations and annotate slides directly on the screen, instead of wrestling with a mouse, makes lessons clearer and far more natural. Here are the five best touchscreen monitors for online teaching in 2026, from a fold-flat all-rounder to a portable travel pick.

1. Dell 24″ Touch Monitor (P2424HT) – Best all-around

The Dell P2424HT is the touchscreen most teachers should buy first. Its 23.8-inch full-HD panel folds nearly flat like a drafting table, so you can write equations naturally, and a built-in USB-C hub powers your laptop and the display over one cable.

How to choose a touchscreen monitor for teaching

Look for at least 10-point touch and a screen that tilts or folds flat so you can write comfortably. A USB-C connection that carries video, touch, and power on one cable keeps your desk tidy. Size is a personal call: 24 inches suits most desks, 27 to 32 inches gives more room to annotate, and a portable 15-inch model is ideal if you teach on the go. Note that some Windows touch monitors don’t support touch on macOS.

For most online teachers, the fold-flat Dell P2424HT is the best all-around pick. Want more room? The CUNPU 27″ spreads out beautifully, while the LG 32″ 4K Swing is the premium showpiece. Teaching on the move? The InnoView portable packs into a bag, and the ASUS VT229H keeps things affordable.

Frequently asked questions

Do I need a touchscreen monitor to teach math online?

No, but it helps enormously. Writing equations directly on the screen with your finger or a stylus is far more natural than using a mouse, and it makes your explanations clearer for students.

Can I write on these monitors with a pen?

Most support finger touch and a basic stylus. For true pressure-sensitive handwriting, a pen display like the Wacom One is purpose-built, but a fold-flat touch monitor like the Dell P2424HT works well for everyday annotation.

Do touchscreen monitors work with a Mac?

Many touchscreen monitors only support touch on Windows. macOS doesn’t natively support touch input, so check the listing, or use a USB-C model and a stylus app if you’re on a Mac.
