A touchscreen monitor is one of the best upgrades for teaching math online.

Here are the five best touchscreen monitors for online teaching in 2026, from a fold-flat all-rounder to a portable travel pick.

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

What is the best touch screen monitor?

For teaching math online, the Dell P2424HT is a strong all-round choice: its 23.8-inch full-HD screen folds nearly flat like a drafting table, so writing equations feels natural, and a built-in USB-C hub powers your laptop over one cable. For a bigger canvas the CUNPU 27-inch works well, and the LG Smart Monitor Swing 32 is the premium 4K option.

Is a touch screen monitor worth it?

For math teachers who explain problems live, it often is. Writing a fraction, sketching a graph or circling a step directly on the screen is quicker and clearer for students than drawing with a mouse. If you mostly show slides and rarely annotate, a regular monitor plus an inexpensive drawing tablet may be enough, and the budget ASUS VT229H keeps costs down if you want to try touch.

Can you use a touchscreen monitor with any computer?

It works with most computers that have a video output and a free USB port. The screen picture travels over HDMI, DisplayPort or USB-C, while touch input needs a USB connection, so connect both cables unless the monitor uses a single USB-C cable. Touch works natively on Windows, but macOS doesn’t support touch input, so Mac users should check the listing first.

Can you use a touch screen monitor with a laptop?

Yes. Many teachers plug a touch monitor into a laptop to get a larger writing surface for lessons. With a USB-C model like the Dell P2424HT, one cable can carry video, touch and power. The InnoView 15.6-inch portable monitor also runs off a single USB-C cable, so you can carry a second touchscreen in your bag and teach from anywhere.

How do you use a touch screen monitor with Windows 10?

Connect the video cable and the USB touch cable, and Windows 10 normally detects the touchscreen automatically without extra drivers. If touches land on the wrong display when you use two screens, open Control Panel, choose Tablet PC Settings, and use Setup to tell Windows which screen is the touch monitor. Then open a whiteboard app and test writing an equation.

What is 5 point touch screen?

A 5-point touch screen can register up to five fingers or touches at the same time, enough for pinch-to-zoom and most gestures. Many teaching monitors go further: the Dell P2424HT and InnoView portable both offer 10-point touch. For writing math with one finger or a stylus, the number of points matters less than accuracy and a comfortable writing angle.
