If you teach online, the ability to annotate directly on your screen changes how clearly you can explain a concept. A touchscreen monitor (or pen display) lets you write equations, mark up problems, and guide students through each step in real time. Here are strong touchscreen monitor picks for online teaching in 2026, with an emphasis on writing and annotation.

What to look for if you annotate a lot

If your lessons revolve around handwriting math, prioritize a screen that lies flat and responds precisely to a stylus. A dedicated pen display gives the most natural ink, while a fold-flat touch monitor handles everyday markup. Consider a portable model if you teach from more than one place, and always check that touch is supported on your computer.

For everyday annotation, the fold-flat Dell P2424HT is the best all-rounder, while the Wacom One 13 gives the most precise handwriting for working problems step by step. The InnoView portable travels well, the ASUS VT229H is the budget choice, and the CUNPU 27″ offers the most room to write.

Frequently asked questions

Can you make a monitor touch screen?

Yes, you can add touch to a regular monitor with a touch overlay frame that attaches over the screen and connects by USB. These frames usually use infrared sensors and work with Windows without much setup. They are an affordable fix, but less precise than a built-in touchscreen, which matters when writing small exponents or fractions during a lesson. For neat handwriting, a pen display like the Wacom One 13 is more reliable.

What is the best touch screen monitor for online teaching?

For online teaching, the most useful touchscreen is one you can write on comfortably while sharing your screen. The Dell P2424HT folds almost flat and has 10-point touch and a USB-C hub, which makes it easy to annotate slides on Zoom or Google Meet. If most of your lessons involve writing out math step by step, a pressure-sensitive pen display like the Wacom One 13 gives cleaner handwriting.

Is a touchscreen monitor good for a classroom?

A desktop touchscreen works well for a teacher’s station or small-group work, where students gather around one screen. A 27-inch model like the CUNPU gives enough room to solve a problem together. For whole-class instruction, though, most schools use a large interactive display or a projector, because a desktop monitor is too small to read from the back of the room. Connecting the touchscreen to a projector gives you both.

Are there portable touchscreen monitors?

Yes. Portable touchscreen monitors are thin, lightweight screens, often around 15.6 inches, that connect to a laptop with a USB-C or HDMI cable and fold into a cover stand. The InnoView 15.6 is one example for tutors who teach from different rooms or travel to students. Check that your laptop’s USB-C port supports video output; otherwise you will need an HDMI cable and separate power.

Why is my touch screen monitor not working?

The most common cause is the touch cable. Video travels over HDMI or DisplayPort, but touch usually needs a separate USB connection, so check that cable first. If touch responds on the wrong screen, open Tablet PC Settings in Windows and use Setup to assign touch to the correct monitor. Also update the monitor’s drivers, restart the computer, and wipe the screen edges, since dust can block infrared sensors.
