You’re standing there, finger hovering over the glass, wondering if a 24 inch touch screen computer monitor is actually going to change your life or just give you a massive case of "gorilla arm." Most people think touch screens are for tablets. Or maybe those self-checkout kiosks at the grocery store that never seem to scan your onions right.
But on a desk? It’s a different beast entirely.
Twenty-four inches is the "Goldilocks" zone for workspace ergonomics. It is large enough to actually see what you are doing without squinting, yet small enough that you aren't swinging your arm like a windmill just to hit the "X" on a browser tab. Honestly, the shift from a mouse-only workflow to a hybrid touch setup feels clunky for about twenty minutes, and then suddenly, you're wondering why you ever clicked a scroll bar.
Why 24 inches is the weirdly perfect size
If you go bigger, like 27 or 32 inches, touch becomes a workout. Your shoulder starts to ache. If you go smaller, like 15 or 21 inches, you lose the screen real estate needed for actual "real" work like Excel or video editing. The 24 inch touch screen computer monitor sits right in that sweet spot where your arm's natural reach covers almost the entire panel.
Look at the ViewSonic TD2455. It’s a classic example of why this size works. It uses an in-cell touch sensor, which basically means the touch layer is built into the display rather than being a thick slab of glass on top. This reduces parallax—that annoying gap between where your finger hits and where the "ink" actually appears on the screen.
Precision matters.
Most office desks are about 24 to 30 inches deep. When you sit at a standard distance, a 24-inch panel fills your field of vision without requiring you to turn your head constantly. When you add touch to the mix, you’re usually leaning in. A 27-inch screen at that distance is overwhelming. It's like sitting in the front row of a movie theater. Your eyes get tired. Your neck gets stiff. But the 24-inch? It stays manageable.
The "Gorilla Arm" myth vs. Reality
You've probably heard the term. It was coined back in the 80s when designers first toyed with vertical touch screens. The idea is that your arm gets exhausted holding it out horizontally for long periods.

And yeah, if you try to use a vertical monitor like an iPad, you’re going to hate it.
The secret to actually enjoying a 24 inch touch screen computer monitor is the stand. You need a "dual-hinge" or "kickstand" design. Units like the Dell P2424HT allow you to pull the screen down toward your lap at a 60-degree angle. Now, you aren't reaching out; you’re reaching down. It’s more like a drafting table. This changes everything. You can scroll through a long PDF with your left hand while your right hand stays on the mouse for precision clicks. It’s a bimanual workflow that feels surprisingly natural once the muscle memory kicks in.
IPS vs. VA: Don't get the wrong panel
Let's talk tech for a second. Most touch monitors use IPS (In-Plane Switching) panels. There is a reason for this. When you touch a screen, you’re applying pressure. On an old-school TN panel or even some VA panels, you’ll see those weird "ripples" or "puddles" of light around your finger. IPS panels are much more structurally sound.
- IPS: Great viewing angles. You can tilt the monitor way back and the colors won't shift. Crucial for touch.
- VA: Better contrast, but the colors might look "washed out" if you’re looking at the screen from an angle while leaning over it to sign a document.
- Glossy vs. Matte: This is the big debate. Glossy looks prettier, but it’s a fingerprint magnet. Matte handles glare better but can feel a bit "scratchy" under the fingertip.
Microsoft’s own research into "Natural User Interfaces" suggests that humans prefer a bit of glide. If the friction is too high, your movements become jerky. Most high-end 24-inch touch displays use a chemically strengthened glass (like Gorilla Glass, but for monitors) with an oleophobic coating. That coating is what keeps the oils from your skin from turning the screen into a blurry mess by noon.
Who is this actually for? (It’s not just for artists)
People assume touch screens are for "creatives." You know, the folks drawing logos or retouching photos. Sure, they use them. But the real power users are often in places you wouldn't expect.
Think about music production.
Using a mouse to move a fader in a digital audio workstation (DAW) like Pro Tools or Ableton is frustrating. It’s one fader at a time. On a 24 inch touch screen computer monitor, you can use multiple fingers to mix. You can grab three faders at once. It turns your monitor into a virtual mixing console.

Then there’s the finance world. If you’re staring at 50 rows of data in a spreadsheet, being able to physically "flick" the page or pinch-to-zoom on a specific chart is faster than hunting for the tiny "+" sign with a cursor. It’s about reducing the cognitive load. You see thing. You touch thing. Done.
The hidden cost of "cheap" touch screens
You’ll see some off-brand 24-inch monitors on Amazon for $150. Avoid them.
The difference lies in the "Touch Points." A decent monitor will support 10-point multi-touch. This means the hardware can track all ten of your fingers simultaneously. Cheap ones might only support two points, or worse, use "optical touch" (cameras in the corners) which is notoriously glitchy. If a fly lands on an optical touch screen, the computer thinks you clicked. It’s a nightmare.
Stick to Capacitive Touch. It’s the same tech in your iPhone. It relies on the electrical conductivity of your skin. It’s fast, accurate, and doesn't trigger just because your sleeve brushed against the corner of the bezel.
Connection headaches you need to avoid
This is where most people mess up. They plug in the HDMI cable and then get mad when the touch doesn't work.
HDMI only carries video and audio signals. It does not carry touch data.
To make a 24 inch touch screen computer monitor work, you almost always need a second cable—usually a USB-A to USB-B "upstream" cable—connecting the monitor to your PC. This is the data bridge. If you’re lucky enough to have a modern laptop with USB-C (DisplayPort Alt Mode), you can do it all with one cable. One cord for video, audio, touch data, and even charging your laptop. It’s clean. It’s elegant. But check your port specs first! Not every USB-C port is created equal.

Real-world limitations to keep in mind
Let's be real: Windows 11 is better at touch than Windows 10 was, but it’s still not perfect.
Some buttons are just too small. You’ll find yourself stabbing at a tiny "close" icon three times before it registers. This is why a 24-inch screen is better than a 21-inch; those targets are physically larger.
MacOS? Forget about it. Apple famously refuses to put touch in macOS. If you plug a touch monitor into a Mac, it will basically act like a giant, clumsy trackpad unless you install third-party drivers like Touch-Base (UPDD). Even then, it’s a hacky experience. If you’re a die-hard Mac user, a touch monitor is probably a waste of your money.
Cleaning and Maintenance (The Gross Part)
Your hands are oily. Even if you wash them, you’re leaving behind a microscopic trail of skin cells and sebum. Within a week, a touch screen looks like a forensic crime scene.
Do not use Windex.
The ammonia in glass cleaners can strip away that oleophobic coating I mentioned earlier. Once that coating is gone, the screen will feel "tacky," and fingerprints will be much harder to wipe off. Stick to a dry microfiber cloth for daily cleaning. For the heavy-duty grime, use a 50/50 mix of distilled water and isopropyl alcohol, but spray it on the cloth, never directly on the glass.
Actionable steps for your setup
If you're ready to make the jump to a 24 inch touch screen computer monitor, here is exactly how to set it up for success:
- Check your mounting: Does the monitor have a VESA pattern (75x75 or 100x100)? If the stock stand doesn't tilt enough, you'll want an articulating monitor arm. This allows you to pull the screen flat against the desk when you want to write or navigate, then push it back for traditional typing.
- Adjust your scaling: Go into your Windows Display Settings and set the "Scale and layout" to at least 125%. This makes the touch targets larger and saves you from a lot of frustration.
- Update the firmware: Companies like Dell and HP often release firmware updates for their touch controllers to improve palm rejection. Check their support site immediately after unboxing.
- Clean your screen weekly: Don't let the oils build up. A clean screen has less friction and just feels more premium to use.
A touch monitor isn't a replacement for your mouse and keyboard; it’s an extension of them. It’s about those moments where it’s faster to just reach out and tap "OK" than it is to find your cursor across three different displays. It’s a subtle shift, but once you get used to it, a non-touch screen starts to feel like a broken TV.
Investing in a quality panel like the Philips 242B9T or the Planar PCT2485 might cost a bit more upfront, but the build quality—especially the edge-to-edge glass—makes a massive difference in how the device survives daily wear and tear. Choose the right stand, get your cables sorted, and you’ll actually find yourself reaching for the screen more than you ever expected.
