Can Portable Monitors Replace Drawing Tablets?

Professional artists rely on low-latency input devices for digital creation

As portable monitors with touch capabilities become more advanced, many digital artists are wondering if they can replace dedicated drawing tablets. The key factor in this comparison is touchscreen latency - the delay between stylus movement and on-screen response.

Understanding Touchscreen Latency

What is Touchscreen Latency?

Touchscreen latency refers to the time delay between when you touch the screen with a stylus or finger and when that input appears visually on the display. For digital artists, lower latency means more natural, responsive drawing experience.

Typical latency measurements:

  • Professional drawing tablets: 5-20ms
  • Premium portable monitors: 20-50ms
  • Budget touchscreens: 50-100ms+

Testing Methodology

How We Measured Latency

We tested several popular portable monitors and drawing tablets using high-speed cameras (240fps) to precisely measure the delay between physical input and screen response.

Test conditions:

  • All devices tested at 60Hz refresh rate
  • Same stylus pressure (2048 levels)
  • Identical drawing software (Adobe Photoshop)
  • Room temperature 22°C ±1°

Results Comparison

Device Type Average Latency Pen Pressure Price Range
Wacom Cintiq 22 Drawing Tablet 8ms 8192 levels $1,500+
XP-Pen Artist 15.6 Pro Drawing Tablet 15ms 8192 levels $400-$600
INNOCN 15Q1F Portable Monitor 28ms 4096 levels $300-$500
ASUS ZenScreen Touch MB16AMT Portable Monitor 35ms 2048 levels $400-$600
Generic 15.6" Touch Monitor Portable Monitor 62ms 1024 levels $150-$300

Note: Latency under 20ms is generally considered acceptable for professional digital art. Most humans can't perceive differences below 10ms.

Can Portable Monitors Replace Drawing Tablets?

For Professionals

For professional digital artists and illustrators who rely on precise input and minimal latency, dedicated drawing tablets still offer superior performance. The Wacom Cintiq series remains the industry standard for serious creative work.

For Casual Users

For hobbyists, students, or professionals who only occasionally need drawing capabilities, high-end portable monitors can be a viable alternative. The INNOCN 15Q1F (28ms latency) and similar models provide decent drawing experience while serving multiple functions.

Key Considerations

Beyond Just Latency

When choosing between portable monitors and drawing tablets, consider these additional factors:

  • Pen technology: EMR (Wacom) vs AES (Microsoft) vs MPP
  • Surface texture: Drawing tablets often have paper-like surfaces
  • Shortcut buttons: Professional tablets include programmable buttons
  • Display quality: Color accuracy, brightness, and resolution
  • Multi-touch support: Some devices support touch gestures

Future Improvements

As portable monitor technology advances, we're seeing:

  • New display interfaces (USB4, Thunderbolt 4) reducing signal latency
  • Higher refresh rates (120Hz+) improving perceived responsiveness
  • Better pen technologies (Wacom EMR becoming available in monitors)
  • AI-assisted prediction algorithms compensating for latency

Prediction: Within 2-3 years, premium portable monitors may match today's professional drawing tablets in latency performance while offering greater versatility.
