What Is a Viewing Angle Test?

Displays color bands to evaluate image quality from different angles.

Panel Comparison

Why Should You Run This Test?

If colors look washed out, inverted, or shift dramatically when you view your screen from an angle, your monitor may have poor viewing angles. This matters if you share your screen with others, use a wide or curved monitor, or sit slightly off-center.

Common Symptoms

  • Colors look different from the left vs. right side of a wide monitor
  • People sitting beside you see completely different colors on your screen
  • Dark areas look washed out or bright areas look dark when viewed from above/below
  • Presentation audience sees distorted colors on a projected display

What Causes Poor Viewing Angles?

Panel Technology

  • TN (Twisted Nematic) — Worst viewing angles. Colors invert and wash out beyond 30° off-center. Common in budget gaming monitors.
  • VA (Vertical Alignment) — Better than TN but contrast and color shift at extreme angles. Blacks may look gray from the side.
  • IPS (In-Plane Switching) — Excellent 178°/178° viewing angles. Colors stay consistent but may exhibit "IPS glow" (slight silvery glow at corners).
  • OLED — Near-perfect viewing angles with minimal color shift.

Other Factors

  • Anti-glare coating — Heavy matte coatings can scatter light and reduce off-axis clarity.
  • Curved display geometry — Ultra-wide curved monitors may show slight color variation at the far edges even with IPS.

How to Read Your Results

✅ Colors remain consistent from all angles — Your display has excellent viewing angles (likely IPS or OLED). Colors stay accurate even when viewed from the side, above, or below.

⚠️ Slight color shift or brightness change at extreme angles — This is typical of VA panels. Center viewing is accurate, but off-axis viewing shows contrast shift. Acceptable for single-user setups.

❌ Severe color inversion or washout from the side — Your display has a TN panel with narrow viewing angles. Colors are only accurate when viewed straight-on. This limits shared viewing and wide-monitor use.

How to Improve Viewing Angle Experience

  • Position your monitor straight-on — TN panels look best when viewed directly from the center at eye level.
  • Tilt your monitor — Adjusting the vertical tilt can improve color consistency for your seated position.
  • Consider a monitor arm — A VESA arm lets you precisely position the screen for optimal viewing angle from your seated position.
  • For shared viewing: choose IPS or OLED — If multiple people need to see the screen (presentations, pair programming), IPS or OLED panels provide consistent colors from all angles.
  • For curved ultra-wide monitors — Sit at the recommended viewing distance (usually 1.5-2× the screen width) for the most uniform experience.

✅ Good Result — Consistent Colors

All color bands should look vivid and distinct from any viewing position. Tilt your head left, right, up, and down — the colors should remain recognizable with no dramatic shifting, inversion, or washout.

⚠️ Moderate Shift at Angles

When viewed straight-on, colors look correct. But tilting your head 45° or more causes noticeable darkening, brightening, or slight color shifting. This is typical of VA panels — acceptable for single-user use.

❌ Severe Color Inversion

From even a small angle, colors dramatically change — reds become orange, blues become purple, and dark areas look washed out or inverted. This indicates a TN panel with very narrow viewing angles.
