Viewing Angle Test (IPS vs VA vs TN Gamma & Color Shift)
Check how much your monitor's colors, skin tones and dark-grey contrast shift when viewed from the side, above or below. Estimate whether your panel behaves like IPS, VA or TN and dial in the right sitting position.

What this viewing angle test checks
Almost every LCD monitor spec sheet claims "178°/178° viewing angles", yet a VA TV or a TN esports monitor looks completely different at 35° off-axis compared to an IPS or OLED display. That spec-sheet number only defines the angle where contrast drops to 10:1—it ignores gamma shift (mid-tones washing out into pale silver) and color phase shift (skin tones turning jaundiced or cyan turning purple). Placing identical reference pods at the center and all four corners lets you see off-axis shift even while sitting still in front of a wide screen.
Before you start
Sit dead-center at your normal working distance (60–75 cm) with the screen perpendicular to your line of sight.
Turn off auto-brightness sensors and privacy filters so room reflections don't masquerade as panel drop-off.
How to run the test
Click Start fullscreen viewing-angle test above.
Step 1 — Dead-center check (0°): Look straight at the center pod. Compare its brightness and saturation against the four corner pods without moving your head. On a large flat VA monitor, the four corners often look slightly paler than the center even from straight on ("VA viewing cone").
Step 2 — Horizontal 45° check: Lean two steps to the left and right. Watch whether the red, green, blue and skin-tone quadrants hold their hue or wash out.
Step 3 — Vertical ±30° check: Stand up to view the screen from 30° above, then crouch so your eyes sit below the bottom bezel.

How to read your results (OLED vs IPS vs VA vs TN)
OLED & IPS at 45°Hue and gamma stay stable; IPS loses ~15–25% luminance and shows slight corner glow on black.VA panel at 45° ("VA cone")Deep shadows lift into silvery grey once viewing angle exceeds 20–30°, which is why many large VA screens are curved.TN panel from below (-30°)Vertical viewing angle inverts like a photo negative—never mount a TN monitor in portrait orientation.

When results can be misleading
Portrait (90° rotated) monitors: When you rotate a monitor 90° into portrait mode, its weak vertical viewing angle becomes your horizontal left-to-right viewing angle. A TN or VA monitor mounted vertically on the side of your desk will look severely washed out or inverted unless it is angled directly toward your face.
Curved monitors viewed from off-center: A steep 1000R curved VA monitor is engineered to keep every pixel perpendicular to a viewer sitting 60–80 cm dead-center. If a second person sits beside you on a couch, the far side of the curve sits at an extreme angle to them.
How can I tell if my monitor is IPS, VA or TN without looking up the model number?
Stand up and crouch 30° below the screen while looking at our 5-pod pattern. If the image turns dark and photo-negative from below, it is a TN panel. If vertical angles stay stable, switch to our Dark/Mid-Grey Checkerboard and lean 40° to the side: if dark grey squares wash out into pale silver while dead-center blacks look very deep, it is a VA panel. If colors and mid-tones stay consistent from every direction, it is IPS or OLED.
Why do the edges of my flat VA monitor look lighter than the center even when I sit straight in front of it?
That is the "VA viewing cone" (off-axis gamma shift). When you sit 55 cm in front of a 27-inch or 32-inch flat monitor, your eyes strike the center at 0° but hit the left and right edges at 22–28°. On VA liquid crystals, that 25° angle is enough to lift dark-grey gamma, making the edges look lighter than the center. Sitting slightly further back reduces the angle.
Which panel type is best for a vertical (portrait) second monitor?
IPS or OLED. Both maintain consistent gamma across both axes, so rotating the panel 90° does not cause left-to-right eye mismatch. Avoid TN panels in portrait orientation—your left eye and right eye will see two different brightness levels.
Does viewing angle affect color calibration with a hardware colorimeter?
Yes. A colorimeter puck rests flat against the center of the glass (0° angle), so it calibrates only for dead-center viewing. On a wide VA monitor, a patch that measures Delta-E < 1 in the center can still shift past Delta-E 4 near the side edges.
