The three main LCD panel types
Every LCD monitor uses one of three panel technologies: TN (Twisted Nematic), IPS (In-Plane Switching), or VA (Vertical Alignment). Each has a distinct personality. Understanding the differences saves you from buying a monitor that is wrong for your use case.
TN panels - speed above all else
TN panels switch pixels the fastest. Response times of 1ms gray-to-gray are common, and some high-end TN displays hit sub-millisecond transitions. This made TN panels the default choice for competitive esports players for over a decade.
Where TN falls short: Colors look washed out. Viewing angles are poor - tilt the screen even slightly and colors shift dramatically. Black levels are average. For any creative work or casual use, the compromises are too steep.
Best for: Competitive FPS players who prioritize response time above everything else.
IPS panels - the balanced choice
IPS (and its close relatives - Nano IPS, Fast IPS, AHVA) offers accurate colors, wide viewing angles, and good brightness. The color gamut covers sRGB reliably, and many IPS panels cover DCI-P3 for HDR content.
Where IPS falls short: Black levels are mediocre. IPS panels exhibit IPS glow, a silver-ish brightening in corners when viewed in the dark. Response times have improved dramatically - modern Fast IPS displays hit 1ms - but older IPS panels lag behind TN.
Best for: Most people. Designers, photo editors, gamers who want good color, content creators.
VA panels - contrast kings
VA panels deliver the highest contrast ratios of the three - often 3000:1 to 6000:1 vs. IPS at 800:1 to 1500:1. In a dark room, VA blacks look genuinely black. This makes VA excellent for watching films and HDR gaming.
Where VA falls short: Smearing. VA panels suffer from slow pixel transitions on dark tones, causing a blurry trail behind moving objects. They also exhibit black crush - shadow detail that blends into solid black.
Best for: Movie watchers, console gamers, HDR enthusiasts who care about deep blacks.
Side-by-side comparison
| TN | IPS | VA | |
|---|---|---|---|
| Contrast ratio | 600:1–1000:1 | 800:1–1500:1 | 3000:1–6000:1 |
| Color accuracy | Poor | Excellent | Good |
| Viewing angles | Narrow | Wide | Wide |
| Response time | Fastest | Fast (modern) | Slower on darks |
| IPS glow | No | Yes | No |
How to test your own panel
Use the Contrast Test to measure your monitor's apparent contrast ratio, and the Viewing Angle Test to see how colors shift off-axis. If you are evaluating a used monitor or wondering which type you have, the color shift pattern at an angle reveals the panel type immediately.
