TN Panel Response Time Test
A TN panel response time test measures the pixel transition speed of Twisted Nematic monitors — the fastest LCD panel type available. TN panels achieve GtG response times of 1–3 ms without aggressive overdrive, making them the go-to choice for professional esports players who prioritise motion clarity over colour accuracy. Unlike IPS panels, TN liquid crystals rotate along a single axis, requiring less voltage and time to switch states. This makes TN inherently faster than IPS or VA at equivalent overdrive settings. The practical trade-off is limited colour accuracy (75% sRGB coverage typical vs 95%+ for IPS) and narrow viewing angles (170°/160° horizontal, 160°/160° vertical — colour shifts noticeably when viewed off-axis). Most 240 Hz, 280 Hz, and 360 Hz gaming monitors historically used TN panels because only TN could reliably sustain sub-2 ms GtG at those refresh rates. In 2025–2026, Fast IPS and OLED have largely matched or exceeded TN speed, reducing TN's market share, but many competitive esports setups still run 1 ms TN panels for their proven low input lag and overdrive consistency. This test lets you verify your TN panel is performing to spec and your overdrive is correctly calibrated.

Frequently Asked Questions
Is TN better than IPS for response time?
TN panels have historically been faster than standard IPS at equivalent overdrive settings, achieving 1–2 ms GtG vs 4–8 ms for standard IPS. However, modern Fast IPS panels have closed this gap, reaching 1 ms GtG while maintaining IPS colour accuracy. As of 2026, TN still maintains a slight advantage in overdrive consistency — TN overdrive is predictable; Fast IPS overdrive varies more across transition colours. For most gamers, Fast IPS at 1 ms is the better all-around choice. For professional esports players where every millisecond matters, TN remains competitive.
Does TN panel have ghosting?
TN panels have very low ghosting at 1–3 ms GtG. In this test, a well-calibrated TN monitor on Normal overdrive should show no visible trailing at Slow and Normal speeds, and minimal trailing at Fast speed. At Extreme speed (1,920 px/s, ~360 fps equivalent), even TN panels may show slight ghosting trails. If your TN monitor shows heavy ghosting at Normal speed, check that overdrive is enabled in the OSD and that you're running at native refresh rate.
Why does my TN monitor look washed out at an angle?
TN panels use liquid crystals that rotate on a single axis, causing colour shift when viewed above or below the horizontal axis. Brightness and colour accuracy drop significantly when viewed more than 10–15° off-axis vertically. This is an inherent TN limitation, not a defect. If you share your screen with others or use a multi-monitor setup at an angle, IPS or VA panels offer much better off-axis viewing. TN's narrow angles are the primary reason many content creators avoid TN despite its speed.
What is the fastest TN monitor available in 2026?
The fastest TN panels offered 360 Hz at 1080p with 0.5 ms GtG. Notable models include the ASUS ROG Swift 360 Hz and the Alienware AW2521H (360 Hz TN). However, by 2026, OLED panels have surpassed TN in absolute speed (0.01–0.03 ms vs 1–2 ms) while matching or exceeding their refresh rates at up to 480 Hz. TN's speed advantage over IPS has also narrowed significantly. If buying new, OLED delivers better contrast, speed, and colour simultaneously.
Can I improve TN response time with overdrive?
Yes. Most TN monitors include an Overdrive (OD), Response Time Compensation (RTC), or AMA setting in the OSD menu. Start with 'Normal' or 'Medium'. If ghosting persists at your target test speed, increase one step. If you see a bright halo ahead of the moving block (inverse ghosting), your overdrive is over-compensating — reduce it by one step. Inverse ghosting on TN is more visible than on IPS due to TN's higher contrast.
Should I get a TN or OLED panel for competitive FPS in 2026?
OLED is the better choice for new builds if budget allows. OLED panels (0.01–0.03 ms GtG) eliminate ghosting entirely, offer infinite contrast, and are now available at 240–480 Hz. For existing TN users, there is no meaningful upgrade benefit from TN to Fast IPS unless you want better colour. The meaningful upgrade is TN → OLED. If price is a constraint, a well-tuned 1 ms TN monitor remains a competitive choice for esports gaming through at least 2027.
