IPS Monitor Ghosting Test
An IPS monitor ghosting test evaluates the pixel response time of In-Plane Switching panels — the most common display technology found in gaming monitors, laptops, and professional displays in 2026. Standard IPS panels have a GtG response time of 4–8 ms, which is imperceptible at 60 Hz but can produce light ghosting at 144 Hz. Fast IPS panels, introduced around 2020, push GtG down to 1–2 ms through improved liquid crystal alignment and more aggressive overdrive — making IPS viable for 240 Hz and 360 Hz gaming. The practical advantage of IPS over TN is wide viewing angles (170°/160°) and accurate colour reproduction (95%+ sRGB typical vs 75% for TN). The trade-off is that older IPS panels suffer from 'IPS glow' — a faint backlight bleed visible in dark scenes — and cannot match the ultra-fast sub-1 ms response of OLED. This test runs a moving object at four speeds so you can see the actual ghosting your IPS panel produces under gaming conditions and determine whether your overdrive setting is tuned correctly.

Frequently Asked Questions
Is IPS good for gaming response time?
Modern Fast IPS panels are excellent for gaming, achieving 1 ms GtG — matching TN panels while delivering far better colour accuracy and viewing angles. Standard IPS at 4–8 ms is fine for 60–144 Hz gaming but shows faint ghosting at 240 Hz+. For competitive FPS at 240 Hz or above, choose a monitor explicitly rated 'Fast IPS' or '1 ms IPS'. For 144 Hz gaming at any genre, standard IPS is completely acceptable.
Does IPS glow affect response time?
IPS glow is a backlight phenomenon separate from pixel response time. It appears as a faint whitish/yellowish bloom in dark corners, especially visible at an angle. It does not add milliseconds to GtG or make ghosting worse. However, in very dark game scenes, IPS glow can visually obscure ghosting trails, making your panel seem better in the ghosting test than it is in brightly-lit fast-moving scenarios. Test at both light and dark backgrounds for accuracy.
What is the difference between IPS and Fast IPS response time?
Standard IPS: 4–8 ms GtG. Suitable for 60–144 Hz gaming. Fast IPS: 1–2 ms GtG, achieved through improved liquid crystal switching speed and more aggressive overdrive firmware. Suitable for 144–360 Hz gaming. The 'Fast IPS' designation was coined by LG and adopted industry-wide around 2020. Key brands offering Fast IPS panels include LG (Nano IPS, UltraGear), ASUS ROG, and Acer Predator. When a monitor is rated '1 ms IPS', it uses Fast IPS technology.
Should I buy IPS or OLED for gaming response time?
OLED wins on response time (0.01–0.03 ms vs 1–4 ms for IPS). However, in 2026, OLED gaming monitors cost significantly more and carry burn-in risk with static HUD elements. For most gamers, a Fast IPS at 1 ms GtG is the best value. OLED is recommended if: (a) you play in dark environments where OLED's contrast advantage is visible, (b) you're playing at 240 Hz+ where even 1 ms IPS shows slight ghosting, or (c) budget is not a constraint.
Why does my IPS monitor ghost more in dark scenes?
IPS dark-to-dark pixel transitions are slower than typical grey-to-grey GtG specs. Manufacturers measure GtG on mid-grey transitions where IPS is fastest. Dark-grey-to-dark-grey transitions can be 2–3× slower than the spec. This is why dark game scenes (shadow corridors, night environments) show more smearing on IPS panels. Enable your monitor's Black Frame Insertion (BFI) if available — it adds a dark frame between each image frame, reducing perceived motion blur at the cost of brightness.
How do I reduce ghosting on my IPS monitor?
1. Increase overdrive one step at a time until ghosting disappears — stop before inverse ghosting (bright halo ahead of moving objects) appears. 2. Ensure you're running at the monitor's native refresh rate in Windows Display Settings. 3. Disable any extra post-processing (gaming modes, noise reduction). 4. If you're at 60 Hz on a 144 Hz IPS monitor, upgrade your cable to DisplayPort 1.4 or HDMI 2.0. 5. Use the fast background (white) in this ghosting test — ghosting is most visible on high-contrast transitions.
