Match refresh rate to the frame rate your computer can actually deliver, use independent response-time and input-lag measurements, and evaluate brightness by its test window and duration. A 240Hz OLED is already exceptionally fast; 360Hz or more is worthwhile mainly for competitive players whose hardware can sustain those frame rates. For HDR, a small-window peak tells you about highlights, while sustained full-screen brightness tells you whether a bright desktop or daylight scene will remain bright after the panel’s automatic brightness limiting (ABL) engages.
OLED pixels switch quickly enough that modern models rarely differ as dramatically as their advertised millisecond figures imply. The useful comparison combines measured response and overshoot, refresh-rate behavior, HDR window and full-screen results, room lighting, coating, text clarity, variable-refresh-rate (VRR) behavior, and burn-in protection.

What refresh rate changes—and what it cannot change
Refresh rate is the maximum number of times a monitor can update each second. It does not create extra frames; the GPU and game must render them. At 240Hz, one refresh takes 4.17 milliseconds. At 360Hz, it takes 2.78 milliseconds. The theoretical difference is therefore about 1.39 milliseconds per refresh, and you only see it when a new frame is ready in time.

| Use case | Practical target | Why |
|---|---|---|
| Office work, browsing and video | 120–165Hz | Smooth scrolling and cursor movement without paying for a refresh rate your applications rarely use. |
| Most PC gaming | 240Hz | A strong high-end baseline when the system can render well above 165 frames per second at the chosen resolution and settings. |
| Competitive esports | 360Hz | Useful when a powerful GPU and a suitably optimized game consistently exceed 240 frames per second. |
| Specialist competitive setups | 480/500Hz or higher | Potentially lower motion persistence, but only valuable when frame rates, resolution and image quality remain acceptable. |
If your GPU cannot reach 360 frames per second, a 360Hz panel will not display 360 distinct frames each second. It can still run at a lower rate, but you are paying for headroom rather than receiving the full motion benefit. Resolution, game settings, VRR range and image quality may produce a larger improvement than moving from 240Hz to 360Hz.

Why frame pacing and VRR matter
A high maximum refresh rate does not fix uneven frame delivery. Enable the monitor’s adaptive-sync or VRR mode when supported, and compare reviews that test VRR behavior rather than only the headline maximum. A display that remains stable as frame rates move through its operating range can look smoother than a faster panel that exhibits flicker or loses synchronization.
Where the technology is heading
LG Display has announced a monitor panel rated at 540Hz. That headline establishes a direction for the market, not a universal recommendation. At those rates, the GPU must render extremely quickly, and buyers must decide whether they prefer the lower motion persistence or a higher resolution, stronger HDR image and clearer text at a lower refresh rate.
Is 240Hz OLED worth it over 165Hz?
For a gaming PC that can regularly produce more than 165 frames per second, 240Hz can make camera motion and aiming feel more immediate. The gain is smaller when frame rates stay near 165, when a game is CPU-limited, or when you play cinematic titles at settings that keep performance below the monitor’s ceiling. For productivity and console use, 120–165Hz is generally sufficient; choose 240Hz because your games and hardware can use it, not because OLED requires it.

How to read OLED response-time specifications
OLED pixels are emissive and can change state very quickly. Manufacturers commonly advertise a 0.03ms gray-to-gray (GtG) figure; LG lists 240Hz and 0.03ms GtG for the 27GS95QE-B, a 27-inch QHD OLED example. That number describes a specified operating mode and test condition. It is not a guarantee that every color transition, refresh rate or setting completes in 0.03ms.

What independent measurements should include
- Response at maximum refresh: Confirms whether the panel keeps up at 240Hz, 360Hz or its advertised ceiling.
- Response at 120Hz and 60Hz: Shows behavior for consoles, video playback and systems that do not run at the maximum rate.
- Overshoot and inverse ghosting: Reveals bright or dark trails caused by overdriving transitions. A tiny average number is not useful if artifacts are visible.
- Refresh-rate compliance: Checks whether the monitor actually accepts and displays the advertised signal reliably.
- Input lag: Measures processing delay between the signal arriving and the image appearing.
RTINGS describes Samsung’s Odyssey OLED G6 as having a “near-instantaneous response time” while reporting refresh-rate compliance and response behavior separately. That separation is important: pixel response is only one part of latency. A monitor can switch pixels rapidly and still add delay through scaling, image processing or other electronics, so compare measured input lag as well.
Why average response numbers can mislead
GtG is a family of transitions, not one universal event. A manufacturer’s best-case transition may not represent dark-to-dark or difficult color changes. Look for a chart or table showing multiple transitions, the test refresh rate, overdrive setting and overshoot. Prefer a mode that remains clean across transitions instead of selecting the setting with the lowest single number.
Brightness: three measurements you must keep separate
OLED brightness is dynamic. Automatic brightness limiting can reduce output when a large portion of the screen is bright, protecting the panel and controlling heat and power. Consequently, a spectacular small-window peak does not predict how bright a white web page or full-screen game will remain.

HDR highlight brightness
This is the luminance of a small bright area such as a reflection, explosion or star. Reviews commonly use a 10% window; VESA’s DisplayHDR testing uses an 8% center patch for the relevant True Black tiers. It is the best indicator of highlight impact, but it represents only a small portion of the screen.

Brief full-screen flash
A display may produce a higher full-screen level for a short flash than it can hold continuously. This matters for a sudden bright scene transition, but not for a long white document or a sustained daylight scene.
Sustained full-screen output
This is the luminance a large white image can maintain after the panel has been bright for an extended period. It matters most in a bright room, for desktop work and for HDR scenes dominated by bright content. Always record whether a review reports a peak window, a brief flash or a long-duration full-screen result; comparing unlike measurements produces a false ranking.
What DisplayHDR True Black tiers actually guarantee
VESA defines DisplayHDR True Black for OLED and other emissive displays, with tiers from True Black 400 through True Black 1400. The tier specifies minimum performance under the certification test, not a promise that the monitor will sustain the tier number across the whole panel.
| DisplayHDR True Black tier | 8% center-patch minimum | Long-duration full-screen minimum |
|---|---|---|
| True Black 400 | 400 cd/m² | 250 cd/m² |
| True Black 500 | 500 cd/m² | 300 cd/m² |
| True Black 600 | 600 cd/m² | 350 cd/m² |
| True Black 1000 | 1,000 cd/m² | 500 cd/m² |
| True Black 1400 | 1,400 cd/m² | 700 cd/m² |
The lower full-screen minima explain why “1,000-nit OLED” and “500 cd/m² sustained” are not contradictory descriptions: they refer to different patterns and durations. VESA’s CTS 1.2 separates peak-window, brief full-screen and sustained full-screen tests, and its FAQ notes that HDR peak luminance depends on the scenario being measured.

Does True Black 400 mean the monitor is bright?
It means the monitor meets the certification’s 400 cd/m² minimum on the specified 8% patch and a lower long-duration full-screen requirement. It does not mean the entire screen will hold 400 cd/m² indefinitely. In a dark or controlled room, the OLED’s near-black performance and contrast may matter more. In daylight, sustained output and the screen coating become more important.
Independent reader supportYour contribution helps us test, update, and keep practical guides available for everyone.Match brightness to your room and content
Bright-room desktop use
Prioritize sustained SDR or full-screen brightness, reflections and anti-glare behavior. A panel with an impressive HDR peak can still look subdued when a bright browser or document triggers ABL. Check long-duration measurements and, where possible, view the coating in the lighting conditions where you will use the monitor.
HDR games and films
Prioritize the 10% or 8% highlight result, tone-mapping behavior and full-screen performance together. Tone mapping determines how the game’s or film’s mastered highlights are fitted to the panel’s capabilities; two monitors with similar peak numbers can therefore present different images. Confirm that HDR mode, the operating system and the application are configured consistently when comparing results.
Mixed SDR and HDR work
Check how easily the monitor switches modes, whether brightness changes are distracting, and whether ABL is visible during ordinary desktop tasks. A specification sheet rarely describes these transitions, so independent measurements and user controls are more informative than a single peak claim.

Other specifications that can outweigh a small refresh-rate difference
- Resolution and pixel density: A sharper image and cleaner fine detail may be more valuable than 240Hz versus 360Hz outside esports.
- Text clarity: OLED subpixel layouts and image processing can produce colored fringing or softer fonts. Read text-focused reviews, not only gaming benchmarks.
- Coating and reflections: Glossy and matte surfaces handle room light differently; neither peak-nit figure captures this.
- VRR behavior: Check the usable range, flicker and compatibility with your GPU.
- Burn-in mitigation and warranty: Look for pixel-shift, panel-refresh and static-image protections, and read the warranty’s coverage and exclusions. These protections can influence long-term ownership more than a small latency difference.
A practical buying process
- Measure your workload: Record the frame rates you actually reach at the target resolution in the games you play. Use a 240Hz target only when performance regularly supports it; consider 360Hz or more only when frames exceed 240 consistently.
- Set a brightness priority: For a bright room, make sustained full-screen output and reflections primary. For HDR games and films, record both the 8%/10% highlight result and sustained behavior.
- Verify certification: Note the exact DisplayHDR True Black tier and keep its 8% and long-duration requirements beside any retailer or manufacturer peak figure.
- Read independent response tests: Check maximum-refresh, 120Hz and 60Hz results, overshoot, inverse ghosting, refresh compliance and input lag.
- Check image fundamentals: Compare resolution, text rendering, coating, tone mapping and VRR behavior at the same time as the headline specifications.
- Review ownership safeguards: Confirm burn-in mitigation features and the warranty terms for your region before purchase.
Common specification mistakes
Buying 360Hz without 360 frames per second
The panel cannot display frames that the GPU does not produce. If your frame rate is lower, invest first in GPU capability, resolution balance or image quality.
Treating 0.03ms as total latency
That figure is a manufacturer GtG claim under a stated condition. It excludes signal-processing delay and may not describe every transition. Use independent input-lag and overshoot data.
Comparing unlike brightness figures
Do not compare a small-window peak from one monitor with a sustained full-screen result from another. Record window size, duration, HDR mode and certification method for every number.
Ignoring ABL
OLED brightness can fall as more of the panel becomes bright. If you work with large white windows or use the monitor in daylight, sustained measurements are the relevant evidence.
Bottom line for the three headline specifications
Choose 120–165Hz for general use and most console or productivity workloads, 240Hz as a sensible high-end PC-gaming baseline, and 360Hz or 480/500Hz only when your games and GPU can sustain the necessary frame rates. Treat 0.03ms as a marketing specification until independent tests show clean transitions, low overshoot and low input lag at the refresh rates you use. For brightness, read the HDR window and sustained full-screen figures together, then account for ABL, room lighting, coating and tone mapping. A balanced OLED with appropriate refresh, measured motion performance and honest brightness behavior is a better choice than the model with the largest isolated number.
