There is no universal “best” OLED preset. HDR mode, brightness and refresh rate depend on your monitor model, the scene, your connection, and whether the source is a PC or console. Start with the monitor maker’s guidance, then configure the operating system and each game for that display.
Why one OLED setting cannot work everywhere
OLED gaming monitors do not all implement HDR controls, tone mapping or brightness behavior in the same way. A mode that produces convincing small highlights in a dark game may look less bright than another mode when most of the screen is already bright. Firmware, the monitor’s on-screen display (OSD), certification target and input device also affect the result.
The most important distinction is between a highlight peak and the brightness of a large bright scene. A specification such as “1,000 nits” usually describes a small test window, not a brightness level the panel can sustain across the whole screen. Your setting should therefore be chosen for the games and room in which you actually play, rather than by copying a number from another OLED model.
What HDR brightness figures really mean
Average picture level changes the result
Average picture level (APL) describes how much of the image is bright. A sword glint, muzzle flash or star is a low-APL event: most pixels remain dark while a small area becomes intense. A snowfield, bright user interface or daylight scene has a higher APL because a much larger part of the panel is bright.

- Samsung’s 27” Odyssey OLED G6 Gaming Monitor is engineered for perfection with a QD-OLED Display featuring QHD resolution made to deliver high brightness and a wide range of colors for gameplay
- OLED Safeguard technology supports performance by actively helping to prevent burn-in with a thermal modulation system
- Glare Free Technology keeps screen clear of reflection from external light sources
- The Pantone Validated screen accurately reproduces 2100+ lifelike colors and 110+ skin tone shades
- HDR10 provides brighter highlights and nuanced shadows for added depth and more realistic scenes
MSI explains this distinction for its OLED monitors. Its Peak 1000 mode reaches its headline 1,000-nit figure under an APL 3% condition. In MSI’s August 7, 2025 guidance, the company says: “In real-world usage, many scenes have a much higher average picture level (APL), and in these situations, True Black 400 / 500 can appear brighter than Peak 1000 nits.” That is MSI’s explanation of MSI monitor behavior, not a rule that applies automatically to every OLED display.
Certification is not a universal calibration value
MSI describes True Black 400 and True Black 500 as certification levels with at least 400 or 500 nits of minimum peak luminance and a maximum black-level luminance below 0.0005 nits. Those values describe the certification requirements as MSI presents them. They do not tell you which Windows slider, game slider or OSD value to select.
Likewise, an advertised peak number does not establish full-screen brightness, sustained brightness or a single correct HDR calibration point. Tone mapping, firmware and the selected HDR mode determine how the monitor maps the source signal to its panel.
Recommended Free Tools
Prepare the signal path before changing settings
- Identify the exact monitor model and firmware. Read that model’s manual and OSD descriptions first. Similar-looking OLED monitors can expose different HDR modes and brightness controls.
- Use the monitor input that supports your target mode. Check the specification for the required resolution, refresh rate, HDR and variable-refresh features. Do not assume every input has identical bandwidth.
- Verify the graphics device or console output. The source must support the resolution and refresh rate you want. A panel rated for 240Hz cannot force a graphics card, console, game or cable to deliver 240Hz.
- Set the display to its native resolution. Use the operating system or console display menu to select the monitor’s native mode before calibrating HDR.
- Confirm the active refresh rate. Check the system display information while the monitor is connected through the intended input. If the desired rate is missing, troubleshoot the connection before changing HDR sliders.
These checks prevent a common mistake: trying to fix a bandwidth or compatibility limitation with brightness or tone-mapping controls.
Choose an HDR mode for the scene, not the badge
| Mode or control | What the manufacturer describes | Where it may fit | Important qualification |
|---|---|---|---|
| True Black 400 / True Black 500 | MSI describes these certification levels as requiring at least 400 or 500 nits minimum peak luminance and a maximum black-level luminance below 0.0005 nits. | MSI recommends True Black 400/500 for its own monitors in bright environments and says it can appear brighter in scenes with higher APL. | These are MSI labels and recommendations. Other brands may implement HDR differently. |
| Peak 1000 | MSI says the 1,000-nit peak is achievable at APL 3%, a small bright area. | MSI recommends it for dark scenes containing small, intense highlights. | It is not a promise of 1,000-nit full-screen or sustained brightness. |
| EOTF Boost | MSI describes this as a proprietary option intended to increase brightness under the same APL. | Use it only if your MSI model provides the control and you prefer its brighter tone mapping. | Availability and behavior are model-specific; the setting can change the intended HDR response. |
Switch modes with representative content rather than a static desktop. Compare a dark game with lamps, sparks or stars against a bright outdoor level. If highlights look impressive but ordinary bright scenes look dim, the mode may be optimized for low APL. If bright scenes hold more visual weight in your games or your room is brightly lit, the True Black option may be the better fit on an MSI display that offers these modes.

Brightness settings: use model-specific guidance
LG 27GS93QE-B example
LG’s UK product page for the 27GS93QE-B gives one concrete model-specific setup for a brighter OLED image:
- Disable Smart Energy Saving.
- Select Gamer 1.
- Set Brightness to 100.
- Set Peak Brightness to High.
LG lists 250 nits minimum standard brightness and 275 nits typical standard brightness for this model. It advertises a 1,300-nit peak and ties its True Black 400 value to a 10% APL condition. The 1,300-nit figure should therefore be read as a peak specification under the stated measurement context, not as a sustained full-screen level.
What’s actually slowing this PC down?
Pick the symptom - the matching free tool is one click away.
LG also warns that disabling Smart Energy Saving and using the brighter settings can increase power consumption and may increase burn-in risk. Treat this as advice for the 27GS93QE-B, not a universal starting preset for every OLED monitor. If your model uses different control names or does not expose Peak Brightness, do not attempt to reproduce the numbers blindly.
Set room brightness separately from HDR peak
A brighter room can make a monitor appear less contrasty even when its measured output has not changed. Adjust ambient lighting and viewing position before deciding that the HDR mode is too dim. Avoid turning every control to maximum simply because a peak number is printed on the box; the appropriate choice depends on scene mix, room conditions, power use and the manufacturer’s stated trade-offs.
Configure the operating system and game
- Enable HDR at the source. In the operating system or console display settings, turn on HDR for the connected monitor. If the source continues sending SDR, changing the monitor’s HDR mode will not produce an HDR signal.
- Open the game’s HDR menu. Select the game’s HDR output option if it has one. Some games expose separate paper-white, peak-brightness or black-level controls; follow the on-screen reference images and the monitor’s documented capabilities rather than entering the panel’s advertised peak as an automatic value.
- Calibrate with the game’s test pattern. Adjust until the darkest symbol is barely visible and bright highlight details remain distinguishable. The correct target is the game’s clipping pattern on your display, not a universal Windows value.
- Check the result in several scenes. Revisit a dark scene, a bright outdoor scene and a scene with small highlights. A setting that is correct for one APL range can look different in another.
- Save a profile when the monitor supports it. Keep a known-good HDR profile separate from an SDR or competitive-gaming profile so that changing games does not erase your baseline.
There is no evidence for a single model-independent Windows HDR Calibration number. Certification names and peak specifications cannot be converted directly into one universal slider position.

Set refresh rate and adaptive sync together
Use the highest rate the complete chain supports
Refresh rate is limited by the monitor, resolution, input, cable, graphics device, operating system and game. Select the monitor’s advertised maximum only after confirming that every part of the chain supports it at the chosen resolution.
Two official product examples show why the details matter:
| Monitor example | Resolution and refresh specification | Input and sync details |
|---|---|---|
| LG 27GS93QE-B | QHD at 240Hz | HDMI 2.1; NVIDIA G-SYNC Compatible; AMD FreeSync Premium Pro; VESA AdaptiveSync |
| MSI MAG 272UP QD-OLED X24 | 4K at 240Hz | HDMI 2.1 with 48Gbps bandwidth; VRR; ALLM; console play up to 120Hz |
These are product specifications, not independent test results. They also do not mean that every port, cable, console or game will reach the panel’s maximum rate. On a console, the practical ceiling can be 120Hz even when the monitor is rated for 240Hz. On a PC, the achievable rate depends on the selected resolution, GPU output and game workload.
Enable variable refresh rate when the source supports it
Adaptive sync or variable refresh rate (VRR) lets the display follow changes in rendered frame rate instead of holding one fixed cadence. Enable the compatible VRR option in the source device and the monitor when both support it, then verify that the game is actually using the expected mode. If VRR is unavailable, confirm the input, cable, driver or console setting before changing HDR controls.
ALLM, where provided, is a console-oriented feature that can switch the display into a low-latency mode. The MSI MAG 272UP QD-OLED X24 specification lists HDMI 2.1, VRR and ALLM, with console play up to 120Hz. That capability still depends on the console, game and connection.

PC and console setup decisions
PC
- Use the monitor input and graphics output that support your target resolution and refresh rate.
- Turn on HDR in the operating system, then enable HDR in each game that supports it.
- Confirm the active refresh rate after enabling HDR; some display combinations expose different modes when settings change.
- Use the game’s own calibration pattern and assess both dark and bright scenes.
Console
- Check the console’s supported HDR, VRR and refresh modes at the monitor’s target resolution.
- Use an HDMI 2.1 path when the monitor specification requires it for the desired mode.
- Do not expect a 240Hz monitor to make a console render at 240Hz. The cited MSI example lists console play up to 120Hz.
- Run the console’s display checks after connecting the monitor, then tune the game’s HDR controls.
Troubleshoot common HDR and refresh problems
HDR looks dim in ordinary bright scenes
Check whether the monitor is using a low-APL peak mode. On MSI monitors, MSI says True Black 400/500 can appear brighter than Peak 1000 in higher-APL scenes. Try the model’s True Black option and compare the same bright scene. Do not infer that the monitor is defective from a difference between a small-highlight test and a full scene.
Small highlights look less intense than expected
Verify that the source is actually outputting HDR, the game’s peak setting is not clipping details, and the monitor is using the intended HDR mode. Peak figures depend on the test window; a large bright scene will not behave like an APL 3% highlight.
The advertised refresh rate is missing
Check the selected resolution, input, cable bandwidth, graphics output and display settings. Confirm the monitor manual’s requirements and test the connection at the target mode. A specification for 240Hz does not override a limitation elsewhere in the signal chain.
Brightness changes after enabling HDR
HDR and SDR are different signal modes. Recheck the operating-system HDR state, the monitor’s selected profile and the game’s HDR calibration. Keep separate profiles for SDR and HDR if your monitor supports them.
The Tool Desk

On the LG 27GS93QE-B, LG specifically cautions that its brighter setup can increase power use and may increase burn-in risk. Decide whether the extra brightness is worth that trade-off for your room and play pattern, and use the monitor’s OLED-care features and guidance where available.
How to compare OLED monitors or HDR modes
When evaluating two models or two OSD modes, compare the same five dimensions rather than ranking peak nits alone:
- Highlight peak versus bright-scene behavior: identify the APL or test-window context attached to each claim.
- HDR certification and tone mapping: note the certification level, the vendor’s explanation and the available controls.
- Refresh rate at your target resolution and input: a 240Hz claim is useful only if your GPU or console and connection can deliver it.
- Variable-refresh compatibility: check the exact VRR, adaptive-sync, G-SYNC Compatible, FreeSync or console features listed for the model.
- OSD trade-offs: record whether brighter modes disable energy-saving features or carry image-retention, burn-in or power-use cautions.
This framework avoids treating a certification badge or a manufacturer’s peak number as a universal calibrated setting. The available evidence supports manufacturer guidance and product specifications, not a single model-independent winner.
Quick Recap
A practical baseline checklist
- Read the exact model’s HDR and OLED-care instructions.
- Connect through the input and cable required for your resolution and refresh target.
- Select native resolution and verify the active refresh rate.
- Enable HDR at the operating-system or console level and in the game.
- Start with the manufacturer’s model-specific HDR mode guidance.
- Use the game’s calibration pattern instead of copying another monitor’s peak value.
- Compare a low-APL highlight scene with a high-APL bright scene.
- Enable compatible VRR and verify it in the source and game.
- Balance brightness against room lighting, power consumption and any stated burn-in risk.
- Save separate HDR, SDR and competitive-game profiles when the monitor allows it.
