What’s actually slowing this PC down?
Pick the symptom - the matching free tool is one click away.
There is no universal set of on-screen-display (OSD) values that is best for every 4K OLED gaming monitor. The right setup depends on the exact monitor, the input you use, the PC or console connected to it, and the game. Start by confirming the selected input’s supported signal modes, then enable the highest resolution and refresh rate your source and display both support, turn on compatible variable refresh rate (VRR), and calibrate HDR using the relevant system tools.
For monitor-specific picture modes, HDR options, and OLED care settings, follow the manual for your exact model. Values or instructions that work on one display may not transfer to another.

What “best settings” means for a 4K OLED monitor
A 4K panel has a resolution of 3840 × 2160 pixels, but that number alone does not tell you what signal a particular connection can display. A monitor’s maximum refresh rate may apply only to a particular input or device. The connected PC or console, cable, game, and monitor input all have to support the mode you want.

It helps to separate setup into three layers:
- Signal settings: resolution, refresh rate, HDR, VRR, and other features negotiated between the source and display.
- System calibration: the HDR controls in Windows or on the console, which help align the output with the display.
- Monitor picture and care controls: model-specific OSD options, including picture modes and OLED care features. Use the manual rather than copying a cross-model recipe.
Get the signal working first, calibrate HDR at the system level second, and use a game’s own HDR calibration last if it provides one. Game-specific controls vary, so follow the prompts in the game rather than applying a universal brightness figure.

This order also makes troubleshooting easier. If the desired refresh rate is missing, first check the connection and source capabilities rather than changing contrast or color controls. If the signal is correct but HDR looks too dim or highlights appear wrong, calibrate the system output and then the game. Make one change at a time so you can tell which layer affects the image.
Check the monitor and connection before changing settings
Find the exact model name and the specifications for the input you plan to use. Check the monitor manual or manufacturer’s specifications for supported resolution and refresh rate on that input, then compare them with the output capabilities of the PC or console. Do not assume that every port supports every advertised panel mode.
The difference can be substantial. MSI’s product page for the MAG 272UP QD-OLED X24 lists a 3840 × 2160 panel at 240 Hz, but describes console play over HDMI as supporting up to 4K at 120 Hz. That is a manufacturer specification for this model, not a general rule for all monitors. It demonstrates why the panel’s maximum refresh rate is not a guarantee that a console or every input can deliver the same rate.
Also check whether the monitor and source support the features you want to use together. Resolution, refresh rate, HDR, and VRR availability can depend on the specific combination of port, device, and mode. If the source reports a lower capability than expected, verify the selected input and the model’s port-specific specifications before changing picture settings.
Check the cable and port as part of that chain, but do not assume an upgrade is necessary. A different cable is worth considering only when the existing cable or connection cannot sustain the required signal. If your chosen input is limited to a particular mode, replacing a cable will not change that port’s specification. Likewise, a product page’s “HDMI 2.1” or high-refresh claim is not enough by itself: verify the actual modes and features listed for the precise model and input.
Set up a Windows 11 PC
Choose the correct input and display mode
- Connect the PC to the monitor input specified for the resolution and refresh rate you want. Check both the display’s port specifications and the graphics output limits of the PC; a high-refresh panel does not guarantee that every source-and-input combination can reach that rate.
- In Windows, open Settings > System > Display and select the HDR-capable monitor. Turn on HDR if the PC and display support it.
- Use the display and graphics settings available on your system to select a resolution and refresh rate supported by both the PC output and the chosen monitor input. If the target mode is missing, check the connection and model-specific input limits before assuming the monitor is faulty.
If you use more than one display, make sure you have selected the 4K OLED itself before enabling HDR or reviewing its available modes. A setting applied to a different connected display will not calibrate the OLED. After selecting the intended display, confirm the signal being sent rather than relying solely on the monitor’s advertised maximum refresh rate.
Calibrate HDR in Windows
For an external HDR monitor, Microsoft recommends using the Windows HDR Calibration app. Run it full screen and follow its three test patterns: they help set the point at which dark detail is no longer visible, the point at which bright detail becomes visible, and the display’s maximum brightness. Microsoft says the patterns are recommended by the HDR Gaming Interest Group (HGIG).
Rank #2
- 32" 4K UHD Glossy OLED Display - Experience ultra-sharp visuals and lifelike color on a stunning 32-inch 4K UHD (3840 x 2160) glossy OLED display. Every detail pops with depth and vibrancy, bringing your favorite games and content to life.
- Bright OLED Gaming - This UltraGear features Micro Lens Array+ technology. So with a typical brightness of 275 nits, this monitor is brighter than previous UltraGear OLED gaming displays and has improved viewing angles.
- VESA DisplayHDR True Black 400 & 1.5M:1 Contrast Ratio - VESA DisplayHDR True Black 400 certified with upt to DCI-P3 98.5% color gamut means this monitor meets industry standards for brightness as well as deep, rich black color expression. With a 1.5M:1 contrast ration, the benefit for gaming impeccable color and image detail in dark scenes for a stunning visual experience.
- 32" UHD OLED Brilliance with 165Hz of Game-Changing Speed - Experience ultra-smooth, tear-free gameplay with up to 165Hz on a bright 32” Glossy UHD OLED display. React instantly, spot every detail, and outpace your opponents in every frame with outrageous speed and clarity.
- Leave Lag Behind with 0.03ms Response Time - Enjoy smoother scenes with less lag or ghosting thanks to LG UltraGear OLED's nearly instantaneous 0.03ms (GtG) response time.
Work through all three patterns instead of skipping directly to a guessed peak-brightness number. The dark-detail test concerns the point where shadow information disappears; the bright-detail test helps identify the point where highlights become visible; the final test addresses the display’s maximum brightness. The prompts are intended to be judged on the connected display, so another monitor’s values are not a reliable substitute.
Windows also offers an SDR content brightness control for balancing SDR material while HDR is enabled. Microsoft notes that the balance depends on the display, so adjust it while viewing the content you care about instead of relying on a universal slider value. The HDR Calibration app’s SDR/HDR saturation slider is also subjective: Microsoft says its effect may be subtle and depends on display characteristics. Choose a position by appearance, not by copying a number from another monitor.
Finish with the game’s own HDR controls
Once the Windows display path is configured, use a game’s HDR calibration if it has one. Follow its on-screen instructions for the game’s own brightness or highlight controls. Those controls vary by title, so a setting that is appropriate in one game is not automatically right in another.
Do not treat the game’s calibration screen as a replacement for setting up Windows and the monitor first. Configure the display path, run Windows HDR Calibration, and then use the game’s test image or prompts. If you later change the monitor input, HDR mode, or system configuration, check the result again rather than assuming the previous game-specific values remain ideal.
Set up a PlayStation 5
Check what the console detects
- On PS5, open Settings > Screen and Video > Video Output.
- Choose Information for the Connected HDMI Device and inspect the reported resolution, VRR, and HDR capability. This is a useful first check when a mode or feature you expect is unavailable.
- Leave resolution on Automatic if you want the console to select the highest resolution the connected display supports. Sony describes the console as detecting the TV’s capabilities and automatically selecting the best available resolution.
That information screen is a practical way to separate a settings issue from a connection limit. If the capability listed by the PS5 does not match the monitor’s specifications, verify that the console is connected to the intended HDMI input and that the monitor is using the appropriate input mode, as described in its manual. Automatic resolution chooses among the capabilities the connected display reports; it cannot make an unsupported port or mode available.
Enable refresh-rate and variable-refresh features
Turn on 120 Hz Output if the display and game support it. Enable VRR for compatible displays and games. Sony cautions that results vary by display; if applying VRR to unsupported games causes unexpected behavior, you can turn off the option to apply VRR to unsupported games.
ALLM can switch the display to a low-latency mode automatically. Sony notes that VRR output can also cause low-latency mode even when ALLM is set to Off. These behaviors depend on the connected display, so check the monitor’s manual if the picture mode changes unexpectedly.
Rank #3
- 31.5" UHD (3840 x 2160) QD-OLED panel

- VESA DisplayHDR True Black 400 certified
- OLED Care 2.0 & MSI Gaming Intelligence AI
These features have different jobs. A 120 Hz output option concerns refresh rate, VRR concerns varying refresh output on supported combinations, and ALLM concerns automatic low-latency behavior. Enabling one does not mean every game will use all of them, and a monitor’s support for a feature does not guarantee that every console game supports it. If behavior is unexpected, test the game with the relevant optional VRR behavior disabled and compare.
Do these 3 things before closing this tab:
1Repair Windows errors before they cause bigger problems2Scan for outdated or missing drivers - takes under a minute3Clear out junk files and repair common Windows errorsChoose the HDR behavior you want
Set HDR to On When Supported if you want SDR games and apps to remain SDR. Always On converts non-HDR games and apps to HDR output instead. Use Adjust HDR and follow the on-screen prompts to set brightness; do not substitute a value from another display.
The choice is about output behavior, not a claim that one setting is best for every user. “On When Supported” preserves SDR output for SDR content, while “Always On” converts that content to HDR output. If you want to avoid that conversion, choose the former. In either case, follow the console’s Adjust HDR screens on the connected display.
Keep RGB Range at its default unless there is a specific problem
Sony advises leaving RGB Range unchanged unless an HDMI device sends range information incorrectly. Changing it without a matching problem can create a mismatch between the source and display, rather than improve the image.
What to check on Xbox and other consoles
Exact Xbox menu instructions are not established here, so use the console’s own display settings and reported capabilities rather than following an assumed menu path. First check the monitor manual for the selected HDMI input’s modes, then confirm which resolution, refresh rate, HDR, and VRR options the console reports for that connection.

Why your expected resolution or refresh rate may be missing
- The wrong input is selected: Check the monitor’s input selection and the port used by the source. Port capabilities may differ on the same display.
- The source or connection does not support the target mode: Compare the specific PC or console output with the monitor’s input specifications. Do not use the panel’s maximum refresh rate as a substitute for the port’s supported modes.
- The console reports fewer capabilities than expected: On PS5, revisit Settings > Screen and Video > Video Output > Information for the Connected HDMI Device. Compare the reported capabilities with the manual for the selected HDMI input.
- A game does not offer the desired mode: The game must support the feature as well as the source and display. In particular, Sony notes that VRR behavior varies by display and game support.
If these checks do not explain the limitation, consult the monitor manual and the source device’s support information for that exact connection. A cable change is relevant only if the existing cable or port cannot sustain the required signal; do not assume that buying an accessory will resolve a limitation elsewhere in the chain.
Fix 4K output flicker on PS5
If PS5 4K output flickers, Sony’s documented troubleshooting option is to reduce Video Transfer Rate to -1 or -2. These settings limit some output formats or refresh modes, so they are troubleshooting trade-offs rather than an automatic quality upgrade.
- Open Settings > Screen and Video > Video Output on PS5.
- Change Video Transfer Rate to -1 and check whether the flicker stops.
- If the problem continues, try -2.
- After changing the rate, verify which resolution and refresh mode remains active. A setting that stabilizes the signal may reduce the available output modes.
Because the transfer-rate options can limit output formats or refresh modes, confirm what signal remains active after applying one. If the display becomes stable but the console no longer outputs the mode you wanted, that is the documented trade-off, not necessarily a separate monitor fault. Return to the earlier value if the adjustment does not help and continue checking the connection and input capabilities.

Specifications help identify whether a monitor fits a particular setup, but they do not establish universal picture settings or independently measured gaming performance. The examples below are manufacturer-listed figures, accessed in 2026; the pages do not state their publication year.
| Example model | Manufacturer-listed resolution and refresh details | Console details listed | How to use the figures |
|---|---|---|---|
| MSI MAG 272UP QD-OLED X24 | 3840 × 2160; 240 Hz; 0.03 ms GtG; VESA DisplayHDR True Black 400 | Up to 4K at 120 Hz over HDMI for console play; the product page also lists VRR and ALLM for HDMI 2.1 console support | These are specifications for this cited model. The panel’s listed 240 Hz is not the same as its stated console HDMI limit. |
| Acer Predator CG48 | Up to 138 Hz on PC for specific supported models and connection conditions | Up to 4K at 120 Hz on PS5 and Xbox Series X for specific supported models and connection conditions | The page’s footnote scopes these modes to particular supported models and connection conditions; do not generalize them to every CG48 variant. |
For a purchase or compatibility decision, compare the exact model and region, the mode supported by each input, VRR and ALLM scope, HDR formats or certification, interface and cable requirements, OLED care features, and warranty terms. A listed certification or response-time figure is a product specification, not a substitute for checking the connection mode you intend to use.
In practical terms, start with the modes that matter to your devices: whether the intended input supports 4K at the refresh rate you need, and whether VRR or ALLM works with the source in question. Then check HDR specifications and calibration controls, followed by care features and warranty conditions. The cited MSI and Acer pages provide examples of manufacturer claims, not a ranking of the products or a guarantee of independent comparative performance.

When an image looks wrong, isolate the layer before changing multiple controls: confirm the input and signal mode, check the PC or console’s HDR state, then review the monitor’s own picture mode and the game’s calibration. Changing several layers at once makes it harder to identify which adjustment caused the result.
Frequently Asked Questions
What are the best settings for a 4K OLED gaming monitor?
There is no single OSD recipe that applies to every model. Confirm the chosen input supports the desired resolution and refresh rate, enable compatible VRR, calibrate HDR with Windows or console tools, and use the monitor manual for picture modes and OLED care controls.
How do I enable HDR and VRR on a 4K OLED monitor?
First confirm the monitor input and PC or console support the features together. In Windows 11, select the HDR-capable display under Settings > System > Display and turn on HDR; Microsoft recommends the Windows HDR Calibration app for an external HDR monitor. On PS5, inspect Settings > Screen and Video > Video Output and enable VRR for supported displays and games. Exact Xbox menu directions are not included here, so check the console’s reported capabilities and the monitor manual.
The Tool Desk
Outbyte Driver Updater FREEFix the driver behind crashes, sound loss and screen glitchesFind Drivers →Outbyte PC Repair FREERepair Windows errors before they cause bigger problemsFix Now →Should I use 120 Hz or the monitor’s maximum refresh rate?
Use the highest refresh rate that the source and the selected monitor input both support. A panel’s maximum does not guarantee that every input or console can deliver it: MSI lists 240 Hz for the MAG 272UP QD-OLED X24 panel, but describes console HDMI use up to 4K at 120 Hz.
Should PS5 HDR be set to “On When Supported” or “Always On”?
Choose “On When Supported” if you want SDR games and apps to remain SDR. “Always On” converts non-HDR games and apps to HDR output. Use the PS5 Adjust HDR prompts for brightness rather than copying values from another display.
Why is my PS5 4K output flickering?
Sony advises trying Video Transfer Rate at -1 or -2. These options can limit some output formats or refresh modes, so check which signal remains active afterward. Also verify that the PS5 is connected to the intended HDMI input and compare its reported capabilities with the monitor’s manual.
Should I change RGB Range on PS5?
Sony advises leaving RGB Range unchanged unless an HDMI device sends range information incorrectly. Changing it without a corresponding problem can create a source-and-display mismatch.
Do I need a new HDMI cable to get 4K at 120 Hz?
Not necessarily. Check the monitor’s exact input specifications and the console’s reported capabilities first. Consider a cable change only if the existing cable or port cannot sustain the required signal; a new cable cannot overcome a limitation in the monitor input or source.
Can I copy another monitor’s brightness or color settings?
No universal cross-model OSD values are established here. Windows SDR/HDR balance and saturation are display-dependent, while PS5 Adjust HDR and in-game calibration use their own prompts. Follow the exact monitor manual and calibrate on the display you use.
The Bottom Line
Start with the exact monitor input and confirm its supported modes, then select the highest resolution and refresh rate shared by the source and display. Enable VRR only where the connected device and game support it, calibrate HDR in Windows or on the console, and finish with any game-specific HDR prompts. Keep monitor OSD and OLED care choices model-specific. If PS5 4K output flickers, try Sony’s Video Transfer Rate -1 or -2 options and verify the output mode afterward.
