For the best starting setup, select your monitor’s native resolution and the highest refresh rate Windows offers at that resolution, enable VRR in both the monitor’s on-screen display and your GPU software, and turn on and calibrate HDR for HDR games. The exact options depend on the monitor, input, firmware, and graphics card, so confirm the supported modes in the model’s manual rather than relying on a universal preset.
Set the refresh rate at your monitor’s intended resolution
First confirm that the monitor, cable, graphics-card output, and selected input support the signal you want. There is no single cable specification that applies to every ultrawide OLED combination; use the monitor manual and GPU documentation for your exact models.

- In Windows, open Settings > System > Display > Advanced display and select the ultrawide monitor.
- Check the listed resolution, then choose the highest refresh rate offered at that resolution. An asterisk beside a rate can indicate it does not support the current resolution. See Microsoft’s Windows refresh-rate instructions.
- If you use NVIDIA graphics, the refresh-rate control is in NVIDIA Control Panel > Display > Change resolution. NVIDIA says a VRR-capable display will automatically use its highest refresh rate when VRR is enabled; check NVIDIA’s instructions.
The highest rate can vary by resolution and monitor mode. For example, an LG manual specifies different maximum rates for different resolutions and modes; those limits apply to that model, not to ultrawide OLEDs generally. Your PC may also render fewer frames than the display’s maximum refresh rate in a particular game.

Enable VRR in the monitor and GPU settings
Variable refresh rate (VRR) lets the display synchronize its refresh with the game’s rendered frame rate within a supported range. This can reduce or eliminate tearing and stuttering. The feature may be called Adaptive-Sync, FreeSync, or G-SYNC, depending on the monitor and GPU. Check the monitor’s OSD and the graphics software; enabling only one side may not be enough.

AMD graphics
Enable the monitor’s FreeSync or Adaptive-Sync option if required, then open AMD Software > Display and check FreeSync status and tier. AMD notes that certain monitor presets can disable FreeSync, so consult the monitor manual if the driver option is unavailable. Follow AMD’s FreeSync setup instructions.
NVIDIA graphics
In NVIDIA Control Panel, open Display > Set up G-SYNC, enable G-SYNC or G-SYNC Compatible for the supported display, and choose whether it should apply to full-screen or windowed-and-full-screen use. Make sure the monitor is selected and configured as needed. The exact options depend on the display. See NVIDIA’s G-SYNC setup instructions.
Low Framerate Compensation (LFC) can extend VRR below a display’s minimum refresh rate by showing duplicated frames. AMD illustrates this with a 60–144 Hz display syncing a 40 FPS game by doubling the displayed cadence to 80 Hz. It is an example of how LFC works, not a performance guarantee for every monitor or game. AMD’s FreeSync overview explains the feature.

Turn on and calibrate HDR for HDR content
Check that the monitor and game support HDR, then enable HDR for the correct display in Windows. Select the monitor’s HDR mode or profile according to its manual: presets and processing differ by model. Windows provides Windows HDR Calibration for setting the visibility of dark details, bright details, and maximum brightness. Microsoft’s HDR Calibration instructions describe the test patterns and setup.
- Calibrate in your normal room lighting and follow the test patterns on the HDR display.
- Set saturation conservatively; excessive saturation can make the image look unnatural.
- Display post-processing can interfere with calibration, so follow Microsoft’s guidance for the app and your monitor.
A product’s peak-brightness headline is not necessarily a brightness setting that the display can sustain across the whole screen. Manufacturers may report different figures for different picture conditions or illuminated areas; use the exact model’s documentation to interpret them.

If the OSD offers multiple presets, compare the actual modes rather than assuming one is best for every use. A preset can affect VRR availability or picture processing. Use the monitor’s manual and the relevant AMD or NVIDIA support page for compatibility details.

- How the selected mode behaves in your games, including whether flicker occurs.
VRR does not guarantee a completely flicker-free image in every game. LG’s owner’s manual says Adaptive-Sync/VRR can provide a clear screen without tearing or stuttering, while also warning that flicker may occur in some game environments. Treat that as model-specific guidance and check the manual for your display.
A model example is not a universal preset
The Philips 49M2C8900L/01 is specified as a 48.9-inch, 32:9 QD-OLED monitor with AMD FreeSync Premium Pro and NVIDIA G-SYNC compatibility. Those specifications describe that model alone; they do not establish which refresh, HDR, or VRR settings another ultrawide OLED should use. Check the exact monitor’s manual and supported modes.
