Set the foundation: native resolution and refresh rate
Use the panel’s native resolution first
Native resolution is the exact pixel grid the monitor was designed to display. It normally gives the sharpest image and avoids scaling artifacts. Dell notes that using a monitor’s native resolution is usually easier on the graphics card than selecting a higher resolution, which can also improve frame rate.

Ultrawide resolution is model-specific. A common 21:9 example is 3440×1440; the Gigabyte G34WQC2 manual documents that value for its panel. Do not assume every 34-inch monitor uses it: check the monitor’s specifications and Windows’ display settings. If your graphics card cannot sustain the native resolution in a demanding game, lower the game’s rendered resolution or use a supported upscaling mode while keeping the desktop at the panel’s native setting when practical.

An entry marked with an asterisk does not support the currently selected resolution. If the rate you expect is missing, select the native resolution first, then reopen the refresh-rate list. The available choices depend on the monitor, GPU output, cable, input port, and the display mode selected in the monitor’s on-screen menu.
You can also check NVIDIA Control Panel under Display > Change resolution. NVIDIA documents that a variable-refresh-rate display uses the highest rate automatically when VRR is enabled and the connection supports it. Confirm the selected resolution is under the PC section of the list rather than an incorrectly scaled television mode when both appear.
Enable variable refresh rate (FreeSync or G-SYNC)
What VRR changes
Variable refresh rate (VRR) lets the monitor alter its refresh timing to follow the frame rate being delivered. Microsoft describes AMD FreeSync, NVIDIA G-SYNC and VESA DisplayPort Adaptive-Sync as examples of this behavior. Matching refresh to frame delivery reduces visible tearing and can make uneven frame rates feel less juddery.

Enable both sides of the connection
- Open the monitor’s OSD and turn on its VRR option. The label may be Adaptive-Sync, FreeSync, or FreeSync Premium, depending on the model.
- For an AMD GPU, enable FreeSync in the AMD graphics software. For an NVIDIA GPU, open NVIDIA Control Panel > Display > Set up G-SYNC and enable G-SYNC or G-SYNC Compatible for the display if it is offered.
- Return to the game and verify that the game is using the ultrawide display, its native resolution, and the intended refresh rate.
NVIDIA defines G-SYNC as matching monitor refresh to GPU frame rate to reduce tearing, stutter, and input lag. Traditional V-Sync can add latency when the GPU waits for a fixed refresh interval, so use it only when you specifically prefer its behavior or when a game’s VRR implementation requires it. VRR still has a supported operating range; if frame rates fall outside that range, the monitor may use low-framerate compensation, fall back to a fixed rate, or show artifacts depending on the model.

Decide when HDR is appropriate
Check every required component
HDR is conditional, not a setting that improves every game or desktop. You need an HDR-capable monitor, an HDR-capable GPU and connection, an operating system that supports HDR, and a game with HDR support or a compatible Auto HDR path. In Windows, open Settings > System > Display, select the monitor, and look for the HDR control. If Windows does not identify the display as HDR-capable, check the monitor’s input mode and OSD before changing game settings.
Use native game HDR when available
For a game with its own HDR mode, enable it in the game and complete its HDR calibration screens. Those controls determine the paper-white level, peak brightness target, and shadow detail for that title; copying values from another monitor can make highlights clip or shadows look gray.
Do not leave HDR enabled simply because it is available. SDR desktop applications and games without proper HDR handling can appear washed out or excessively dim when Windows is converting their output. Switch between SDR and HDR based on the content you are using.

Understand Auto HDR and feature conflicts
Auto HDR is a Windows feature for supported SDR games; it is not a universal replacement for a game’s native HDR implementation. It still requires an HDR monitor and an HDR-capable device. The Gigabyte G34WQC2 manual documents one model-level interaction: PIP/PBP cannot be enabled while the monitor is receiving HDR and FreeSync signals. If an OSD option disappears, disable conflicting features one at a time rather than assuming the monitor is defective.

Optimize windowed and borderless games in Windows 11
Windows 11 includes Optimizations for windowed games for compatible DirectX 10 and DirectX 11 games running in windowed or borderless-windowed mode. Microsoft says the feature can improve performance, reduce frame latency, and expose Auto HDR and VRR on supported displays.
- Open Settings > System > Display > Graphics.
- Open Change default graphics settings and turn on Optimizations for windowed games.
- If the game is listed under the app options, select it and choose the preferred GPU and graphics setting.
- Restart the game. The change does not reliably apply to a session that was already running.
This setting does not convert every game to HDR, does not apply to every graphics API, and does not guarantee a higher frame rate. It is most relevant when you deliberately use borderless or windowed mode and the game meets the DirectX 10/11 compatibility requirement.
Tune the monitor’s gaming controls by purpose
Overdrive (response-time setting)
Overdrive changes how aggressively the LCD pixels transition between shades. A faster preset can reduce visible smearing, but an excessively strong preset creates bright or dark inverse trails around moving objects. Start with the middle setting, inspect motion in an actual game, and move one step up or down. The best choice changes with refresh rate because a setting that looks clean at 144 Hz may produce artifacts at 60 Hz.
Do these 3 things before closing this tab:
1Clear out junk files and repair common Windows errors2Scan for outdated or missing drivers - takes under a minute3Repair Windows errors before they cause bigger problemsMotion-blur reduction
Strobing or backlight-based blur reduction can improve clarity in fast games by flashing the backlight between refreshes. It often reduces brightness and may conflict with VRR. On the Gigabyte G34WQC2, the manual states that Aim Stabilizer Sync is unavailable below 100 Hz. If your frame rate regularly falls below the feature’s required rate, VRR is usually the more useful choice.

Black equalizer, gamma and brightness
Black equalizer lifts dark tones so enemies are easier to see in shadows, but too much makes the image gray and removes contrast. Set it only as high as needed for the game and room. Adjust brightness for your room lighting, then use gamma to correct midtone appearance; do not treat a value such as “50” as universal because OSD scales differ between models.
Sharpening and super resolution
Monitor sharpening and “Super Resolution” modes can make a lower-resolution render look crisper, but halos and ringing appear around text, fences, and high-contrast edges when the filter is too strong. Compare the feature at its neutral or lowest setting before increasing it, especially when the game already applies temporal upscaling or sharpening.
Display mode and picture presets
Picture presets can alter color temperature, gamma, brightness, and response behavior together. Use a neutral or standard preset as a baseline, then change one control at a time. The G34WQC2 manual also notes that its Display Mode is incompatible with FreeSync Premium and PIP/PBP, so a preset can remove access to features you expected to use.
Make ultrawide aspect ratio work in each game
A 21:9 or 32:9 panel does not guarantee full-width rendering. The game must support the aspect ratio, and some titles support ultrawide gameplay but keep menus, cutscenes, or competitive elements at 16:9. Others stretch a 16:9 image, crop the top and bottom, or add side bars.
- Set the game to the monitor’s native aspect ratio and resolution when those options are present.
- Check the game’s display menu for explicit 21:9, 32:9, ultrawide, field-of-view, or pillarbox controls.
- Inspect gameplay and menus separately; a correct gameplay image does not prove that every interface element is supported.
- If the image is stretched or cropped, use the game’s aspect-ratio control first. Change the monitor’s aspect-ratio mode only if the game provides no suitable option.
Competitive games may intentionally restrict the horizontal field of view for fairness. In that case, side bars or a centered 16:9 image can be expected behavior rather than a monitor fault.
Compare the settings that matter most
| Decision | Preferred starting point | What determines the result |
|---|---|---|
| Resolution | Monitor’s native value, such as 3440×1440 on the documented G34WQC2 | Panel specification, GPU performance, game render options |
| Refresh rate | Highest rate Windows offers at the selected resolution | Monitor mode, GPU output, cable, input port and connection bandwidth |
| VRR | Monitor VRR plus matching FreeSync or G-SYNC feature | GPU family, driver support, connection and the monitor’s VRR range |
| HDR | On for supported games after calibration; off for unsuitable SDR use | Monitor, device, Windows, game implementation and calibration |
| Motion clarity | Moderate overdrive; blur reduction only when its conditions suit you | Refresh rate, frame rate, brightness trade-off and inverse-ghosting artifacts |
| Aspect ratio | Native 21:9 or 32:9 when the game supports it | Game engine, menus, cutscenes and competitive restrictions |
Troubleshoot missing refresh rate, HDR or VRR
Change one variable at a time so you know which fix worked.
Quick Recap
- Confirm the Windows resolution: return to Settings > System > Display and select the monitor’s native resolution before checking refresh rate.
- Check the GPU output: verify that the cable is connected to the discrete GPU rather than a motherboard video output when your system has both.
- Try the other monitor input: the DisplayPort and HDMI inputs on a monitor can expose different combinations of refresh rate, HDR and VRR. Use the port specified by the monitor and GPU documentation.
- Inspect the cable: cable capability must be verified against the exact monitor and GPU; do not assume a cable supports a particular speed merely because its connector fits.
- Review the monitor OSD: turn on Adaptive-Sync or FreeSync, disable a conflicting preset, and check whether PIP/PBP or blur reduction is taking exclusive control.
- Recheck the GPU panel: enable the correct FreeSync or G-SYNC option after Windows recognizes the display, then restart the game.
- Test a simpler mode: temporarily disable HDR, PIP/PBP and motion-blur reduction. If the missing option returns, re-enable features individually to identify the conflict.
A practical setup sequence
- Install the current GPU driver and connect the monitor directly to the GPU.
- In Windows Display settings, select the monitor’s native resolution.
- In Advanced display, choose the highest refresh rate available for that resolution.
- Enable VRR in the monitor OSD and then enable FreeSync or G-SYNC in the GPU software.
- Launch a game that supports the ultrawide aspect ratio and select the native resolution.
- Enable the game’s native HDR and run its calibration only if Windows and the monitor report HDR support.
- For Windows 11 borderless or windowed DirectX 10/11 games, enable Optimizations for windowed games and restart the title.
- Set moderate overdrive, test motion, and adjust black equalizer, brightness, gamma and sharpening for your room and game.
- After every change, check for tearing, stutter, inverse ghosting, washed-out HDR, cropped edges and missing menus.
