Fix Blurry or Shimmering Graphics in Switch 2 Games

If your Nintendo Switch 2 games look soft, pixelated, or have distracting flickering edges, this guide walks you through the most effective fixes. We’ll cover system-level settings, in-game options, and display-side adjustments to get you the crispest image possible.

What You’ll Need

• Your Nintendo Switch 2 console and its dock (if playing on a TV)
• The game that’s showing issues
• Access to the System Settings menu
• Your TV or monitor’s remote or on-screen menu
• An HDMI cable (the one that came with the console is best)

Step-by-Step

1. Check Your TV’s Display Mode

Many TVs apply extra processing that can make games look worse. Look for a “Game Mode” or “PC Mode” in your TV’s picture settings. This reduces input lag and disables motion smoothing and edge enhancement that cause shimmering. Enable it for the HDMI port your Switch 2 is connected to.

2. Set the Console’s Output Resolution

Go to System Settings → TV Settings → Resolution. Choose the option that matches your TV’s native resolution. If you have a 4K TV, select 4K. If you have a 1080p TV, select 1080p. Using a lower resolution than your TV’s native can cause upscaling blur, while using a higher one on a 1080p TV can cause downscaling artifacts.

3. Adjust the RGB Range

In the same TV Settings menu, find RGB Range. Set it to Full if your TV supports it (most modern TVs do), or Limited if you notice crushed blacks or washed-out colors. A mismatch here can cause banding and shimmering in gradients.

4. Turn Off the Console’s Sharpening (if available)

Some Switch 2 models or firmware versions have a sharpness slider. If you see one under TV Settings, set it to 0. Artificial sharpening adds white outlines around objects, which is a common cause of shimmering in motion.

5. In-Game Graphics Settings

Open your game’s options menu. Look for settings like:

• Resolution Mode – prefer a “Quality” or “Resolution” mode over “Performance” or “Framerate” if you want sharper textures.
• Anti-Aliasing – set to High or On if available. This smooths jagged edges.
• Motion Blur – turn it off. It can make the image look blurry during camera movement.
• Dynamic Resolution – disable it if the game allows. This stops the game from lowering resolution on the fly to keep framerate, which causes sudden blurriness.

6. Update the Game and System

Game developers often release patches that fix rendering issues. Check for updates by highlighting the game icon on the Home menu, pressing the + button, and selecting Software Update → Via the Internet. Also ensure your Switch 2 system is up to date under System Settings → System → System Update.

7. Restart the Console

Sometimes a simple reboot clears temporary glitches. Hold the power button on the console, select Power Options → Restart. This can resolve GPU memory leaks that cause texture shimmering.

8. Try a Different HDMI Port or Cable

A faulty HDMI cable or a port that doesn’t support the required bandwidth can cause visual artifacts. Try the second HDMI port on your TV (often labeled HDMI 2.0 or 2.1). If you have another high-speed HDMI cable, swap it in.

Common Mistakes

• Forgetting to enable Game Mode after a TV firmware update – updates can reset your picture settings.
• Setting the console to 4K on a 1080p TV – this forces the TV to downscale, which can look blurrier than native 1080p.
• Leaving motion smoothing on – this is a TV feature that tries to interpolate frames, causing a “soap opera” effect and shimmering around moving objects.
• Ignoring in-game sharpness sliders – some games have their own sharpening that stacks with the TV’s, making things worse.
• Using a low-quality HDMI cable – older or damaged cables can cause sparkles and flickering.

Tips

• If your TV has a “PC” or “Monitor” input label, use that for your Switch 2. It often disables extra processing automatically.
• For handheld play, the screen’s sharpness is fixed, so ensure your console’s screen is clean – smudges can make the image look blurry.
• Some games have a “Reinstall” option in the menu. If a game’s files are corrupted, a reinstall can fix texture issues.
• Check if your TV has a “HDMI Black Level” setting that matches the console’s RGB range – they must match.

Troubleshooting

If you’ve tried the steps above and still see issues:

• Test another game – if only one game is affected, the problem is likely in that game’s code, not your setup. Check for a patch or community workarounds.
• Test on another TV or monitor – this isolates whether the issue is your TV or the console.
• Reset your TV’s picture settings – go to the TV’s menu and choose “Reset” or “Default” for that input.
• Try a different power outlet – electrical interference can sometimes cause visual glitches, though it’s rare.
• Contact Nintendo Support – if the issue persists across all games and displays, it may be a hardware fault with the GPU. They can advise on repair options.

Frequently Asked Questions

Why does the image look blurry only when I move the camera?

This is usually caused by motion blur being enabled in-game, or by your TV’s motion smoothing. Turn off motion blur in the game and enable Game Mode on the TV to fix it.

What does “shimmering” look like?

Shimmering appears as tiny flickering or sparkling pixels on edges of objects, especially in high-contrast areas like railings or foliage. It’s often caused by aliasing and sharpening.

Is it better to play in 1080p or 4K on a 4K TV?

If your TV is 4K, set the console to 4K and let the game render at its native resolution. If the game runs at 1080p internally, the TV will upscale it, which is usually fine. Avoid setting the console to 1080p on a 4K TV because that forces the TV to do a lower-quality upscale.

Can a bad HDMI cable cause shimmering?

Yes. A cable that doesn’t have enough bandwidth or is damaged can cause pixel sparkles, flickering, and even random blackouts. Use the included cable or a certified high-speed one.

Will turning off the console’s sharpening make the image too soft?

No. Sharpening adds artificial contrast to edges, which can make the image look crisp but also causes halos and shimmer. Turning it off usually reveals the true, cleaner image. If it looks too soft, adjust the TV’s sharpness to a low value instead.

Does the Switch 2 have a built-in upscaler?

The Switch 2 includes hardware upscaling for games that support it. If a game doesn’t use it, the console will output at a lower resolution and rely on the TV’s upscaler. In that case, make sure your TV’s sharpness is set to 0 and Game Mode is on.
