Summary: Text looks fuzzy or apps are blurry on Windows 11? Set native resolution, fix display scaling, tune ClearType, override DPI per app, and fix TVs used as monitors.
Recommended app: PC-Troubleshooter — https://www.mytechnician.tech/apps/windows-troubleshooter/ (Microsoft Store: https://apps.microsoft.com/detail/9N7RWKW8SP24?hl=en-us&cid=mytechnician-web). Optional; every step below uses built-in Windows tools.

## The Problem
Everything on screen looks slightly soft, as if it has been smeared. Or most of Windows is sharp but a few apps are fuzzy. Or the whole desktop is too big, stretched, or has black bars at the sides.

Nearly all of these trace back to one of three causes: the display is not running at its **native resolution**, Windows **scaling** is fighting an older app, or — on a TV — the picture is being processed as video instead of as a computer signal.

> **Screen flickers or goes black rather than blurry?** See [fix screen flickering](https://www.mytechnician.tech/tips/fix-screen-flickering-flashing-windows-11/) or [second monitor not detected](https://www.mytechnician.tech/tips/fix-second-monitor-not-detected-windows-11/).

## Symptoms
* All text is fuzzy on every app, including the Start menu.
* Only some apps (often older installers, utilities, or games launchers) are blurry.
* Text went blurry after connecting or disconnecting an external monitor.
* A TV used as a monitor has soft text and coloured fringes around letters.

## Quick Checks
1. Restart the PC. Apps that were open when you changed monitors keep the old scaling until they restart.
2. Make sure the cable goes into the **graphics card**, not the motherboard, on a desktop with a dedicated GPU.
3. Press the monitor's **Menu** button and look for a **Sharpness** setting. Leave it at the default (often 50 or the middle); very low values blur text.

## The Fix: Step-by-Step

### Step 1: Set the Native Resolution
LCD screens are only sharp at one resolution. Anything else is scaled and blurred.

1. **Settings** → **System** → **Display**.
2. Select the monitor at the top if you have more than one.
3. Under **Display resolution**, choose the option marked **(Recommended)**.

If **Recommended** is not the resolution printed on the monitor's box (for example, it offers 1920 × 1080 on a 2560 × 1440 screen), Windows does not know what the monitor can do. That is almost always a missing graphics driver — go to Step 5 — or a cable that cannot carry the resolution.

### Step 2: Use a Standard Scale Setting
Scaling makes things bigger on high-resolution screens. It works best at the recommended value and at whole steps.

1. **Settings** → **System** → **Display** → **Scale**.
2. Choose the **(Recommended)** value, or 100%, 125%, 150%, 175%, or 200%.
3. If you previously typed a **Custom scaling** value, remove it: **Scale** → **Custom scaling** → **Turn off custom scaling and sign out**. Custom values are the main cause of Windows-wide blur.

### Step 3: Let Windows Fix Blurry Apps
When you move between monitors with different scale settings, older apps are stretched as a bitmap instead of redrawn.

1. **Settings** → **System** → **Display** → **Scale** (click the arrow) → turn on **Let Windows try to fix apps so they're not blurry**.
2. Sign out and back in.

### Step 4: Override DPI Scaling for One App
If one specific program is still blurry:

1. Right-click the program's shortcut or `.exe` → **Properties** → **Compatibility** → **Change high DPI settings**.
2. Tick **Override high DPI scaling behavior** and choose:
   * **Application** — the app draws itself; sharpest, but some text may be tiny.
   * **System (Enhanced)** — Windows redraws text sharply; works for many older desktop apps.
   * **System** — the default blurry stretch; only useful if the other two break the layout.
3. Click **OK** and restart the app.

### Step 5: Install the Proper Graphics Driver
If Device Manager shows **Microsoft Basic Display Adapter** under **Display adapters**, Windows is using a fallback driver that supports only a few resolutions.

1. Download the driver from **NVIDIA**, **AMD**, **Intel**, or your laptop manufacturer.
2. Install it and restart. The native resolution should now appear as **Recommended**.

See [how to update outdated drivers](https://www.mytechnician.tech/tips/how-to-update-outdated-drivers/) if you are not sure which GPU you have.

### Step 6: Tune ClearType
ClearType smooths text for your specific panel. The default is tuned for a standard monitor and can look fuzzy on others.

1. Press `Win + R`, type `cttune`, and press Enter.
2. Tick **Turn on ClearType** → **Next**, and pick the sharpest sample on each page.
3. On multiple monitors, the tuner runs once per display.

### Step 7: Fix a TV Used as a Monitor
TVs process the signal for film and often crop the edges (overscan) and compress colour, which blurs small text.

1. On the TV, rename the HDMI input to **PC** or switch the picture mode to **PC** or **Game**. This turns off sharpening and processing on most brands.
2. Turn off overscan: look for **Picture size**, **Screen fit**, **Just scan**, or **1:1 pixel mapping**.
3. In **NVIDIA Control Panel** → **Change resolution**, set **Output color format** to **RGB** and **Output dynamic range** to **Full**. In **AMD Software** → **Display**, set **Pixel Format** to **RGB 4:4:4 Full RGB**. This removes the coloured fringes caused by chroma subsampling (4:2:0).

## What Not to Do
* **Don't use custom scaling values** like 112% or 133%. They blur apps and leave some UI at the wrong size.
* **Don't run a lower resolution to make things bigger.** Use Scale instead — lower resolutions are always blurry on an LCD.
* **Don't turn monitor sharpness to maximum.** It adds white halos around text rather than making it clearer.

## Still Not Working?
If the native resolution is missing even with the correct driver, try a different cable and port — an old HDMI cable or a passive adapter can limit the resolution. If you also want the monitor's full refresh rate, see [fix a monitor stuck at 60 Hz](https://www.mytechnician.tech/tips/fix-monitor-stuck-at-60hz-windows-11/), which covers cable and port limits in detail.
