Monitor shows 'Input Not Supported' after driver update – fix

You just updated your graphics driver and now your monitor shows a black screen with the message “Input Not Supported.” That's frustrating. Don't panic, you didn't break your monitor. The fix is straightforward.

Step-by-step fix

1. Force shut down your PC. Hold the power button for 10 seconds until the computer turns off completely. After it shuts down, wait 5 seconds, then press the power button to start it again. As soon as you see the spinning dots (Windows loading logo), press and hold the power button again for 10 seconds to force another shutdown. Do this three times. On the fourth boot, Windows will say “Preparing Automatic Repair” and then show a blue screen with options.
2. On the Choose an option screen, click Troubleshoot.
3. Click Advanced options.
4. Click Startup Settings.
5. Click the Restart button in the bottom right corner. Your PC will restart and show a numbered list of options.
6. Press the 4 key or F4 key to select Enable Safe Mode. After you press it, Windows boots in Safe Mode with a very low resolution (usually 1024x768 or 800x600). Your monitor should show an image now.
7. Once you're on the desktop, right-click an empty spot on the desktop and select Display settings.
8. Under Display resolution, set it to your monitor's native resolution. For example, for a 1920x1080 monitor, pick 1920x1080. For a 2560x1440 monitor, pick 2560x1440. If you're not sure what your monitor's native resolution is, pick 1920x1080 – it's the most common and will work with almost any modern monitor.
9. Click Keep changes when prompted.
10. Reboot your PC normally (restart). Your monitor should now come back with a proper display.

Why this works

The “Input Not Supported” message means your monitor received a signal it can't display – typically a resolution, refresh rate, or timing it doesn't support. After a driver update, Windows sometimes defaults to a very high resolution or a refresh rate your monitor can't handle (like 4K at 120 Hz on an old 1080p 60 Hz monitor). Safe Mode forces Windows to use generic VGA drivers with a low, safe resolution. That bypasses the bad driver settings. Once you manually set the correct resolution, normal boot works fine.

Less common variations

You can't get into Safe Mode using the force-shutdown trick

If your PC boots too fast and the force-shutdown doesn't trigger the recovery screen, use a Windows installation USB. Boot from the USB, select your language, then click Repair your computer in the bottom left corner instead of Install. From there, go to Troubleshoot > Advanced options > Command Prompt and run this command:

bcdedit /set {default} safeboot minimal

Then type exit and reboot. Your PC will boot into Safe Mode automatically. After you fix the resolution, run the same command but with safeboot replaced with network or just type:

bcdedit /deletevalue {default} safeboot

That removes the Safe Mode flag so the next boot is normal.

The monitor has multiple inputs (HDMI, DisplayPort, DVI) and only one shows the error

If you're using an HDMI cable and the monitor says “Input Not Supported” but the DisplayPort works fine, the issue might be a handshake problem. Unplug the monitor from power for 60 seconds, then plug it back in. Also try a different cable. Cheap HDMI cables sometimes can't carry a high-bandwidth signal like 4K at 60 Hz. Use a certified HDMI 2.0 or DisplayPort 1.4 cable.

The error appears only when you wake your PC from sleep

This is usually a power management issue. Open Device Manager (right-click Start > Device Manager), expand Monitors, right-click your monitor model, select Properties, go to the Driver tab, click Update Driver, then Browse my computer for drivers, then Let me pick from a list. Choose the “Generic PnP Monitor” driver instead of the manufacturer-specific one. Reboot. That often fixes sleep/wake problems.

How to prevent this from happening again

Before updating your graphics driver, note your current resolution and refresh rate. Go to Display settings and write them down. Then when you update the driver, if the screen goes black, you already know what resolution to set in Safe Mode. Also:

• Use the manufacturer's driver update tool (NVIDIA GeForce Experience, AMD Adrenalin, Intel Driver & Support Assistant) rather than Windows Update. Those tools usually detect your monitor's capabilities and don't push unsupported settings.
• If you're using a secondary monitor that's older, plug it into a different port on your graphics card. Some older monitors don't support certain resolutions over HDMI but work fine over DVI or VGA.

That's it. The fix takes about 5 minutes. You don't need to reinstall Windows or buy a new monitor. Just Safe Mode, a resolution change, and you're back in business.
