If your Logitech G19 keyboard’s LCD is frozen on the logo or not working properly, don’t worry – I’ll show you how to fix it. The G19’s cool LCD screen should display useful info like system stats or game data, but sometimes it gets stuck.

Why Does This Happen?

Normally, your G19 LCD should:

1. Show the Logitech logo when you start your PC
2. Switch to your custom display once Windows loads
3. Let you use all the special G-keys and macros

When it’s not working right, you’ll notice:

• The LCD stays on the Logitech logo
• G-keys and macro keys stop working
• You can’t switch between hardware profiles

Summary

If the software is installed and you didn’t drop your G19 keyboard or worse – coffee spills then you should definitely try this first before anything else and especially before opening your G19 keyboard looking for hardware problems.

In Windows 11, open the Start Menu, type Windows Security, in Windows Security open Device Security then under Core Isolation click on Core isolation details then toggle off the Memory integrity option.
You will have to accept the settings and read why this might be a security problem with your Windows 11 PC. Do a restart and you have your LCD applets and macros working again. Enjoy!

Step-by-step Solution

If you’re running Windows 11 and your G19 LCD is stuck, try this first:

1. Open the Start Menu and type “Windows Security”
2. Open Windows Security and click “Device Security”
3. Under “Core Isolation”, click “Core isolation details”
4. Turn off “Memory integrity”
5. Accept the security warning (this does make your PC slightly less secure)
6. Restart your computer

Note: Only do this if you trust the software you’re running. It’s generally safe for home use.

Other Solutions to Try

Update Your Logitech Software

1. Make sure you’re using Logitech Gaming Software (LGS), not G Hub
2. Download the latest version from Logitech’s website
3. Install it and restart your PC

Reinstall the Keyboard Drivers

1. Press Win+X and select “Device Manager”
2. Find your G19 under “Keyboards”
3. Right-click and select “Uninstall device”
4. Unplug the keyboard, restart your PC, then plug it back in

Check for Hardware Issues

If you’ve tried everything above and it still doesn’t work:

1. Try the keyboard on another computer
2. Check if the USB cable is fully plugged in
3. If you’re comfortable, you can open the keyboard to check the LCD connection

When All Else Fails

If none of these solutions work, your keyboard might have a hardware problem. Before you give up:

• Contact Logitech support (even if it’s out of warranty)
• Check online forums for other solutions
• Consider buying a replacement if repairs aren’t practical

Remember: The Windows 11 memory integrity fix is the most common solution, so try that first before anything else.
