AIDA64 v8.20.8126 beta: SmartCool 2.1" LCD black after sleep/wake, hangs until USB replug

[PCLover420]

Hello,

I recently purchased a 2.1" LCD display from SmartCool that is designed to work with AIDA64.

The unit works correctly when it starts properly, but I am having a recurring issue:

• After I put my computer to sleep and wake it up, the LCD powers on but remains on a black screen.

• When I try to launch AIDA64 afterward to troubleshoot, AIDA64 stops responding / crashes.

Current workaround (temporary)

The only way I can get it working again is to:

1. Close AIDA64

2. Unplug the LCD display from the internal USB header

3. Reopen AIDA64

4. Plug the LCD back in

After that, the display starts working again.

My setup

• Windows 11

• AIDA64 v8.20.8126 beta

• LCD connected to internal USB header

• Motherboard: ASRock X470 Fatal1ty (if needed, I can provide exact model variant)

What I’ve already tried (no fix)

I have already tried the common troubleshooting steps suggested in forums and discussions, including:

• Closing any other LCD control software so only AIDA64 is running

• Disabling USB selective suspend in Windows power settings

• Disabling “Allow the computer to turn off this device to save power” for USB hubs in Device Manager

• Disabling Fast Startup in Windows

• Testing different USB header/port behavior (where possible)

• Reinstalling/relaunching AIDA64

• Using the beta version of AIDA64

I’ve seen that others have reported similar issues, but I haven’t found a confirmed fix yet.

If anyone has a solution (or specific settings in AIDA64 / BIOS / USB configuration that fixed this), I’d appreciate the help.

Thank you.
