Cooling Screen or Case Screen Not Showing, Frozen, or Stuck on the KOTIN Logo
This guide applies to KOTIN PCs with a liquid cooler screen or a case screen.
How the screen works
The cooling screen and case screen are not connected like a normal monitor. They do not use HDMI or DisplayPort. These screens are connected to the internal USB header at the bottom of the motherboard. The USB connection provides power and also allows Windows and the KOTIN screen software to send data to the screen. On some models, such as the G60B, the cooling screen and case screen may also connect through a small internal USB adapter board.

Common symptoms
If the screen stays on the KOTIN logo, shows a black screen, freezes, or only one screen works, it is usually caused by the KOTIN screen software not running, the software needing to be reinstalled, Windows not detecting the screen correctly, a loose internal USB cable, or a USB adapter board connection issue.
Step 1: Restart the PC
First, restart the PC and wait until Windows fully loads. It is normal for the screen to show the KOTIN logo during startup. The screen should start working after Windows and the KOTIN screen software load.
Step 2: Open the KOTIN screen software
After Windows starts, open the KOTIN screen software manually. If the screen starts working after opening the software, the screen itself is working normally. The issue was only that the software did not start automatically.
Step 3: Reinstall the KOTIN screen software
If opening the software does not fix the issue, please reinstall the KOTIN screen software. Uninstall the current KOTIN screen software first, restart the PC, then install the latest version from the official KOTIN download page. If Windows shows “Windows protected your PC,” click “More info,” then click “Run anyway.” Only do this if the file was downloaded from the official KOTIN website. After the installation is complete, restart the PC again and check the screen.
Step 4: Check the motherboard USB connection
If reinstalling the software still does not fix the issue, please check the internal USB connection. Turn off the PC and unplug the power cable first. Remove the side panel and look at the bottom area of the motherboard. The screen USB cable should be connected to the internal USB header near the bottom of the motherboard. In most cases, you do not need to remove the graphics card just to check the connection. You can usually look from the side and see whether the USB cable is loose, tilted, or not fully plugged in.
Step 5: Reconnect the USB cable if it is loose
If the USB cable looks loose or is not fully connected, it needs to be reconnected. We recommend removing the graphics card first before reconnecting the USB cable. This gives you more space and helps prevent damage to the USB header or the cable. Please follow our separate guide: “How to Remove and Reinstall the Graphics Card.” After removing the graphics card, gently plug the USB cable back into the motherboard USB header and make sure it is fully seated. Do not force the cable. The connector should line up correctly before you press it in. After that, reinstall the graphics card, plug the power cable back in, turn on the PC, and open the KOTIN screen software again.
Step 6: For G60B models, check the USB adapter board
For G60B models, there may be a small USB adapter board inside the PC. If the software has been reinstalled and the motherboard USB cable is connected properly, but the screen still does not work, please find the USB adapter board and switch the two screen USB connections on the adapter board. This means unplug the two screen USB cables from the adapter board and swap their positions. Then turn the PC back on, open the KOTIN screen software again, and check if the screen works. This can help when Windows detects one screen but not the other, or when the adapter board is not reading the screen correctly.
Step 7: Contact KOTIN support
If the screen still does not work after all the steps above, please contact KOTIN support. Please include your order number, your PC model, which screen is not working, a photo of the motherboard USB connection, a photo of the USB adapter board if your PC has one, and a short video showing the screen issue. This will help us confirm whether the issue is caused by software, the USB connection, the USB adapter board, or if a replacement part is needed.
