Integrated Graphics Driver Issue with KVM

[suthar0001]

The KVM switch never work with integrated graphics driver I have tested with many laptops different brands. Only duplicate screen mode work when asked for only secondary screen it goes black and white back and forth. Tried many things updating driver fully uninstalling the graphics driver and then installing it again, I am using HDMI cable for connection. Same KVM work without integrated graphics driver laptops. Its too much frustrating to have intel integrated graphics in laptops, specially for professionals like me who use multiple laptops with same hardware.

The quality of kvm switches vary widely, as well as the cabling.

Either try another switch, or better cables.

thanks AIHill,

If that is the case it should not work with all other laptops which do not have intel integrated graphis.

I have seen some very strange results with various kvm switches (I have four of them).  Do not dismiss this possibility.

Hello suthar0001,

Thank you for posting on the Intel Community Forum.

Thank you for reaching out and for providing the details regarding the issue you are experiencing with your KVM switch and Intel integrated graphics. I understand how important a stable multi-display setup is for your workflow, and I appreciate your efforts in troubleshooting the issue so far.

To help us better analyze the behavior and identify the root cause, could you please provide a few additional details:

• Could you share the make and model of the KVM switch you are using?
• What are the exact laptop models and Intel processor generations involved?
• Are you using any adapters or converters (for example, USB-C to HDMI), or is it a direct HDMI connection?
• What is the resolution and refresh rate configured when the issue occurs?
• Does the issue persist if you bypass the KVM switch and connect the display directly to the laptop?
• Have you tried using a different type of cable or interface, such as DisplayPort (if supported)?
• Could you confirm the graphics driver version currently installed on the system?
• When switching to “second screen only,” does the display show any image at all before flickering, or does it immediately start switching between black and white?
• SSU (System Support Utility) report 
• You can download the SSU tool using the link below: How to get the Intel® System Support Utility Logs on Windows*
