How do I change the monitor model Windows 11 believes I have? Recently I replaced my monitor, but Windows 11 still shows the old monitor model in its Device Manager.

The monitor model listed in Windows 11 Device Manager does not match the actual model. When I connect the first monitor, Device Manager shows "Generic Monitor (TGCS-10)." When I connect a different monitor, it still shows "Generic Monitor (TGCS-10)." I need to uninstall the device with the incorrect name in Device Manager and reconnect the monitor to display the correct model. How could I make Device Manager automatically update to the correct model? Thanks.

The following is the PC information:

Toshiba 622536C

OS build: 26100.4770

Hello Ren,

Thank you for your post to the community.

Sounds like Windows 11 is clinging to old details as it is still identifying your new monitor as the old one.Here’s how to get Device Manager to recognize the correct monitor model:

Uninstall the old monitor entry:
- Open Device Manager.
- Expand Monitors.
- Right-click the one labeled Generic Monitor (TGCS-10) and choose Uninstall device.
- Confirm and restart your PC with the new monitor connected.
Force a driver refresh:

After reboot, Windows should detect the monitor and reinstall the driver.
If it still shows the wrong name, try manually updating:
Right-click the monitor in Device Manager > Update driver.
Choose Browse my computer > Let me pick from a list.
If your monitor’s INF driver file is available (from the manufacturer), point to it.

Kindly let me know how it goes .

Best Regards,

Hi James,

Thank you very much for your responses.

I have already requested the driver from the supplier and am currently waiting for their response.

Additionally, "Uninstall the old monitor entry" has proven to be effective.

Does this mean that, when replacing the monitor with a new one, I will need to manually uninstall the old monitor entry from Device Manager if it still appears?
