I tried disabling the NVIDIA GPU in devmgmt.msc, and it worked. I don't know why, but it works even with NVIDIA GPU enabled now.
I've tried this just yesterday, but it didn't work at that time. I don't know why. Anyway, I will report more after testing further.

By the way, sometimes the monitor doesn't recognize that the USB cableis detached, and just keeps displaying the last input even if I turn it off and on again. Is it a bug or a hardware fault?

The Displaylink monitor no longer works since I rebooted my laptop.

What's the reason that the driver cannot support Optimus laptops?? :confused:

Hi,

Has the GPU that you previously disabled become enabled after the reboot?

Thanks,
James

Thanks for your reply.

Actually, I enabled it again before rebooting.

The strange thing is that disabling NVIDIA GPU sometimes makes the monitor work, but sometimes it doesn't have any effect. It seems like it depends on something else, too.
