I have an MSI GeForce GTX 1050 graphics card. I have 1 output HMDI to my TV, and 1 Display Port to my monitor.

For no obvious reason, I can no longer choose the HDMI as an output in windows. Under Display Settings, it won't recognize the HDMI display. It indicate I have only 1 display, not both.

Oddly, when my computer boots, it displays the BIOS info on the HDMI output (my TV). Then when Windows starts, it only shows on the display port and the HDMI signal is lost

What could have happened?

Thanks.
