HDMI port problem
 

My HDMI port stopped working today on my month-old laptop. It sort of freaked out, audio disconnect/reconnect notices and flickering screen for about a minute, and then nothing. I have tried all the common thing, so cord works elsewhere, problem across multiple displays, software/drivers/OS updated, rebooted laptop, Win 10 diagnostic tool, etc.

I did see that the computer knows it is connected to a display when the HDMI cord is plugged in and I can drag things to the expanded display, but no audio/video signal makes it there.

Is there anything else I can try?

Did you check Display settings to see if the laptop is recognizing the monitor as connected? Some laptops make you do a button press (like Alt/F7) to swap to an external monitor; could that be it?

Yeah, tried that. It shows the screen there, and I can drag windows on to it. It is there, but I can no longer see (or hear) it.

Did you check the input on the monitor (assuming it has more than one HDMI In)?

Yeah, and the monitor works fine with another laptop. The same HDMI problem occurs across multiple displays that it used to work on, too.

You might try to update your video drivers. Something could have gotten corrupted.

I tried that, too. Seems it was simply the HDMI port failed and Asus is covering it under warranty.

Thanks all.
