Product: HP Spectre x360 Convertible 15-bl0XX
Operating System: Microsoft Windows 10 (64-bit)

I've been using my laptop with a viewsonic projector for several years now, and for the last 3 days or so the HDMI connection will randomly drop (sometimes several times a minute), at which point the projector will search and re-detect the laptop within 1-2 seconds. 

 

I've tried switching to a different cable to no avail, and the same cable does not cause the connection to drop when using other inputs (like gaming systems, another laptop, etc). It does not seem to be a problem with the cable or projector. I have also updated the drivers on my graphics cards and performed a hard reset on the laptop with no change in the frequency of disconnects. Any guess what could be causing this? To my knowledge, there have been no updates or settings changes on either the laptop or projector preceding this problem. Below are my full device specs for the laptop.
