It seems to think I have HDMI ports. I can't find them on the case. There may be a chip on the board.

X blanked again this afternoon.
Code:
xset -display :0 dpms force on
didn't force it on.

Inxi can only work with whatever the kernel provides. At least 15 years ago Intel's chipsets quit "DVI" physical connector reporting, if they ever had it at all. I have a couple of old Intel boards with only DVI and VGA output connectors, but Linux reports HDMI and VGA. Electrically, DVI is HDMI, just without carrying sound output. I have a two year old Intel with the very same 4 physical output connectors, but Linux only sees DisplayPort and HDMI: kernel showing DVI and HDMI as HDMI, and DisplayPort and VGA as DisplayPort. The Xorg names reported by inxi vary according to which display driver is in use, having hyphens from the modesetting DIX, and no hyphens from the intel DDX.

On one of my test PCs I have almost the same GPU as you, but with physical outputs for DisplayPort, HDMI, DVI and VGA:

The 1920x1200 is on a HDMI-to-HDMI cable, but the 1680x1050 is on a DVI-to-DVI cable.

Today I repeated my test earlier today using a different DP cable. More than 3 hours after turning the display off I turned it back on, with everything found to behave normally.
