I am having some screen quality issues, aka fairy lights throughout the screen or random hot pixelation flashes and the occasional dead screen requiring a keyboard less restart by holding down the tower start button.
When the "pixelation" occurred I plugged the old screen in and could not see that screen have the same issues, but when I replugged the Samsung in it was fine too...??
However, when the Samsung was black with no response, as soon as I unplugged the monitor cable the screen showed the "no signal" alert. I then plugged the HP monitor in and it too showed black/blank.
I was able to get some details, I don't know if this helps, but I have copied and pasted from the unexpected shutdown notice:
