Hi - I found this user's solution on the internet. I don't know if it would work for you but worth a try.
Hi folks,
I had this problem with my monitor: after boot, monitor comes on for just about 1-2 seconds then goes
to black.
SOLUTION: Mine was solved by changing the display color quality from high (32-bit) to medium (16-bit).
(YES, I had to repeatedly hit the monitor button and quickly move the mouse to do these steps, which was quite challenging)
ALT-CLICK on a blank spot of the desktop; from the dropdown menu, choose PROPERTIES.
Click on the SETTINGS tab, where you'll see COLOR QUALITY dropdown box. Mine was set to High (32-bit).
I clicked on the dropdown arrow and chose MEDIUM (16-bit), and this solved my problem.
Hope it solves yours!
