The Viao laptop screen is working fine.
When I went to the “system” on the control panel - it shows re: monitor: 4 or 5 “plug and play monitor” iistings??
Does that mean something?
I know the Dell monitor is getting power and I also know it is getting the laptop’s signal - because as I said it comes on every blue moon.
The other problem is that SONY loads the Vaio with tons of crapware so something might be fighting in the background. But I am still inclined to check if it is a hardware issue. I deleted, inactivated and removed most of the SONY crap so my machine runs fine.
