I'm back for yet more advice please..!!
A pal has a pc, perhaps 3 yrs old. The monitor suffered a fall, and is no longer useable. As a stop gap, I offered to donate an older monitor that I had sitting here. It has the correct connection, but doesn't display the desktop correctly.
Now, interestingly, when the pc is first powered up, the screen does display the pc manufacturers name, and the windows operating system correctly - all quite readable. But, when it goes through its start up routine, the screen just displays lots of colours which I think is the desktop; however it is totally unreadable.
Are different drivers required? I assumed that as it was just a change of monitor, it would be fine. Or is it like a printer, ie different printers require different drivers?
Could be difficult installing a new driver if I can't read what the screen says.
Any takers...?
