Hello,

How can you check to see if monitor cable, adapter and VGA connections are working? New computer, old monitor. Monitor was working with older computor. Have a DVI-A adaptor connecting new cable to VGA monitor.

First boot the computer into "safe mode". (use F8 after you see the Windows logo) Safe mode will use a standard vga mode of 800x600 and 60 hertz. This should display on your old monitor. I suspect your default resolution settings on you new computer are out of the acceptable range of the old monitor.

Good Luck
Monitor is blank, no logo.

Then just keep pressing F8 after you turn on the computer.
If this works what should I set the default reslution to.

Just a guess 1024x768 works ok for most 15 to 17 inch CRTs
