I was asked how resolution could be changed by using JUST the keyboard and not being able to see the screen since server 2003 was installed and used a higher resolution than the monitor supported.
Here’s the quickest way:
On a fresh boot, do this:
2.Press the letter ‘R’ for “Properties” (but I know you’re doing this blindly)
3.While holding down Ctrl, press Page Down exactly 4 times. Ctrl+Page Up and Page Down navigates through the tabs.
4.Now you are at the Settings tab. So try pressing the Left Arrow key a 1-2 times and then press Enter. This should reduce the resolution then pressing Enter is the same as clicking OK
If this doesn’t work, then start over and press Tab one time this time before using the Left Arrow key.
