In #7, I listed four (4) methods that might assist the OP to remedy his illegible screen output.
I did not think of a 5th method until much, much later – sometimes even Wizards overlook the bleeding obvious
So without further ado, here is Method 0 (zero):
METHOD 0 (ZERO)
STEPS
8. In those settings, it may well be that the default highlighted is the one he does not want, that is 640x480. He can choose 800x600 and Apply it, he may be asked if he wants to keep that resolution, so choose to do so.
9. Reboot. If all has gone to plan, he will have a visible, legible screen, and can then work his way through those Display settings until he finds one that most closely reflects what he wants.
It should be noted that using xrandr in this way will, by itself, only last for the session you are in, hence having to continue to tweak the settings from the GUI, in order to have a lasting effect.
I will provide further options in subsequent Posts, likely daily for a few days, to assist Users in navigational directions.

METHOD 0 (ZERO)
STEPS
- Boot your PC
- At login, enter your password and press enter again
- If you are in the same sort of environment as the OP, you will be presented with an illegible screen (it may or may not have been preceded with a splash of coloured shapes). From here, we are working (effectively) “blind”.
- Press the Super key aka Windows key, usually between your left Ctrl button and left Alt button, often has a Windows logo on it. This will either open a Search field, or else open your Menu with a Search field activated.
- Type in (without the quotes) “terminal”. In Debian, this may offer a number of options including a multilingual terminal, but press Enter anyway. Now we are assuming we have an open Terminal.
- In the OP’s case, he has determined, as asked, from the output of “videoinfo” at bootup, that available resolutions include (but may not be limited to) : “1920x1440, 1600x1200, 1280x1024, 1024x768, 800x600, and 640x480”. He further volunteers “It is set at 640x480”, and “The manual for my Ultra VGA Monitor says that it can handle Resolutions up to 1024x768”.
At this point, he can type in and enter one of the other resolutions, let’s say 800x600. Command is as follows
Code:xrandr --fb 800x600
