For expereinced computer users it is very easy to find out the manufacturer and model of the VGA adapter - but may even then sometimes one can run into troubles to find the exact match.
This here shall be a very easy step to do this using Debug which comes with Windows and can be accessed from within Windows or from the command prompt or DOS PROMPT - the outcome will always be the same
Open debug either from the Run command line (use Browse to locate it)or by typing DEBUG at the command prompt
YOu will see a flashing cursor there just type in the following code and then press enter - on the right side of the screen you will see all or most the info you are looking for - entering ..
Example
-D C000:0 and press enter will reveal the VGA adpater installed into the computer.
-d again will let you see more data - for some VGA adapters there it may be necessary to repeat this several times..
To quit DEBUG use Q and enter.
