I have a Viglen 486 laptop running DOS 6.22, OpenGem and Windows for workgroups 3.11.
Some of my Apps wouldn't work because I only had 16 colours. So I changed the resolution and colours in Windows Setup. Typical of me, I choose a setup that my LCD monitor, nor the monitor connected to it, supports. So, after the startup screen, everything goes black.
How can I undo this?
