Another, cheaper, but less nice way to solve the problem is to go for the lowest common configuration.
Configure both your laptop and your CRT to sRGB. You can probably even do this without using software,
by using the color menu on your screen settings, and resetting that to default or sRGB if that is indicated separately.
This will probably mean reducing the quality of colors on your CRT, but your laptop most likely will be able to handle it.
Most contemporary LCD screens are set by default to sRGB, so this will also help you ensure that your art will look the
same to most other computer users.
