DGamma allows you to change the apparent brightness response of your screen display. It can be used to correct for deficiencies in some monitors, or even if you just can't seem to get the colours right with those fiddly dials!

DGamma works by altering the colour look-up tables inside the video controller (VIDC) to resemble that of a gamma-curve rather than the usual diagonal line. It should be noted that other programs that try to reprogram the VIDC20 in the same way will not work in conjunction with DGamma.

DGamma is mode-independent. It will work in any screen depth and will not affect the current desktop palette.

Requires a VIDC20 video controller or compatible. This means any Risc PC or later machine.
