What does it mean when it says RAMDAC in graphics card specifications? It is always at 400MHz.

All your help is greatly appreciated.

RAMDAC = Random Access Memory Digital-to-Analog Converter.

Basically, this is the device that will convert the digital signal from your videocard/GPU to an analog signal that is then sent to your monitor via the standard 15-pin D-Sub analog connector.

Ah, I see. Why is set to 400MHz?

I get the fact that 400MHz is frame buffer rate and it allows the monitor to use certain refresh rates but why is set to 40MHz?

Is it for modern monitors to display higher refresh rates? Thanks.
