Apologies if the question doesn't make any sense. I'm self-taught and very new to Electrical Engineering.
I'm working on a little project with a DE1-SoC FPGA development board and found out that the video DAC (ADV7123) on the DE1-SoC has 3 10-bit colour channels. However, it seems like on the DE1-SoC board only 8 of the bits are connected to the FPGA itself and the two LSB of the colour information is tied to ground, as seen in this schematic:
If I understand this correctly, does this mean that it would be impossible to achieve full brightness on any of the colour channels, or is there some configuration specifically with the ADV7123 that allows it to achieve full brightness, even with two bits tied to ground?
