Apparently, there is a parallel interface on the SoC that can be used to drive VGA with hardware using a resistor ladder DAC. That’s native VGA at 1080p at 60 fps in addition to HDMI for the ...

The new dual monitor VGA adapter for the Raspberry Pi Model B+ has been ... The adapter uses a simple resistor ladder network as a digital-to-analogue converter, so the colour quality depends on ...

A bit of detective work revealed the display to be a 640×480 pixel mono VGA. The ‘Bone’s LVDS output can drive VGA through a resistor ladder DAC with the aid of an appropriate device tree ...

For such applications, a good choice would be a variable-gain amplifier (VGA) ... Combining them with a 15-step resistor ladder will result in a 4-bit digital potentiometer, ...
