Wanting to make an Adapter to keep using my secondary monitor, a CRT at 1920x1440@75Hz
Is anyone hear familiar enough with ICs to make such an adapter?
RAMDAC would be an ADV7123 330MHz 10-bit RAMDAC.
I need a device which can accept GTF timings and drive the RAMDAC, options are:
1. ADV7619, which would require interleaving of or combining of the dual 24-bit busses (odd and even pixels)
2. STDP4020 hooked up (no idea how to, can't find detailed data sheets.)
not sure on how to hook up the ADV7619, I don't know how i can Interleave or Combine, and even if i could i have no idea how to hook up composite sync and blank signals to the ADV7123
this thread here may provide a bit of info that could be useful.
obviously if i need other ICs that is fine, just need to know what to drive the ADV7123 with, and what else is needed.
anyone know enough to help? this would allow up to 1920x1440@81-82Hz for a CRT Monitor, with the ADV7619 i know it could only do 8-bits per pixel, but better than nothing.
