RGB -> VGA Adaptor Help!
« on: July 06, 2006, 12:44:59 AM »
Hey guys, I just got an RGB to VGA adaptor, but when I turn on the 1200, the frequency is too low, so I can't change the screenmode settings. Is there a way to cycle the screenmodes by keyboard? Man I am so excited!

The big problem with those "silver box" adapters is that they often require the use of the internal scan-doubling circuitry on the AGA chipset or use super-high-res mode.  Either of those modes will suck the bandwidth out of the Chip Bus so that the graphics and sound updates will slow to a trickle.  If you're running only Chip RAM then EVERYTHING will slow to a trickle.  That's why a scandoubler is reccommended so highly for a classic Amiga (IF you're willing to go through with the expense).
