Mark – I know what you mean about that stairstep. I have actually had my 2320 since December and my interlace screen still flickers badly. I have talk to tech about it, sent the card back, and have tryed another card – all to no avail. However, just yesterday I figured out what the problem was. Apparently I never read paragraph # 7 on page 18! There it mentions a jumper on the mother board (J300) that should be set from the factory in the left had postition. It has to do with the timing to the CIA chip. With the jumper in the left postition it will take its timing from the AC Freq. but in the right postition it takes its time base from the Vertical Sync. The A2320 needs it to be in the left. I don't know what factory put my CPU together cause when I pulled the Power Supply to check the jumper sure enough it was in the wrong position. I just changed that jumper and all my Flickering went away. Now, finially I have a the display I have have wanted since getting this card and monitor combo in DECEMBER! Now that I am flicker free, I can live with the other problems. I will have my tech do the fix for the 07 and 08 problem. –> "The fix can even be as simple as soldering the 33 ohm resistor packs on the back of the A2320 pcb to the existing 180 ohm reistor pack (RP301, RP302, RP303 on the pcb silkscreen) which results in the 33 ohm being in parallel with the 180 ohm resistor pack and is A-OK. This is about a five miniute job." Thanks Mark for you comments – if only FF lowered there price a long time ago, we'd have alot more people out there with Flicker Free displays. – Roy Pahnke – 1.800.76.AMIGA – Crazy Mountain Software – Casper Wyomin'
