A4K simply refuses to output to a PC monitor

Dandelion ... keep your hair , bet you look good with it...
  vga and svga  sync. to 37htz and up ...  the cbyerstorm bd will /with the cyberstorm lib. will create the solution for you...
 I had both a 3000Tower and a 4000Tower , the 4000Tower was never up to the 3000T.. even with both of them having a warp engines  and cybergraphics / storm board(s)...the RTG boards enable you to have a multisync and multiscan  without that troublesome doubler... I hooked up a 21" Nokia 445 monitor..with a dot pitch of .22 and ran the output up to 110htz@1600x1600 resolution ... talk about a Beautiful screen... and a hell of a refresh rate ...

 I forgot some details since this was all back in '94 and I have 'part-timers' disease ...lol..  but try a cyberstorm , which i gather you want or have and the lastest update cybervision libraries .. I used a five lead output cable to the monitor .. its better than a composite cable.......... five leads are(bk, gy, yellow, blu,cyan ... have the cable  made if you have to ... you can't beat the fabulous color you can tweak your monitor... have fun .... I'm sure the newer techie here can explain it better than I ...good luck.. :python:

dandelion ..PS: about the 4000 differing from 1200 ... that has to do with video card differences via aga  on the 2 entirely different outputs ... thats why 1200 folks go to tower boxes for extra cards and excellerators ..more power .. btw... make sure all your scsi cards are the lastest and will address the support for SVGA monitors ... OR    try a special monitor that will multi sync/scan from 15htz to 75 or more .. I forgot the name of the japanese company that makes that monitor... couldn't spell it anyhow ... but they are fairly common with 3D rendering people...and video toaster folks ...   basically what you are doing is bypassing the AGA chipset and going with a accellerator that supports a HIRES monitior with Mutisync AND Multiscan ... read my other post also ...
