As a MS-DOS and VGA just didn&#8217;t have that issue.<\/p>\n<p>This isn&#8217;t a new trick and has done before. But here is some slight documentation. I used one of the scalers that are popular with us arcade people to scale the video to drive a VGA monitor. This is pretty well known, really the most limiting part is getting hold of DB-23 connectors. In my case I used a DB9 as the input so I could re-use the DB-23 to DB-9 monitor cable with the scaler. I have a plastic project box on order from eBay\/China to house the scaler and mount the connectors.  I was more than impressed by the output from the scaler board, it looks really good. <\/p>\n<p>Quick success and rapid turn around on this! <\/p>\n<p>If you want to do the same using the DB9, I used a DB9 male solder type D-SUB.<br \/>\nAlways check the pin labels on the plastic just to double check direction.<\/p>\n<p>Pin 1 = Black, GND<br \/>\nPin 3 = Red<br \/>\nPin 4 = Green<br \/>\nPin 5 = Blue<br \/>\nPin 7 = Grey = Sync<\/p>\n<p>The Yellow wire is not needed, no connection to the separate HS and VS pins on the scaler board.<\/p>\n<blockquote class=\"imgur-embed-pub\" lang=\"en\" data-id=\"a\/lkU6SAU\"><p><a href=\"https:\/\/imgur.com\/a\/lkU6SAU\">Amiga 2500 \/ scaler<\/a><\/p><\/blockquote>\n<p><script async src=\"\/\/s.imgur.com\/min\/embed.js\" charset=\"utf-8\"><\/script><\/p>\n","protected":false},"excerpt":{"rendered":"<p>The Commodore Amiga produces RGB video output @ 15khz.
