Title: LCD Multisync no display
Post by: Amigamia on August 07, 2014, 04:26:28 AM
So I picked one of these neat looking monitor (http://www.tigerdirect.com/applications/SearchTools/item-details.asp?EdpNo=1263312)  for $25, hoping to get my AMiga 1000 back to life for a bit but I get nothing.

The monitor shows "Analog RGB - Out of Range" when I connect the VGA cable to one of those RGB->VGA adapter I bought from AmigaKit. I know the monitor works because I tested a laptop and I get life out of it.

I guess from the specs it doesn't go down to 15Khz but is there anything I can do to convert the signal maybe? What do you guys suggest? Do I keep it and try to make it work somehow or sell it back and get one that works?

You need a scandoubler, like the Indivision. There are different Indivision models depending on which Amiga you have: An ECS version, an A1200/A4000T version, and an A4000/CD32 version.

Here is a link to a scan doubler at AmigaKit. You need an adapter for the Amiga 1000 in addition though.

There are usally external box type scan doublers for sale on eBay as well.

Looking at the specs for the monitor on the page you linked it does 31.5 ~ 81.1kHz horizontal. So you are going to need a scandoubler/flickerfixer to use it on the 1000 via VGA unless the monitor has SVideo, which it doesn't mention.

Or send it back for a refund and get something that "syncs that low."

You can use an lcd television with SCART and an amiga RGB-> SCART adapter. It's fully RGB but the upscaler in lcd tv's aren't that good.
So perhaps an indivision or a decent rgb upscaler are better alternatives.  
Or, the best option:  
an arcade crt monitor (http://www.xgaming.com/store/arcade-parts-and-accessories/product/tri-mode-crt-arcade-monitor/)
