Title: Scan Doublers
Post by: zizban on January 15, 2008, 05:09:32 PM
I have been looking around for a scan doubler for my A1200 so I can hook it up to a monitor. I've seen Eyetech EZVGA mentioned. Anyone have any suggestions?

My suggestion: Forget it.
Longer version: I don't know anyone who has any in stock,
and the last one I saw on eBay went for £131. Yes, that's
~USD 238, ~EUR 164! Crazy, eh?

Ok. That wasn't a very helpful answer. Where do you live?
If you have PAL, use LCD TV instead. There are also supposed
to be some monitors that can sync down to Amiga modes,
but I haven't tried any. Perhaps someone who has tried
any of these can suggest one?

If you really want to shell out for a ScanDoubler on eBay,
be aware that some of them can't display the full AGA
palette in your A1200, meaning bleaker colours. If this
matters to you, check Amiga Hardware Database (http://amiga.resource.cx/), or
Big Book of Amiga Hardware (http://amigahardware.mariomisic.de/index_e.html) before placing your bid.

I live in the US. I was debating getting my A1200 up and running or getting an Efika and praying for Morphos.

Not in the USA!

Look at this thread from last week:
http://www.amiga.org/forums/showthread.php?t=33755

or another from the week before that:
http://www.amiga.org/forums/showthread.php?t=33584

Basically, we are screwed as far as finding a LCD that will accept Amiga RGB in the US.

Well, you can cross your fingers and wait for this one (http://www.amiga.org/forums/showthread.php?t=47197).  Looks really promising, let's just hope it finds its way into the production line ASAP :-)

I have a question for you USA folks, what kind of connectivity do you have on a modern TV? CVBS, s-video, component??

If you have component connectors, you'll have to look for an RGB -> component converter (if such a beast exists)

It does exist :D

I found a DIY one

Generally S-Video and Component.

Component is indeed our best option here, without spending ridiculous $$$. Couple of small issues though:

1. The RGB -> Component conversion -- I tried one of the popular options known as the JROK, with completely unsatisfactory results. There are other options though, and a fellow here in the States makes an Amiga-specific one which should work OK.

2. Finding an LCD that deinterlaces and displays PAL screens properly. (I tried a Sharp Aquos that flicker-fixed laced modes, yet PAL screens were distorted despite its being advertised as PAL/NTSC/SECAM compatible. The Samsung 171MP handles standard non-laced NTSC modes beautifully, but doesn't deinterlace or display PAL screens correctly.)

3. In the event you find a multi-region LCD, there's a good chance it dithers/doesn't handle 24-bit color (another reference to my Aquos, while the Samsung handles color fine with no dithering)... and there are few EDTV/HDTV CRT's out there which aren't huge (I prefer smallish screens, anything larger than 17" and amiga games/demos look ridiculously pixelated to me).


Next step for me is to pick up a *working* RGB -> Component adapter, and continue looking for a good multi-system LCD. (A 24-bit scandoubler would really solve a lot of these issues, LOL.) At this point I would settle for something which simply handles PAL/NTSC non-interlaced modes perfectly... flicker free laced screens sure are nicer for WB usage though.

Or find someone to, ah, 'bring' in already working LCD's from Europe in their luggage  8-)
