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

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.
