I have good results with the composite like the pic

[ATTACH]797[/ATTACH]

But my original question is about using the VGA in of the LCD TV. Just like a monitor.

(In the picture I was using a high standard composite cable; now I am using one that is even better and the results are better too)

there should be no (much) difference between SCART and VGA connector if its TV.
I would try connecting the RGB signals and see if it works. there have been reports that it does.

What model LG TV is that? Are you using composite output


No, RGB output from the Amiga. I believe the A500 composite output is in greyscale. This is an LG Flatron M237WDP but I think pretty much any model will do ok.

The VGA input is often handled by completely different circuitry in my experience. The SCART input can handle the Amiga video signal but it does not at all mean that the VGA input can too.

Sorry if I have muddled the topic a bit, with VGA only very few monitors will handle the Amiga modes :/ Someone on IRC mentioned that his Dell monitor can do it.

Well for one the RF output quality is pretty awful, and you'd need to switch between the inputs manually when you launch a game or such, so it's not very optimal. A TV with RGB SCART would be a good choice, but maybe not a possible one in Argentina...

Well, you would only use RF output for hardware-banging stuff ofcourse, there is no other way of getting this to display on LCD anyway (apart from getting an indivision). the VGA output is then used for productivity stuff using DBLPAL. Still worth a try IMO.
 
As for switching between inputs whenever you start a game - this is pretty common these days for Amiga users. I have my Bvision hooked up to the same monitor as my indivision,works pretty well but the switching is indeed manual labour. No problem though.

Well, indeed it is hard to get it the display on the LCD via the VGA input, since only very few monitors can handle the native modes - without knowing the exact model we can't know. But I was thinking his LCD TV might have either a SCART, s-video or component input (not sure what is prevalent in Argentina) in addition to VGA, which would all allow the modes to be displayed. SCART would do it directly or the other two via adapters. Any of them would be much nicer than the RF or composite output for sure. Of course, it may be a good idea to just save that money and consider an Indivision instead if VGA is a must.

Thanks for the advices. My LCD doesn't support SCART and s-video. The results using composite are really good (thanks to a very good cable), so I must consider buying an indivision internal scandoubler in the future to really improve the experience.

Its a fantastic device. So you could do worse than that :)
