LCD and RGB-VGA adapter

[Guille64]

Hello,
I wonder if it is possible to use my LCD tv (which has a VGA socket) in combination with the RGB-VGA adapter and...
Replace (or almost do that) the Amiga monitor which I don't have anymore.
I don't know if the LCD is Multisync and don't have the adapter, so, before buying it I prefere to ask you about this.

Thank you all!

sadly unlikely to work - the common 23-15 pin adaptor is just that.. a pin adaptor.. and will use 15(something) which standard vga and your tele will not take (wants 30+

cant remember exact Hz levels without getting out of the sofa :/

You need a scan-doubler

It depends on the make/model of the TV or Monitor.
I have some lcd monitors that can handle 15Khz (NEC AccuSync LCD 51v), but most will not.

Same story with lcd tv's, some will, some won't.

My 19" JVC LCD TV works with a standard VGA-RGB adapter so I guess its just a case of try and see

A similar discussion was going on in this thread...

This seems to be a reoccurring topic. In my opinion it is an important topic for both new and old Amiga users alike. It would be great if LCDs which work could be compiled into a database or perhaps the super cool awesome spectacular (Note: gratuitous praise intended) moderators here at A.org could make a sticky thread.

I would envision something like the following...

Manufacturer:
Type: LCD, Plasma, LED, etc.
Size:
Mfg Model Number:
Amiga video modes confirmed:

I am sure that the best and quick way to find out the possibilities of vga adapters on lcd's is just testing them.
But it's 20 pounds to put an adapter in Argentina and it is 1/5 of the scandoubler after all.
I have a Samsung 32" series 4. I will look at the manual to find some clues...

Good idea Ed.  I would suggest adding the years of manufacture to LCD monitors that are no longer in production and the word "Current", or something like that to indicate that the monitor is still being produced.

I dont get it. Cant you just hook the RF output up to the tv for configuring and playing games and such, and hook up the RGB port of your Amiga to the VGA input on the tv, and use a DBLPAL driver for your workbench? I guess Im missing something, its been 15 years ago.

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...

I think this also falls in to the category of possible but with what hardware?

In my experience of trying to use the RF input, S-Video or Composite input with my various TVs the displayed image often looks pretty poor. I believe that even with the SCART input that the good folks in Europe have, that a there are LCD TVs that either work, partially work, or don't work at all.

Someone more knowledgeable that I would need to comment on using DBLPAL or DBLNTSC, but it seems to me that this might work with the VGA input on some LCD TVs and not with others. I believe that DBLPAL runs at 27.5Khz as opposed to standard VGA which is 31KHz.

Depending on the model you could also use the composite out (A600/1200) or the composite out of an A520 modulator.

As the previous poster said, SCART would be the ideal way if it were available on your TV (unlikely though).

Alternatively, there was a Amiga RGB > S-Video adapter project going on over at EAB - you may want to check in there on the status of the project (ask Zetro).

In my experience even dblpal modes are often out of range on most monitors - just under 31kHz iirc.

Just found the relevant thread.

It seems that AmigaManiac is building/selling these.

They're available from his website.

Here's what the output of an A500 looks like on my LCD TV. JPEG compression on the photo is pretty heavy but the output is quite sharp and very stable. S-video should be reasonably close if it's a good converter.

@ajk

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

I have good results with the composite like the pic

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)
