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

http://www.amiga.org/forums/showthread.php?t=53866

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 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.


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.

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?
