Does anyone have a list of what LCDs will work on a IIgs?

Both of these people seem to have them on LCDs. Does a simple RGB to VGA (DB15 to VGA)plug converter work or is there more you have to do. Going to try the plug/converter on a few LCDs in the next few weeks.
Will report back.

A IIgs is not a Mac. They put out composite PAL/NTSC video don't they? Just use a cheap LCD TV

Well they put out both a composite and video to a DB 15 port. The main thing I have heard is the LCDs have to sync down to 15khz. If they can do that it should work.
These simple moulded adapter plugs for the Mac, that have DB15 on one end, and VGA on other should have the green sync up.
I have seen these with all kinds of switches on them. Have not investigated to what they do. Seems they have to do with the higher or lower numbers of the video display. That is to match video. Not sure how they do it.

Does anyone have a list of what LCDs will work on a IIgs? I can hook mine up to an LCD TV I bought specifically for the plethora of inputs it has. It's a small-ish Samsung widescreen that does 1400x900 resolution on my more modern PCs. Inputs include:
- * Component video
* Composite video
* SCART (into which I can pump analog RGB)
* S-Video
* VGA
With the GS, the composite looks fine for 40 columns, of course. 80 columns looks completely horrible, as also expected. I've tried various ways of getting at RGB, with no success so far:
- * The component video (Y'PbPr) would need a bunch of translation to work correctly
* I wired up a SCART connector for analog RGB, but one of the color pins (can't remember which... maybe red?) responds really weakly, so reds are almost too faint to see.
...and I know the RGB output of the GS is in good working order, because I have an Apple RGB monitor that looks gorgeous in 80 column mode. 🙂

That is what I wanted to know. How you would hook up the RGB and get the 80cols. If their was some easy ways. Such as the Mac to VDA adapter type plug.
Weak reds?

Mac to VDA adapter type plug. Do you mean VGA? That most certainly won't work. One would need an upscan-style converter. See: http://www.maricondo.org/
Weak reds? I dunno why that is - I suspect it's a failing of my Samsung.
