I recently acquired an LC III that's in very good condition. Unfortunately, I don't own a vintage Apple CRT so I don't know if I'm experiencing a problem or if I just have a slightly incompatible monitor. As you can see here the video display is pinkish: http://i.imgur.com/QrO8YuD.jpg

I'm using an adapter that I had with my Power Macintosh G3 (Beige), it works fine on that machine along with that same LCD monitor. Adapter pictured here connected to the LC: http://i.imgur.com/WVBBEbu.jpg

I have experience recapping, so that's not an issue if it comes down to it. Otherwise if it's just a matter of not having an Apple monitor more suited to this particular machine then I'll go on the hunt for one!
