Another adapter, this time Miro branded. It sucks. I wish i hadn't payed 10 Euros for it.

Here is a quick table of what worked with a modern display, the LG Flatron IPS224 22" TFT, wich you can get for about 150 Euros at Amazon:

Code:
Miro MC2, MacOS 7.5.5, LG IPS224 TFT

          Q650 C610 P475 IIsi
640 x 480    +    -¹   -    +
832 x 642    +    +    -    -
1024 x 768   +    +    -    -
1152 x 870   +    +    -    -
Msync  640   -    -²   -    +
Msync  832   -    -    -    +³
Msync 1152   -    -²   -    +³

+) Works!
-) Monitor stays blank, thinks no signal is there
¹) Monitor says out of Spec
²) Until MacOS starts, then it goes blank
³) 640 x 480 only
I also tested another display, a HP 1955 19" TFT, wich in it's documentation claims to support Mac modes 832x642 and 1152x870 and even a Sun mode. However, with this adapter it didn't work at all.

It works fine with another adapter and i can recommend the display. It's very cheap, you can get it used at Ebay for 20 Euros. The robust VESA-Stand (with pivot) is worth it alone. I only wish i had the 17" model, wich electronically is the same, but in a smaller display.
