I have an Indivision A1200 and gives my some ghosting on my Samsung Synchmaster 941 MW. A few monts ago I bought a secondhand AverMedia TVBox W9 and I got a screen without ghosting and crisper.
This might be an alternative solution to connect older scandoublers to your LCD monitor or TV.
Yeah i have both the Indivision 1200 and the Indivision 4000.
On the same LCD screen, with the same external switch and same type of cable, the display is far better on the 4000 than the 1200.
I think this is related to the ground connection missing on the 1200 version and present on the 4000 version.
I hope that this issue will be fixed on the expected Indi MK2, as i will certainly buy one for my other 1200.
