General scan doubler question.

[RMK305]

I'm planning to get a scan doubler and a  switcher box to use with the CV64 3D. I've found a Mikronic scandy internal unit for £45 which seems reasonable. However, I've read a review that states that this card shifts the image to the right of the screen and the reviewer stated he had to use the monitors controls to correct this. Do all scan doublers suffer from things like this? I'd rather not have to adjust the monitor everytime it switches from GFX card to scan doubled output.

Thanks.

It's an old style crt monitor. I'll maybe just go for the scandy and see how it goes. I'll just sell it on if it doesn't work how I want it to.
