Vertical lines with different pcbs

It is quite likely that either the scaler you bought or the one in the LCD monitor are to blame.
The hardware in your monitor is probably trying to deinterlace your signal while it shouldn't.
Is your signal coming into the monitor through VGA or through scart/component?

EDIT: obtw... LCDs all have scalers inside, and this sucks. Arcades are best viewed on CRTs with a wide vertical frequency range.

I don't have a scaler yet. Yes, it's most likely caused by the LCD internal scaler. I bought a scaler, it's coming from china. I will test it when it arrives.
Yes. I know CRTs are better for arcades, but I don't have one right now.

PD:The signal is coming from the SCART cable.

It seems it was a resolution issue withe LDC screen. Now, with the GBS8200 the image looks better.

I'll drop this just to illustrate how changing the algorithm of the deinterlacer can affect the image quality when stuff is blinking in the image.

With "complex" MoComp" algorithm:

With "old game" algorithm:

Old game algorithm is not doubling the image size.
