For me an upscaler (Medusa) removes the ghosting on the V2 too. Main advantage for me is that i can leave the cables, i have also other retro systems connected on the scart input.
In the mean time i have also found a good working 15" CRT monitor, its yellowed, but works perfect with the TC64v2 and indivision in my A4000(Yes the very first one) and the Indi ECS V2. With this setup the image quality is realy perfect and the scrolling as as smooth as on a 1084 for the Indi ECS v2 and TC64v2.
I also have some retro PC's, what i noticed on modern LCD with VGA is that newer cards tend to give a better image, while older cards like TRIO64 based also gives less good image.Now im not to technical, but my best gues is that the main focus is on HDMI input and the VGA is implemented as cheap as possible.
