I have received my minimig lately and wanted to play it on a TFT monitor. After quite some searching, I managed to find a monitor which accepts 50hz AND has the option to view the image at its native aspect ratio.
These are my findings with the G2020HD being used with a minimig:
PRO
1. Had no problems to sync at 50hz and gave me a nice crisp picture
2. No blurring!
3. Has option to display in 4:3 as per original aspect
4. Vertical scrolling is perfect (tested with pinball dreams!

)
CONS
1. Horizontal scrolling for some reason is not perfect, I can notice a slight tearing effect every 1 cm or so. Its not that bad, after a while you stop noticing it..... but it would have been great if it wasnt there (noticed it in Silkworm, Project X)
Maybe someone can tell me why this happens.
To sum it up, I think its hard to find a better TFT monitor than this one.
