and this one:

Has a true VGA input!!! I have just written an email to K-World... asking for more info:

I was wondering about using the "TV BOX WS-PRO HD" as a Scan Doubler/Flicker Fixer for my old Amiga computer (if you know it...)...
I notice your device has a VGA input... which signal can accept (and process)...?
I would need for example to convert four main formats:
15 kHz horizontal frequency, 640×512, flickering
15 kHz horizontal frequency, 320×512, flickering
15 kHz horizontal frequency, 640×256
15 kHz horizontal frequency, 320×256
from a VGA input into your device (for best signal) to a standard VGA output!

Let's see...
