Thnx for your help, I really Appreciate it.
For now I borrowed a König scanconverter
and it works.
So at least I got something to go on for now.
But as you said fruitygreen it doesn't support the dimensions which I prefer. But at least it works and gives me more time to find a more suitable solution.
I also had a look on this VGA to HDMI converter
Emailed the seller who told me it doesn't add a hdcp signal.
So maybe this is worth a try to get better quality and dimensions.
And I will certainly have a look at the HDFury box.
Allready stumbled upon that on my search for possible solutions.
But am I looking at a product like Dr. HDMI
If I may ask, what HDFury are you using Fruity?
