If you end up without network, check /sys/class/net/ if the device name has changed and change it accordingly in /etc/network/interfaces .... as you run a server this should be peanuts for you.

It seams that the kernel you linked solved the problem. xrandr --verbose confirm it is RGB full. Kodi is set to Limited, and Dithering is turned ON (8), picture is excellent. It remains good even after turning off and turning on the tv. I need to compile drivers for the usb tv card again. I have a budget phone now, no sense to make pictures But will get my dslr and make few shots.

I had to change the network interface indeed. I'm running a small home server, but I'm very n00b, learning a lot. Its a very simple one, but makes everything I need.

Edit 2: One n00b question: I need to select this kernel at startup each time in advanced. How can I make this the default kernel?
I solved this.
