Hi, Just received this card and placed it in my A1200.
Things started well at first but within a few seconds the screen started to flicker and became unstable. I tried 2 monitors and HDMI and VGA - all with the same result.
I inserted my MK2CR into the same A1200 and it works fine.
Sadly it looks like I have a faulty one??
Two videos one of the mk3 and another of the mk2
