I used 60 Mhz VIDC frequency in my A5000 and it worked quite well with
1024x768x16x60Hz. And even the normal A5000 monitor did it. But I have
one BIG problem, the VIDC is too slow for that. Meaning I have to cool
it all the time using cooling-spray ("Kaeltespray" in german but I think
you'll understand what I mean) because the silicon based microchips are
fastest at about 0 oC. 
Does someone know if there is a faster VIDC available or how to cool it
permanently to 0 oC.
