Hi DGB,
Had the same problem with my A2000. The screens looked "Crappy" to say the least. Solved that by getting a graphics card, mines's a CGX64_3 d. It's in the "Bits", 8 bit graphics looks bad, 16 or 24 bit looks "Great". Took me a while to figure it out, but, it's worth it, believe me. Best regads...Art
