I'm finding that my 386 is giving a display output that seems to "shimmer" sometimes in some places. Like the effect of hot air rising from a tarmac road.
I'm using a few KVMs but when I swap the 386 to the other cable of the KVM pair it is on, there is no change. Meanwhile putting a different PC onto the 386's position, does not lead to the effect on the other PC. So I conclude the is not a fundamental problem with the KVM or cabling.
I didn't get this effect a few weeks back so I wondered if I needed to reseat the vga card [tried that] or move it to a different slot such as away from the NIC [tried that].
Any ideas what the problem might be?
