My question about finding a KVM that meets my needs was closed. Superuser seemed like the best place for the question because it was about computer hardware. The issues involved are technical and complex so the insight of the community here would be very helpful.
Since I have not purchased the KVM, it is fair to call it a "shopping" question. But really it is about avoiding hardware incompatibility.
Is it allowed way to ask a question of the form: "I need to use X, Y, and Z together in a system. My research indicates various reported issues with incompatibilities. Can anyone report on specific products for X, Y, and Z that are working together properly for you?"
If not Superuser, is there any Stack Exchange site where such a question could be posted?
