"... the blame game". No. I'm saying we can't move forward with this until you are willing to accept that the problem is your computer, not the monitor. If you're trying to "cover all the bases", well, I haven't seen that so far. You've been stuck on one base, the monitor.
I don't know whether I can fix the problem. The forum is about people helping people. If I can't come up with the solution, then maybe someone else can. But, an open mind and some clear thinking and communicating are needed, whether here or in any other forum, in order for progress to occur.
"But it's clear you don't know." Wrong. You don't know what I know because you haven't allowed the discussion to continue beyond the notion that you have a monitor problem.
