I used to think I had the rotation problem, but I can't see it now. Either I was seeing things before, or I accidentally fixed it by tweaking another control. Even when I thought I had the problem, it was so slight it wouldn't have changed my monitor purchase decision because of the rotation problem.
If I had it to do over again I'd still get the Betson because I know it works and I've never seen another multisync monitor to compare it against. I wish I could see a WG monitor to do my own comparison. Retorblast has reviewed them both and preferred the Betson, so I mainly just trusted his advice.
