What brand/model monitors are you using?
These are Samsung 275Tplus. It's increasingly hard to find monitors with 1200 vertical res these days — at least I find it so.
I've found Samsung, the company, totally unpleasant to deal with, incompetent, careless of their customers, and slipshod. I'd avoid them and their products if I could. Unfortunately, when I bought these, one of a pair of previous Samsung 1600x1200s had failed and they could produce only an unsatisfactory replacement under guarantee. Needless to say, that didn't match the remaining functional monitor. So, I needed a matched pair of reasonably large screens in a hurry and these were the best of what my local supplier could deliver the following day. (I gave the remaining monitor from the previous pair to my wife and she's happy with it, and it's still going strong.)
The downside with multiple screens is that when one of them fails it's often necessary to buy another set
of screens because the current models don't match the previous ones. As you know, models change very fast and a screen more than a year old will probably be difficult to replace with an exact counterpart. I don't like working with mismatched screens.
The up side of equipment failure is that one can use it as an excuse to upgrade.
I'm quite pleased with these screens, precise colour matching isn't crucial to me, so I can afford to be less fussy than some. As I said previously, they provide quite a lot of real estate, almost all of which I can see at a glance.
