I value a height adjustable stand and wouldn't buy a monitor without one.
Well, finally one area where we are in complete agreement!
I can't raise or lower the height of my desk. And I set the height of my chair based on my body and keyboard height. A ream of paper under a monitor looks silly - assuming the monitor would still fit under my desk's hutch. So my monitors must have height adjustment. Sadly, most monitors have a fixed height.
I never tried curved and not really interested in curvature.
Then don't get a curved monitor. Setting aside the fact they tend to cost more, they do not provide superior image quality. It is all about the "experience" - which can be great! But is it worth it? To achieve that optimal experience with a curved monitor, you
must sit and plant your head in the viewing "sweet spot". That sweet spot is a specific number of inches from the center of the screen. Move in or out too far, and the optimal "viewing angles" of left and right sides of the display are quickly exceeded. Move your head slightly off center, and the optimal viewing angles for the sides are once again, exceeded. To maintain the perfect viewing angles and distance from the screen, you might as well clamp your head in a vise!
Okay, its not that bad and I suspect with a little time, you can get used to it. But for me, I want the flexibility to move around a bit. So I would rather have two flat screen monitors instead of a larger curved monitor. Just go for monitors with thin bezels and I promise, soon you won't even know the bezels are even there.
I can't stand integrated speakers in monitors either. They may be fine for Windows system sounds, but nothing more. IMO, they are waste of money and space - even more so in multi-monitor setups. But integrated speakers are for another discussion.
One more thing to consider with a curved monitor is multiple viewers. There is only one sweet spot with a curved monitor so a curved monitor can only provide an ideal image for one viewer sitting directly in front of the center of the screen. I note multiple viewers in the TV room is exactly why curved big screen TVs have not had the sales numbers marketing weenies had hoped for.
Don't forget to make sure your graphics card has the necessary graphics port to support any monitor you are considering.
