Easy to find monitors curved in one axis, but this wastes all the vertical space! The optimal shape would obviously be a spherical-section. (Of course this means your windows can't be rectangles anymore... IDK, make the GPU figure it out.)

DIY or extremely high-end projects don't count, it must be consumer-focused. Other things that are obviously not in the spirit of the market also don't count.

For example I would not accept flight simulator hardware that costs $200,000 and is incompatible with my laptop. Nor would I accept a postage-stamp-size spherical screen. It must be reasonably useable for normal computer work, like a normal monitor.

Resolves NO if no one finds one by close.
