Sadly I have to agree that 16:10 is a fading format. Pity, because when you actually want to, you know, do some work, it turns out that a bit of extra height isn't a bad thing... but there's more pixels per diagonal inch than with 16:9, so manufacturers have jumped on the cheaper option and convinced the world it's what we want :/
I've actually got a price watch on a 30" Iiyama IPS which probably shares a panel with the OP's HP. The frustrating thing is they're damn nigh as expensive as a 32" 4k screen - and twice the price of a 32" 1440p VA panel.
I would love to see new, good quality, 16:10 screens, but I think we'll just have to bite the bullet and let them go
How about 31.5" & 32" 4K 3840x2160 monitors
Is 16:9 and a pain in the bum to drive at full resolution for gaming though :/
