27" IPS 1440p Monitor - Advice

I need a monitor for work (document creation, pdf reading and web browsing) that will allow me to have multiple windows open side by side.

I don't play games and only occasionally watch videos so I don't think I need a refresh rate above 75Hz.

I'm after a 27" monitor and am thinking IPS at 1440p best suits my needs.

Any thoughts on best / cheapest monitor that fits the bill?

Also, if you think 1440p is not necessary, would be great to hear your thoughts as there seem to be a bunch of 1080p monitors at 27".
