looking for a second monitor, under £200

[llyr1900]

In short, I already have 1 monitor at the moment that I'm gaming and watching movies on.
Im wanting to get a second that I can use for gaming only and ill be watching movies at the same time on the other. I'd like it to be around 23 inches and depending on price, hopefully 1440p. I'm using a sapphire r9 290 tri x so I assume I won't have much of a problem running it.

Thanks for help in advance
