There aren't any AFAIK, the smallest 1440P monitor I have seen is 25inch, there is one from Asus as well as Acer. The Acer one is about 260$ and the Asus one is about 370$.

Are you trolling or what? Do you not know what will happen once you nuke such a large region or the world? Are you like 12 or have you not been outside?
I am not sure about Thermaltake's warranty service. If you can afford the TK I would buy that because possible better quality over time. But if you want to save money ZX is the way to go.
