Dear sifus, need some advice on purchasing a 2nd monitor. The monitor is mainly for watching videos and browsing. Currently have a Dell U2312hm already as my main. I mean, I don't mind if it is good enough I can game with it as well, but I'm assuming my Dell is better suited for that?

Criterias:
22-23 inches
1080p Full HD IPS
RM400-500

Been doing some research and found:

Acer R231 RM 499
and
Viewsonic VX2363Smhl RM 549

Both on lazada for those prices. Can get 10% off using UOB and lazada app if order today.

Any comments on the difference? Which is the best bang for my buck? Would appreciate your input. Thanks in advance!
