Hi guys, looking for a pair of screen to make a dual screen

Purpose: Programming, designing, occasional gaming, watching movies

Specs:
Resolution: 1920x1080 at least
Size: 21-23 inch (if too big, then, my desk won't fit the two screen! My desk is like 47 inch wide or 1.2m wide)
Ports: Preferably all three: VGA, DVI, HDMI
Refresh rates: 60Hz (is it enough?)
Response time: 5ms or lower

Budget: RM1k for both screens. Cheaper is better I guess...

Many thanks!
