Monitors are a sort of special arena of contention among our types, but I gotta recommend the Dell Ultrasharp U2415 24 inch model. Native 1920x1200 at a DPI I feel comfortable with. The trick here is that it has the DisplayPort inputs and outputs needed to properly daisy chain the monitors. Then you just need to get a high data rate DP cable (Rankie DP 4K Resolution cables are legit and cheap). The crazy that follows from bad standards and misleading specs caused me all sorts of heartache.

Have you seen the new MacBook prob? It's even more impressive in this area
