Differences in 144hz monitors

[msterforks]

I'm confused as to why certain monitors have such huge price gaps. From reading the threads, there seems to be two groups of 144hz monitors, ~200 USD, and 300+ USD. The question is: why? They all feature the same 144hz refresh rate, 1ms response time, 1080p resolution, and 24" screen size. Some examples:

 

~200 USD

Another question is what the differences between these monitors are, even in the same price range. I saw a post saying that the Asus vg248qe is the best ~200 USD 144hz monitor, but without a proper reason.

The quality of the panel, Ex, Color reproduction/Viewing angles

 

the Acer GN246HL out of these is the cheapest but also the worst colors from all of these

It's all on the quality and image specs (color, angles, screen reflection, etc.) of the monitors by the looks of it, as Aytex mentioned above...you want better quality, you spend more money  usually how it works
