I know most the difference between them from reading the post past month or so..the only concern I have is scaler...i will be using the monitor at 2560x1440 and probably use ctrl & + to zoom in the text size as the text would be too small to read at such resolution... sometimes i watch blu ray movies..but that's about it. I tried to look up already..but exactly what i will be missing without scaler? could anyone gives some examples on scaler issue? thanks
