Color and sharpness on external monitor noticeably inferior to Macbook monitor

[Axemantitan]

I have a mid-2007 Macbook and I bought this Asus display and hooked it up as a second display. I connected it via HDMI and an HDMI to mini-DVI adapter. I calibrated the display in Displays preferences and tried different resolutions, but it still looks inferior to the Macbook display right next to it. Is there anything that I can do to sharpen the picture?

Also, what does the "overscan" option in Displays preferences do? It's checked by default, and I have left it on.

I think I'm having the same problem here, have you had your problem resolved? Thx.

Turn off overscan and set it to it's native resolution.

I believe the problem is the macbook's being limited to 1080p over an HDMI connection. When I ran into this problem a couple years ago, I found that using a mini-DP-to-DVI-D adapter and a DVI-D/DVI-D cable to connect to the DVI-D port on my monitor instantly fixed the problem. I'm still running the same arrangement today.
