Problem with Macbook Pro and external Monitor

The 208Hz refers to the video bandwidth, not the refresh rate. 60Hz I believe is pretty normal for LCD screens. There's not much (if any) point in going higher.

 

Refresh rate on an LCD means something competely different than for CRT's. 5ms refers to how quickly a single pixel can change colour, it has nothing to do with how quickly the whole screen is refreshed.

As the guy above says 60Hz is normal for an LCD and does not have any bearing on the 5ms refresh rate of the individual pixels. Everything is fine, carry on.

 

Forget about full screen refresh, it's not something you have to worry about with LCDs.

The faster the individual pixels refresh on an LCD the better movement will look. Slower screens mean that as something moves across the screen the pixels take a visibly noticeable time to change colour - this results in ghosting behind the moving object. 5ms is very bloody good. The shortest I've seen is 4ms although most people say they can't tell the difference between 8ms and 4ms screens so the extra money for the quicker screen isn't really worth it - although for gamers and video people it would make a big difference I suppose.

Does the screen look OK now?

 

Refresh rate for an LCD monitor basically doesn't matter, because the pixels are all on all the time.

Refresh rate really refers to the number of times per second the electron gun in a CRT could sweep over the screen and reenergize all the phosphors on the screen.

Since all the pixels in an LCD are on all the time, the individual pixel rate is more important as they are all responding independently to input. If you have changes on your screen that take less time than your LCD's pixel refresh rate, you will notice. Like in 3D games where ghosting will occur.

 

Because your other questions have been answered relatively accurately, I'll focus on this one. The basic idea is that the higher the resolution, the longer the electron gun takes to make a pass in a CRT.

For example, if you run a given monitor at 768 lines, the gun can refresh at say, 100Hz. If that monitor supports 1200 lines, the gun's beam has to compress into a smaller vertical confinement, but the movement of the gun stays at roughly the same speed, which means that the overal refresh movement is slower as a result.

Of course, none of this is applicable to LCD displays.
