Which is a better resolution???

Re: Which is a better resolution???

Then why is there even a choice of refresh rates if it doesn't effect performance? Why aren't the monitors automatically on a high refresh rate?

for some reason having 75hz vs 60 hz on my lcd monitor makes things look sharper

Laziness? Any modern CRT is autosync anyway, and as long as it is PNP (plug and play), it should negotiate with windows to set the refresh rate based on the resolution selected. But some hardware still needs manual intervention, and some rendering engines override these settings.

The required refresh rate is (roughly):
Vertical Scan Frequency (refresh rate)=Horizontal scan frequency/#horizontal lines (vertical resolution)*.95

So, a CRT with a HSF of 96KHz, at 1280x1024, gets:
96000/1025*.95=89Hz refresh rate requirement.

Running a CRT with a higher refresh rate than required by the resolution is a bad idea - it puts extra work on the components, and can make the image slightly blurier, so set the refresh rate in the graphics driver to an appropriate level if PNP isn't doing it.

LCD doesn't matter - see earlier posts.

Do be careful, if you experiment with manual overrides of anything using a CRT - you can fry your CRT if you do the wrong thing.
