Quick Refresh rate question

My Monitor can support 60, 70 and 72 hz, does increasing from 60 to 70 in anyway decrease performance?

No it doesn't. Your proformance will be better if anything.

Put it onto the highest refresh rate it can go.

Looking at a monitor running at 60Hz for an extended period of time will give you headaches and eye strain.

Thanks, I was wondering about that for a while. I tried it on 72hz but the picture was a little screwed up so I put it on 70hz and its running fine.

60Hz is for less power usage.
70Hz for me since I can't stand the flicker from 60Hz.

LCD is completely different than CRT display. doesnt matter if u have 60hz or more on LCD.

Don't know about LCD, but TFTs has 60 and 75Hz. I use 75Hz of course, always use the highest refresh rate for the given resolution. Also, a resolution very high will produce a low freq, so for 17" i would suggest 1280 at 75 much better than 1600 at 60.

For CRT monitors, the highest refresh rate for the resolution you are using is the best. You may have to use the little adjustment buttons on the front of the monitor to get the picture right on the screen, but the picture will be better and games can actually play better.

For LCD monitors, they are happy to run at 60Hz...The technology they use isn't really tied to its refresh rate.
