2001 FP tech question (more on eyestrain)

RainDog · #1 08-01-2005, 12:06 AM

First of all, my eyes have been very happy since I purchased the 2001FP. However, after reading a post concerning high eye strain at a refresh rate of 60Hz I decided to check the refresh rate I was getting with the 2001FP at 1600x1200 resolution. I was surprised that though the monitor's max sync rate in the specs was 76 Hz x 80 KHz all I had was an option for 60 Hz. I then downloaded the official driver and did away with the plug and play driver thinking there would be a difference, but still my only option was 60Hz. I then unchecked the box that says "Hide modes that this monitor cannot display" and was then able to select a higher refresh rate. So my question is, am I actually getting a higher refresh rate or is it really still maxed out at 60 for this resolution? Also, what refresh rate should I select if I actually am able to go higher...75? Or do I not need to worry about refresh rates for an LCD, since they refresh differently than CRTs? Thanks guys, just tech curious here.

I'm pretty sure 60 is just fine for an LCD. 75 and up only applies for CRTs.

Ignore refresh rate with LCDs. There is a long-winded techy response as to why, but it's not important.

The techy bit is not that long winded. The electron gun in a CRT scans down the screen 60 times a second (at least), lighting up each pixel as it passes, the phosphor glows and gradually dims over the next ~ 1/60th second. It is this change in brightness that causes flickering and eyestrain.
On an LCD, every pixel is always lit, only the color is changed (if needed) 60 times a second.
