good refersh rate?

As you increase refresh rate the pixel clock also goes up in order to draw the pixels on the screen faster. If you monitor video amp is not capable of these higher pixel clocks, video will start to degrade as you increase refresh rates.

And / Or


Some video card manufacturers put RF filters on the output of the video signal. They do this to reduce Radio frequency interference cause by the pixel clock and video signals on the video card. These filters are designed such that they reduce RF interference as you increase the video rate and do virtually nothing at lower signal rates. As you increase the refresh rate, you are increasing the video rate and the filter circuit starts to take affect. This explains why everything looks sharp at lower refresh rate.

I have the same problem, im using Sony CPD-G520 21" and Geforce2MX

this is the problem
1. 1600 x 1200 32b @85hz = text blur
2. 1600 x 1200 32b @60hz = crisp text

is there a way to run my monitor 1600 x 1200 32b @85hz with crisp text ?

what if I change my Video card to Geforce4 4600/Ultra ? is it working ?

I'm certain the p1460 has the bandwidth to handle 1600 x 1200 at 85Hz, so that excludes #2 in my first post. Could be #1 or just plain poor focus on that particular unit. Unlike other electronics humans tune monitors so some amount of variation is inevitable.
