I just installed a Viewsonic VA720 LCD Flatscreen. I've noticed that the loading of webpages, etc. is MUCH slower; is it possible that the clock speed on the GPU is too fast (read that in booklet) for this monitor. The booklet says it should be no higher than 75mhz and if I'm reading the Spec program correctly it is currently set to 125mhz.

Any other possiblities ? 256RAM. Dell Dimension XPS B100r.

Thanks, Mark

If you have the refresh rate set too high, I believe you could destroy the new LCD. I would adjust the settings down to 75Mhz immediately....

Unless you're overclocking, you never touch the speed of your GPU. In fact, you usually can't. It wouldn't matter anyway since your video card's speed has nothing to do with your internet speed.

I suspect that what you were reading about in that booklet was the refresh rate in Windows. CRT's are analog and require a refresh rate, but LCD's are digital and don't really need a refresh rate. However, they accept the signal and ignore it, within limits.

Standard refresh rate for Windows is a painful 60Hz. I guess 75Hz is the max for your particular LCD monitor (perhaps most of them).

Warning: More technical nit-picks incoming.

The refresh rate and clock speeds are two different measurements. The refresh rate is the amount of times per second the monitor "redraws" your display while the GPU clock speed is the actual processing speed of your video card and is independent of the refresh rate and vice-versa.

While GPU clock speeds are measured in MHz (millions of cycles per second), refresh rates are measured in Hz (cycles per second).

Just realized we still haven't addressed your primary question.

Unless you installed special drivers/utilities that add color management and extra display tweaks to your CPU’s responsibility, there shouldn't be any related slowdowns in performance, and web-browsing speed shouldn't be affected at all. Even with extra utilities, unless you're running a Pentium 200 with and old video card, there shouldn't be any noticeable performance hits.
